RSMX The Cubicator and more VSI Rotor Centrifugal Crusher selective. reliable. powerful
BHS Rotor Centrifugal Crusher RSMX The BHS Rotor Centrifugal Crusher RSMX is suitable for all types of minerals, from soft to hard and from slightly to extremely abrasive. Patented twin-chamber rotor With over 30 years of experience BHS-Sonthofen is the specialist for vertical shaft crushers and impactors. Since 2001 the patented twin-chamber rotor represents a milestone in the further development of these machines. This type of rotor enables the size reduction of even en toughest and highly abrasive s. Cubical end products Each single particle of the is accelerated by centrifugal forces and precisely directed against the impact wall. Any random effects during material processing are systematically excluded. You obtain a final product of superior cubical shape. Selective size reduction As a result of the precisely directed impact the size reduction of any individual particle containing less resistant components than the rest will be achieved to a greater extent. This allows crushing of friable rock components in a targeted manner and, as a result, significantly enhancing the quality of the products, i.e. Los Angeles values, frost resistance. In case of ores or minerals with components of different hardness one of the components will be enriched in the final material. Wearing parts All load bearing parts of the machine are protected by easily replaceable wearing parts. The wear parts are made of materials that are optimized for their respective applications. Neither hardfacing nor storing a spare rotor is required. Plug and play Machine and drive of the BHS Rotor Centrifugal Crusher are completely mounted on one base frame, ready for installation. A large, hydraulically liftable cover, slewable by 360 degrees, gives easy access to the wearing parts. Lubrication The BHS Rotor Centrifugal Crusher comes with an automatic oil lubrication system with incorporated monitoring ing unit. This ensures safe and trouble-free operation. Anti-vibration mounting The rubber spring elements installed between base frame and machine absorb all vibrations of the crusher generated during operation, thus keeping them away from the supporting steel structure. An electronic vibration detector will shut off the crusher in case of any excessive vibrations. RSMX 2

BHS Rotor Centrifugal Crusher RSMX Inside view of the Rotor Centrifugal Crusher Applications with rock shelf configuration Production from rock or gravel of cubical shaped aggregates, track ballast and sand even from highly abrasive s such as: gravel, granite, porphyry, gneiss, graywacke, quartzite, cement clinker, glass Crushing of highly abrasive materials such as aluminium oxide, ferrosilicon, grinding materials Selective size reduction of slags from: steel mills or waste incinerating plants RSMX with rock shelf confi guration Applications with anvil ring configuration Production of cubical shaped aggregates and sand from medium-hard, moderately abrasive s such as: gravel, limestone, dolomite, diabase, basalt, andesite, broken bricks Selective crushing of, for example: nagelfluh and other rock deposits interspersed with soft portions, moderately abrasive slags, industrial minerals, mining overburden RSMX with anvil ring confi guration You get more versatility: The BHS Rotor Centrifugal Crusher can be operated either using a rock shelf or an anvil ring as impact wall. Depending on your requirements, this allows to further cut down on wear parts costs or to achieve a higher size reduction effect. The changeover from one configuration to another is accomplished any time in a matter of minutes. 4
for soft, medium-hard or hard rock Working principle The material to be crushed is fed centrally from the top into the rotor of the centrifugal crusher. Inside the rotor the material enters the amply dimensioned centrifugal chambers, that eliminate clogging and allow a high throughput rate. Inside the rotor the is highly accelerated and hurled to the outside. This energy input is optimally supported by the patented, new BHS Twin-Chamber Rotor design. Subsequently, each single particle impacts the stationary impact wall (anvil ring or rock shelf). There, the size reduction is effected by impact producing a highly cubical shaped particle. Benefits of the twin-chamber rotor: high throughput rate low risk of clogging precisely directed material acceleration reduced wear optimal energy utilization Working principle with anvil ring confi guration (top view) Minimized wear Wear in the BHS Rotor Centrifugal Crusher is reduced to a minimum. The patented twinchamber rotor is characterized by functional simplicity. Within the centrifugal chamber a rock shelf is formed serving as self protection against wear of the rotor. If harder rock is handled, we recommend to use the rock shelf as impact wall making use of the rock-on-rock principle. Hardfacing or even storing a spare rotor is not necessary. The crushing result in the BHS Rotor Centrifugal Crusher remains completely constant during the full lifetime of the wear parts - this also makes a significant advantage as compared to crushers using conventional crushing technologies.

Optional equipment Motors The motor drive power required for your particular application will be determined based on empirical values or crushing tests. You always get the right motor size. Lubrication In case of higher ambient temperatures and increased temperature of the feed material a lubrication oil system with adjusted cooling power can be provided. Supporting structure If the crusher shall be positioned independently we can offer a supporting steel structure, which is optimal for maintenance and absorbs vibrations generated during operation. Control system A separate control unit, if necessary also with frequency converter, can be offered to monitor the machine functions. This unit is only required if no computercontrolled central control system is available. Safety system The standard safety equipment of the crusher is in compliance with the EC machinery directives. By means of an additional key transfer system the handling of the safety measures necessary for maintenance and repair can be further facilitated. Wear components Depending on the wear behaviour of the we can choose from different types of centrifugal profiles. Thus, you always get the configuration that is best suited for your particular needs. Quick change system The anvil ring is available in two designs. If space conditions allow the attachment of a lifting tool, a quick change system can be provided for the anvil ring as an option. Otherwise, the anvil ring elements can also be replaced by hand. Air cannon In case the is extremely susceptible to caking, preparations can be made for installing an air cannon system to the crusher. 10
