Grinding host discharging and screening mechanism

Abstract

The invention provides a grinding host discharging and screening mechanism including a feeding pipe, a screening machine and a discharging pipe which are sequentially arranged from top to bottom. Theside of the screening machine is further provided with a returning pipe inclined downwards. The grinding host discharging and screening mechanism further includes a vertically-arranged lifting conveyor, one end of the lifting conveyor is connected with the returning pipe, the other end of the lifting conveyor is connected with a crushing machine, an outlet of the crushing machine is connected withthe side of the feeding pipe, the screening machine includes a cylindrical casing and an impeller coaxially disposed in the casing. According to the grinding host discharging and screening mechanism,screening is performed through the impeller perpendicular to the feeding pipe, and the screening efficiency is not greatly affected when the screening surface is small, which can greatly improve thescreening efficiency, does not cause a clogging situation and reduces maintenance time and cost. The sizes of particles screened can also be adjusted through the rotating speed of the impeller, so asto cooperate with different grinding machine configurations and different rotating speeds to perform most reasonable arrangement, to obtain powder products with better quality.

Description

Technical field [0001] The invention relates to the field of grinding equipment, in particular to a sieving device used for cooperating with a grinding host when cutting materials. Background technique [0002] Powder manufacturing is a very important part of modern industry. For fine processing of various ores such as calcium carbonate and barium sulfate, they need to be pre-processed into powder and then processed. At the same time, the refined development of modern industry has also continuously increased the requirements for powder products. The existing powder production line is processed by using a grinder, and the powder product is transported by a conveyor belt and stored in a storage room. [0003] Large grinders are usually equipped with continuous feeding devices to maintain uninterrupted grinding processing. However, in many cases, the size of the ore raw materials provided is inconsistent. Some raw materials are too large, which will cause insufficient processing in t...
