Efficient ball mill with annular grooves

Abstract

The invention relates to the field of ceramic machinery, in particular to an efficient ball mill with annular grooves. The efficient ball mill comprises a cylinder provided with a feed port and a discharge port, and a driving device; the driving device drives the cylinder to rotate; the cylinder is divided into two layers of tubular structures; the first layer is a cylinder outer shell; the second layer is a primary screening and grinding net pipe with sieve holes; grinding balls are respectively put in accommodating cavities between the inner surface of the cylinder outer shell and the outer surface of the primary screening and grinding net pipe; the feed port is connected with the accommodating cavity of the primary screening and grinding net pipe; the discharge port is connected with the accommodating cavities between the inner surface of the cylinder outer shell and the outer surface of the primary screening and grinding net pipe; lining plates are arranged in the cylinder outer shell; the contact surfaces between the back surfaces of the lining plates and the inner wall of the cylinder of the ball mill are corresponding arc surfaces; multiple grooves with arc sections are formed in the working surfaces of all the lining plates; and the connecting surfaces of the adjacent grooves are arc surfaces. The ball mill is an efficient ball mill capable of improving the grinding efficiency and quality.

Description

technical field [0001] The invention relates to the field of ceramic machinery, in particular to a high-efficiency ball mill with an annular groove. 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 b...

[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 canno
