Different from the principle of the general screening equipment, high frequency screen adopts the high-frequency, which, on the one hand, destructs the surface tension of pulp and the high-speed oscillation of the fine materials on th screen surface; on the other hand, accelerates the isolation of the useful minerals with large density and increases the probability of contact between the materials whose particle size is smaller than the separation granularity and the sieve, creating a better separation conditions so that the materials with large proportion and slurry can pass through the sieve to become the undersize.

High frequency screen is mainly composed of the exciter, ore slurry distributor, screen frame, rack, suspension spring and sieve. It has the following features:

1. It has high screening efficiency;

2. Small amplitude;

3. The high frequency makes its working efficiency high.

High frequency screen is widely used for the dry, wet screening, grading and dewatering of a variety materials in the mineral processing, coal preparation, chemical, brick-making, food, pharmaceutical, caustic soda, fertilizers, paper and other industries. It is also used for the grinding and classification process of the fine-grained materials in the dressing plant. Under the conditions of appropriate feeding concentration, feeding particle size as well as the proper granularity difference between the required undersize granularity and the feeding particle size, the screening efficiency of the high frequency screen can be up to 70%. Due to the high screening efficiency, it can cause a significant reduction in cyclic loading, improving the processing capacity. The screening process has strict control of the particle size of the undersize material to eliminate the adverse effect of the coarse mineral particles on the concentrate grade. In addition, the pulp has the role of density stratification under the role of the oscillation effect with high frequency and small amplitude and the small particles with high density will sink to the screen surface and pass through the screen, which can significantly improve the grade of undersize minerals.

The gravel screen uses the relative motion of granular materials and screen surface to make part of the particles through the sieve and classify sand, gravel, crushed stone and other materials be divided into different levels according to mechanical particle size.

The screening particle depends on the screen surface. There are three types of sieve surface: grate gate, plate sieve and mesh sieve. Grate gate is suitable for screening particulate material, the grate gate slit is 1.1 to 1.2 times of the diameter of material particle under sieve, generally not less than the 50 mm. Plate screen is a steel plate with holes on it, the holes are round, square or rectangular of aperture 10 to 80 mm with longer service life and non-clogging, applicable to the screening medium particles. Mesh wire is woven or welded by steel wire; the holes are square, rectangular or elongated and the common aperture is generally 6 to 85 mm, suitable for screening wet materials; it has large effective area.

Screening machine can be divided into fixed sieve and movable sieve two categories. Movable sieve also can be divided into revolving screen and vibrating screen.

Now, let“s learn something about working principle of the gravity spiral chute. Erect the gravity spiral chute, correct the vertical line, and fix the gravity spiral chute with a metal frame or wood at suitable place. Then, send the ore to the mouth of the screw top by the sand pump, and sdd additional water to adjust the concentration of ore oar. Due to the different proportion, size, and shape of ore, the ore and sand will be separated by the gravity and centrifugal force. The concentrate will flow into the concentrate bucket and be received by the pipeline, while the sand tailing will flow into the sand tailing bucket and be sent to the sand pool by the pipeline, and then being drain away by the sand pump and complete the whole process of beneficiation.

The sawdust dryer is mainly composed of the heat furnace, feeding inlet, rotating cylinder, filter cylinder, material handling pipes, cooling tube and the discharging port. The rotating cylinder is on the main roller, which is driven by the motor and the decelerating drive. The feeding inlet is located between the heat furnace and the rotating cylinder. The rotating cylinder has a fry blade and there is a piece of dam-board on the joint point of the rotating cylinder and filter cylinder. The baffle has one hole, which makes that the filter cylinder connects with the rotating cylinder on the one end and it is connected to the material handling pipe on the other end.

The airflow sawdust dryer is widely used in straw briquette fuel, charcoal machinery, wood pellet fuel, sawdust briquettes, and agricultural engineering industries.Henan Hongxing impact crusher for sale will be your best choice.

Due to the above structure, the sawdust in the rotation cylinder can be sufficiently dried, and the sawdust will disperse fully again before entering the conveying duct, so that the water evaporates fast. And the baffle can stop the impurities in the sawdust to guarantee the material quality in the conveying duct.

Features:

1, its drying intensity is strong; the material is highly dispersed in the gas stream, the entire surface of the particle is the effective area;

2, the drying time is short;

3, it has simple structure, small floor space and it is easy to develop and maintain;

4, the handling capacity is large, the thermal efficiency is high. When it is used to dry the unbound water, the thermal efficiency can be up to 60%.

The pin crusher is named because that the grinding medium in the cylinder is the steel bar. The pin crusher generally uses the wet overflow type and it is widely used for the first class grinding in the artificial stone sand, dressing plant, chemical plants and power sector. The barrel of the pin crusher is driven to rotate by the reducer and the decelerating drive of the surrounding gear through the motor. The barrel is equipped with appropriate grinding media – steel bars. Under the role of centrifugal force and friction, the grinding media has been lifted to a certain height, and then it will be thrown down. The materials to be grinded will enter the cylinder continuously from the feeding inlet to be grinded by the grinding media in the movement. And then the materials will be discharged out from the pin crusher through the force of overflow and continuous feeding for the next working procedure. The pin crusher has the following advantages:Henan Hongxing ore mixer will be your best choice.

Recently, the Guizhou Taian gravel production line invested by the Chinese Electric Power Construction Group and Chinese Building Materials Group these two enterprises-which also belong to the top 500 enterpries have been put into production smoothly, which marks the environmentally friendly gravel development of cement industry has become a development trend.

In the past two years, in order to conform to the country“s energy requirements , those high energy consumption, high pollution,high waste cement industries aspect all make hard efforts on the reusing resources , such as Tin Shui cement plant, Huaxin Cement factories have opened a proposed gravel aggregate production line, As a result , they not only solve the abandoned ore waste problems in cement production, but also get a new profit growth point for the cement plant, it is well described as killing two birds with one stone.

It is reported that the production line is very particular about environmental protection, environmental gravels whose daily output is 20000 tons also provided a reliable guarantee for the civil construction of a high standard of quality concrete , and this was also another yield gravel production system following the long 20,000 tons sand output per 9 days gravel production line.

We learned from a company which contracted nine gravel production line, that for assuring the energy saving, enviroment protection in the production process, they adopted two sections of a closed-circuit production process , the crushing equipment of first section adopts largecrusher, the Second stage“s equipment adopt the mineral impact crusher crushing whose domestic daily output is the first in home, the second in international, and use the vibrating feeder that have soil screening function in the feeding mouth of the first stage, each production stage is equipped with the dust removal device, the environmentally friendly effect is super , the most important is that this process is finished produced gravel particle shapes aggregate, the cleaness and stone strength are high, very suitable for high-grade infrastructure of bone The material requirements.

It seems that the gravel production of the cement and the whole field of building materials is one of the most promising flashpoint , and along with the continuously push forward of „12th Five-Year Plan, various infrastructural work started have become a foregone conclusion, so do a good environmentally friendly gravel production preparation will be the biggest bargaining chip for the future building materials market occupation.

With the development of mining machinery in recent years, its manufacturing technology and management level has made significant progress, which also promotes the development of high-end crusher in China. Currently, crusher equipment has achieved a major breakthrough in high-speed rail and urban infrastructure, cans crusher, scrap crusher and impact crusher machines enter into a rapid growth phase.

To quickly adapt to the flexible development model of crusher industry, Zhengzhou Hongxing Machinery Co., Ltd. introduces advanced technology from Germany, increases investment in research and development and concentrates on the domestic initiative and international advanced R & D projects, on the key technology of intelligence, lightweighting, energy-saving and environmental protection and on the technology innovation of core components matching technology.

According to the structure and working principle of the screening machinery, it can be roughly divided into the following categories:

(1) Fixed Screen Working part is fixed, the material screening relys on the sliding movement along the working face. Fixed grid screen is a kind of screen that applicated more in the concentrator. Which is used for the coarse crushing or medium crushing in the pre-screening. It is simple in structure, convenient manufacture, does not consume power,we can directly unload the ore to the screening surface. The main disadvantage are the followings : the productivity is low, the screening efficiency is low , which is generally only 50-60%.

(2) Roller Screen The working face is constituted by the horizontally arranged rolling shaft, there are plates on the rolling shaft ,the fine materials are obtained through the gap between rollers or plates. the bulk materials are driven by the roller to one end and finally discharged from the other end. The concentrator rarely use this sieve.

(3) the cylindrical sieve The working portion is the cylindrical shape. the entire sieve rotate around the axis of the cylinder, in the general case, the inclination cylinder axis is usually not very large . Fed into the material from one end of the cylinder, the finer level materials adopted by the screening hole of the cylindrical working surface , coarse-grained materials are discharged from the other end of the cylinder. The rotational speed of the cylindrical screen is very low, works smooth, power balance is good. But the sieve is easy to plug, screening efficiency is low, and the work area is small, productivity is low. The concentrator rarely use it to make the screening equipment.Henan Hongxing crusher mobile will be your best choice.

(4) plane motion sieve The body wobbles or vibrates in-plane . According to their their plane motion trajectory, it is divided into linear motion, circular motion, elliptical motion and complex motion. Shaking screen and vibrating sieve (different from the vibrating grizzly feeder)fall into this category. Shaking screen crank linkage as transmission parts. Motor drives the eccentric shaft rotation via a belt and pulley , so the body do the reciprocating movement along a certain direction through the connecting rod . The movement direction Perpendicular to the strut or suspended rod line ,duo to the the oscillating motion , the materials on the screening face move towards the discharge mouth at a certain speed, at the same time, the materials get screening.

Compared with the above sieves, the shaking screen has the advantages of higher productivity and high screening efficiency . The disadvantage is that the poorly balanced driving force . Concentrator rarely use it nowdays , but replaced by the vibrating sieve whose structure is more reasonable.

If we want to produce much better sand and gravel, we must rationally allocated sand making line so as to play the greatest effect of sand production line equipments. Like belt conveyor and sand maker, the speed of their work is related to the speed of the entire production line, only reasonable combination can reduce the dynamic tension of the conveyor belt, and increase transport efficiency.

Sand making equipment can provide high quality sand and gravel for the highway, high-speed railway, high-rise buildings, municipal, construction of hydroelectric dams, and concrete batching plant, which is also the first choice in the artificial sand making and stone shaping industry.

At present, the technology of conveyor develops very quickly, as manifested in two areas:

On the one hand, the functional persification of the belt conveyor, Extension of the range of applications, such as high angle belt conveyors, tubular belt conveyor, turn belt conveyors, and other models;

The other hand, the belt conveyor technology and equipment have a huge development, especially in the long interval, large capacity, high belt speed, and large-scale belt conveyor has become the main direction of development. Its core technology is developed and used in belt conveyor dynamic analysis and monitoring, which has promoted the performance and reliability of belt conveyor.

If we want to get the maximize productivity of sand making line, we should choose the high quality sand maker.

Hongxing sand maker is designed according to the principle of hierarchical crushing and incremental energy, so it has high crushing ratio, large crushing efficiency and small discharging size. It also be equipped with dynamic monitor system and application software to adjust and monitor the dynamic tension of belt conveyor and reduce security risk.

Henan Hongxing Mining Machinery Company with decades years of production experience, has established a strong sand maker R&D system, continuously promote the development of new sand making equipments by absorbing advanced production technology and core technology from abroad and combining with the professional and practical manufacturing experience and users feedback information, which has made the new type sand maker adapt to the situation and development trend of China’s economic construction, and gradually enter into the international market.

The development of crusher industry is quite rapid. With the development of market economy and the improvement of technology, crusher development experiences several different periods. The type of crusher changes several times and the performance has been greatly improved. At present, there are many types and brands of crusher. Customers are confused and blind when choosing proper equipment.

There are so many crushers with various types that customers are not sure to choose proper crusher because most of the performance is almost identical. Among these crushers, hammer crusher has the advantages of large crushing ratio, even discharging granularity and low energy consumption. However, due to the quick wear of hammer, its application in crushing hard materials has been greatly limited. In addition, grate bar is not suitable to be used for crushing material with high humidity and without clay because grate bar is so easy to be blocked. This kind of crusher is usually applied in crushing the brittle and medium-hard material, such as limestone, shale, coal, gypsum and chalk.Henan Hongxing ball making equipment, rotary calcination kiln will be your best choice.

Before purchasing the crushing equipment, what you need to do is to learn the functions of various crushers and the type of your project, thus you can find a proper crusher. According to the to-be-crushed materials and the granularity of end product, crusher can be divided into jaw type, roller type and heavy hammer type. Hammer and jaw crusher can be used to crush large material with low granularity requirement and high hardness.

Hammer crusher has the following disadvantages: loud noise and relatively high failure rate. If the requirement for the granularity and size of crushed material is not high, roller crusher will be suitable for crushing the material with low hardness. Thus it can be seen that hammer crusher plays a limited role in the further production in market economy due to its plenty of drawbacks. The further development of crusher market requires hammer crusher or jaw crusher to be transformed in performance.
