Problems solved by technology

[0003] However, whether it is a Raymond mill or a new type of mill on the market, they all use first-stage milling, and the obtained calcium powder has a larger particle size. The fine calcium powder mill further grinds the calcium powder, which not only increases equipment investment, but also has low efficiency

Abstract

The invention discloses a grinding device for calcium powder production. The device comprises a shell, wherein a feed hopper is arranged on the upper portion of the shell; a transverse partition plate is arranged at the position, close to the bottom, of an inner cavity of the shell, so that the inner cavity of the shell can be divided into an upper grinding cavity and a lower driving cavity; a negative pressure suction port is arranged in the side wall of the lower portion of the grinding cavity; a primary grinding mechanism is arranged on the transverse partition plate; an annular powder collecting groove is arranged in the peripheral side of the primary grinding mechanism through a first connecting rod; a plurality of guide barrels are arranged at the bottom of the powder collecting groove in a communicating mode; a secondary grinding mechanism is arranged under each guide barrel; and a cooperative driving mechanism for cooperatively driving the primary grinding mechanism and the secondary grinding mechanism is arranged in the driving cavity. By means of the grinding device, the primary grinding mechanism can be used for conducting primary grinding on calcium powder raw materials, the multiple secondary grinding mechanisms can be used for conducting secondary grinding on calcium powder obtained after primary grinding at the same time in order to obtain calcium powder smaller in fineness, the equipment investment is small, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of calcium powder mills, in particular to a milling 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%, which is crus...
