Description

Technical Field

[0001] The utility model relates to the technical field of micro powder pulverizers, in particular to a micro powder pulverizer for preparing nano calcium carbonate. Background Art

[0002] A micro powder grinder is a machine specially used to process granular materials into fine powder. It is widely used in medicine, chemical industry, food and other fields. Micro powder grinders used for the preparation of nano calcium carbonate usually have the characteristics of high precision, high efficiency and low energy consumption. They can achieve ultrafine grinding and classification of raw materials to meet the process requirements of nano calcium carbonate preparation.

[0003] A nano-calcium carbonate preparation micro-powder pulverizer disclosed in the patent application with reference publication number CN117509196A includes a cutting machine body, a cutting assembly is provided on the cutting machine body, an inclined slider is vertically slidably mounted on the upper end of the cutting machine body, a rear baffle is horizontally slidably mounted on the upper end of the rear side of the cutting machine body, and side support plates are installed on both the left and right ends of the cutting machine body. The utility model inserts the side plug rod 1 of the side support plate into the side slot 1, and the rubber pad can play a filling role and has an anti-slip effect. When the side plug rod 1 is inserted into the side slot 1, the two side plug rods 2 will be synchronously inserted into the two side slots 2. At this time, the side support plates and the cutting machine body are installed. Since the side support plates are in an inverted hook shape, when the exterior wall insulation board falls, the exterior wall insulation board will stay on the side support plates to prevent the exterior wall insulation board from falling and being damaged, further improving the convenience of taking. The device improves the convenience of taking the cut exterior wall insulation boards by setting side support plates, but the device requires manual operation to load and unload the materials. The cutting process of the insulation boards will generate dust. Industrial dust is harmful to human health and will pollute the working environment.

[0046] Working principle:

[0047] The crushing assembly 6 adopts the cutting assembly in CN117509196A, which is a prior art and will not be described in detail.

[0048] The raw materials for preparing nano calcium carbonate are loaded into the crushing box 3, and the raw materials are crushed by the crushing assembly 6. The crushed raw materials pass through the filter screen 8 and enter the collection frame 7;

[0049] When a batch of raw materials is crushed, the motor 13 is started to drive the rotating shaft 14 to rotate.
