Shenyang Sanland Mining Engineering Co., Ltd. makes mill feed and discharge ends, the parts that carry load between shell and inlet or outlet and keep the joint tight. Two freshly machined ends stand side by side in the works, turning marks still on faces, spigots and flanges, coated in anti-rust primer and waiting for their shell.

Each end is a cylindrical body with a flange and spigot: one side bolts to the shell face, the other mates with the trunnion and the feed or discharge chute. Spigot fit and squareness of face to axis decide how the joint closes; a poor fit leaks slurry, and squareness out of tolerance sets the shell swinging.

The body is rolled from heavy plate, welded and stress-relieved as a whole before finish machining. Set up vertically on a heavy vertical lathe, face, spigot and flange are turned in one clamping, so no error accumulates from re-setting. Flange holes are match-drilled to the developed drawing and spot-faced, so the joint loads evenly.

Work this size tests equipment and organisation as much as the operator. Heavy vertical lathes and floor borers here cover mill ends, shell flanges and gear blanks, and single pieces, small batches or full machine sets can all be scheduled from drawings. Rough machining, heat treatment, finish machining and inspection close inside the works.

An end machined to drawing goes straight onto the shell without site fitting. Shenyang Sanland Mining Engineering Co., Ltd. focuses on crushing, screening and grinding equipment, supporting mining and aggregate projects at home and abroad with complete machines and spare parts.
