Crushing Capacity
The capacity of a plastic shredding machine is influenced by several factors. One of them is the inner chamber size. The size of the crusher is determined by the inner chamber. Generally, the width of the crusher's inner chamber ranges from 80 to 150 cm. A wider crusher usually means higher output.
The speed of the crusher pulley also affects the capacity. The speed of the pulley on the crusher is calculated by multiplying the motor speed by the diameter of the small pulley next to it and then dividing by the diameter of the pulley on the crusher. Within the reasonable range of 400 to 800 rpm, a higher speed generally leads to higher output. However, if the speed is too low, the machine may jam, and if it is too high, the machine may vibrate.
The design of screens and blades is another crucial factor. The size of the crushed material is controlled by the mesh size of the screen. For example, the mesh size of pet bottle flakes is usually adjusted to 16 - 18 mm, while that of pvc plastic steel is around 30 mm. Thicker blade thickness and a smaller gap between the blades are beneficial. For example, some efficient shredder blades are about 10 - 30 mm thick, and the gap is usually between 0.2 and 1 mm, which helps increase the output of the shredder and improve plastic recycling efficiency.
Operation and Maintenance
When it comes to operation, choosing a plastic shredder with a high degree of automation can significantly save labor costs.
Maintenance is also an important consideration. It is advisable to choose a crusher that is easy to maintain and has low maintenance costs. For example, some crushers use blades made of 60 si 2 mn, which are durable and resistant to corrosion, thus extending the service life of the machine. Additionally, some manufacturers provide a one - year warranty, which gives strong repair assurance.
In conclusion, choosing the right plastic shredder is of great significance to the entire plastic recycling process. It is necessary to comprehensively consider factors such as equipment type, crushing capacity, operation, and maintenance to make the most suitable choice.
