HPGR Stone Crusher

Product Introduction:

HPGRs are known as an emerging technology in the grinding process in the mining industry. Compared to conventional crushing processes, HPGRs consume less energy, which leads to lower operating costs and environmental impacts. Also, using HPGR leads to reduction of work index and ultimately reduction of energy consumption in downstream stages. Another advantage of this type of crushing is the increase of degree of liberation. Also, HPGR is used at the end of the concentrate line to increase the Blaine for the production of pellet feed.

Roller presses consist of two rotating rollers mounted on special bearings. By applying pressure to one of the rollers with the help of a hydraulic system, the pressure force increases by 40 to 60 times. This pressure is formed in the area between the rollers and leads to grinding. The rollers are fed by a silo and a feeder installed on top of it. The distinctive feature of the roller press machine manufactured by Araz Stone Crusher Company is that the rollers of the roller press are covered with segments. This has caused the device downtime to replace segments and costs to be reduced.

Technical Specifications:

Advantages:

* Reducing energy consumption by %40 compared to other HPGRs

* Short setup time

* Good grinding due to the flat surface of the rolls

* Having Segmented rolls, which leads to easy and quick replacement of the surface of the rollers.

* Blaine increase up to 350 units
