Since the first application using an MPS mill to process pulverized coal in Germany in the mid 1960s, there have been over 2,000 different MPS mill installations operating in coalfired power plants worldwide. As one of the most popular coal pulverizers in the utility industry, the MPS mill was first introduced into the US in the early 1970s.

When it comes to grinding raw coal, savings in specific energy consumption can be achieved with vertical roller mills. Specific energy consumption depends on the grindability of the raw coal and the coal meal fineness required. A dynamic separator that ensures high separation efficiency also helps to reduce specific energy use.

The coal is grinded into pulverized coal in the coal ball mill mainly by means of three ways press strike and grind among them the first way is the most energysaving and the last one most energyconsuming during the milling process all kinds of coal mills,Steel Ball Cylinder Coal Mill.
In view of the above, the coal mill was secured by explosion suppression and decoupling systems a total of 6 HRD cylinders. Five of them were mounted on a coal mill and one on a dust duct transporting dust from the mill to the filter cutting off the explosion.
Pulverizers 101 Part I Every coal pulverizer is designed with a particular fuel grinding capacity or throughput at a certain Hardgrove grindability index HGI, based on a defined raw coal size

Coal mills variable loading hydraulic system is an important part of the coal mill, it consists of high pressure pump stations, oil lines, loading cylinders, accumulators and other components. The hydraulic system provide milling pressure varies with load of the grinding roller, the milling force is achieve by the proportional relief valve according to the changing load command signals to
Up to the mid1990s, coal pulverizing mills were generally equipped with classical metal cylinders with hydraulically actuated rams. The lifetime of the metal cylinders, however, proved unsatisfactory in the working conditions coal dust settled and caked onto seals and piston rods, having the effect of emery paper.
