Tank mill ball mill

The most important equipment in the preparation of aerated concrete raw materials is the ball mill, which is used for grinding lime, gypsum, sand, slag and other materials. Only after the materials have been ground and reached the required fineness can they be fully mixed and interacted to make the product reach strength. Grinding is an important process in the production of aerated concrete. The grinding process consumes a lot of power. Ball mills generally have the motor capacity in aerated concrete plants. largest device. It is composed of a horizontal hollow shaft for incoming and outgoing materials and a grinding head. The simplified version is a long cylindrical cylinder with a grinding body inside. The cylinder is made of steel plate and has a steel lining plate and a simplified fixed grinding body. The grinding body is generally a steel ball and has different diameters. And a certain proportion of the grinding body is loaded into the barrel. Steel segments can also be used to select according to the particle size of the grinding material. The material is loaded into the barrel from the hollow shaft at the feed end of the mill. When the ball mill rotates, the grinding body is driven by friction due to inertia and centrifugal force. The nearby cylinder lining plate is carried away by the cylinder. When it is brought to a certain height, it is thrown down due to its own gravity. The falling grinding body crushes the materials in the cylinder like a projectile.
.>Materials enter the first chamber of the mill evenly and spirally from the feeding device through the feeding hollow shaft. There are stepped linings or corrugated linings in the first chamber. Steel balls of different specifications are installed inside. The rotation of the cylinder generates centrifugal force to bring the steel balls. After reaching a certain height, it will fall and have a heavy impact and grinding effect on the material. After the material reaches coarse grinding in the first chamber, it enters the second chamber through the single-layer partition board. This chamber is equipped with a flat liner and has steel balls inside to further grind the material. The powdery material is discharged through the discharge grate plate to complete the grinding operation.
.>During the rotation of the cylinder, the grinding body also slips. During the sliding process, the material is given a grinding effect. In order to effectively utilize the grinding effect, when the material has a large particle size, the grinding body cylinder is generally ground to a fine size of 20 mesh. The body is divided into two sections by a partition plate, which becomes a double warehouse. When the material enters the first warehouse, it is crushed by the steel ball. When the material enters the second warehouse, the steel end grinds the material. The qualified material is discharged from the hollow shaft at the discharge end to the inlet. When grinding materials with small particle size, such as sand, No. 2 slag, coarse fly ash, the grinding volume of the mill barrel can be turned into a single barrel without partitions, or steel sections can be used.
