The specific introduction of raymond 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. Each roller mill system is custom designed to achieve the best solution for your processing application. The mill feeder, roller mill, classifier, fan, cyclone, dust collection and other system components are selected to meet the requirements and characteristics of the material processed.
The roller mills is an air swept vertical ring-roll mill with an integral classification system. A vertical shaft rotates a “spider” assembly of arms from which are suspended free swinging journal assemblies with rolls attached. As the unit turns, centrifugal force drives the rolls against the inner surface of the vertical grinding ring. Plows rotating with the assembly, lift feed material from the mill bottom and direct it between the rolls and the grinding ring where it is pulverized. Air enters from below the grinding rings and flows upward, carrying fines to the classifying section. The classifier sizes the pulverized material and returns oversized particles to
