VSI Crusher

VSI crusher, referred to as the VSI sand making machine, it is SBM the introduction of Germany advanced technology development and production, with the international advanced level of high-performance new sand making machine equipment, its performance in various ore fine crushing equipment plays a irreplaceable role. The series set in one of two kinds of crushing modes, and 720 hours of continuous operation without stopping the machine, sand making industry has become the mainstream of the latest equipment.

VSI crusher suitable for soft or medium hard and extremely hard materials crushing, plastic, widely used in river gravel, rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, the artificial stone chips sand. Water conservancy and hydropower applications engineering, highway, highways and railways, passenger line, bridges, airport runways, municipal engineering, high-rise building sand production and stone shaping.

VSI crusher features and technical advantages:

  • 1. The structure is simple and reasonable, low operating costs.
  • 2. crushing rate, energy saving.
  • 3. With crushing, coarse grinding function.
  • 4. The moisture content of materials subject to little effect, moisture content of up to about 8%.
  • 5. More suitable for crushing medium hard, especially hard materials.
  • 6. Excellent product shape, cubic, flakiness content is extremely low.
  • 7. impeller from the lining wear small, easy maintenance.
  • 8. Working noise below 75 db (db level).

VSI crusher working principle

Material from the top of the machine vertical fall within the high-speed rotation of the impeller, under the effect of high speed centrifugal force, and the other part of the umbrella in the form of diversion of materials around the impeller produces high-speed impact and crushing, the material after each impact, and turn the impeller between the housing material to form a vortex several times each impact, friction and grinding, through discharge from the bottom, forming a closed loop several times, controlled by the screening equipment to achieve the desired finished size.

VSI crusher has a "stone at stone" and "stone blacksmith" The two types of "stone at stone" type for very abrasive materials processing; "stone blacksmith" version for abrasive materials processing is not strong, "Stone blacksmith "type specific" stone at stone "type into the sand rate 10-20%.

Material from the top of the machine vertical fall within the high-speed rotation of the impeller, under the effect of high speed centrifugal force, and the other part of the umbrella in the form of diversion of materials around the impeller produces high-speed impact and crushing, the material after each impact, and turn the impeller between the housing material to form a vortex several times each impact, friction and grinding, through discharge from the bottom, forming a closed loop several times, controlled by the screening equipment to achieve the desired finished size.

Artificial sand production line process of the production line to 40mm the following example to introduce the raw material:

  • 0-40mm aggregate by hanging feeder, belt conveyor transported to the VSI crusher crushing, breaking out material impact on a floor shaker for screening;
  • Less than 3mm thickness of the powder material into the separator, were treated 0-0.075mm, 0.075-3mm and stone powder composition 3-5mm finished stockpiles;
  • Greater than 5mm material back VSI crusher crushed again, to form a closed loop. 3-5mm material may be part of a finished product according to the material requirements, some return to VSI crusher again crushed;
