Different specification steel balls are installed on the scale board in the ball mill, when the barrel body rotates and produces centrifugal force,at this time, the steel ball is carried to some height and falls to make the material grinding and striking. The speed of rotation is the greatest important factor in the operation of the ball mill.
Normally to reduce the big ore lumps to small particles, two to three stages crushing is required. Prominer has the ability to supply complete crushing and screening system, including various crusher, screen, belt conveyor, iron remover, etc. For minerals with different properties and hardness, we can recommend suitable crusher accordingly ...
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
Steel bars pound the metal by tumbling inside the plant media and the poles tumble and turn in generally parallel arrangements mimicking a progression of move crushers. Since a bar process doesn't course it can be worked at a lower fringe speed than a ball process and since there is less void space in a pole process than a ball process there ...

From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pig iron is the most energy intensive process for steel production at roughly 13.5 × 10 9 joules per ton (1000 Kg) of pig iron produced. The basic oxygen furnace is the second most energy intensive process at 11 × 10 9 joules per ton or steel produced. The Electric arc furnace has significantly less …
It comprises of a small Lead Melting Furnace, operating in line with a hemispherical ball-casting machine, which feeds the balls to the ball mill .In the ball mill, Lead is converted to Lead Sub Oxide in an exothermic process, in conditions of a maintained temperature range of 135-145 degrees centigrade and constant airflow.
The process involves the following stages: 1. Incoming inspection of preform.

Steel balls with various sizes were placed into the mill. 369.3g of salt was then added into the mill. Milling process was carried out for 10-20 minutes with suitable speed of rotation. After the milling process was completed, salt powder was weighed. The salt powder obtained was sieved by using sieve analysis (sieve nest).
