Raymond Mill Working Principle. The Raymond Mill is mainly composed of a host, an analytical machine, a fan, a finished-product cyclone collector, a fine-powder cyclone collector and air ducts. Of them, the host is made up of a frame, an inlet volute, a shovel blade,.
The rotary kiln line, raw mill and coal mill were being operated by a PLC based central automation system in the plant. In general, it is quite difficult to ensure process control with such a conventional automation system, looking at long term stability and consistency, due to shift-to-shift variations.
Especially in the coal industry, using this machine to crush raw coal, it can be directly crushed only after removing iron, impurities and without gangue. The crushed materials have an average particle size and a low over-crushing rate, which simplifies the coal preparation process. Reduced investment and production costs.
High energy efficiency. Compared with a conventional grinding system, the Hydraulic Roller Press can reduce specific energy consumption by 30 percent. The two-stage separator has low power consumption of the separator fan and helps to maintain high energy efficiency of the overall grinding station. High availability and reliability.
