Vertical Shaft Impact (VSI) Sand Making Equipment, also known as VSI sand making plant, is a high-efficiency and low-energy consumption sand making plant with internationally advanced technology, developed according to the characteristics of stone materials. This sand making equipment’s performance plays an irreplaceable role among various ore fine crushing equipment, making it the most effective, practical and reliable crushing machine.
Ninon's VSI sand making plant is widely used for artificial sand making and aggregate production of metallic and non-metallic ores, cement, refractory materials, abrasives, glass raw materials, construction aggregates, artificial sand, river pebbles, mountain rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings and stone chips. The sand making equipment is also applied in the production of aggregates for highway surfaces, cushion materials, asphalt concrete and cement concrete, as well as fine crushing and coarse grinding of various metallurgical slags.
The VSI sand making plant is especially superior to other types of sand makers when processing medium-hard, extra-hard and abrasive materials such as silicon carbide, carborundum, sintered bauxite, magnesite, etc. When used together with hydraulic protection jaw crushers, the sand making equipment can handle various metallurgical slags. It is particularly ideal for manufacturing construction sand and road construction aggregates.
Working Principle
Materials enter the center of the high‑speed rotating rotor evenly through the material distributor. The thrower blades on the rotor eject materials at an extremely high velocity. During natural falling, the stones collide with the materials accelerated and ejected by the rotor, and then impact the material bed or impact plates inside the crushing chamber of the sand making plant. Materials are crushed through repeated collisions, impacts and friction within the chamber of the sand making equipment. Materials can also be fed directly into the high‑speed rotating rotor from the top of the VSI sand making plant. Under strong centrifugal force, they strike at high speed the target materials distributed around the rotor in an umbrella shape, resulting in high‑density crushing. After mutual impact, materials form a vortex between the rotor and the casing, leading to repeated impacts, friction and crushing. The crushed sand particles are sized via the bottom screen (on some models) or air classification. Qualified final products are then discharged continuously from the sand making equipment.
