Application Advantages and Production Technology of Reclaimed Sand Equipment

Waste concrete is the waste concrete block produced by building demolition, road repair, concrete production, engineering construction or other conditions. The waste concrete can be recycled into fine aggregate after crushing processing. In the production equipment used in the foundry industry, recycled sand equipment is also a relatively common one. It is used in the foundry industry because many of its advantages are applicable to today's foundry companies. The application advantages of recycled sand equipment are also closely related to its production process. Therefore, their production and design have adopted good materials and mature technology, which will give them application advantages. There will be more and more.

The fixed operating cost of recycled sand equipment is relatively small, the cost of production line related machinery and equipment is relatively low, and the source of clay sand can generally save a lot of material and labor costs for enterprises. And recycled sand equipment without drying, saving energy. The production line has obvious performance advantages and strong practicability. The old sand can be reused after regeneration treatment, the regeneration process is relatively simple, and the operating cost is not too high. Recycled sand equipment is simple to operate, requires low technical personnel, and usually can be operated without professional training. Therefore, it is relatively easy to recruit workers, which can save human capital for enterprises.

Every year, tens of thousands of tons of waste concrete are produced after the demolition of a large number of buildings, of which aggregate accounts for a large proportion of waste concrete.

Therefore, the development and utilization of aggregate in waste concrete can not only solve the problem of waste concrete treatment, but also save natural sand and gravel, and bring good social, economic and environmental benefits.

The production process of waste concrete recycled aggregate is similar, which combines different cutting and crushing equipment, conveying equipment, screening equipment and impurity removal equipment to complete the process of crushing, screening and impurity removal, and finally get recycled aggregate.

Practice shows that the recycled aggregate of waste concrete simply crushed by jaw crusher has many edges and corners, rough surface, and hardened cement mortar attached to the surface. In addition, due to the accumulation of damage during the crushing process, a large number of microcracks are generated inside, resulting in large porosity, high water absorption, low bulk density, and high crushing index of the recycled aggregate. Therefore, in order to improve the performance of waste concrete recycled aggregate, it is necessary to select the correct equipment to shape the recycled aggregate.

recycled sand equipment recommend:

(1) The vertical shaft impact crusher adopts the principle of "stone to stone" and "stone to iron", which can make waste concrete into recycled aggregate and adjust the size of 4.75mm sand;

(2) The 5x sand making machine is also a common reclaimed sand equipment with high discharge efficiency and stable performance. It is a relatively advanced equipment.

If the reclaimed sand equipment needs to be operated by professionals during operation, it is necessary to follow the relevant management system to ensure the safety factor in the specific steps of operation. At the same time, when the reclaimed sand equipment is working, it is necessary to carry out the oil injection operation on time in accordance with the relevant specifications to avoid the problem of blockage of the oil circuit. At the same time, should be timely cleaning oil cup, linoleum and other parts.
