Description

Movable concrete crusher

Technical Field

The utility model relates to a concrete grinder technical field specifically is a portable concrete grinder.

Background

Concrete is called concrete for short, and refers to a general name of engineering composite materials formed by cementing aggregates into a whole by cementing materials, and is widely applied to civil engineering. Concrete is one of the most important civil engineering materials of the present generation. The artificial stone is prepared by a cementing material, granular aggregate (also called aggregate), water, an additive and an admixture which are added if necessary according to a certain proportion, and is formed by uniformly stirring, compacting, forming, curing and hardening. The concrete has the characteristics of rich raw materials, low price and simple production process, so that the consumption of the concrete is increased more and more. Meanwhile, the concrete also has the characteristics of high compressive strength, good durability, wide strength grade range and the like. These characteristics make it very widely used, not only in various civil engineering, that is shipbuilding, machinery industry, ocean development, geothermal engineering, etc., but also concrete is an important material. When an existing concrete structure is maintained or reconstructed, most of concrete blocks poured before are directly excavated and stacked or buried, but the concrete blocks are not easy to rot due to high strength, and the land blocks can not be used after being stacked or buried for a plurality of years, so that resource waste and land burden are caused. At present, an efficient concrete crusher is urgently needed in engineering to change concrete blocks into recyclable resources.

However, the concrete crusher is heavy and difficult to move, and a mobile concrete crusher is needed.
