Stimulated by high demand, the price of sand and gravel in various places has continued to rise, followed by a "production boom", but before that, everyone needs to understand some issues to avoid being misled when purchasing equipment, for example, is machine-made sand the same as washed sand? What is the specific production process of the two types of sand?

 Is machine-made sand the same as washed sand?

It is different from the definition. Machine-made sand is a series of processes such as crushing and sieving. The particle size is less than 4.75mm. Washed sand refers to the sand in the river or the sand on the old river bed, which are separated into various grades and specifications through washing. The two have a lot of difference in appearance, application, and composition, as follows:

1. Because washed sand is mixed with small pebbles and fine sand, the edges and corners are relatively rounded under the long-term erosion of river water. While the edges and corners of machine-made sand are sharp rough.

2. The machine-made sand product can be processed into different particle sizes according to different technological requirements, which makes it easier to meet daily needs. The washed sand is mainly floodplain sedimentary sand, including medium-fine sand, medium-coarse sand, coarse sand, gravel layer, and gravel layer.

3. Machine-made sand is generally a selected raw material, with uniform and stable material, and the mineral composition and chemical composition are consistent with the raw material. The chemical composition of washed sand is more complex and will be affected by the region. However, it should be noted that in some areas, the machine-made sand that uses the wet sand making process is called water-washed sand. Because the finishing process is done by the sand washing machine, there is no objective answer to the question of whether machine-made sand is the same as water-washed sand, which need specific analysis.

Detailed explanation of the production process of machine-made sand and water-washed sand Machine-made sand production process

The raw materials are sent to the coarse crushing equipment by the feeder for preliminary crushing. Then they are transported by the conveyor to the medium and fine crushing equipment for secondary crushing, and then the large aggregates are screened by the vibrating screen to be processed by the sand making machine and screening machine. The final work is dust removal, powder selection or sand washing, and recycling.

Washing sand production process

The sand mined from the river is transported directly to the sand washing machine by the conveyor. After washing, dewatering, and recycling, it is the finished water washed sand. You can choose to use a vibrating screen to distinguish different particle sizes and then it will be transported to the stockpile. What are the machine-made sand and water-washed sand production equipment?

The machine-made sand production equipment corresponds to the process. The jaw crusher for coarse crushing, the cone crusher for medium and fine crushing, the sand making machine for sand making, etc. The commonly used equipment for washing sand is wheel sand washing machine and fine sand recovery machine, etc. Machine-made sand production equipment
