Equipment for recycling and processing construction waste

Abstract

The invention relates to an operating method of equipment for recycling and treating construction waste, and belongs to the technical field of crushing equipment. The equipment comprises a hopper, wherein the hopper is used for containing construction waste, and two movable jaw plates which are used for crushing the construction waste are respectively installed on both opposite side surfaces of the hopper; an impact power part is arranged above the hopper, a curved pressing plate is hinged to the hopper, and the impact power part alternately acts on both opposite sides of the curved pressing plate, so that the movable jaw plates on the corresponding sides are alternately driven to move on the hopper by the curved pressing plate. According to the operating method, the construction waste istreated in a rubbing mode like washing clothes, the movable jaw plates only have the effects of supplying impact and pushing, and the friction effect between the construction waste is used to the maximum, so that the probability of friction contact between metal of mechanical equipment and the construction waste, especially rebar materials in the construction waste, is avoided, the wear of the mechanical equipment is reduced, the service life of the equipment is prolonged, and the productive maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to equipment for recycling and processing construction waste and its operating method. Background technique [0002] China's construction market is huge, and countless construction wastes are generated every year. Most of the construction materials are reinforced concrete or masonry structures, and many of them can be recycled. On the one hand, the amount of waste generation can be reduced. Reprocessed as raw materials, turning waste into treasure, and metal structures such as steel bars can also be recycled. [0003] When crushing masonry materials, people use crushers. Commonly used crushing machines include jaw crushers, impact crushers, vertical impact crushers, hydraulic cone crushers, ring hammer crushers, hammer crushers, and roller crushers. Crusher, Compound Crusher, Cone Crusher, Double Crusher, Gyratory Crusher, Mobile Crusher, etc. [0004] Among them, the m...

Problems solved by technology

However, this jaw crusher still adopts the principle of "iron millstone" to crush the mineral raw materials head-on with metal plates. On the one hand, the wear rate of the movable jaw plate and the static jaw plate is relatively fast. On the other hand, when assembling, The crushing plate must be firmly attached to the jaw plate, and the space between the two should be flat. Soft metal (such as lead, zinc, etc.) should be used as a gasket between the crushing plate and the jaw plate, and fastened with bolts.

When the crusher is working, the crushing plate is prone to loosening under repeated impact, and once loose, it will break or wear the crushing plate, reduce the service life of the crushing plate, and generate great vibration and noise

[0012] In terms of crushed materials, jaw crushers are also not suitable for crushing materials mixed with metal. The crushing plate cannot crush the metal, but is accelerated by the metal.
