Cone Discharge For Diaphragm Discharge Rotary Grinding Mill
US Patent:
4646980, Mar 3, 1987
Filed:
May 20, 1985
Appl. No.:
6/736426
Inventors:
Duane W. Player - Salt Lake City UT
Peter W. Leach - Fort Collins CO
Peter W. Leach - Fort Collins CO
Assignee:
Evans Products Company - Wilmington DE
International Classification:
B02C 1718
US Classification:
241179
Abstract:
A discharge cone casting for the discharge end of a rotary mill is disclosed which is integrally cast in a single component. The casting specifically consists of a generally flat base member adapted to conform to the discharge end of the mill and having converging sides, a top member having converging sides similar to those of the base member and disposed in overlying relation but also including a portion that extends beyond the base member and curving toward its plane, and an interconnecting web extending transversely between the base and top member to define a generally I-shaped cross section. Mounting bolt holes are formed through the upstanding web to enable the discharge cone casting to be bolted directly to the mill end as a single unit.
Roll Crusher
US Patent:
4232834, Nov 11, 1980
Filed:
Aug 13, 1979
Appl. No.:
6/065836
Inventors:
Duane W. Player - Salt Lake City UT
James A. Weil - Plymouth MN
James A. Weil - Plymouth MN
Assignee:
Minneapolis Electric Steel Castings Company - Minneapolis MN
International Classification:
B02C 430
US Classification:
241293
Abstract:
The disclosure is directed to an improved roll crusher comprising a central hub mounted on a rotatable shaft, a roll member carried by the hub in concentric relation thereto, and a pair of clamping rings for securing the components together. The roll member and hub have angular surfaces disposed in opposed relation to define a pair of annular, axially facing recesses having V-shaped sides. The clamping rings are constructed to fit into the recesses, each defining inner and outer circumferential surfaces which are angled to correspond to the angled surfaces of the hub and roll member. A plurality of equiangularly spaced bolts connect the clamping rings and hub, drawing the clamping rings toward each other to wedge the roll member radially outward relative to the hub. As a result, the roll member is fixed in a centered, balanced position relative to the hub. A plurality of lugs and lug receiving recesses cooperate to prevent relative rotation between the roll member and hub.
