Compared with the double-shaft shredder, which has a very high appearance rate in the disposal of solid waste resources, and the fine shredder, which is frequently used in the preparation of alternative fuels RDF/SRF, the pre-shredder is so low-profile. It works diligently in the first shredding process of the solid waste disposal production line for domestic waste, aged waste, garden waste, renovation waste, etc., and removes obstacles for the subsequent smooth crushing and fast sorting with its strong "body" and tough execution.
The strong "body" of the pre-shredder originates from:
The cutter box has been heat-treated to eliminate the pre-stress generated by welding and enhance the structural strength , which is not easy to be deformed in processing and use; the upper and lower cutter boxes are molded in one piece, which has strong integrality, high fit, and higher mechanical strength, and naturally operates more stably and reliably.
The strong execution of the pre-shredder originates from:
Regardless of the shredding difficulty of the materials entering the equipment, the hydraulic drive can independently adjust the rotational speed to obtain a reasonable torque force to realize the rapid shredding of materials; when encountering a one-time feed of more or more non-shredded materials into the jammed materials, the hydraulic drive of the equipment to frequent forward and reverse rotation of the material has a good adaptability, and will not cause damage to the motor and the equipment.
Special cutter design, the use of imported high wear-resistant alloy steel material, surface hardening treatment, can easily implement the large solid waste material tear (between the cutter head), shear (between the cutter head and comb plate), extrusion (cutter head edge) and other multiple shredding operations; cutter wear can be repaired many times to reduce production costs.
The safe and stable operation of the pre-shredder comes from:
The equipment can shred materials in both forward and reverse rotation. In order to avoid overloading, when the equipment reaches the limit pressure (the limit pressure can be adjusted), it can automatically rotate in the reverse direction to redistribute the materials and continue the smooth operation.
Intelligent system composed of PLC and HMI, with bearing automatic oil lubrication and no oil alarm function, bearing temperature monitoring, high temperature alarm, super-high temperature automatic shutdown protection function, motor overheating, overload protection function, unbreakable object alarm reminder function, and so on the powerful function of prevention.
Adhering to the principle of low-profile "machine", high-profile work, the pre-shredder has shown its self-worth in many solid waste disposal projects.
Unafraid of difficulties, solid and steady pre-shredder, deserves to be the most reliable solid waste disposal production line in the number one role!
