Many people in "sand" and "sand" are not clear. What is the difference between the two? 又是如何生产的呢？ How is machine-made sand produced? Don't worry, Shanghai Wei Li can answer your questions.
"Sand" as its name implies is finely divided stone particles produced in nature, such as: aeolian sand, dust storms, deserts, beaches, etc .; and "sand" is mostly artificial and can be divided into two types: natural sand and mechanical sand. As time goes by, mechanical sand replacing natural sand has become an inevitable trend in the development of the industry.
1. Which raw materials can produce machine sand?
In general, machine-made sand can be produced from stones of comparable hardness. Specifically, production principles include pebbles, limestone, granite, basalt, andesite, sandstone, quartzite, diabase, tuff, marble, rhyolite, iron ore; construction waste, tailings, tunnel slag, etc. The manufactured machine sand is distinguished by rock type, and there are also differences in strength and use.
2. Abortion of machine sand production process:
The production process of machine sand includes: block stone → coarse crushing → medium crushing → fine crushing → screening → dust removal → mechanical sand. That is, in the sand making process, the massive rock is coarsely crushed by a jaw crusher. After the coarse crushing, it is sent to the impact crusher or cone crusher for further crushing. Then the material is delivered to the sand conveyor by a belt conveyor Further crushing is performed in the machine, and the finely crushed material is screened and dust-removed, and finally machined sand with a particle size of less than 4.75 mm is made.
3. Selection of machine sand equipment

Excellent production technology and reasonable equipment selection are the prerequisites to ensure quality. Shanghai Weili has accumulated more than ten years of experience in the field of machined sand production, and will continue to explore and design more quality machined sand production items for domestic and foreign customers.
