|The whole system of vertical roller mill is mainly composed of main mill, analyzer, dust remover, pipeline conveying device and main motor. The fineness of the finished product is even, the screening rate is high, and the three-dimensional structure is strong. The main machine is mainly composed of frame, air inlet volute, blade, grinding roller, grinding ring, housing and motor.
The fineness of the vertical roller mill is even in the process of grinding, the screening rate is 99%, the main engine transmission adopts closed gear box and pulley, Smooth transmission, safe and reliable operation, The electrical system is controlled centrally, The grinding workshop can be completely unmanned, And maintenance is also very convenient, vertical roller mill as a whole presents three-dimensional structure, occupies a small area, sets of strong performance, from the bulk material finished powder independent of a production system, the important parts are made of high-quality steel, wear-resistant parts are made of high-performance wear-resistant materials, the machine has high wear-resistant performance, safe and reliable operation. Before starting the mill, all the access doors shall be checked for tightness, and the mill shall be checked for conformity with the feed grain size, so as to adjust the rotation speed of the analyzer to meet the requirement of near finished grain size. After starting the mill, the vertical roller mill shall be started in the order of grinding, and the vertical roller mill shall be shut down in the following order when stopping the mill:
1. Close the feeder first and stop feeding;
2, stop that host after about one minute;
3. Stop the blower after blowing off the residual powder;
4. Shut down the analyzer afterwards.
Vertical roller mill can not be refueled at will during normal operation. It is necessary to ensure production safety. If abnormal noise occurs in any part of the mill or the load increases suddenly, stop the mill immediately for inspection and troubleshooting so as to avoid major accidents. When starting the mill again, the residual materials in the mill must be taken out, otherwise the starting current will be too large and affect the start-up.|
