Aggregate crusher for cement base material processing

Abstract

The invention discloses an aggregate crusher for cement base material processing. The aggregate crusher comprises a box body and supports mounted at the four corners of the lower portion of the box body, an automatic extrusion crushing type upper millstone device is arranged on the upper portion in the box body, and a circulating jet type lower millstone device is arranged on the lower portion in the box body. According to the aggregate crusher, an upper millstone rotates to drive sector-shaped extrusion blocks to conduct reciprocating angle adjustment, and cement base materials can be extruded, crushed and ground at the same time through reverse rotation of the upper millstone and a lower millstone, so that the crushing efficiency of the cement base materials is improved; due to the fact that a gap between the upper millstone and the lower millstone is large, the cement base materials can enter the gap between the upper millstone and the lower millstone more easily, crushing of the cement base materials is effectively facilitated, and the crushing efficiency is improved; and through rotation of the lower millstone and use of a circulating fan, the crushed cement base materials can be rapidly discharged into the box body, and the situation that the cement base materials are slowly discharged, and consequently crushing work is affected is avoided.

Description

technical field [0001] The invention relates to the field of equipment related to cement production and processing, in particular to an aggregate crusher for cement substrate processing. Background technique [0002] Cement, powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in air or in water, and can firmly bind sand, stone and other materials together. In the early years the mixture of lime and volcanic ash is very similar to lime pozzolanic cement, use it to glue concrete which made of crushed stone. After hardening, the cement not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, cement, as an important cementitious material, has been widely used in civil engineering, water conservancy, national defense and other projects. [0003] In the process of cement production, it is necessary to crush the cement base material and crush the aggregate into ...

Problems solved by technology

[0003] In the process of cement production, it is necessary to crush the cement base material and crush the aggregate into fine particles, thereby facilitating the preparation of cement. However, when the existing pulverizer is crushing cement, the crushing efficiency is low, resulting in cement Substrate wastes a lot of time when shredding
