Granular shape and grading are two important indicators to measure the quality of machine-made sand. Among the main sand making machines in the market, the VSI IMPACT CRUSHER has the best output granular shape.

Generally speaking, high quality machine-made sand is mostly cubic or similar to sphere, while inferior sand has many edges and corners and high needle-flake content, which will seriously affect the peaceability and compressive strength of concrete.

In addition to the material characteristics, the granular shape of machine-made sand also depends on the equipment. There are many types of sand making machines on the market, but according to the crushing principles, there are mainly two types: impacting and extruding.

The latter type such as roller crushers can only produce materials with many needles and flakes, which cannot meet the requirements of high-grade concrete. For ensuring the quality of finished products, the VSI impact crusher becomes the first choice.

Common equipment adopting the impact crushing principle includes hammer crusher and VSI impact crusher. In terms of applicable materials, hammer crusher is mostly used for medium-hard materials, while VSI impact crusher is suitable for medium-hard, hard and brittle materials.

In order to meet the sand making needs of different users, the VSI impact crusher by DSMAC Group is equipped with two types of crushing chambers: "Stone-on-Stone" and "Stone-on-iron". "Stone-on-iron" has high crushing efficiency, and "Stone-on-Stone" has high quality products. Besides, the VSI impact crusher is of simple structure and convenient operation, maintenance and installation; low working noise, low dust pollution; light weight, diverse installation methods, and movable type is available.
