Good Performance Artificial Sand Maker Artificial Sand Making Machine
The VSI is typically used after a primary or secondary crusher. This makes a VSI ideal for making sand and for making coarse and medium aggregates for concrete/asphalt production. The hot sale models of VSI sand making machines are VSI 7611, VSI 8518, VSI 9526, etc.
Product Features: Lower maintenance costs, longer service life of vulnerable parts, quicker adjustments
Input Size: 0-50mm
Capacity: 70-640TPH
Material: Granite, quartz, basalt, pebble, limestone, dolomite, etc.
Vertical-shaft Impact Crusher (also known as "Sand Maker") has two feed modes - "feed at center" and "feed at center & sides". As for the former mode "feed at center", materials at the feed hopper firstly pass through the central hole into the high-speed spinning rotor. In the rotor, materials are fully accelerated and thrown outwards from the launching port to collide with a part of materials that freely fall after rebound. Next, materials hit the surrounding vortex material liner (or the impact block) inside the vortex chamber together. In the chamber, materials are bounced to the top of crushing chamber firstly and then change their direction by moving downwards to form a material curtain with materials emitted from the runner of impeller. Finally, finished products are discharged from the bottom discharge opening. As for the latter mode "feed at center & sides", firstly, materials at the feed hopper pass through the circular hole. Then, materials are divided into two parts by the distributing tray. One part of materials enter the high-speed rotating impeller while the other part of materials fall from all sides of the tray. Materials in the impeller would be accelerated rapidly and thrown outwards at a high speed to collide with materials falling from all sides of the tray. Next, all materials hit the surrounding vortex material liner (or the impact block) inside the vortex chamber together. In the chamber, materials are bounced to the top of crushing chamber firstly and then change their direction by moving downwards to form a material curtain with materials emitted from the runner of impeller. Finally, finished products are discharged from the bottom discharge opening.
