Optimized Impeller Enhances Efficiency By 30% And Reduces Wear By 40%

Through systematic mechanical analysis and verification, SBM optimized the structures of impeller and vulnerable parts. Compared with the traditional sand makers, VSI5X Sand Maker obviously increases the material throughput and ratio of crushing, and enhances the working efficiency by 30%-60%. The wear costs of vulnerable parts reduce by more than 40%.

Hydraulic Device to Open the Cover Automatically Reduces Maintenance Costs

In consideration of the maintenance and part replacement during the production of the sand maker, SBM introduced semi-automatic hydraulic system. By only pressing a button, users can open the top cover of the machine to carry out following operations. So, this system greatly saves labor costs and enhances the service efficiency.

Split-Type Structure, Extended Service Life of Spare Parts

Based on the actual situations of production, we found that some spare parts like the periphery guard board and impact block always wear terribly at some specific points. So, to avoid this phenomenon, SBM adopts the split-type structure when designing quick-wear parts, which not only greatly extends service life of quick-wear parts, but also reduces their using costs a lot.

Brand New Feed Mode

In consideration that customers may have two production demands (i.e. sand making and shaping) which require the switch between central feeding and fall feeding, SBM made a brand new improved design on the material distributing tray so that users can easily switch the feed mode, shortening downtime for adjustments.

Digitalized Processing, Higher Precision

There are tens of lines of numerical controlling machine tools. Operations such as steel plates’ cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.

Sufficient Supply of Spare Parts, Worry-free Operation

SBM, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.

Working Principle

VSI5X 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.
