As a substitute for natural sand, artificial sand effectively fills the gap in the market demand for sand and gravel. With the development of the infrastructure industry and the emphasis on the quality of construction projects, the quality of sand is also increasingly required. The quality of artificial sand directly affects the quality of concrete, so it is very important to improve the quality of artificial sand.

High-quality artificial sand can meet the sand needs of different construction projects, so how to produce high-quality artificial sand?

 

1. Raw materials for sand making

 

Raw materials are the key to processing artificial sand. Some raw materials themselves are mixed with more impurities such as soil and dust. The raw materials are not clean, and the quality of artificial sand processed naturally is not high. Not all materials can be used to produce artificial sand. When producing artificial sand, there are certain requirements for materials. Select raw materials with appropriate lithology, such as granite, limestone, etc. These raw materials have high compressive strength and appropriate chemical composition, which can ensure the strength and durability of artificial sand.

 

2. Machine-made sand processing equipment

 

The quality of machine-made sand aggregate is mainly based on the particle size and grading requirements of the material. The use of efficient crushing equipment, vibrating screens and suitable square hole screens can control the particle size of sand and gravel to a certain extent. Therefore, it is important to choose suitable processing equipment.

 

3. Human factors

 

The professional technical level and quality awareness of the operator are important factors affecting the quality of sand and gravel. The organizers and managers involved in this project also have a certain degree of influence on the quality of the project. Therefore, in order to effectively ensure the quality of the project, it is necessary to control the human factors. Improve the professional skills of relevant personnel, continuously educate the labor discipline of relevant personnel, and comprehensively enhance their quality.

 

4. Processing technology

 

According to different process characteristics, choose appropriate processing technology methods in different situations.  Mechanical sand production process: The basic production process can generally be divided into the following stages: coarse crushing → medium crushing → fine crushing (sand making) → screening → sand washing.

 

A complete machine-made sand production line can be divided into three parts: crushing, sand making, and sand washing. The machine-made sand processing equipment involved includes vibrating feeder, jaw crusher, cone crusher, impact crusher, vibrating screen, vertical impact sand making machine, sand washing machine, belt conveyor, centralized electronic control equipment, etc.
