Can stones be beaten into sand for construction sites

May,30,2021

In recent years, the price of sand and gravel has risen in various places and the shortage of sand and gravel resources has caused serious illegal sand mining and abuse of inferior sand and gravel. It has stumped many people, so many areas have begun to promote machine-made sand. But machine-made sand is formed by crushing stones. Is this legal? The following will give you a detailed answer.

Can stones be beaten into sand for construction sites?

Yes, after the sand making machine is produced and processed, qualified engineering sand can be produced, and the various indexes of the processed sand meet the specifications of engineering sand. Machine-made sand has several advantages.

Advantage 1 Good product size

a. The sand made by the sand making machine has better results, the finished product has uniformly sized particles, few needles, and mostly cubes.

b. Compared with natural sand and gravel, this kind of sand has stronger permeability, does not need too much treatment, and can be used immediately in the harsh engineering sand industrial production nowadays.

Advantage 2 The source of raw materials is universal

a. It is convenient to get the raw materials, unlike pure natural sand, which is difficult to dig, and the grade does not meet the requirements.

b. The more common ores such as river pebbles, pebbles, dolomite, artificial quartz stone, iron ore, etc. can all be produced and processed into qualified engineering sand.

How to choose stone sand making machine?

Commonly used stone sand making machines include vertical shaft impact crusher, hammer crusher, and impact crusher. Soft stone-hammer crusher

The effect of crushing soft stones such as limestone is good, but crushing hard stones such as granite and river pebbles is more wasteful and the production cost will be higher.

Hard Rock- Vertical shaft impact crusher

The loss of this kind of stone sand making machine is not high, but the feeding size is smal. Generally, it needs to be equipped with a cone crusher or a fine jaw crusher for coarse crushing. Take everything soft and hard- Impact crusher This kind of sand making machine has a large input, generally about 10 cm. It can crush soft stones and hard stones. When crushing hard stones such as granite, it is more efficient than roller sand making machines and VSI sand maker, but not high yield as the hammer type sand making machine. summary

There are three points in choosing the applicable stone sand making equipment.

1. Decide according to the raw materials: Because each type of stone sand making machine has different models, the suitable crushed stones are also different, so you should choose according to your commonly used materials.

2. Choose according to the production site: general stone sand making machines and some crushers need to be installed on a solid cement base column. If you need to disassemble and transport frequently, you can choose a mobile sand making machine.

3. According to production capacity requirements: the hourly output benefits of stone sand making machine equipment under different models and specifications are different. Therefore, the appropriate stone sand making machine model should be selected according to the actual demand capacity of customers.
