— Springs exert necessary pressure on rolls for grinding. Hot air through the mill besides removing coal moisture, picks up the lighter particles and takes them through the classifier and drop down the higher size particles for further grinding. Fine coal air mixture leaves the mill and enters the fuel piping system.
Whether grinding raw coal, clinker, cement and/or slag, we have a VRM solution to suit your grinding needs. What's more, our online condition monitoring services enable you to adopt a proactive maintenance strategy for your OK™ and ATOX® mills that eliminates unexpected downtime and ensures continuous high performance.
— The rubbing and ploughing contribute little to material removal, while cutting or chip formation is the desirable grinding function that removes materials. All these functions would create heat that elevates grinding temperature. Often, the grinding heat generation or temperature elevation can also be a measure of the grinding efficiency.

— As one of the three major forces of coal mills, the grinding force exerts a significant impact on the working process of coal mills and parameters like mill current and outlet temperature.
Coal is crushed to desired fineness between spheres or cylindrical rollers. After that, air from the boiler is heated to around 330°C (650°F). The raw coal is then fed into the pulverizer where it is ground into fine coal particles. What are the Advantages of Pulverized Coal? Pulverized coal produces a larger amount of heat than traditional coal.
