The invention discloses an ultra-high-speed fine pulverizing grinder, which relates to the field of calcium carbonate processing, and aims to solve the problem of uneven particle size of calcium carbonate particles obtained by grinding the existing grinder, and its technical points include a casing and a grinding lining Ring, grinding ring and driving support shaft, the driving support shaft is installed between the upper and lower inner surfaces of the casing, the casing is provided with a driving device for driving the driving support shaft to rotate, and the grinding ring passes through the chain along the The vertical direction is arranged at intervals on the peripheral wall of the drive shaft. The grinding lining ring is arranged on the inner vertical peripheral wall of the casing and is located on the peripheral side of the grinding ring. The grinding lining ring is opposite to the grinding ring and forms a grinding chamber. , the diameter of the outer ring of the grinding ring increases gradually along the vertical direction, a material guide is arranged between two adjacent grinding chambers, a feeding hopper is arranged on the top of the casing, and the bottom of the casing There is a discharge hopper at the end. The invention can realize the gradual grinding of materials to obtain calcium carbonate particles with more uniform particle diameters.
Description
technical field [0001] The invention relates to the field of calcium carbonate processing, more specifically, it relates to an ultra-high-speed fine pulverizing grinder. Background technique [0002] Nano-calcium carbonate, also known as ultra-fine calcium carbonate, is widely used in the fields of plastics and building materials; for the preparation of nano-calcium carbonate, carbon dioxide gas is introduced into a suspension of calcium hydroxide with a certain concentration for carbonization, so that the hydrogen oxidizes Calcium reacts with calcium dioxide to obtain calcium carbonate, and then grinds the generated calcium carbonate to obtain nano-calcium carbonate with a specified particle size. [0003] Existing application number is the Chinese patent of CN201020699678.0, discloses a kind of superfine powder calcium carbonate grinder, comprises cylinder body, and the stirring device driven by power unit is arranged in the cylinder body, and the upper part of cylinder bo...
