What is the difference between machine sand and river sand

Machine sand is generated by professional machines and equipment to meet the standards of construction sand, can replace the natural sand sand, widely used in construction, roads, smelting and many other industries, in the sand and gravel demand continues to grow, while the natural sand mining is difficult and costly market background, by the sand and gravel people's favourite. So how is machine sand generated? What is the difference with river sand?

A. What are the raw materials for producing machine sand?

At present, there are more than 200 kinds of materials can generate machine sand, in which all kinds of stones account for a relatively large proportion of these stones are widely distributed, the number of large, very common, used to generate machine sand is very convenient, the mining cost is also lower.

1. Harder raw materials: granite, basalt, iron ore, river pebbles, marble, etc.

2. Softer raw materials: limestone, dolomite, gangue, quartzite, shale soil, etc.

In addition to stone, construction waste, tailings, coal gangue and other solid waste can also be used to generate machine sand, which can not only alleviate the shortage of natural sand, but also solve the pollution problems caused by these solid waste.

B. How to generate machine sand? Quickly understand the generation process.

Machine sand is generated through professional equipment for crushing, screening and sand making:

The material is sent into the jaw crusher by the feeder for coarse crushing, and then the crushed stone is sent into the cone crusher (hard material)/impact crusher (soft material) by the conveyor for medium and fine crushing, and the finely crushed crushed crushed stone will be sent to the vibrating screen for screening, and the screened granularity that meets the requirements of the production will be sent to the finished product stockpile, and the one that does not meet the requirements will be sent to the sand maker for sand crushing until it meets the requirements.

Supplementary: some users and friends will request to configure a sand washing machine, which can make the machine sand cleaner and better selling.

C. What is the difference between machine sand and river sand? How much is machine sand?

This is where many novice friends are confused, we analyse from the following points:

1.Material. Machine sand is a little less strong and durable, but bonding, compression resistance is better, long life; river sand is stronger, more durable, less bonding.

2. Appearance. Machine sand is angular and three-dimensional (can be shaped); river sand is rounded and smooth.

3. Granularity. The granularity of machine sand can be adjusted; the granularity of river sand is not adjustable.

4. Environmental protection. Machine sand can reduce the waste of resources, production equipment in line with environmental standards, more environmentally friendly; river sand is less environmentally friendly, will cause damage to the river, beach and other ecological environment.

5. Generation cycle. Machine sand has a variety of raw materials to choose from, the generation cycle is shorter; river sand formation period is long, the generation cycle is very long.

6. Production cost. The raw material cost of machine sand is low, and the overall production cost is low; river sand has many restrictions on mining, and the production cost is high.

The current market price of machine sand is basically the same as the price of river sand. And river sand, natural sand is getting less and less, machine sand instead of river sand, natural sand has been the general trend, so now generating machine sand profit is very considerable, the investment does not lose.
