The Plastic Granulator Process

If you want to learn more, please visit our website Optima.

A plastic granulator breaks down plastic fragments into small pieces for recycling. There are several parts that go into making a plastic granulator, but perhaps the most important is the knife and the rotors.

The knife on the plastic granulator is usually mounted directly on the rotating rotor, or it&#;s on a stationary bed. There is a set of knives used to help break down the plastic. The exact space between the knives depends on the type of plastic you are processing and how. For example, if you have hard plastic materials, you&#;ll want to leave more space between the knives. Knives with a smaller space are better for a cleaner cut on soft plastics.

Knowing which type of knives you need is extremely important in deciding on what plastic granulator to purchase. For example, knives that have blunt tips are used for brittle materials most often. With softer materials, you&#;ll want knives with sharp edges to get more precision.

The rotor is another essential part of a plastic granulator. There are different types of rotors. For example, an open rotor is used for heat-sensitive resins because it allows for a healthy airflow while the material is being cut. A closed rotor doesn&#;t provide space between the knives and the shaft. You&#;d likely use a closed rotor if you need to cut thick materials, because this lack of space allows for more strength in the knives.

Understanding these different elements of a plastic granulator will help you determine which is the best for purchase in plastic processing.

· Jig Grinding Machine: This one is effectively carried out for grinding complex shapes with high accuracy and finish.

· Cylindrical Machine: Various work pieces with central axis of rotation usually uses cylindrical grinding machine

· Gear Cutting: Another machine which is commonly used for grinding is gear cutting machine. This can be effectively used for hobbing, machining, casting, forging and various other processes.

Material Processed

The purchasers of various grinding machines usually take into consideration the material which they wish to process right through these machines. Take the example; a gear cutting is usually used for metals, plastic and wood whereas belt grinding machine is used for metals.

Specifications of machine

With various different specifications, the manufacturers bring various grinding machine. Based on your requirement, you can get different specifications for different machines right from the machine suppliers. Some of the areas of these machines are

· Size of the grinding wheel which you are purchasing

· The input power which is given to operate the machine for various purposes

· Volt rating as well as frequency

· No load speed

· Control for the grinding head

· Horizontal or vertical spindle

· Lastly whether the machine is hand operated or CNC controlled machine.

Well buying the right grinding machine is surely not an easy task as there are lots of factors which should be kept in mind while you are purchasing the machine as mentioned above. A little research will surely help you to bring the right machine for your industry-specific purposes.
