What are the different types of ball mill and how to select ball mills? General Mining Machinery is going to answer the questions for you.

First, ball mill kinds in market

One kind ball mill is from manufacturers direct sales. This kind ball mill manufactures has their own production base and R&D team, and as mass production, this kind ball mill always has relatively higher cost/performance ratio with low cost and reasonable quote. Zhengzhou General Mining Machinery Co., Ltd. is such kind of ball mill manufacture which has been specialized in ball mill production for decades years and it can provide customer satisfied machine quality and after-sale system; the other kind ball mill comes from agencies. They usually bought ball mills from one or more manufactures and in order to profit, they always raise price so this kind of ball mill always has a higher price. Besides, there also are some ordinary ball mill manufactures and traditional workshops whose price might low but their quality and after sales can not be guaranteed.

Second, key factors of ball mill selection

Enough capacity: selected ball mill should be able to complete required capacity meanwhile achieve the demanded particle size.

Higher capacity than designed capacity: ball mill design should take ore hardness and fineness changes into account because deeper ores usually get harder and finer, so selected ball mill should adopt to this condition and guarantee smooth initial stage production.

Do milling experiment: especially large concentration plants should select and enlarge the ratio according to testing data.

Select large equipment: large equipments will reduce the weight and area occupation of the whole equipment with fewer production systems, operators and assistant systems, resulting to low investment and production cost. But larger equipment requests high for operators.

Select equipment with high operation rate: in principle, equipment with high operation rate should be selected to reduce inspection time and downtime.
