Rotor centrifugal crusher 4 BHS Rotor Centrifugal Crusher The BHS rotor centrifugal crusher RSMX is used for crushing and shaping all types of minerals – soft or hard, moderately or extremely abrasive.

Generating valuable products Superior machine technology Production of high-quality cubical products Worldwide proven twin-chamber rotor 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 high impact stress results in a very high cubicity of the final product. With decades of experience, BHS-Sonthofen is the specialist for VSI crushers. The patented twin-chamber rotor is yet another milestone in the on-going development of the VSI principle. Plug and play Consistent quality of final...

Outstanding flexibility Depending on the input material and desired crushing results, the BHS rotor centrifugal crusher can be operated with either an anvil ring or a rock shelf as the impact wall. RSMX with anvil ring Typical applications with anvil ring » Production of cubical high-quality aggregates and sand from medium-hard, moderately abrasive input materials, such as gravel, limestone, dolomite, diabase, basalt, andesite, broken bricks, cement clinker etc. » Selective crushing of conglomerates, moderately abrasive slags, industrial minerals, mining overburden etc. » Recycling of...

RSMX with rock shelf Typical applications with rock shelf » Production of cubical high-quality aggregates and sand from highly abrasive input materials, such as gravel, granite, porphyry, gneiss, greywacke, quartzite etc. » Crushing of highly abrasive materials, such as aluminum oxide, ferrosilicon, abrasives, glass etc. » Selective crushing of slags from steel mills, waste incineration plants etc.

Functional principle The input material is fed from above into the center of the rotor centrifugal crusher. In the rotor, it is taken up by the two generously dimensioned centrifugal chambers. They eliminate the risk of clogging and allow high throughput rates. The input material is accelerated outward at high speed. This leads to an optimized impact on the fixed impact wall or rock shelf, resulting in a cubical particle shape.

Advantages of the twin-chamber rotor Compared with the multi-chamber design, less air is carried by the patented twin-chamber rotor. This has a positive effect on energy consumption, and the energy thus saved is available for higher throughput rates. Furthermore, the capacity ot the dedusting system can be reduced. The open design of the patented rotor with two chambers allows the maximum possible material outlet size (89° per side of the rotor). This significantly reduces the risk of clogging. In the BHS twin-chamber rotor, a material bed forms along the centrifugal chambers, resulting in...

Reinforced cover lining  In order to increase the service life, a cover with a reinforced lining can optionally be selected. Electro-hydraulic cover opening  For even faster opening of the machine cover for maintenance and inspection, an optional electro-hydraulic actuation mechanism is available. Quick-change system  To reduce the set-up time, the quick-change system can be used – space permitting – to exchange the complete anvil ring set with the support of a lifting device. Electrical terminal box  All the cabling can optionally be connected to a terminal box for easier installation....

Tests give certainty We operate an all-weather processing plant on our premises in Sonthofen. All our crushing machines are installed as production size machines in this facility. We can perform crushing tests with your input material. A variety of machine parameters can be intensively tested. This is followed by detailed evaluation of the data and a grain-size analysis which serve as the basis for the creation of an optimal machine configuration.

Technical data 15 www.bhs-sonthofen.com Performance data (standard designs) Type Rotor diameter x height Circumferential speed Drive power 1) Drive power bigger than 400 kW available on request as a twin drive. 2) The throughput rate depends on the circumferential speed of the rotor and the grading curve of the input material. 3) The input size depends on the type of rock, the circumferential speed of the rotor and the percentage of maximum particle size in the grading curve (screened through square mesh). Dimensions and weights (standard designs) Type 4) Weight for standard design without...
