Power plant slag crushing and reuse

Power plant slag crushing and reuse

With the development of industrialization, the production of slag from power plants is also increasing. Slag refers to the solid waste generated during the combustion of fuels such as coal and gas. Traditionally, slag is considered waste and is directly buried or stacked in open spaces. But this treatment method not only wastes resources, but also causes pollution to the environment. For this reason, more and more power plants are starting to crush and reuse slag. This article will introduce the methods and steps of crushing and reusing power plant slag.

1、 The principle of slag crushing

The principle of power plant slag crushing is to use mechanical force to crush the slag into smaller particles, which are then screened and graded. The purpose of slag crushing is to turn the slag into fine powder for reuse. There are various methods for slag crushing, such as mechanical crushing, hydraulic crushing, etc.

2、 Method of slag crushing

1. Mechanical crushing

Mechanical crushing is the use of mechanical force to crush slag into smaller particles. There are various methods for mechanical crushing, such as hammer crusher, impact crusher, cone crusher, etc. The advantages of mechanical crushing are high production efficiency, but the disadvantages are high noise, high energy consumption, and easy to generate dust pollution.

2. Hydraulic crushing

hydraulic crushing is the use of hydraulic force to crush slag into smaller particles. There are various methods for hydraulic crushing, such as hydraulic crushers, hydraulic cyclone crushers, etc. The advantages of hydraulic crushing are low noise, low energy consumption, and less prone to dust pollution, but the disadvantage is low production efficiency.

III. Method of slag crushing and reuse

1. Concrete mix

After crushing the slag, it can be used as a concrete mix. The crushed slag particles are smaller and can fill the voids in the concrete, increasing its compactness and strength. The crushed particles of slag can also absorb moisture from the concrete, reduce its shrinkage rate, and improve its durability.

2. Pavement materials

The crushed slag can be used as road material. The crushed slag particles are smaller and can fill the gaps in the road surface, improving the compactness and durability of the road surface. The crushed particles of slag can also absorb moisture from the road surface, reducing flooding and damage to the road surface.

3. Mortar

The crushed slag can be used as mortar. The crushed slag particles are smaller and can fill the gaps in the mortar, improving the compactness and adhesion of the mortar. The crushed particles of slag can also absorb moisture in the mortar, reduce the shrinkage rate of the mortar, and improve the durability of the mortar.

4、 Summary

The crushing and reuse of power plant slag is a good method to save resources and protect the environment. After being crushed, slag can be used as concrete mix, pavement material, mortar, etc., which can improve the density and durability of the material and reduce the flooding and damage of the material. The methods of slag crushing and reuse include mechanical crushing and hydraulic crushing, and different methods can be selected according to different production needs.
