SAND REFINER is the dry type crusher for making sand for the first time in Japan.

SAND REFINER is not ordinary Horizonal Shaft Impact crusher. SAND REFINER was developed specifically for the manufacture of sand, so the manufacturing method of the sand is the same as the process when stones becomes sands in the natural world.



1.Manufacturing method of the sand

Manufacturing method of the sand by SAND REFINER has three processes.


Stones are crushed by hammers that rotate at high speed.


Stones are beaten with hammers will hit the wall of the crushing chamber. At this time, the stone will be crushed and grain shape improves (solid content after SAND REFINER : more than 58%) further with the collision to the specially designed breaker plates attached to the wall of the crushing chamber.


Stones crush with each other in the crushing chamber.

2.Product size distribution control

SAND REFINER is equipped with "rooster(grate bar type screen)" at the discharge part of the grinding product in the crushing chamber. Product size distribution can be controlled easily adjusting the clearance size between each bar of rooster.
Stones that are not able to passed through the clearance between each bar of rooster are crushed again in the crushing chamber. Therefore there is little loss of the production and you can achieve the production efficiency of approximately 90%.

Product size distribution control

In addition, you can raise precision of the size adjustment more by using the dust collector in coordination with the rotary speed of the hammer by using the inverter.

Because SAND REFINER can perform crushing and grain shape improves and size distribution control at the same time, the special air classifier is not required. So SAND REFINER is low cost and compact. As it do not need the complicated electric control, operation and maintenance are very easy.


1.The highest level anti-wear

Anti-wear is the highest level. Key components (hammers, breaker plates, etc..) are made of special anti wear material. So you will save running costs.

Hammers can be extended after wearing so production quality can be maintained always fine for long time without changing new hammer.


2.Easy Maintenance

Consumable parts are all small and light (for example, a breaker plate is less than 30kg) . You can do maintenance easily and safely.


Low noise, low vibration.
Because of dry type sand making crusher, you do not need water and there is no wastewater.By combining a dust collector, there is almost no scattering of dust.
