Description

Gravel grinding and crushing safety screening device

Technical Field

The invention relates to the field of sandstone preparation, in particular to a safe screening device for sandstone grinding and crushing.

Background

Because of its good hardness and stable chemical properties, sandstone is often used as a high-quality building material and concrete raw material and is widely applied in the fields of houses, roads, highways, railways, engineering and the like. With the requirements of infrastructure construction technology and the development of high technology, higher requirements are made on the quantity and quality of sand. Sand is a loose material, but its particles are generally hard and chemically stable in the surface environment. Sandstone generally has stronger weather resistance, and particularly, siliconized quartz sandstone has hardness higher than granite. The sandstone is a basic material in national economic construction, is mainly used for basic engineering, concrete, mortar and corresponding products, and is an indispensable and irreplaceable aggregate material for building of basic facilities such as buildings, roads, railways, bridges, municipal engineering, hydraulic engineering, hydroelectric engineering, nuclear power station engineering, airports, wharfs and the like. At present, the cement concrete and the asphalt concrete are most widely applied in engineering construction, and the polymer concrete is less in use amount. Concrete is a composite material and sand is one of the major component materials in the largest proportion. In a concrete structure, the sand and stone mainly play a role of a skeleton, stabilize the volume of concrete, transfer stress, inhibit shrinkage and prevent cracking. Plays an extremely important role in building and infrastructure, namely, no sand, no concrete and no concrete building and foundation engineering.

Now, in order to meet more and more construction projects and increasingly reduced sandstone resources, more stones are broken into sandstone, so that the construction is convenient to use. The sandstone is generally required to be screened after preparation, and the sandstone often easily blocks sieve pores during screening, thereby influencing the screening of the sandstone and influencing the use.
