Construction waste crushing process

The development of infrastructure business is in full swing, which produces a large amount of construction waste, resulting in a large accumulation of construction waste. The massive accumulation of construction waste not only pollutes the environment, but also consumes manpower and material resources to deal with, which is enough to show that construction waste has great potential for development, and its crushing sand used in the construction industry instead of mechanical sand not only alleviates the situation of sand shortage, but also effectively solves the problem of pollution of the environment by construction waste, which is the best of both worlds. Let's take a look at how the process of construction waste crushing turns construction waste into treasure.

Generally need to go through the following processing:

1. Pre-treatment: not all materials in the construction waste can be reused, some materials will cause damage to the crushing equipment, so we need to carry out pre-treatment. Pre-treatment is to pick out the steel products and wooden products inside the construction waste, cut off the long steel bars to prevent damage to the conveyor belt, sort and remove the large pieces of debris, and so on.

2. Feeding: After pre-processing, the raw materials of construction waste should be sent to the feeding port of the crusher through the vibrating feeder. The vibrating feeder can feed the materials evenly and uninterruptedly, so as to ensure the smooth progress of the whole construction waste recycling production line.

3. Primary crushing: The primary crushing equipment is the jaw crusher, its main role is to break the large pieces of construction waste into smaller construction waste, so as to ensure that it can reach the size of the feed size of the later equipment. Not only that, the equipment adopts high wear-resistant tooth plate, the maintenance cycle is longer, which can reduce our expenditure.

4. Secondary crushing: After processing through the primary crusher, the material of construction waste is sent to the secondary crushing equipment through the conveyor, and the secondary crushing equipment is impact crusher, the finished product of the impact crusher has uniform particle size, and most of the finished products are cubic, with good particle size.

5. Screening: After the secondary crushing of construction waste materials need to go through the vibrating screen machine, screening out different specifications of the finished sand, the non-compliance of the secondary crushing equipment to re-processing, in order to ensure that the grade of the finished material requirements.

Crushed construction waste can be used to do recycled aggregates, can also be used to produce the corresponding strength level of concrete, mortar, sidewalk bricks, wall panels, floor tiles and other building materials, coarse and fine aggregates added to the curing materials, can also be used for highway pavement grass-roots level. Mixed material: mainly used for road subgrade, soft base treatment, grassroots level and mixed with a portion of stone cement used as water stabilization layer.
