How Ball Mill works - Efficient machine for grinding various materials into powder

HAMAC Ball Mill is crucial equipment for grinding after materials are crushed. It is an efficient machine for grinding various materials into powder.

Ball Millis widely applied in cement industry, chemical industry, new building materials, fire-resistant materials, fertilizer, porcelain and glass industry etc. It has two ways of grinding: dry process and wet process.

The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material.

Ball Mill Principle

HAMAC ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.

Ball Mills Application

This Ball Mill, a horizontal type and tubular running, has two warehouses. It runs along the outside gear. Materials spirally and evenly enter the first warehouse along the input hollow axis by input devices. In the warehouse, there is a ladder scale board or ripple scale board. Steel balls of different specifications are installed in the scale board. When the barrel body rotates, centrifugal force is produced. At the same time, the steel balls are carried to some height and then fall to grind and strike the material. After being grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding. In the end, the powder is discharges by output material board.

Ball Mill Maintenance

Ball Mill repair and maintenance are crucial for assuring manufacture efficiency. If not maintained properly, HAMAC ball mill run-time will be reduced causing substantial economic losses.

1. The operators must be qualified with the required technical knowledge, receive technical training and fully understand the operating principle, performance a regulations of the ball mill.

2. The operators should follow the operate principle and lubricate the requirement parts marked in lubrication picture. Untreated waste oil may not be used and keep lubrication points clean.

3. Pay attention to check the temperature of bearing not to exceed 60 ℃ and make sure every bolt not loose, no abnormal sound, uniform mining feed, steady water feed, normal current, voltage of motor.

4. To keep surroundings clean where the ball mill run. Every party should be clean unless it's running.
