Description

Technical Field

[0001] The present application relates to the technical field of dry-mix mortar production, and in particular to a raw material crushing device for dry-mix mortar production. Background Art

[0002] Dry-mix mortar is a mixture of cement, dry aggregate or powder, additives and other components determined by performance, which are measured and mixed in a certain proportion in a professional production plant. It has been widely used in construction projects. In the production process of dry-mix mortar, crushing the raw materials is a crucial link. The particle size of the crushed raw materials is more uniform, which can improve the uniformity of mixing, thereby ensuring the stable quality of the dry-mix mortar. In addition, the smaller particle size is conducive to improving the construction performance of the mortar, such as fluidity and density.

[0003] In related technologies, traditional crushing equipment such as jaw crushers and impact crushers are usually used to crush raw materials. These devices mainly crush larger particles of raw materials into smaller particles through mechanical forces such as extrusion, impact, and shearing.

[0004] The working principle of the jaw crusher is mainly to squeeze and crush the material through the circular motion between the movable jaw and the fixed jaw. This mode of motion determines that the number of times it processes the material per unit time is relatively limited, and the crushing action is relatively simple, which makes it difficult to further improve the crushing efficiency. In addition, the jaw plate spacing of the jaw crusher is determined when the equipment is designed and manufactured, and the adjustment range is relatively small. For materials that require fine crushing, it may not be possible to crush the material to a small enough particle size, and it is difficult to meet the production needs with high requirements for crushing fineness; the impact crusher mainly relies on the high-speed impact of the plate hammer on the material to achieve crushing. However, the impact angle and number of blows of the plate hammer are to a certain extent limited by the equipment structure and working principle. If the impact angle is unreasonable or the number of blows is insufficient, it cannot fully exert the crushing effect on the material, which also leads to the problem of low crushing efficiency.
