Cast iron and pig iron wastes are important categories in the metal recycling industry, including waste cast iron pipes, pig iron castings, machine tool bases, cast iron cookware, industrial cast iron leftovers, and crushed cast iron slag. These materials are characterized by high hardness, strong brittleness and rigid texture, which cannot be effectively processed by ordinary shredding and shearing equipment. In addition, bulk cast iron materials have low utilization rates and inconvenient transportation. The cast iron crushing press is a special high-pressure crushing equipment independently developed for hard and brittle cast iron materials, focusing on the extrusion crushing and refinement of various waste pig iron and cast iron wastes, and serving as a dedicated core device for cast iron waste resource regeneration.
The cast iron crushing press adopts the high-pressure extrusion crushing principle. Driven by an ultra-high pressure hydraulic system, its heavy-duty rollers and crushing cavity squeeze and crush bulk and integral waste pig iron and cast iron materials into uniform granular and small block materials through static high-pressure extrusion and rolling. The crushing cavity is composed of thickened wear-resistant steel plates and alloy liners, featuring strong impact resistance and wear resistance, which is specially adapted to the high hardness and easy chipping characteristics of cast iron materials, ensuring stable operation without wear and deformation. Meanwhile, the equipment is fitted with a hydraulic automatic opening structure, enabling quick cavity opening for blockage cleaning, convenient inspection, maintenance and material clearing.
This equipment specially solves the processing difficulties of cast iron materials, perfectly adapting to various hard and brittle cast iron wastes such as waste cast iron mechanical parts, cast iron pipes, residual pig iron castings, casting slag, and waste cast iron kitchenware. Different from the high-speed impact crushing of ordinary crushers, it adopts low-speed and high-pressure extrusion operation, producing no large amounts of dust and uniform crushed materials without excessive powdering. It maximally retains the purity of cast iron materials to avoid resource loss, and the finished materials with controllable and uniform particle size can be directly used for remelting and regeneration processing.
In practical production, the cast iron crushing press has outstanding core values. First, exclusive adaptation to hard and brittle metals: it overcomes the difficulty of processing high-hardness cast iron materials with ordinary equipment and fills the gap in fine processing of cast iron wastes. Second, high material utilization rate: high-pressure extrusion crushing with controllable particle size produces regular finished products with few impurities and high purity, greatly improving the regeneration utilization rate and market price of cast iron. Third, environmentally friendly and low-consumption operation: low-speed operation achieves low noise and less dust; the closed cavity design prevents material splashing, fully complying with environmental protection production standards. Fourth, sturdy and durable with simple maintenance: the heavy steel structure body and long-service-life wear-resistant accessories, together with an automatic control system, enable simple operation without professional on-duty personnel.
At present, cast iron crushing presses are widely used in cast iron recycling processing plants, casting enterprise waste treatment centers, and industrial solid waste recycling enterprises. As the key equipment for the resource regeneration of pig iron and cast iron wastes, it effectively promotes the fine and efficient recycling of hard and brittle metal wastes and boosts the development of the metal circular economy.
