First of all, follow the editor to understand what the international mechanism sand standard is like?

       According to the national standard, all machine-made sand and mixed sand that have undergone soil removal treatment are collectively referred to as artificial sand. The specific definition of machine-made sand is the rock particles with a particle size of less than 4.75mm made by mechanical crushing and screening, but does not include soft rock and weathered rock particles.

       Artificial sand is basically medium-coarse sand, with a fineness modulus between 2.6 and 3.6. The particle size is stable and adjustable. It contains a certain amount of stone powder. Except for the increase in the sieve residue of 150m, the remaining sieve residues are mostly present. Triangular or rectangular cube with rough surface and sharp edges and corners. However, due to the different sources of production and processing of machine-made sand across the country, and the different equipment and processes for producing and processing machine-made sand, the type and gradation of machine-made sand produced may be very different. For example, some machine-made sand has more flake particles, and some The particle gradation of machine-made sand is large at the two ends and small in the middle, but as long as it can meet all the technical indicators of artificial sand in the national standard, it can be used in concrete and mortar. Artificial sand that cannot meet the technical requirements of the national standard cannot be used because the grain type and gradation of machine-made sand can be adjusted and improved. At this point, artificial sand is essentially different from natural sand. The mixing ratio of the mixed sand is random in the sand making, which reduces its above-mentioned characteristics.

       In an important period of industry transformation and upgrading, China Sand and Stone Equipment has been committed to promoting the sand and aggregate industry. If you want to achieve the success of the machine-made sand industry, you must choose the right high-quality sand and gravel equipment to produce products that meet international standards. The V6S series vertical shaft impact crusher launched by ZGM industry combines the functions of stone shaping and machine-made sand production. Brand new four-wheel design, higher material passing rate and larger output.

       The V6S series vertical shaft impact crusher absorbs many years of research and development experience and technical concepts. It adopts a new four-port impeller design structure and a special sealing structure to prevent oil leakage in the bearing cylinder. It has a new type of sand making and crushing equipment with a number of advanced technologies, which is energy-saving, long service life, wide application, etc., help Dashachang gradually move towards large-scale and centralized production to meet the country's requirements for environmental protection and production capacity. The working principle of "stone hitting stone" reduces equipment abrasion and has a longer service life. The most important thing is that the machine-made sand processed by V6S fully meets the strict export standards, helping customers realize the strategy of going to sea quickly.
