～3mm, the thickness 0.04～1mm of plastic sheeting.Obviously, the gap of cutter is it cannot be guaranteed that the needs of cutting gap, processed
Plastics are generally sandwiched in moving knife and the gap of stationary knife, cause the course of processing neither complete cut, are not entirely to tear up, but
Mixed types such as " cut, tear up, pullling, compressing and rubbing against ".
The increase in the gap between moving knife and stationary knife, also makes to be mixed into the material among moving knife and the gap of stationary knife, produces huge
Expansive force and frictional force, and there is putty phenomenon.In order to solve this problem, relatively simple scheme is to increase motor power,
To overcome frictional force.Although putting into very big power, effect is unsatisfactory.As：The Nagano shredder of Korea S,
Power is 110kw, and average productive capacity is less than 400kg/h；And for example：The JAC shredder that TaiWan, China is manufactured, uses
300kw motor, average productive capacity is 800kg/h；Angstrom Wien shredder, using 110kw motor, average productive capacity is 500～
600kg/h.But, these equipment remain a need for frequent more allowing blade replacement, and putty phenomenon also fails to solve.
