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.
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 because of limitations on the drying capacity of the mill. The roller mill, when equipped with a variable speed mill drive, can be used in applications requiring adjustable capacity. This allows the user to match product rate with downstream process requirements, thereby reducing the operating and maintenance problems associated with frequent starts.
At the present, Hongxing mining machinery has set up three state level machinery research institutes, and we also produce various kinds of raymond grinder，coal grinding mill and free service for assembling various kinds of production line.
