Tongli scrap metal crusher for recycling from the design principle is fully considered the equipment maintenance convenience, to help improve efficiency and save cost. Spray system control dust, visual pollution is we crusher a prominent feature. It can produce water vapor to replace the crusher oxygen, reduce the safety hidden trouble. Specific humidity type dust removal system operation cost is low, and no of subsequent problems adhesive layer. This simple configuration make crusher crushing cavity don't need to install the air separator device, so that the production cost greatly reduced; Equipment accessories modular, parts simplification, ensure that every raw material inspection, warehousing, production, use more transparent, and the specific a device with what parts are basis can be checked for quality and after-sales service and so bring convenient; Equipment cost-effective, in line with the needs of China's national conditions, low cost, high efficiency, and low maintenance.
