Abstract
Pebble mill linings used in the ceramic industries consist chiefly of flint, quartzite, and porcelain blocks. Rubber linings have had considerable attention recently. The advantages and disadvantages of each type are discussed. Data are given showing relative costs at the Champion Porcelain Company of Belgian flint, “sillimanite” spark plug porcelain, and one-piece rubber linings. Of the first two, the porcelain showed the lowest cost per year of service. The test of the rubber lining is not complete, but its high initial cost practically eliminates it on that basis. For special purposes the additional cost of the rubber lining might be justified.
