China Supplier Latest Technology Small Gold Mining Ball Mill for Rock Gold Ore Processing

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are made of high-chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the mill due to centrifugal action.

1). Wide usage, simple structure, convenient maintenance;

2). Big capacity, continuous working;

3).Body liners and grinding medium could be made of various of materials, good corrosion resistance;

4). Easy installation, adjustment, and operation.

Mill could be sorted as following:

1).As per the grinding media: ball mill, rod mill and AG Mill (without grinding media).

2).As per material discharging mode: wet grid mill, dry grid mill & overflow mill.

3).As per driving mode: side & central driving. The former is more popular now.

The machine is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control).

The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance.

1).The diameter of the steel ball is mainly based on the hardness of the materials.
If the ball mill has large diameter, it will has huge impact, so we can choose the smaller steel ball.
2). The small ball mill uses double storehouse clapboard should have smaller steel ball compared with the single one.
3). Generally, we keep to the level four principle, there are little large and small steel balls, that is, we mainly use middle size as the grinding medium.

In order to give you a responsible quotation, you can inform us the following information
1).  What's the material you are going to deal with?
2).  What's the granularity of the material?
3).  What's the granularity of the final products are you going to achieve?
4).  What's the producing capacity you are going to achieve? If your required capacity is mini and the gold grade is low,a wet pan mill is recommend which is economic.
