Case Summary:
At the end of 2016, a mining company in Anhui Province reached an agreement with SBM of a 200,000TPY desulfurization agent grinding plant, and it was successfully put into operation in November 2016.

Production Process:
1) Feeding System
The limestone in the hopper is fed into the bucket elevator by the belt conveyor (with the addition of iron). The hoist will send the material to the raw material bin to be ground. The lower part of the raw material bin is equipped with the belt feeder, and the material is fed into the mill.
2) Grinding System
Material is sent into the mill for grinding, then the finished product is collected into the cyclone collector and pulse dust collector through the separator, and is put into the screw conveyor from the lower discharge port.
3) Finished Product Delivery System
Screw conveyor outlet is installed with a pneumatic conveying system to deliver the finished product to the finished product warehouse. The excess gas is filtered by the warehouse top filter.
4) Dust Removal System
The whole system is equipped with three pulse dust collector. There are suction outlets installed in all dust point to ensure that the entire system is free of dust and leakage, and can achieve dust-free operation on site.
5) Control System
The system configures intelligent PLC control cabinet and host computer, to achieve the function to start and stop, monitor, interlock linkage the entire system of all the equipment, and reserves DNS interface which can achieve remote control.
