For plastics waste shredding to the small output fraction about 8-50mm are used single-shaft shredders series DRJ. The main advantage of this machines is processing of heavy, tough and unshapely plastic wastes. Another advantage is required output size attained in one degree of shredding.
Single-shaft shredders series DRJ – the principal is cutting of the wasting material between cutting edges fixed on rotation rotor and fixed stator blades in the shape of rack. Voluminous and shapeless waste is pushed to the rotor by hydraulic pressure. This leads to gradual cutting of the layer of the shredded material. There is an exchangeable sieve which defines the size of output fraction by its holes installed under the working area of the shredder. The chosen size of the hole in sieve also significantly determines the hourly capacity of the shredding.
