A high-efficiency ball mill with reinforcing ribs

Abstract

The invention relates to the field of ceramic machinery, in particular to an efficient ball grinding mill with reinforcing ribs. A cylinder body is of a two-layer tubular structure, the first layer is a cylinder body shell, the second layer is a preliminary screening and grinding mesh tube with screening holes, grinding balls are placed inside the cylinder body, a feed port of the cylinder body is connected to a cavity of the preliminary screening and grinding mesh tube, and a discharge port of the cylinder body is connected to a cavity between the inner surface of the cylinder body shell and the outer surface of the preliminary screening and grinding mesh tube; a lining plate is arranged inside the cylinder body shell, is formed by splicing a plurality of lining bricks and is cylindrical, the reinforcing ribs and the lining plate are arranged on the inner surface of the cylinder body shell, grooves are formed in the back surfaces of the lining bricks and cover the reinforcing ribs, the back surface of the lining plate is attached and fixed to the inner surface of the cylinder body shell, and every two adjacent lining bricks are spliced and fixed through mortises and tenons of the lining bricks. The efficient ball grinding mill is convenient to install and stable in structure.

Description

technical field [0001] The invention relates to the field of ceramic machinery, in particular to a high-efficiency ball mill with reinforcing ribs. Background technique [0002] Ball mill is a kind of machine commonly used in the ceramic production process. A common ball mill is mainly composed of a drum with a feeding port and a discharge port and a driving device; the driving device is mainly to drive the rotation of the drum. The drum is equipped with a lining plate, the abrasive will be ground during the rotation process. [0003] When the existing ball mill is used, the grinding material is first poured into the drum body, and then ground, because there are many ores with different textures and sizes in the grinding material, so the length of each grinding time is determined according to the most difficult ore to grind Yes, and in many cases, the grinding material taken out after grinding for a long time still has enough impurities. If the grinding time is estimated ba...

Problems solved by technology

[0003] When the existing ball mill is used, the grinding material is first poured into the drum body, and then ground, because there are many ores with different textures and sizes in the grinding material, so the length of each grinding time is determined according to the most difficult ore to grind Yes, and in many cases, the grinding material taken out after grinding for a long time still has enough impurities. If the grinding time is estimated based on these impurities that cannot be ground, it will greatly increase the grinding time and delay the progress of the process. The above reasons make It is very difficult to determine the grinding time of the ball mill and to ensure the quality of the ground material. Therefore, the fineness of the ball mill can only be guaranteed through long-term ball milling. How to improve the efficiency of the ball mill and reduce the energy consumption of the ball mill is a main direction for the improvement of the ball mill.

For this reason, people have developed a high-efficiency ball mill with a double-layer cylinder structure, but the interlayer space in the cylinder is small, so there are many problems in installing the liner on the inner wall of the cylinder. If the liner is fixed on the inner wall of the cylinder by screws, Because there is not enough space, it is very inconvenient to install and replace the liner. If the liner is fixed on the inner wall of the cylinder by pasting, the stability of the structure after the liner is installed cannot be guaranteed.
