Description

Technical Field

[0001] The utility model relates to the field of mortar crushers, in particular to a circulating crusher for dry-mixed mortar. Background Art

[0002] Dry-mixed mortar is a pre-mixed building material, mainly composed of cement, lime, sand and specific additives. These raw materials are mixed and stirred in advance in a factory or production site. When using it, the user only needs to add an appropriate amount of water and stir it evenly. When producing dry-mixed mortar, multiple materials need to be mixed and crushed, and the existing crushers are difficult to meet the standards when crushing at a single time. Therefore, a circulating crusher for dry-mixed mortar is proposed.

[0003] When existing crushers crush mixed materials, it is relatively difficult to crush all the materials in one time. Therefore, workers are required to transport the crushed materials for a second time, which is relatively troublesome. In addition, existing crushers cannot effectively filter and screen the crushed materials, which may result in materials that do not meet the crushing standards in the crushed materials, thereby affecting the quality of the mortar. For this reason, technical improvements are urgently needed. Utility Model Content
