Concrete Screening Introduction
Concrete is one of the most important materials for civil construction. With the acceleration of urbanization, people have raised higher requirements for concrete quality. And since the demand of sand aggregate of our society is increasing rapidly, it is necessary to process waste concrete into new concrete aggregate to solve the problem of aggregate lack.
Concrete Screening Process
The waste concrete processing is not quite different from that of concrete aggregates making. The waste concrete is firstly crushed into large concrete materials, and then transported by a truck to stock ground which is normally situated near the reconstruction project in order to save transport cost. The concrete materials are then crushed by jaw crusher and cone crusher , and screened by vibrating screen .
For cement concrete pavement recycle, at least 75% of the materials should be crushed into small grains. The surface of the pavement concrete should be reduced into grains less than 7.5cm in size, the interlayer of the pavement concrete into grains less than 22.5cm in size, and the basement materials into grains less than 37.5cm in size. In order to control crushed concrete granularity, you will need screening equipments to separate coarse particles from the product. grains of required size are moved to the following process, while the large one will be sent back to concrete crushers for further crushing.
Concrete screens for waste concrete recycle
In order to satisfy the market demand for used concrete screening equipments, NFLG has developed its own series of vibrating screens for concrete recycle. NFLG has more than 30 years of experience in designing and constructing mining and construction equipments, and our concrete aggregate screening equipment of international level has occupied great market share as a result of its advantages like high efficiency, high reliability, low noise, and low consumption. The sieve pore size ranges from 3-50mm to 5-150mm, and its processing capacity from 7.5t/h to 700/h.
Apart from the stationary vibrating screen, we also provide you with portable crushing and screening plant of international level which is more flexible and combines crushing and screening process together by one single machine. It is favored by our customers for the integrality, flexibility, lower production cost and reliable performance.
