Drum screen for gravel grading is a kind of machines for the power plant, coking plant, building materials, metallurgy, chemical, mining and other industries and developed a special screening equipment, which overcomes the circular vibrating screen and linear sieve in the screening than the wet material clogging problem, improve the screening system yield and reliability, by the majority of users praise.
The drum screen is made up of five parts: a hexagonal roller, a machine frame, a hopper, a speed reducer and an electric motor. Broken stone into the drum, by the centrifugal force of the drum rotation and the role of the jig screening materials. One by one through various mesh sieve sieve out. Different specifications of the stone out of the screen after the funnel into the belt conveyor to the finished material. On the one hand with the rotation of the rollers is screened by the centrifugal force of the drum rotation and the role of the jig screening materials. A large particle size of the stone along the slope of the drum forward flow through the sieve of different mesh is gradually screened. The small stone to sieve out into the funnel, and then by artificial shipped or their sent to the finished pile.
Working principle of GT- series drum screen for gravel grading:
GT- series drum screen for gravel grading is mainly composed of motor, reducer, roller device, frame, sealing cover, inlet and outlet. The roller device is installed on the machine frame. The motor is connected with the roller device through a coupling through a speed reducer, and the driving roller device rotates around the axis. When the material enters the cylinder device, due to tilting and rotating drum device, so that the screen material turnover and rolling, the qualified materials (sieve products) by a cylinder cylindrical screen discharge, the unqualified materials (sieve products) by the end of the discharge roller. Because the material inside the drum turning, rolling, so that the material stuck in the sieve can be ejected, prevent clogging.
Summary of Series drum screen for gravel grading：
1.Series drum screen for gravel grading mainly vibration motor, reducer, roller device, rack, sealing cover, inlet and outlet composition.
2.The roller device is installed on the machine frame at an angle. The electric motor is connected with the drum device through the coupling through the reducer and drives the roller device to rotate about its axis.
3.Broken stone into the drum, the drum rotation by the centrifugal force and Jigging effect to screen materials.
Advantages of series drum screen for gravel grading:
1.The mesh is not easy to be blocked.
2.Stable operation, low noise.
3.Simple structure, convenient maintenance.
4.The whole machine high reliability, less one-time investment.
