In today's society, the process of urbanisation is accelerating and with it the problem of urban construction waste is becoming more and more prominent. The random abandonment and placement of construction waste will not only produce environmental pollution, but also cause serious impact on the health of everyone's life, and also cause serious pollution to the land. Therefore, to take reasonable measures to deal with the construction waste in the city has become an urgent task, and the emergence of construction waste treatment equipment can make this problem solved.

Commonly used construction waste treatment equipment, the main equipment includes: crusher, screening machine and conveyor belt.

The basic process is: crushing, screening, conveying, and in the appropriate links set up artificial or mechanical equipment to remove impurities, in order to generate recycled aggregates. For construction waste treatment, crusher is the key equipment in the whole process, this article mainly introduces the crushing equipment in construction waste treatment. There are countless construction waste treatment, but it can be roughly divided into two main categories, that is, according to the different ways of walking, the construction waste treatment equipment can be divided into two kinds of fixed and mobile. Fixed crushing and screening production line mainly consists of crushing machinery, screening machinery, conveying belt and feeder; mobile crushing and screening machinery mainly includes tyre-type mobile crushing plant and crawler-type mobile crushing plant.

1、Fixed construction waste treatment equipment

Fixed crusher can be divided into impact crusher, cone crusher, jaw crusher, roller crusher, hammer crusher, the crushing of construction waste is mainly used to crush by squeezing force and impact force, which are commonly used crushing methods. It is equipped with screening machinery, conveying belt and feeder to become a fixed construction waste treatment production line.

2、Mobile construction waste treatment plant

Mobile construction waste treatment equipment, as the name suggests, refers to the construction waste treatment equipment that can be moved. If fixed construction waste treatment equipment is used, the equipment can only be fixed in a certain place, and the construction waste will be transported to this place for treatment, which not only increases the transport cost, but also has the possibility of causing the second pollution. Mobile crushing plant can well solve this problem, it is a mobile construction waste treatment production line, which integrates feeding, crushing, screening, debris sorting device and transferring mechanism, and is equipped with mobile travelling equipment, which can be moved from one place to another according to the needs of the work, and realise long-distance travelling movement.

Mobile waste crushing plant mainly includes tyre mobile crushing plant and crawler mobile crushing plant, both of which have different types of mobile walking equipment. Tyre type mobile crushing plant needs vehicle-mounted generator set to provide continuous power source for the equipment. Crawler mobile crushing plant can move to the next station to continue working after working in one place according to the demand of the construction site, during which the placement of the equipment can also be adjusted without additional traction equipment.

Stationary crushing plant is generally used in construction waste treatment plant to build a fixed production line, but it is not easy to move; while mobile crusher is a mobile production line integrating feeding, crushing and screening.
