How to Make a Ball Mill: 12 Steps (with Pictures) wikiHow

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Inferential measurement of SAG mill parameters III ... ScienceDirect

Control objectives and strategies could be also formulated incorporating this measurement. For instance, the recirculating load measurement (RCL) could be utilised as feedback for control of SAG mill water addition or primary cyclone underflow split to the ball mill (PC split). Step 2: SAG mill rock charge

Grinding Bulletin #4 Metcom

The first step is to recognize the relationship between the ball mill circuit circulating load ratio (CLR) and the overall circuit capacity or efficiency. (See Bulletin No. 1 on how to calculate the CLR for your circuit.) See Figure 1. With a CLR of 160% the circuit is close to times more productive (efficient) than open circuit (0% CLR).

Grinding Classification Circuits 911 Metallurgist

An iron ore company milled ore at the rate of 150 t/h in a ball mill in closed circuit with a classifier. The underflow (course) stream was recirculated to the mill till a steady value was obtained in the cyclone overflow stream. The specific gravities of each stream were measured as: a) Mill discharge stream to classifier = SG(md)
