Contactdynamic separator, the ATOX coal mill will grind any type of coal to the required fineness at the highest efficiency. When provided with a variable speed mill motor, the ATOX will also grind petcoke and anthracite down to a fineness below 5% +90 μm. Furthermore, it is designed to stand up to rugged outdoor conditions. Built-in economy
ContactSince 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 coal-fired 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.
ContactIn coal milling for power stations, a ‘closed-loop’ process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.
