The_Component_Parts_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. ' Journal assembly - forged steel shaft supports a steel journal housing on carrying rings or roller bearings. ' Roll - cast and machined wear resistant steel roll is fastened to the tapered lower housing of the journal. ' Drive gears - cut steel bevel and pinion operate in a integral or independent housing. ' Base - heavy cast iron mill base is machined to provide an airtight fit for the return air housing, gear housing and mill bottom. ' Vertical shaft - cold rolled finished steel vertical shaft is engineered to support all moving parts. ' Mill bottom - cast iron mill bottom with replaceable liners fits into a machined recess in the base. ' Spider - ductile iron or steel plate is keyed to the main vertical shaft. ' Plow support - ductile iron plow support is bolted to the spider assembly ' Integral gear housing - cast iron gear housing contains the lower thrust bearings for the vertical shaft and the bearings for the horizontal shaft. ' Independent reducer - steel housing contains high efficiency gearing designed for maximum flexibility and extended service life.
