The rotor centrifugal crusher type RSMX is a high performance crusher with vertical shaft (VSI) and is used for crushing and refining of mineral materials. It is suitable for all types of mineral materials, including highly abrasive feed materials and feed materials with a high hardness. Depending on its size, high throughput rates of 30 to 400t/h can be achieved.
Every single particle of the input material undergoes extreme acceleration due to the centrifugal force in the rotor and is hurled against the impact wall. The impact wall can either consist of an anvil ring or alternatively of a material bed. Clogging is avoided due to the generous dimensioning of the rotor and housing. The crushing results can be substantially controlled and optimized by selecting a suitable speed.
Every single particle of the input material undergoes extreme acceleration due to the centrifugal force in the rotor, which hurls the particles against the impact wall. It is possible to achieve a very high cubicity of the end product thanks to high impact stress.
The crushing results remain consistent even as wear and tear increases. Due to the nature of the system, random effects are prevented while material is being shredded. This is another feature that sets the BHS rotor centrifugal crusher apart from other conventional crushers.
Every single grain is subject to selective impact crushing. As a result, more brittle material is shredded to smaller sizes than other materials. This makes it possible to selectively crush brittle aggregate elements or damaged input material and significantly increase the quality of the end products (Los Angeles values, frost resistance). In the case of raw ores and industrial minerals composed of elements that vary in strength, the end product is enriched.
With decades of experience in the field, BHS-Sonthofen is the specialist for crushers with a vertical shaft (rotor crushers and VSIs). One of the milestones in the further development of this machine is the patented twin-chamber rotor.
All areas of the machine that are in contact with the crushing material are protected by wearing parts that are easy to exchange and made of materials that can be optimized for specific applications. This does away with the need for surfacing or keeping a second rotor in stock.
The rubber spring elements between the base frame and the machine absorb vibrations generated during operation and keep them away from the support structure. Excessive vibrations are registered by an electronic vibration monitor and cause the machine to be shut down.
The input material is supplied to the center of the rotor centrifugal crusher from above. Once in the rotor, the material enters the two large centrifugal chambers, which ensure blockage-free operation and high throughput rates.
Compared to the multi-chamber version, less air is transported in the patented twin-chamber rotor. This has a positive effect on power consumption. The energy saved here can then be used to increase throughput rates, and the dust removal system can be operated at reduced power.
A material bed forms along the centrifugal chambers in the BHS twin-chamber rotor to provide autogenous wear protection. Compared to conventional rotors, the number of wear parts that are required is reduced to a minimum.
To provide an alternative means of operation, the machine can be shipped with a PLC controller (including touch panel) and a frequency converter if required. This allows for autonomous operation and monitoring of the machines functions.

The centrifugal concentrator rotates at a high speed, generating a high G force, which can separate small gravity recovery gold (less than 50 microns), which was of previously unrecoverable with traditional mineral jigs, spiral separator, and gravity tables.In recent years, the application of centrifugal force has proved to be an effective technology for recovering fine and heavy minerals. The centrifugal force acting on the mineral particles can reach 50 times its own gravity, thus significantly increasing the sedimentation speed of the particles. As the intensity of the centrifugal force increases, the size of the particles that can be captured becomes finer.
The centrifugal concentrator can be used to recover the tailings of chromite, gold, scheelite and other heavy minerals, so as to make better use of mineral concentrates. Their operating and equipment costs are relatively low. Thanks to its less environmental impact and good recovery of fine-grained minerals, the application of centrifugal concentration has become increasingly important worldwide.
The gold centrifugal concentrator is a gravity-enhancing device. The feed slurry is introduced into a rotating drum, and the impeller rotates to form a high-gradient centrifugal field. The ore particles flow on the inner wall of the rotor and are continuously layered and deposited on the smooth inside the centrifuge wall.The lighter particles outside the bed are removed from the rotor assembly due to their lower specific gravity or smaller size. Heavy particles remain in the concentration zone, where the concentrate is cleaned with fluidized water.A rotor spins the bowl, which throws the feed coming into the center against the walls of the bowl. Light and fine particles are carried out of the bowl with the tailings while heavy and coarse particles are collected and removed from the bowl. Industrially they can operate as batch or continuous units, with pores opening intermittently to collect concentrate.
