Abstract
A discharge assembly mounts inside a grinding mill on a mill shell at a discharge end of the mill and rotates about a longitudinal axis of the mill. The discharge assembly includes a plurality of ring sections forming an assembly covering the mill shell at the discharge end. Each ring section has an outer surface supported on the mill shell and inner surfaces forming a radially extending discharge passageway. Each ring section connects to an adjacent ring section to form a lapped joint therebetween and additional radially extending discharge passageways. Each lapped joint seals the mill shell from the discharge passageway to prevent discharged material contained therein from wearing the mill shell.
Claims14
A discharge assembly for use in a mill rotating about a longitudinal axis, the discharge assembly being mounted inside the mill on a mill shell at a discharge end of the mill, the discharge assembly comprising:
- a first plurality of ring sections forming a ring assembly covering the mill shell at the discharge end, wherein each ring section has a first end and a second end with a first surface supported on the mill shell and a second surface forming a radially extending discharge passageway, and wherein each ring section connects to an adjacent ring section to form a lapped joint therebetween from the first end to the second end, the lapped joint having a layer of compressible material for sealing the discharge passageway from the mill shell.
A discharge assembly for use in a mill rotating about a longitudinal axis, the discharge assembly mounted inside the mill on a mill shell at a discharge end of the mill, the discharge assembly comprising:
- a plurality of outer ring sections forming an outer ring assembly covering the mill shell at the discharge end, wherein each outer ring section has a first end and a second end with an outer surface supported on the mill shell and inner surfaces forming a radially extending outer discharge passageway, and wherein each outer ring section connects to an adjacent outer ring section to form a lapped joint therebetween from the first end to the second end, the lapped joint having a layer of compressible material for sealing the mill shell from the outer discharge passageway;
- and
- a plurality of inner ring sections forming an inner ring assembly covering the mill shell at the discharge end, wherein each inner ring section has a first end and a second end with an outer surface supported on the mill shell and an inner surfaces forming a radially extending inner discharge passageway, and wherein each inner ring section connects to an adjacent inner ring section to form a lapped joint therebetween from the first end to the second end, the lapped joint having a layer of compressible material for sealing the mill shell from the inner discharge passageway, the inner ring formed radially inward toward the longitudinal axis from the outer ring with the inner discharge passageway communicating with the outer discharge passageway.
