The Industrial Plastic Granulator is the equipment for re-grinding or recycling waste plastics to the injection molding, blow molding or extrusion process. It is used for crushing and recycling plastic materials such as PU, PVC, PC, ABC or pipes, plates, and packaging materials. There are many designs of industrial plastic granulators for size reduction, granulation, recycling devices and accessories. Whatever your required capacities are, take 5 minutes to read this article and you will have a complete understanding.

Industrial Plastic Granulator is a machine that shreds plastic, making it more manageable and easier to recycle. It can be used for a variety of plastic and rubber materials such as plastic profiles, pipes, rods, silk threads, films, waste rubbers, and plastic products. Industrial Plastic Granulator Machine is commonly used to break down large pieces of waste into smaller pieces that are easier to handle when recycling them. The machine is composed of a feeding hopper, cutting device, eccentric roller and rotary knife. Moreover, the machine has a large capacity, so it can handle large amounts of waste plastic in one go.

The Plastic Granulator Machine works by using a blade to cut plastic into slices. The motor drives the blade rest shaft to make the rotating blade on the shaft rotate relatively against the machine's fixed blade, with the best cutting angle.Staggered rotating blades on the rest enable materials to drop inside under the squeezing, tearing and cutting action, thus crushing the materials.
Low-speed Granulator : Applied to crush plastic sprues and a few rejects for reuse instantly.
Central Granulator: Suitable for centralized crushing of all kinds of materials, such as wastes or rejected parts from injection molding, blow molding, or extrusion lines.
Roll-feed Granulator: Applicable to granulating and recycling plastic films. After being pressed roughly by a material scroll, films are sent to a cutting chamber to be cut into granules to reuse.
Blades or knives are the most important component of a plastic granulator. The blades are used to cut, crush and grind plastic materials into small particles. There are many different types of blades, each with different functions.
Teeth blade: Used for instant recycling of thick and long or tough sprues and crushing a few rejects finely.
Paddle blade:Used for cutting thin-walled shells and tubes, bottles, flakes, pipe materials, profiles, etc. It allows increased efficiency and reduced energy consumption. It is suitable for cutting thin flakes and parts inside the cutting chamber.
Staggered blade:Staggered rotating blade design can decentralize the working load when granulating to increase cutting efficiency, making it easy to grab the materials to be crushed. The staggered blade is suitable for processing hard shells and solid materials.

A plastics granulator shears and smashes scrap plastic to make granules for moulding. Heavy knives are bolted to a rotor turn at high speed, close to a fixed anvil. Plastic offcuts from pressed products are loaded into a small granulator beside the press. Larger quantities are brought to a large granulator.
While this guidance has not been updated to reflect current work health and safety legislation (the Health and Safety at Work Act and regulations), it may still contain relevant information and practices to keep workers and others healthy and safe.
Please read this guidance in conjunction with all relevant industry standards that apply to you as a PCBU. This guidance will be progressively reviewed and either updated, replaced with other guidance, or revoked.
Granules pass through a screen which limits their maximum size. Granules that fall through the screen are collected for moulding.
Contact with knives
Entanglement
Contact or impact from ejecting plastic
Dust
Fire & explosion
Noise
Slips, trips and falls
Entanglement from unexpected rotor movement (during maintenance, cleaning & repairs)
Collision between moving and fixed knives
Ear protection

Dust protection
Hazard
Contact with knives while handling rotors
Harm
Deep cuts or amputation
Controls
POWER the cutters from interlocked circuits to ensure they do not move until guards are closed.
ENSURE that the size and shape of the chutes prevents reach to the knives.
USE a paddle to push items into the chute.
CUT material (like plastic sheet) to a MAXIMUM length of 1.5 metres, to prevent entanglement.
NEVER stand on raised supports that increase the chance of reaching the cutters.
KEEP guard interlocks safely maintained.
Rotors are somewhat sluggish, revolving for several seconds after power is turned off. Operators can slip and make contact with sharp knife edges while handling rotors.
Hazard
Entanglement when feeding long lengths of material into chute
Harm
Hands and arms pulled into chute
Controls
REDUCE length of material for granulation to a maximum of 1.5 metres.
Hazard
Contact or impact from ejecting plastic
Harm
Cuts
Bruising
Controls
USE flexible curtains in the throat of the chute to minimise the chance of thrown items. Curtains MUST allow entry of items for granulation.
WEAR a face guard as protection from ejected items.
Items that contact the knives and are thrown back from the chute can be hazardous.
Hazard
Dust
Harm
Eye irritation or damage
Breathing problems, lung damage or cancer
Worsening of existing health problems
Controls
CONTAIN plastics dust as much as possible during granulation.
