| Question: | ball mill problem |
| Detail: | what is the effect of lining wearing on mill motor power,grinding media motion,flow of material and grindability? |
| Reply: | Liner wear will almost always reduce mill performance. In case of lifting liners the lift will be deminished, in case of classifying liners the media classification will be less effective. It really depends upon the mill system: Wet or dry? SAG? Two-compartment? Type of grinding media? Mill motor power goes down, grindability (or better: specific power consumption)goes up. |

| Question: | Give suggestions |
| Detail: | I wish to buy industrial milling machine from your compny and i wish to be milling bentonite poweder,ceramic frits/glaze, Could you give some suggestions ? |
| Reply: | We are one of the largest manufactures of crushers and industrial mills in our country and have handled with various kinds of the products for about 21 years. Our mills are suitable for grinding the bentonite, ceramic frit, etc, so we would like to know more details, like the feeding size, output size and capacity you need, with which we can recommend you the suitable model. |

| Question: | Output of Ball Mill |
| Detail: | Dear sir, i am currently a final year student in University of Science Malaysia. As taking my design course, i was requested to design a small metal powder production plant, with production rate 20kg/hr and final product; 10micron metal powder. i would like to install two series ball milling in my plant, by wonder how effecient is the ball mill is, is there any calculation to determine the product of the ball mill, i.e a coarse particle input, how fine is the output particle is. Hope Sir can enlighten me. Thanks. |
| Reply: | Dear Maresa Input ore > black box efficiency > output.But to put numbers to the efficiency factor is not so easy. Different products react differently. Several factors influence the efficiency of ball mill grinding. The pulp density within the mill should be as high as possible consistent with ease of flow through the mill. It is essential that the balls are coated with a layer of pulp. Too dilute a pulp increases metal to metal contact - which increased steel wear and reduces efficiency. Most do a bench test rather than relying on some theoretical model. |
