Crushing, disaggregating and separating materials TRANSFORMING

TRANSFORMING MATERIALS INTO VALUE The company BHS-Sonthofen, headquartered in Sonthofen, Germany, is an owner-operated group of companies in the field of machine and plant engineering. We offer technical solutions in the field of mechanical process engineering, with a focus on mixing, crushing, recycling and filtration. With over 300 employees and a number of subsidiaries, BHS-Sonthofen has a global presence. Over 100 years of experience in crushing technology We built our first crushers for the aggregates industry over 100 years ago. In addition to targeted crushing, this market...

BHS Rotorshredder The BHS Rotorshredder crushes, untangles and disaggregates materials. The crushing tools exert an intense stress on the input material through a combination of impact, punch and shear forces. This results in selective size reduction with the following special features: » Particle sizes are reduced in a targeted manner » Composite materials are separated » Hard and brittle materials undergo intense size reduction » Metals are separated and cleaned » Entangled materials are liberated

Simple tools The BHS Rotorshredder uses several rotating hammers flexibly attached to a vertical shaft one above the other. The tools are of a very simple and sturdy design. They do not need to be readjusted or sharpened. Rotorshredder of type 2018 during construction of an E-Scrap recycling plant. The BHS Rotorshredder is designed to disaggregate a broad range of input materials. The intensity and selectivity in processing the input material can be influenced and optimized by means of various machine parameters. The flexibility to be able to cope with changing requirements in the future...

Functional description Separation of harmful materials The patented BHS Rotorshredder consists of a cylindrical working chamber with a high-speed vertical shaft. Mounted one above the other on the shaft are pairs of overhung crushing tools. The tools are aligned horizontally and stabilized by centrifugal force. The flexible suspension of the tools on the shaft also serves the purpose of overload protection. The Rotorshredder can optionally be equipped with a flywheel for energy storage. The EU directive for E-Scrap recycling requires that certain components containing harmful substances are...

PROCESS STEPS 7 www.bhs-sonthofen.com Example of the crushing process with a refrigerator in the Rotorshredder The crushing ratio and the intensity of stress on the material can be variably adjusted via the speed, and the configuration of the tools and grid. Three machine sizes are available to accommodate various requirements, especially in terms of throughput and input material size. 2. During operation, the hammers are positioned horizontally and stabilized by centrifugal force. 3. The feed is crushed intensively when it reaches the impact chamber. 4. fter just a few seconds the...

GRID SEGMENTS FOR MATERIAL DISCHARGE 8 Patented slotted grid A distinctive feature of the Rotorshredder is the patented slotted grid in the large, double-walled doors. The interior of each door consists of grid segments with slots through which the crushed material automatically leaves the working chamber once it has reached the required particle size. Different types of grid segments can be used depending on the input material and requirement. Grid configuration with a large aperture at the bottom, e.g. for the separation of tangled input material. Grid configuration with small apertures...

Construction and assembly of a complete BHS recycling plant in France. The E-Scrap plant is equipped with a BHS Rotorshredder of type RS 2018. The Rotorshredder is enclosed for disaggregation of E-Scrap in the first recycling stage. The second major component of an E-Scrap recycling plant can be a BHS rotor impact mill of type RPMV 1113 for fully mechanized treatment of the 0-20 mm fine fraction in the second stage

Treatment plant for E-Scrap in Romania. The E-Scrap plant in Romania is centered on a Rotorshredder of type RS 2018.

INPUT MATERIAL Shredder light fraction Aluminum scrap

MATERIAL OUTPUT AFTER AUTOMATIC SORTING Non-ferrous metals Non-ferrous metals Pre-crushed aluminum Rubber fraction (from window profiles) Aluminum shaped into balls in the rotor impact mill (RPMV)

Tests give certainty We operate an all-weather, industrial-sized treatment plant on our premises in Sonthofen. All our crushing machines are installed in this facility. The crushed material can be separated into different categories using a sieve or overbelt magnet. Samples can be analyzed in further detail. We can perform treatment tests at our center using input material from prospective customers. A variety of machine parameters can be tested. A box feeder is available for large material quantities. Even large input appliances such as heavy washing machines can be processed. All test...
