Problems solved by technology

[0004] When the existing mill is in use, the ground powder may stick to the grinding surface of the mill. When the powder sticks to the grinding surface more, the grinding surface will be uneven, and the grinding roller will appear when the grinding roller is attached to the grinding surface. The gap causes no points in the grinding, which affects the grinding effect and prolongs the grinding time

Abstract

The invention relates to the technical field of ore smashing equipment, in particular to a powder grinding machine for preparing calcium carbonate powder. The powder grinding machine comprises a mainmachine body. A smashing cavity is formed in the main machine body. The main machine body is provided with a feeding port and a discharging port. A grinding assembly is arranged in the main machine body. The grinding assembly comprises a main shaft, a plurality of grinding rollers and a driving part used for driving the main shaft to rotate. The main shaft is arranged vertically and located at thecenter position of the inner bottom wall of the main machine body. The grinding rollers are installed on the main shaft and distributed at intervals. The position, attached to the grinding rollers, in the main machine body is provided with a grinding face. The main shaft is provided with a scraping cutter attached to the grinding face. According to the powder grinding machine, the scraping cutterscrapes dust on the grinding face, thus grinded powder is not prone to sticking to the grinding face of the powder grinding machine, and then the powder grinding machine has the advantages of not influencing the grinding effect easily and prolonging the grinding time.

Description

technical field [0001] The invention relates to the technical field of ore crushing equipment, in particular to a mill for preparing calcium carbonate powder. Background technique [0002] Calcium carbonate powder is powdery calcium carbonate, which plays an important role in the water-based coating industry, construction field and chemical industry. When preparing calcium carbonate powder, the calcium carbonate raw material is crushed and then ground with a mill. [0003] The Chinese patent with the notification number CN204448163U discloses a suspension roller mill with a double-layer air inlet channel, including a base, a grinding roller arranged on the base, a middle body, and an air inlet channel arranged between the base and the middle body. The air inlet channel is composed of an upper channel and a lower channel. The middle body is fixed on the upper channel by bolts; a shunt cover is set between the grinding roller and the middle body, and the interlayer formed betw...
