What is VSI Sand Maker?
VSI Sand Maker, also known as Vertical Shaft Impact Crusher, is a mature high-efficiency sand making and stone shaping equipment with international advanced technology. Different from extrusion and hammer crushing equipment, it uses high-speed material impact kinetic energy to realize self-crushing and shaping. It solves the problems of poor grain shape, excessive powder and uneven gradation of traditional sand making machines.
This vertical sand maker can freely switch between stone-on-stone and stone-on-iron modes according to materials. Stone-on-stone is suitable for hard material shaping with ultra-low wear; stone-on-iron is suitable for high-yield sand making of medium-hard materials. Widely used in river pebble, granite, basalt, quartz stone and construction waste sand production, the finished manufactured sand fully meets high-end construction standards, becoming the preferred equipment for commercial sand plants and high-standard engineering projects.

How does a VSI Sand Maker work?
The VSI sand maker uses vertical shaft high-speed impact crushing principle. After materials enter the machine from the top feeding hopper, they are divided into two parts by the distributor: a small amount of materials fall into the impeller inner cavity, and most materials flow into the peripheral crushing cavity.
Under the high-speed rotation of the impeller, the internal materials are accelerated sharply and jetted out at high speed, violently impacting and crushing with the materials falling in the peripheral cavity. In stone-on-stone mode, materials collide and crush with each other, realizing pure shaping with ultra-low wear; in stone-on-iron mode, materials impact the wear-resistant lining plate for high-efficiency crushing and sand making. Qualified fine sand and aggregates are discharged through the bottom screen, and unqualified materials circulate back for secondary crushing, finally forming high-quality manufactured sand with uniform grain shape and reasonable gradation.
