Zenith designs and manufactures a comprehensive line of ball mills and entire grinding systems for mining, industrial minerals industry, coal and cement, including classifiers and related accessories for both wet and dry grinding systems. We offer a complete spectrum of engineering services, including testing, process design, installation, commissioning, start-up, and continuous lifetime product support services.

Features

1. Cast side plates bolted to a rolled-steel drum with integrated manhole;

2. Drive via ring and pinion gear with automatically controlled tooth lubrication, primary gearing with couplings and high-performance gearbox;

3. Bearing unit: journal bearing designed as a friction bearing with closed loop oil recirculating lubrication with temperature control;

4. Product discharge via adjustable slots located around the periphery of the drum. Two-piece discharge housing with top venting connection with inspection cover.

Application

A ball mill grinds ores and other materials to a typical product size of 35 mesh or finer.

The feed to a ball mill is prepared by:

1. Single or multistage crushing and screening;

2. Crushing, screening, and/or rod milling;

3. Primary crushing and autogenous/semi-autogenous grinding.

Normal feed sizes:

1. 80% passing 1/4" (6 mm or finer) for hard ores;

2. 80% passing 1" (25 mm or finer) for softer ores.

The length to diameter ratio of cylindrical mills range from 1 to 1 through 3 to 1. When the L/D ratio is 2 to 1 or greater, we refer to the mill as a tube mill.
