1406. Holman, J. H., and Holman, J. M. Jan. 18. Disk mills for wetgrinding. The material is ground between the vertical edges m of the perforated non - rotating mullers l and the renewable ring i at the side of the grinding-pan a, as well as between the horizontal surfaces n of the mullers and the perforated shoes j forming the bed of the pan. The driving-arms p of the mullers are carried by an adjustable sleeve q on the vertical driving-shaft c, the holes t1 in the lugs s through which the securing-pins t pass being elongated to allow the mullers to move outwards under centrifugal action. The pulp is introduced through passages at the periphery of the pan, and the ground material passes through perforations in the central hollow cone g, and through the opening e to the discharge spout h. The level at which the discharge takes place is regulated by plugging up some of the perforations in the cone g. A sleeve w prevents the water &c. from coming into contact with the shaft c. According to the Provisional Specification, the circumferential surfaces of the mullers may be formed with teeth.
