Roller Mill Coal Grinder
- Description
-
The MPS(MP) type roller disc coal mill is a high-efficiency and energy-saving coal mill, suitable for grinding medium-hard materials such as bituminous coal, and can be widely used in the pulverizing systems of industries such as power, metallurgy, building materials, and chemicals.
Our company introduced a complete set of design, manufacturing, and inspection technology for three specifications of MPS roller disc coal mills from Babcock in West Germany in 1985. After digesting and absorbing the introduced technology, we independently developed a series of roller disc coal mill products ranging from MP1000 to MP2650, and have formed mass production, capable of undertaking the design and manufacturing tasks of any specifications and types of MPS(MP) type coal mills.

The MPS and MP type coal mills mainly consist of the foundation part, reducer, lower frame, middle frame, grinding disc, grinding roller, pressing device, separator, positive pressure air sealing device, steam purging device, and other components. They are also equipped with main motors, lubrication oil stations, hydraulic stations, and sealing fans, along with slow-speed transmission devices, special tools for installation and maintenance, ladder platforms, coal powder distributors, quick shut-off valves, and other supporting equipment for users to choose from.
Working Principle of Roller Disc Coal Mill
The MPS and MP type coal mills are a type of three-roller force-added coal mill, where the three grinding rollers are driven by the rotating grinding disc to perform grinding operations. The material to be ground falls onto the grinding disc through the central coal drop pipe, and the centrifugal force generated by the rotating grinding disc transports it to the grinding roller path for grinding. The grinding pressure is generated by springs or hydraulic pressing devices, and through a statically determined three-point system, the grinding force is evenly transmitted to the three grinding rollers, with the pressure transmitted to the foundation through the pressing system. The drying and transportation of coal powder are carried out using hot air. Hot air is evenly distributed around the grinding disc through the nozzle ring, drying the ground material and transporting it to the separator at the top of the mill. The coarse and fine powders are separated here. The fine powder is discharged from the mill, while the coarse powder is returned to the mill for regrinding. Some uncrushable materials in the material can be discharged through the discharge port at the bottom of the mill.
