Profile: Whitfield and Son Limited is a distributor of industrial materials. Our materials include Plaster of Paris, grinding media, alumina, mill linings, elastomers & resins, barium sulphate, and refractory materials. The properties of these extremely hard linings are the same as high density alumina grinding media, and they are used to produce high-value products. Linings are tailor-made to fit a particular mill, and it is therefore essential that accurate drawings of the internal mill shell are provided, so that these linings can be fabricated with minimum waste.
