Description

Intelligent ball placing equipment of ball mill and use method thereof
Technical Field
The invention relates to the field of mining machinery equipment, in particular to intelligent ball placing equipment of a ball mill and a using method thereof.
Background
The ball mill is a key device for crushing materials after the materials are crushed. This type of mill is one in which a number of steel balls are inserted into its cylinder as grinding media. It is widely used in cement, silicate products, novel building materials, refractory materials, chemical fertilizers, mineral processing of black and nonferrous metals, glass ceramics and other production industries, and carries out dry or wet grinding on various ores and other grindability materials. The ball mill is suitable for grinding various ores and other materials, is widely used in the industries of mineral separation, building materials, chemical industry and the like, and can be divided into dry type and wet type ore grinding modes. According to different ore discharging modes, the two types of the grid type and the overflow type can be realized.
The ball mill consists of horizontal cylinder, hollow feeding and discharging shaft, grinding head, etc. the cylinder is long cylinder with grinding body inside, the cylinder is made of steel plate, steel lining board is fixed to the cylinder, and the grinding body is steel ball and may be steel segment. The material is selected according to the granularity of the ground material, the material is filled into the cylinder body by the hollow shaft at the feeding end of the ball mill, when the ball mill cylinder body rotates, the grinding body is attached to the cylinder liner plate and taken away by the cylinder body under the action of inertia and centrifugal force, and when the ball mill cylinder body is taken to a certain height, the ground material in the cylinder body is thrown down under the action of gravity of the grinding body, and the fallen grinding body breaks up the material in the cylinder body like a projectile.
The steel balls in the ball mill are necessary consumables in the ball mill, the sizes of the steel balls can be divided into a large ball, a medium ball and a small ball, the diameters of the large ball are divided into 120mm and 100mm, the diameters of the medium ball are 80mm, and the diameters of the small ball are divided into 60mm and 40 mm. Because of the reasonable friction generated between the steel balls and the steel balls, between the steel balls and the ore and between the steel balls and the lining plate of the ball mill during normal operation of the ball mill, the abrasion is increased, so that the big ball is ground into the middle ball and the middle ball is ground into the small ball. In order to maximize the productivity of the ball mill, steel balls accounting for 30-40% of the volume of the ball mill need to be added. Therefore, in the use process of the ball mill, steel balls are required to be continuously added into the ball mill, and the new steel balls are added from the feed inlet in the conventional technology, however, as the sealing mode of the feed inlet of the ball mill is a packing type seal, the sealing effect of the packing type seal is poor, the leakage phenomenon of material slurry (such as limestone slurry) can often occur, and the leaked slurry can enter a bearing supported below a cylinder body, so that the normal operation of the ball mill is seriously influenced, and the desulfurization effect of a generator set can also be influenced.

The ball mill provided by the invention does not need to stop the operation of the ball mill and does not need to disassemble the manhole when the steel balls are added, so that the problem that the risk of overhead operation is increased due to the need of frequently disassembling the manhole is solved, and the steel balls can be added into the cylinder of the ball mill under the condition that the ball mill is operated, and the ball mill is easy, convenient, safe and practical to operate.
However, in this patent, in order to prevent the steel ball feeding pipe from colliding with the steel ball in the cylinder, the steel ball feeding pipe is extended to the edge of the discharge hole of the cylinder, so that the steel balls are unevenly distributed in the cylinder, especially, since the steel balls located on the feeding side of the cylinder have the largest effect on grinding mineral aggregates, the steel balls are mainly transmitted to the discharging side, so that the condition that the mineral aggregates are not thoroughly ground can occur, and the product quality is finally affected.
