Description

Concrete production stone screening plant

Technical Field

The utility model relates to a stone screening technical field specifically is a concrete production stone screening plant.

Background

The common concrete is artificial stone which is prepared by taking cement as a main cementing material, adding water, sand, stones and chemical additives and mineral admixtures if necessary, mixing the materials according to a proper proportion, uniformly stirring, densely molding, curing and hardening. Concrete is mainly divided into two stages and states: plastic state before setting and hardening, namely fresh concrete or concrete mixture; hardened, i.e. hardened concrete or concrete. The concrete strength grade is divided into a cubic compressive strength standard value, and the Chinese common concrete strength grade is divided into 14 grades: c15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80.

At present, most of the stones in the concrete production process are not perfect enough in screening facilities, stones meeting the specification cannot be screened out from a stone pile, after the stones meeting the specification are screened out, stones with overlarge specifications and stones with undersize specifications are mixed together again, the recycling of the remaining stones is inconvenient, when stones with another specification are needed, the stones need to be screened again, time and labor are wasted, and the cost is increased.
