Rotor centrifugal crusher (RSMX)

Rotor centrifugal crusher (RSMX)

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 400 t/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.

Benefits at a glance:

•    Generating valuable end products
•    Targeted, selective crushing and improved cubicity
•    Globally proven twin-chamber rotor
•    Stress is applied to every single particle
•    Highly flexible operation with anvil ring or material bed
•    Unit ready for operation
•    Easy maintenance and high availability

Highlights

Generating valuable end products

Superior machine technology

Creating high-quality cubical products

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.

Consistent quality of end products

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.

Targeted, selective size reduction

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.

Globally proven twin-chamber rotor

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.

Unit ready for operation

The machine and drive train are assembled onto a base frame as a unit that is ready for installation. A large cover that can be raised hydraulically and pivoted by 360° allows unimpeded access.

Reliable greasing

The BHS rotor centrifugal crusher is supplied with a recirculating oil lubrication system that includes cooling and integrated monitoring. This allows for low-maintenance, reliable operation.

Easy maintenance and high availability

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.

Vibration absorption

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.
