Mechanical Knowledge Base: "Ball Mill"

The ball mill is the key equipment for crushing the material after it has been broken. It is widely used in cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal beneficiation and glass ceramics, and other industries, the dry or wet grinding of a variety of ores and other abrasive materials. The ball mill is suitable for grinding a variety of ores and other materials and is widely used in mineral processing, building materials and chemical industries. It can be divided into dry and wet grinding methods. According to different ways of ore discharge, it can be divided into grid type and overflow type.

Ball grinding mill

The ball mill is the key equipment for crushing the material after it has been broken.

The ball mill is one of the high-fine grinding machines widely used in industrial production.

There are many types, such as hand ball mills, horizontal ball mills, ball mill bushes, energy-saving ball mills, overflow ball mills, ceramic ball mills, and lattice ball mills.

The ball mill is suitable for grinding a variety of ores and other materials and is widely used in mineral processing, building materials and chemical industries. It can be divided into dry and wet grinding methods. According to different ways of ore discharge, it can be divided into grid type and overflow type.

working principle

Ball mill The most important equipment in the preparation of raw materials for aerated concrete is a ball mill. It is used for the grinding of lime, gypsum, sand, slag and other materials. The materials can only be fully mixed and interacted after grinding to achieve fineness, so that the products can reach strength. Grinding is an important procedure in the production of aerated concrete. The grinding process consumes large amounts of power. The ball mill is generally aerated concrete. Plant with the largest motor capacity in the factory.

The ball mill consists of horizontal Simplified, in-out material hollow shafts and grinding heads. It is simplified as a long cylinder. The cylinder is equipped with a grinding body. The barrel is made of steel plate. It has a steel lining plate and Simplified fixing. The grinding body is usually steel. The ball is made into balls and filled into the cylinder according to different diameters and certain proportions. The grinding body can also be made of steel segments.

According to the granularity of the grinding material to be selected, the material is loaded into the barrel body by the hollow shaft of the feed end of the mill. When the ball mill is simplified and rotated, the grinding body acts due to the inertia and centrifugal force, and the frictional force acts on the barrel lining nearby. It is carried away by the tube, and when it is brought to a certain height, it is thrown off by its own gravity, and the falling grinding body smashes the material inside the barrel like a projectile.

The material is fed into the first chamber of the mill through the feeding device through the hollow shaft of the feed material. The chamber has a stepped liner or a corrugated liner, which contains steel balls of different specifications. The cylinder rotates to generate centrifugal force to bring the steel ball to a certain height. After falling, it will produce heavy blow and grinding effect on the material. After the raw material reaches the rough grinding in the first position, it enters the second position via a single-layered partition board. The leveling insert has a flat lining plate with steel balls inside and the material is further ground. The powder is discharged through the discharge sampan plate to complete the grinding operation.

In the process of rotating the barrel, the grinding body also has a slip phenomenon. In the sliding process, the material is subjected to grinding. In order to effectively use the grinding effect, the grinding body is generally used when the material grain size is generally reduced to 20 mesh. Separated into two sections by the partition board, that is, it becomes a double warehouse. When the material enters the first warehouse, it is broken by the steel ball. When the material enters the second warehouse, the steel end grinds the material, and the qualified material is hollowed out from the outlet end. Shaft discharge, when the small feed material for grinding, such as sand No. 2 slag, coarse fly ash, mill barrel can be set without a partition, a single silo barrel grinding, grinding volume can also be used for steel section .

This machine is a horizontal cylindrical rotating device, external gear drive, two positions, lattice type ball mill. The material is fed into the first chamber of the mill through the feeding device through the hollow shaft of the feed material. The chamber has a stepped liner or a corrugated liner, which contains steel balls of different specifications. The cylinder rotates to generate centrifugal force to bring the steel ball to a certain height. After falling, it will produce heavy blow and grinding effect on the material.
