Q: Q 1215040622
1, unique dual shaft design, independent cutting blade and gasket installed in the two parallel rotation axis, alternating overlap, spiral cutting, cutting effect is excellent. The blade and the gasket are made of alloy steel, which is uniform, high strength and high efficiency.
2, blade unique design, can crush rigid and flexible material. The motor is driven by a motor speed reducer to rotate, and the strong squeezing force and the shear force are generated. Low speed operation torque is big, the effect is good.
3, mechanical seal and framework oil seal assembly, no need to seal flush, adjust, easy to use and maintenance.
4, different amount of water, pipe type crusher head loss is small, circulation efficiency is good, the water flow is smooth.
5, when a blockage occurs, the control cabinet will issue instructions to the mill, the blade automatically reverses, the obstacle to withdraw from the re grinding, to achieve intelligent management, to meet the requirements of unattended.
6, the use of different gear configuration modular design, to meet the special requirements of users.
Application occasions
1, pipeline crusher is suitable for the vast majority of in-line equipment or pipeline applications, without the transformation of the pipeline or channel system;
2, installed in the pump station, sewage treatment plant imports;
3, this machine can crush the items are: paper products, wood products, plastic products, rubber products, domestic waste, etc..
4 product features
4.1 in the water to be broken, can not only protect the water treatment equipment, but also can avoid the leakage of odor, protect the environment.
4.2 broken performance is excellent, with overload protection function, safe and reliable operation, can be automatic control. If the crusher in the broken sewage solid waste generated overload, it will produce overload current, the electric control system will automatically action, break the opportunity to immediately reverse the moment, solid waste discharge, return to normal work.
4.3 installation and maintenanceSimple.
5 structure and working process
PG crusher is mainly composed of vertical crusher, pipe connection, electric control box and so on. Vertical crusher mainly consists of driving parts, driving shaft, driven shaft, milling cutter, mechanical seal, shell and so on. The drive unit drives the driving shaft to rotate and drive shaft by crushing machine, precision gear drives the driven shaft to rotate, which are fixed on the cutter shafts are reverse rotation, and the solid crushing bite.
