Plastic granulator machines are used to reduce large plastic waste into smaller pieces of uniform size, which can be used as material for other forms of plastic. They also help to recycle used plastics and cut down on environmental pollution. Most polymers must be pelletized before they can be melted into plastic injection machines to make finished products. There are two types of pelletizing systems: hot and cold. Hot pelletizing systems use thermal energy to melt and then solidify the polymers, while cold pelletizers use mechanical pressure to compress a heated pellet into a small enough shape to fit through a hole in a die head.
A plastic granulator machine has several major parts, each with its own role in the process of reducing and processing plastics to create new products. The main components are the plastic cutting/granulation system, the electrical/control system, and the mechanical systems. Each of these has its own role in making sure that the granulator functions correctly and safely.
The plastic granulator machine has a power transmission system that encompasses all of the machine parts that convert the electrical energy that is being fed into the machine into mechanical energy, and then transmits this mechanical energy to the plastic cutting/granulation systems. This system is responsible for converting the electric power into the rotating motion that the granulator uses to cut and shred the plastic.
It also helps to ensure that the granulator operates in a safe and stable manner, and that the rotating blades are not creating unnecessary friction or heat that could cause them to damage themselves. This system is also responsible for ensuring that the electrical system is delivering the proper amount of power to the motor that drives the blades.
While the electrical/control system is responsible for managing the overall operation of the machine, it can also be used to adjust how the granulator works, depending on what type of product the user wants to produce. For example, a user can change the speed at which the granulator is operating, which will affect how big or small the resulting granules will be. The blades themselves can be adjusted to have a staggered design that improves cutting efficiency.
The open source waste plastic granulator can be built and operated for less than $2000 in materials, and can convert post-consumer plastic waste and 3D printed parts into polymer feedstocks that can then be used in direct material extruder-based 3D printers. Its experimentally measured power consumption is a minor contribution to the overall embodied energy of distributed recycling, and its particle size distributions are appropriate for most recyclebots. The granulator is also quieter than many comparable industrial devices, such as a plastic shredder. This makes it an appropriate technology for community, library, maker space, or fab lab-based distributed recycling. The granulator can even be retrofitted to reduce its sound level during operation. This is important, because a noisy granulator can discourage people from using it. plastic granulator
