Product Design Features of Wet Type Rod Mill

Wet type rod mill is one of the types of rod mill, which can be widely used in the processing of quartz sand, dolomite and monazite, ore-dressing of non-ferrous metals, ferrous metals and non-metal, the first-stage ore milling of artificial stone sand, dressing plant, chemical plant and power sector, and the grinding of the chemical industry, building materials and other materials.

Product Design Features of Wet Type Rod Mill:

1. Rod grinding mills are equipped with a replaceable liner in the discharge trunnion and a discharge spout attached to the trunnion so that the pulp or dry product is discharged away from the trunnion bearing. A single surface trommel screen or a splitter for distributing the pulp to two or more launders is often attached to the discharge trunnion.

2. New feed is introduced through a feed chute or drum feeder attached to one of the hollow trunnions. The product is discharged through a suitable opening in the opposite trunnion or through ports in the periphery of the rod grinding machine shell. The trunnion, end peripheral and center peripheral discharge arrangements are illustrated on the opposite page.

3. High carbon steel rods varying from 1 1/2” to 4 1/2” in diameter, as required for the specific grinding application, extend the full working length of the cylindrical mill section. The optimum rod charge typically occupies 35% of the internal shell volume for most grinding applications.

4. Rod grinder operating with a peripheral discharge are supplied with stationary plate steel housing to confine the material and discharge it through a bottom opening. Dry grinding mills are arranged so that dust can be vented into a dust collecting system.

5. The conical heads attached to the ends of the cylindrical shell section are provided with hollow trunnions of large diameter and narrow width for supporting the shell in suitable bearings.

6. Grinding rod mills are built in sizes from 3’ to 14’ shell diameter with shell...
