What are the advantages and disadvantages of pebble sand production

Cobblestone is a very common mechanism of sand raw materials, with the decreasing amount of natural sand and the government's increasingly strict control of natural sand mining, the mechanism of sand has become a red investment project, that cobblestone sand what are the advantages and disadvantages?

Advantages of pebble sand:

1. Raw materials are abundant and unrestricted, with uniform materials and pure composition. Mineral composition and chemical composition is consistent, unlike natural sand so complex.

2. No need to mine and dig stone, can save a lot of work, short processing cycle, low investment cost, finished product three-dimensional, good grain shape, quality can be controlled.

3. The fineness modulus is controlled by people, which can be adjusted according to the needs through the adjustment process, such as coarse sand (above 0.5mm), medium sand (0.5-0.35mm), fine sand (0.35-0.25mm), etc.. This is the natural sand can not reach.

4. The particle size is usually curved. When concrete is bonded with other structures, the bonding degree is stronger, the actual effect of compressive strength is stronger, and the service life is longer.

Disadvantages of pebble mechanism sand:

Cobblestone mechanism sand particles are sharp, angular, rough, and most of the fineness modulus is greater than 3.0, and the particle gradation is slightly poor, resulting in poor concrete compatibility, and easy to appear in the appearance of concrete quality problems. This brings certain difficulties to the control of construction quality, but its shortcomings can be overcome by choosing the right equipment, reasonably utilizing the stone powder content in the sand, adjusting the sand rate, and choosing the right admixture.

The above is a simple introduction to the advantages and disadvantages of pebble sand making and matters related to the selection of equipment, if you are interested in a deeper understanding of this pebble sand making machine equipment, welcome to consult with us online for free at any time, here is a professional product manager real-time online for you to answer, 24 hours online.
