Abstract

The invention discloses a screening device for calcium powder production. The screening device comprises a shell, the top of the shell is provided with a feeding bin and a negative pressure suction port, the bottom of the feeding bin is in a funnel shape with larger upper portion and smaller lower portion, the lower portion of the feeding bin is provided with a screening mechanism, the bottom of the feeding bin is provided with a discharging mechanism used for discharging calcium powder which does not reach the standard, the screening mechanism comprises a plurality of discharging holes formed in the side face of the lower portion of the feeding bin, each discharging hole is rotationally provided with a screening barrel communicating with the discharging hole through a slewing bearing, screening holes are formed in the screening barrels, spiral blades are arranged on the inner walls of the screening barrels, the upper ends of the spiral blades extend into the feeding bin, blocking plates are arranged at the lower ends of the screening barrels, and fixing shafts are arranged at the bottoms of the blocking plates. According to the screening device for calcium powder production, the multiple synchronously-rotating screening barrels are adopted for screening calcium powder, meanwhile, the screened calcium powder is collected in a centralized mode through negative pressure provided by the negative pressure suction opening, and the calcium powder screening efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of calcium powder screening equipment, in particular to a screening device for calcium powder production. Background technique [0002] With the development of society and science and technology, mills are constantly being updated. From the original Raymond mill, it is mainly used in the mining industry of more than 280 kinds of materials such as marble, limestone, calcite, etc. whose Mohs hardness is not greater than 7. Chemical powder processing, to a new type of mill to replace Raymond mill, calcium powder is the main component of limestone and calcite, usually used as filler, also widely used in rubber, plastic, paper, paint, ink, cable, construction supplies, Food, medicine, textile, feed, toothpaste and other daily chemical industries, used as a filler to increase the volume of the product and reduce production costs. Calcium powder is mainly white stone with a calcium carbonate content of more than 90...
