Technical Field

The utility model belongs to the technical field of the ball mill, specifically be an automatic ball device that adds of ball mill.

Background

The ball mill is the key equipment for crushing the materials after the materials are crushed. It is widely used in the production industries of cement, silicate products, refractory materials, fertilizers, metal ore dressing, glass ceramics and the like to carry out dry or wet grinding on various ores and other grindable materials. The ball mill can be classified into a short-tube ball mill, a long-tube ball mill, a tube mill and a cone mill according to the shape of the tube body.

The ball mill is composed of horizontal cylinder, hollow feeding and discharging shaft and grinding head, the cylinder is long cylinder, the grinding body is installed in the cylinder, the cylinder is made of steel plate, and is fixed with the cylinder by steel lining plate, the grinding body is generally steel ball, and is loaded into the cylinder according to different diameters and a certain proportion.

The material is selected according to the granularity of the grinding material, the material is loaded into the barrel body from the hollow shaft at the feeding end of the ball mill, when the ball mill barrel body rotates, the grinding body is attached to the lining plate of the barrel body and taken away by the barrel body under the action of inertia and centrifugal force and friction force, when the grinding body is taken to a certain height, the grinding body is thrown off under the action of the gravity of the grinding body, and the falling grinding body breaks the material in the barrel body like a projectile body.

The materials are fed into the first bin of the mill by a feeding device through a hollow shaft, and the bin is internally provided with a stepped lining plate or a corrugated lining plate which is internally provided with steel balls of various specifications, and the steel balls are driven to fall down after being driven to a certain height by the centrifugal force generated by the rotation of a cylinder body, so that the materials are impacted and ground. After the material reaches rough grinding in the first bin, the material enters the second bin through the single-layer bin partition plate, the flat lining plate is inlaid in the bin, the steel ball is arranged in the bin, and the material is further ground. The powder is discharged through the discharging grate plate to finish the grinding operation. In the process of the rotation of the barrel, a grinding body also has a slipping phenomenon, the grinding body can grind materials in the slipping process, in order to effectively utilize the grinding effect, when general twenty-mesh grinding with larger material granularity is carried out, the barrel of the grinding body is divided into two sections by a compartment plate, so that a double bin is formed, the materials are crushed by steel balls when entering the first bin, the steel sections grind the materials when entering the second bin, the finely ground qualified materials are discharged from a hollow shaft at the discharge end, when the materials with small feeding particles are ground, such as sand second slag, coarse coal ash and the barrel of the grinding machine can be used as a single bin barrel mill without a partition plate.

Through the grinding process, the steel balls as the grinding bodies are worn and are continuously worn, and the worn steel balls in the prior art need to be intensively added into a ball mill bin at one time, so that the problems of low production efficiency, high product cost and incapability of full-load production of the ball mill are caused. In order to realize automation of production of modern enterprises and full-load production by utilizing equipment, a set of automatic steel ball adding device of the ball mill is designed, so that steel balls can be added into the ball mill at any time without shutdown in the running process of the ball mill, and the problem that the ball mill cannot be used for full-load production is solved.
