Vibratory separator is characterized by fine screening,suitable for high classification requirements of materials,it can be divided into 6 levels at most,so you need to operate in accordance with the requirements,such as:the installation of screen,the selection of screen mesh ,the adjustment of phase angle,and other operate cautions.

Trommel screen is one of the most commonly used sieve equipment in solid waste treatment. Solid waste is classified according to particle size by screen body, and the screen body is installed obliquely when working. The solid waste entering the screen moves helically with the turning action of the sieve body. Under the action of gravity, the solid waste with particle size smaller than the sieve hole passes through the sieve hole and is screened under, while the solid waste larger than the sieve hole is discharged at the bottom of the sieve body.

Heavy duty apron feeder is widely used in mining,metallurgy,electric power,coal and etc industries because of its large feeding capacity,can withstand the direct impact of the large lump materials and the stable performance.it is not only suitable for the treatment of coarse material,fine material is also adaptability to the change of particle size,composition,temperature,viscosity,influence of frost,rain and snow or frozen material.uniform,accurate and reliable feed quantity.

The main structure of GTS series trommel screen is screening drum ,it is composed of thousands of round screens,the screen surface is generally composed of woven mesh or perforated sheet and frame,the whole trommel screen and the ground plane into an inclined state,with many advantages,such as:wide applicability of materials,High screening efficiency,large screening capacity,the low energy consumption,low noise,long service life,convenient maintenance and so on.

At present, Chinese belt conveyor roller sealing structure is labyrinth seal form,It is necessary to combine the labyrinth seal with other seal forms so as to effectively improve the working efficiency of the roller In the design of the sealing structure. there are also some other special seal structure which are basically used in a specific environment.

belt bucket elevator is a continuous conveying machine that uses a series of buckets fixed uniformly on the endless traction members to lift materials vertically. belt bucket elevator is widely used in building materials, chemical industry, grain, gold, coal, electricity and other industries, used to lift all kinds of bulk materials.

Adopt trommel screen to classify the camellia olefin according to their different size can effectively reduce the rate of damage and improve the rate and clarity of shucking.

the belt conveyor is composed of the driving pulley,bend pulley,idlers,driving device and the conveyor belt and so on,the idler is the most widely used and distributed component of belt conveyor,generally distributed throughout the whole belt conveyor,and its mass accounts for about 1/3 of the whole belt conveyor,therefore,the reasonable spacing of idlers is set can play a good supporting role for the conveying belt,ensure that the conveying belt always keeps the sag state,effectively reduce the running resistance,and achieve the goal of smooth operation of the whole belt conveyor.

The effects of vibration parameters on particle screening efficiency were studied by using dried silicon powder, molybdenum powder and zinc powder as typical materials, which is helpful to solve the problem of screen hole block and improve the screening efficiency of vibratory separator.

When the users using the vibrator separator,encounters low screening yield , the material cannot be screened down and the material cannot be discharged, the vibrator separator can be adjusted according to the situation of field use,they can adjust the angle of vibration motor,through adjust the phase angle of heavy hammer can change the material on the screen movement locus and standing time,thus changing the running track of the material and screening accuracy of the vibratory separator

XZS type vibratory separator adopts motor rotation to generate excitation force so that the screen body produces repeated type vibration. Its motion trajectory is a complex spatial three-dimensional curve. By adjusting the space and position angle of the upper and lower counter weight, it can effectively change the movement trajectory of materials, extend or shorten the residence time of materials on the screen, so as to achieve the ideal screening effect.

Rare earth powder sieving is an auxiliary process, but it not only determines the quality of the final commodity, but also has an important impact on product yield and environmental protection.Rotary vibrating sieve is an ideal choice to control the particle size of rare earth products.

Due to the long conveying time and many links in the conveying process, the crushing of bulk grain is unavoidable, and the crushing rate is as high as 35% in the conveying process in serious cases. Therefore, it is urgent for grain depot to solve this problem. The main reason for the higher grain crushing rate is that the structure design of trough chain conveyor is not reasonable enough in the conveying process. So it is necessary to strengthen the debugging and transformation of the grain conveying system, reduce the damage rate, avoid grain waste and improve economic benefits.

Along with the people to the value of sanitary conditions of grain feed stuffs, more and more people pay attention to the sanitary of food and feed processing equipment, which means in the process of each link of the discharge process, material requires no residue, no cross pollution, and the equipment requires simple mechanism and reliable operation. The new type of trough chain conveyor without material residue can realize material discharge without residue, avoid material cross contamination and material deterioration, and improve material quality.

As a new type of lifting product developed by introducing foreign advanced technology, chain bucket lifter is widely used in various industrial countries due to its features of energy saving, high efficiency, low noise and long service life. The chain bucket elevator is an inflow feeder, and the material flows into the hopper and is lifted to the top by the chain, and discharge by itself under the action of gravity of the material. Chain bucket elevator often has the phenomenon of chain plate falling off and cracking in the process of production.
