Description

Technical Field

[0001] The utility model relates to the technical field of mortar production, in particular to a high-efficiency crushing device for premixed mortar production. Background Art

[0002] Mortar is the bonding material used for bricklaying in construction. It is made of a certain proportion of sand and binding materials (cement, lime paste, clay, etc.) and water. It is also called mortar or mortar. Commonly used mortars include cement mortar, mixed mortar (or cement lime mortar), lime mortar and clay mortar. During the mortar production process, crushing equipment is required to crush some gravel. After crushing, these gravel can reach the specifications of coarse aggregate or fine aggregate so that they can be used as raw materials for mortar production.

[0003] At present, when some impact crushers are crushing stone raw materials for mortar, some stones are very wet due to stacking or rain, resulting in a high water content in the stone raw materials. When such stones enter the crusher for crushing, some stone powder residues are easy to adhere to and accumulate on the impact frame or the inner wall of the crusher, affecting the crushing efficiency of the crusher, and further affecting the raw material production efficiency of the premixed mortar. For this reason, we propose an efficient crushing device for the production of premixed mortar. Utility Model Content

After the hot air enters the crusher body, under the action of high hot wind force, a hot air crushing chamber environment is maintained in the crusher body. When slag is thrown at the inner cavity of the crusher body after the wet gravel is crushed, the hot air can dry the slag, so that the dried slag falls with the vibration of the crusher body when it is working, so that the problem of sticking stone slag that affects the crushing efficiency will not be generated in the crusher body, thereby ensuring the efficient crushing of the premixed mortar raw materials and effectively solving the problems in the background technology.
