VSI Vertical-shaft Sand Maker is commonly known as the impact crusher or aggregate shaper. VSI Sand Maker is the fourth generation of high-performance sand-making machine developed by SBM on the basis of introducing advanced German technologies about sand makers and analyzing domestic situations of mining industry. Taking VSI Sand Maker as the prototype, SBM has pushed out upgraded VSI5X Sand Maker and VSI6X Sand Maker successively.

Working Principle

VSI 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.

    Miner brings in partner for Tanzania nickel project

    Australian metals devel-oper IMX Resources in September agreed to a $60-million farm-in deal with global resources company MMG Exploration Holdings over the company’s Nachingwea project, which includes the Ntaka Hill nickel sulphide deposit, in Tanzania.The Ntaka Hill project, which is a potential openpit mine, is located about 250 km from the Port of Mtwara, Tanzania, and currently has a Joint Ore Reserves Committee-compliant measured and indicated resource of 120 000 t of contained nickel, as well as an inferred resource of 238000t of nickel at an average grade of 0.66% nickel.

    As The Term Suggests

    Many people do not know why the machine is named VSI Crusher. VSI means Vertical Shaft Impactor in which shaft and crushing chamber are in vertical position which is a latest crushing technology, which is more economical. As per the sketch material is fed centrally through feed tube comes on distribution cap where it is divided equally and distributed in opening parts of rotor. At the same time, the stone or material gets accelerated and thrown on rock shell where material is broken against cohesion force. These principles’ advantages are wear cost is very less; there is no change in product gradation. Even if wear parts wear outs product will have same gradation and shape. High production yield can be achieved with lower horse power requirement.

    Design Concept

    SBM VSI crusher range forms part of a comprehensive range of materials handling equipment including screening, washing, recycling, feeding, conveying and stockpiling solutions. Our aim is to help our customers achieve the success they desire. Three key things that will help us do this: they are, quite simply, service, excellence and innovation. We aim to service the hell out of our customers, be excellent in everything we do and provide innovative product technology. SBM will spare no effort to make contributions tosand crushing industry with our advanced technology and concept.

    Product Application

    SBM VSI Series vertical shaft impact crusher adopt Germany advanced technology, which on behalf of world’s leading standard. VSI series crushers are widely used in crushing nonmetal mine, concrete, fireproof material, abrasive filler, frit, construction aggregate, sand, metallurgy and so on. It is the indispensable machine in sand making industry and it is also the most ideal truing machine for mining and construction industries.

    Product Advantage

      • Large capacity, product sizeuniform

        The maximum throughput of up to 520 T/H, compared with the traditional equipment and under the same power, the yield increased by 30% and stable. The product of a cube, grain shape, reasonable distribution, fineness modulus can be adjusted, especially suitable for artificial system sand and stone plastic.

    The vulnerability of low energy consumption and long service life

    The optimal design of crushing cavity impact angle, friction material and wear resistant parts, directly reduces the equipment costs; with the German original thin oil lubrication station, completely solve the problem of the spindle bearings, bearing temperature is constant, the maintenance cycle and service life extension.

    • Easy operation, maintenance convenient

      Light weight of equipment, installation is diversiform, convenient operation, once the specific use, only need to tweak, can maximize its excellent performance; equipped with hydraulic cover opening device, the crushing cavity parts repair replacement is convenient, it can length maintenance cycle and life extension.

    • Advanced technology of energy saving

      The core components are selected well-known international brands, to ensure that the system low failure rate; low working noise, unique air circulation system, greatly reduced the efflux air, so it’s advantageous to environmental protection.

    Operational Principle

    When VSI Crusher working, the material fall into the hopper, the feeding hole into the high-speed rotation of the left wheel, was rapidly accelerated in the left wheel, the acceleration of up to tens of times the acceleration of gravity, then high speed from the left wheel injective, first of all to another part of the material and the rebound after free falling impact, then a shock to the material lining layer (stone a stone) or counter block (hot stone), bounce oblique impact to the top of the vortex chamber, and changes its direction of motion, deflection downward movement, and is emitted from the impeller material impact to form a continuous material curtain. In this way, a piece of material by crushing cavity two times to many times the chance of hitting, friction and grinding effect on eddy current. The crushed material is discharged.
