Description

Technical Field

[0001] The utility model relates to the technical field of mortar grinding, in particular to a raw material grinding device for special mortar production. Background Art

[0002] Special mortar is a type of mortar, which is mainly suitable for mortars with special requirements such as thermal insulation, sound absorption, waterproofing, corrosion resistance, radiation protection, decoration and bonding. In the production process of special mortar, the raw materials will be ground by a grinding device to facilitate the later deep processing;

[0003] Although the existing grinding device can achieve the grinding effect, the grinding effect is not very good, and slightly larger particles are mixed in it, and the grinding is not thorough, which affects the subsequent processing;

[0004] A Chinese patent (Announcement No.: CN217614998U) discloses a raw material grinding device for special mortar production, in which two crushing rollers are arranged inside the main box, and the two crushing rollers rotate in opposite directions through the cooperation of the main gear and the slave gear, so that the raw material can be crushed first, so that the grinding rotor can grind the crushed raw material more finely in the later stage;

[0005] Although the existing technology has solved the problem of incomplete grinding and affecting the later processing, it still has certain defects. The device grinds the mortar raw materials through two grinding rollers, and the crushed raw materials are then filtered through a V-shaped filter plate. Although the V-shaped filter plate used in the device is inclined on both sides, during the screening process, larger particles of raw materials will still be stuck in the sieve holes and cannot continue to slide down. Therefore, with continuous screening, the sieve holes of the filter plate will be completely blocked. When the V-shaped screening plate is completely blocked, the crushed raw materials will not be able to continue to fall down through the sieve plate, and they cannot be ground.
