Problems solved by technology

However, because it adopts a single-stage crushing method, the conveyed waste is uniformly crushed by the rotating drum regardless of the size of the individual, and it can only output coarser particles within a certain range. Not to mention the low crushing efficiency, it also causes the crushed products to be recycled. There are great limitations in the use of
To a certain extent, the output result cannot meet the standard of reuse, so the technical scheme and crushing means of the equipment need to be further improved.

Abstract

The invention relates to the field of building equipment, in particular to a building waste crushing device. The building waste crushing device mainly comprises a vertical material distributing channel; the middle portion of the material distributing channel is provided with a material distributing screen roller; and thick and large waste is guided into a thick material crushing device to be crushed by the material distributing screen roller, and thin waste is guided into an intermediate material crushing device to be crushed. The building waste crushing device aims to solve the problems thatin the prior art, the device is used for crushing large waste and small waste in different crushing ways and means, and therefore the crushing efficiency is greatly improved, and the crushing effect is optimized. Products after crushing by the building waste crushing device can be applied to various recycling in building engineering.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a construction waste crushing device. Background technique [0002] In the existing technical field of building materials production, the production of building materials, especially the production of concrete blocks, is likely to cause damage to the blocks due to bumps during molding, maintenance and handling. Such blocks can no longer be used for masonry, but are discarded directly. It will not only pollute the environment, but also lead to an increase in production costs. Therefore, the conventional treatment method is to break the block waste into powder or small particles and then reprocess it as a raw material. [0003] For example, Japanese Patent Publication No. 6-30755 discloses a method and device for recycling concrete fragments, which is a method for crushing and grading disintegrated concrete pieces of buildings, civil structural parts, concrete secondary produc...
