working principle
Application: widely used in electric power, mining, metallurgy, building materials, chemical industry, garbage and other production industries. It is commonly used in the classification of refractory materials, coal, fertilizer, sand yard stone, and screening of sticky and wet materials such as coal, coke, lime, placer gold ore, garbage, etc., so as to make the product structure more uniform and meet the production needs.
1、 Overview of drum screen
Drum screen is a kind of screening equipment which is classified according to the particle size of materials. It is also called drum screen. Because of its simple process layout, it is widely used in the product classification of mining, building materials, transportation, energy, chemical industry and other industries. It is commonly used in the grading and screening of medium and fine materials to improve the quality of materials. According to the different actual situation of users, the company can customize various types and specifications of roller screen.
2、 Structural features of drum screen
The drum screen is mainly composed of motor, reducer, drum device, frame, sealing cover and inlet and outlet. The drum device is mounted on the rack in an inclined way. The motor is connected with the roller device through the reducer through the coupling and drives the roller device to rotate around its axis. When the materials enter the drum device, due to the tilt and rotation of the drum device, the materials on the screen surface are turned and rolled, so that the qualified materials (products under the screen) are discharged through the outlet at the bottom of the rear end of the drum, and the unqualified materials (products on the screen) are discharged through the discharge port at the tail of the drum. Due to the overturning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from blocking.
3、 Application scope of drum screen
Drum screen is mainly used for grading the particle size of materials, which is widely used in electric power, mining, metallurgy, building materials, chemical industry and other production industries. It is commonly used in the classification of refractory, coal, chemical fertilizer, sand field stone, and screening of sticky and wet materials such as coal, coke, lime, placer gold, etc., so as to make the product structure more uniform and meet the production needs.
4、 Performance characteristics of drum screen
The drum screening machine has the characteristics of low power, low energy consumption, self cleaning device in the cylinder, not easy to block the screen hole; small space occupation, low investment cost, stable and reliable operation, high screening efficiency and large output; simple process layout, convenient installation, maintenance and operation. At the same time, it has strong adaptability to materials. It can screen materials with viscosity, high humidity, dirty, miscellaneous and other properties. The feeding mode is diversified, i.e. manual mode and mechanical transmission. It can be produced in large quantities. The central screen adopts annular flat steel ring design, with good wear resistance, long service life, simple structure and convenient maintenance.
