Traditional plastic crushing processing method

Grinding methods can be divided into three categories: dry, wet and semi-wet grinding. Among them, wet crushing and semi-wet crushing are classified and sorted at the same time of crushing. Dry pulverization is usually called pulverization. According to the different forms of external force, that is, energy consumption, dry crushing (hereinafter referred to as crushing) can be divided into mechanical crushing and non-mechanical crushing. Mechanical energy crushing is the use of crushing tools such as crusher tooth plate, hammer head and ball mill steel ball to crush solid waste. Non-mechanical energy crushing stage is a new method of crushing solid waste by using electric energy and thermal energy, such as low inkstone crushing, thermal crushing, low pressure crushing or ultrasonic crushing. Low density freezing crushing has been used to crush waste plastics and their products, waste rubber and its products, waste wires (plastics and rubber are searched) and so on. At present, the widely used crushing methods include impact crushing, shear crushing, extrusion crushing and friction crushing. In addition, there are special low slump crushing and wet crushing.
