Portable Small Laboratory Grinding Ball Mill, Mini Rod Mill

Product Description

Portable small laboratory grinding ball mill,mini rod mill for grinding lead ore 

QM series new type horizontal Mini Rod Mill features: reasonable structure design, convenient operation, as well as strong adaptability. This  can be used for material superfine grinding and mixing in chemical, abrasive, ceramics, medicine, food and other industries.

As per customer's different requirements, there are Mini Rod Mill with jacket or without jacket. (The ball mill with jacket can automatically discharge and separate minerals from steel balls, as well as dust proof.) The cylinder body can be made of ordinary steel, high quality stainless steel or other materials. It also can be lined with ceramics, polyurethane or PP materials.

Structure and Working Principle of Mini Rod Mill

 

This Mini Rod Mill is composed of motor, reducer, cylinder body, bearing seat, belt pulley, and control box etc. The cylinder body is filled with a number of grinding medium (zirconia balls, polyurethane balls, or bearing steel balls etc). The grinding medium and minerals are lifted up to a certain height by the rotation force of cylinder body, and then detach the cylinder wall and drop down following a parabola by the force of gravity. The minerals are crushed and mixed by friction and shear generated by rolling and sliding of grinding medium's impacting and grinding.

Selection of grinding medium and filling amount of material for Small Wet Grinding Mill

1. Selection of grinding medium
Basic principle for selecting: the density and hardness of grinding medium for Laboratory Ball Mill shall be higher then that of the mineral, the medium shall not be polluted to the mineral and can be easily separated from the minerals. There are various kinds of grinding medium available, such as steel ball, porcelain ball, corundum ball, zirconia ball, and sintered carbide ball etc.

2. The filling amount of grinding medium and minerals depends on the specific gravity of the medium and the minerals, as well as the cylinder volume of the Laboratory Ball Mill

3. The total filling amount of grinding medium and minerals shall be no more than 50% effective volume of the cylinder so that the grinding efficiency would be the best.

Features of Mini Rod Mill

Simple and convenient operation, reliable performance, easy cleaning, and strong adaptability;
The dry small lab ball mill can be used for both dry and wet grinding for processing materials of various hardness. It also can be used for both coarse and fine grinding and material mixture;
Due to the closed operation, there would be no dust. For facilitating the recovery of ultrafine powder, it uses the protective cover discharge for dry grinding that ≥50L and the minerals and steel ball automatically separate so that the discharge will be quite convenient. As a result, the recovery rate of the grinded materials can be up to 100% without any pollution which meets with the GMP standard;
The inner liner of the cylinder body can be made of alloy steel, stainless steel, high wear-resistant polyurethane, alumina ceramics, or zirconia ceramic as per customer's requirement. Meanwhile, it can be produced with the jacketed type as per the special request, which can reach the effect of heating or cooling.
