Features

The steel grit is spewed onto the roll surface by centrifugal acceleration of high-speed rotating shot blasting device, the roller surface is textured with high quality. The shot blasting device is directly connected with the motor. The movement of shot blasting device, shot material ejection and roll rotation can be adjusted by frequency control. Rotary vibration screen automatically separate shot and large particle impurities, shot speed selection control, shot blasting quantity is precisely controlled, electric is controlled by PLC, so that the roughness after texturing is controllable. The filter cartridge is installed with back purging device for dust removal. Featuring easy but safe operation, it has reliable and efficient performance, and is environment friendly. It suits for texturing the roll surface in metallurgical rolling mill and skin-pass mill.
