The Working Capacity of a Roller Mill

Most naturally occurring non-metallic minerals and many manufactured products contain a certain amount of free moisture. Raymond’s technique combines drying and pulverizing in the roller mill which may eliminate independent drying equipment thus reducing capital investment, processing time and handling. Heated air or hot waste gas is delivered to the mill return air housing and introduced through air ports to the grinding zone in the mill. The air turbulence and particle size produced during the grinding process are ideal for almost instantaneous evaporation of moisture. Feed moisture is normally limited to what can be reliably fed into the mill. Typical product moisture is 0.1 to 0.5% by weight.Raymond pulverizing and classification equipment has been setting the standards in size reduction since 1885, serving many types of mineral processing industries. Our portfolio includes not only the Raymond Roller Mill but the Raymond Imp Mill, Raymond Bowl Mill, Raymond Vertical Mill, Raymond Ultra Fine Mill and others. Raymond Roller Mills: More than 2,000 roller mills have been supplied since the first mills were designed in the late 1800’s. These early machines were the forerunner of the heavy-duty, rugged ring-roll mill manufactured today. The roller mill provides the needed flexibility to economically and efficiently process a wide variety of materials.Scientific management, advanced processing technology and innovative manufacturing theory make Hongixng become the exporting base of raymond mill, raymond grinder and famous grinding equipment in China. What Hongxing has done is for the clients and we believe that quality is the best way to develop market.Major factors affecting the capacity of a roller mill include desired fineness, grindability and initial moisture. The capacity of the mill decreases when product fineness increases. The harder a material is to grind, the lower the capacity of the mill. High initial moisture may also decrease mill capacity…
