In the resource treatment process of waste refrigerators, materials pre-treated by the double-shaft shredder still require efficient crushing to achieve deep volume reduction and material dissociation, creating core conditions for subsequent sorting processes. In response to the technological requirements of the waste refrigerator dismantling line, ALVA Machinery has developed the heavy-duty horizontal crusher to meet the comprehensive demands of overseas markets for equipment stability, processing efficiency and compliance. This paper systematically analyzes the equipment's performance characteristics, core structural design, adaptation to overseas customer needs and application value, demonstrating the core role of the equipment in the field of waste refrigerator resource treatment.
After being processed by the double-shaft shredder, waste refrigerator materials still have the adhesion of multiple materials such as metal, plastic and foam, which directly affects the subsequent sorting purity and resource recovery value. Relying on the combined impact and shearing action of the high-speed rotor and hammerhead, the ALVA heavy-duty horizontal crusher performs deep crushing on the pre-treated materials, realizing the full dissociation of different materials, and completing the secondary volume reduction of materials at the same time, so that the material particle size meets the requirements of subsequent magnetic separation, eddy current separation and other processes.
The equipment optimizes the crushing logic according to the characteristics of waste refrigerator materials, which can effectively process multi-material mixed materials including steel shells, aluminum pipes, hard plastics, foam materials, etc., and avoid uneven crushing caused by differences in material hardness. For metal components, the equipment realizes plate crushing and pipe disassembly through impact; for plastic and foam materials, it completes volume reduction and separation through shearing, ensuring that all kinds of materials reach the ideal crushing state, and improving the material purity and recovery efficiency of subsequent sorting processes.
At the same time, the equipment has stable continuous operation performance, which can adapt to the large-scale processing rhythm of the dismantling line, maintain stable crushing efficiency under long-term high-load working conditions without obvious performance attenuation, and meet the continuous operation needs of large-scale overseas solid waste treatment projects.
