The BHS rotor impact mill is a high-performance crusher with a vertical shaft that addresses the needs of the recycling industry. The mill’s unique impeller rotor works together with a toothed anvil ring to subject the inserted material to severe mechanical stress. Material compounds are crushed and separated selectively, entangled materials are isolated, and brittle-hard materials are crushed very finely. At the same time, metals are shaped into balls and cleaned. Watch the video to find out how to optimally prepare shredder fractions for separation by disaggregating composite material and pelletizing metals with the RPMX rotor impact mill.
BHS offers an established and optimized process for metal recovery from fine fractions – die Feinaufbereitung.. This consists of pre-sorting and the key process step of shredding, which is performed by a rotor impact mill, easily accomplishing multiple challenging processing tasks at once. The process then moves on to the steps of sorting via screens, standard separation, as well as magnetic and eddy current separation. Each plant is individually adapted to the customer’s requirements due to the large variance of the input material.
The feed material is loaded into the top center of the machine. When it impacts the rotor, the material is accelerated towards the outside by means of centrifugal forces; there, the horseshoe-shaped hammers engage it and throw it against the anvil ring, In the milling gap, it is crushed as a result of the impact and shearing forces. The material leaves the rotor through the gap and falls down through two outlet chutes.
The material is selectively transported into the gap between the anvil ring and hammer from above by means of the rotor cover plate. In this way, the full height of the grinding gap is utilized, resulting in a longer retention time and a higher stress frequency. An intense ball shaping effect is achieved in combination with a high circumferential speed, a narrow grinding gap of 4 to 6 mm and a specially toothed anvil ring.
The RPMV is a rotor impact mill used in the recycling industry. The ball shaper, which has proven itself for many years in a wide range of applications in the recycling industry, sets a new standard with the RPMX. The RPMX rotor impact mill is a turbo-ball shaper. It is used in the reclamation of materials from fine fractions containing metal (such as stainless steel and cable strands) that had previously been considered difficult to process.
The RPMV has proven itself in separating composites, crushing brittle components and shaping metals into balls with particle sizes from 5 to 30 mm.
A higher circumferential speed and the considerably smaller grinding gap characterize the RPMX. This feature set makes it ideal for ball shaping and separating composite parts with particle sizes from 0 to 15 mm.
An electrohydraulic lid opener can be installed as an option to ensure quick opening of the machine lid for maintenance and inspection purposes.
If required, all electrical wiring can be bundled in a terminal box for easy installation.
In the event of high ambient temperatures or if the material to be processed is hot, a supplementary lubrication unit featuring a larger storage volume and stronger cooling power can be provided.
In order to reduce material deposits in the outlet area, the mill can be optionally equipped with air cannons.
The use of a crane is recommended when replacing wear parts.
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 machine’s functions. The PLC controller can also be used to operate additional system components, such as in-/outlets, a dust removal system, a sorting unit, etc.
To complement the machine, we offer standardized or customized steel add-on solutions such as supports, platforms, railings, and stairs.
We are also able to provide you with complete system solutions that include, for example: Steel construction, bunker and dosing technology, feeding and draining/discharging technology, classifying and separation technology, as well as dust removal systems. We plan the system design in accordance with your requirements and comprehensively coordinate the project with you.
