Intermittent Ball Mill--Advanced Technology

Functions of Intermittent Ball Mill:
Intermittent Ball Mill is an essential recrushing equipment. It is widely used in cement, silicate, new construction material, refractory materials, fertilizer, black and non-ferrous metal ore dressing, glass ceramic industry, etc., and performs dry or wet grinding on all kinds of ores adn other grindable materials.
Classification of Intermittent Ball Mill:
1)Medium of the ball mill is metallic ball(steel ball or cast iron ball). Medium of the rod ball mill is steel bar. Gravel grinding machine's medium is grinding medium.
2)According to the discharging pattern, the ball mill can be divided into overflow type grinding machine. It is through the row of the hollow shaft neck that ore pulp runs out of the spill freely.
3)According to the shape of the ball mill cylinder body, the ball mill can be classified into:
a) Short-tube mill: L/D≤1.0—1.5(L is the barrel length and D is the diameter of the cylinder.)
b) Long-tube mill: L/D≥1.5
c) Tube mill：L/D=5—6. Its interior is divided into several rooms, thus called multi-room grinding machine, commonly used in cement industry.
4)Cone mill: Due to the low rate, utilization rate is not sufficient, abrasive efficiency is low, our country has stopped manufacturing this type of ball mill.
Working Principle of Intermittent Ball Mill:
Through material hollow shaft spiral the material is sent to the first mill chamber, in which there are ladder liner or corrugated linings, with steel balls of different specifications in it. When cylinder rotating, centrifugal force will produce steel ball fall down from a certain height, thus impacting and grinding the materials. After coarse grinding in the first chamber, materials enter into the second chamber through a single diaphragm. In this warehouse with flat lining board and steel balls in it, materials are further grinded.
