Ball mill - grinding device

A laboratory ball mill for wet and dry grinding of various samples of materials is used in conditions of either small production or a special laboratory. This equipment is used to prepare small batches of material, as well as to simulate the grinding processes of raw materials. It is very important to pay due attention to the moment, which emphasizes what is absolutely necessary, so that the hardness of the material being ground does not exceed the hardness of the grinding walls and the body of the grinding drum.

Technical Specifications of Ball Mill

The laboratory ball mill, like all equipment, has its own technical characteristics. They are described in the technical passport to her. Some examples of the most important can be given. For example, a ball mill allows you to simultaneously dissolve the material in an aggressive or flammable liquid and grind it. In this case, this equipment should be equipped with an explosion-proof engine, oil and gas resistant or acid-resistant gaskets, and the pulley and belt drive rollers should be made of aluminum alloy. Ball mill must always be protected from various kinds of explosions.

Principle of operation

Laboratory ball mill is made in only two versions:

1. desktop version;

2. outdoor option.

This device consists of a frame welded from a steel profile and painted with powder paint, on which two shafts must be installed. The first shaft is rigidly fixed to the mill frame and is connected by a V-belt to the engine. The second shaft should rotate easily in the bearings.

Depending on the size of the diameter of the grinding drum, you need to adjust the distance between the shafts. The ball mill works like filling with grinding bodies, crushed products or drum fluid. After that, the drum is closed by a lid. The cover must be airtight and reliable. It also works on the principle of large industrial wet or dry mills, using in its use the abrasion-impact effect of the dying walls and the drum body on the material.

Mill completeness

Laboratory mills are equipped, depending on the customer’s choice, with steel, porcelain or stainless steel grinding drums of various volumes. The frequency converter is installed to change the speed of rotation of the drum. Without it, the device adjusts to the average number of revolutions per minute. The mill has a standard set, which includes a frequency converter, drive, grinding drum and a sufficient number of grinding bodies. Laboratory ball mills begin their work thanks to electric motors that protect against overheating and overload.
