B Deep-rotor Vertical-shaft Sand Maker


Lower maintenance costs, longer service life of wearing parts, quicker adjustments

B Deep-rotor Vertical-shaft Sand Maker is a new generation of sand-making product with a variety of independent patent properties developed by ZENITH with the introduction of German technology and based on VSI Sand Maker series. B Deep-rotor Vertical-shaft Sand Maker combines three crushing modes into one and has become the core equipment in machine-made sand industry.

Materials:Granite, quartz, basalt, pebble, limestone, dolomite, etc.

Product Advantages


Compared with traditional sand makers, the material throughout and crushing ratio are increased by 30%-60%, and the cost of wearing part is reduced by more than 40%.

By the semi-automatic hydraulic system, users can open the top cover of the machine to carry out maintenance only by pressing a button, which reduces labor costs.

To solve problem of abrasion at certain points, ZENITH adopts the split-type structure when designing wearing parts, which greatly extends service life of wearing parts.

Considering the two requirements of sand making and shaping, which requires switch between the two feed modes, ZENITH made a new innovation on the material distributing tray.

Working Principle of B Deep-rotor Vertical-shaft Sand Maker


B Deep-rotor Vertical-shaft 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.
