The construction of an apron feeder for feeding agglomerate at high temperature of 500—1000℃features are as follow: a dust-proof heat insulating cover at the inner sides of its frame to efficiently extend the service life of the bearing. Dust proof cover is easy to installation, heat dissipation and lapping tightly between the material bearing plates. There is a distance between the two sides of the traction chain, plate heat deformation doesn’t affect the normal operation of the traction chain

By analyzing the running deviation of apron feeder, and put forward the rapid tuning folk prescription apron feeder is a kind of mine auxiliary transporting equipment. This paper mainly about an analysis on the cause and solution of deviation of mining apron feeder

By analyzing the main parameter of compost trommel screen and the movement characteristic of material in the trommel screen, the method of determining the main design parameters of the trash-drum screen is put forward.

Sidewall belt conveyor consists of corrugated sidewall belt and diaphragm plate. As a kind of bulking material conveying machinary, sidewall belt conveyor has large conveyor inclined angle, it is the ideal equipment for conveying and lifting materials with large inclination angle. It can reduce the space and equipment investment, it has high economic efficiency, and widely used in coal, mining, grain, metallurgy, chemical and other industries. Besides, it also used in dry mix mortar production line to conveying the aggregate.

Sidewall belt conveyor not only has the features of large capacity, long conveying distance, low working friction, high efficiency, but also has the high lifting heighth, save space, simple structure, low invest cost. Sidewall belt conveyor is suitable for convey coal, sand, grain, cement and other materials.

This paper mainly introduce the improvement of lubrication method of inclined screen bearing. According to analysing the practical example of dressing mill, the reasons and improvement measures of the bearing damage are provided.

When the screening equipment of the gum production line is in operation，there are a large number of material particles which are small enough but can’t get through the screen cloth in time. These materials will then be shattered repeatedly to make a lot of materials with particle sizes smaller than 0.038 mm，therefore the quality of the products is influenced. To solve this problem，a study of the structure and operating principle of the vibratory separator is done. A new and high-efficient vibratory separator is designed，base on the structure of ordinary vibratory separator.
