Plastic pvc crusher machine have long been an essential element of the plastic waste industry in our country. With more than 35 years of experience designing injection molding machine auxiliary equipment, Wensui Group boasts unparalleled expertise when it comes to designing pvc crushers. However, when considering recycling old plastics, what should we be mindful of?

1. Material Melting Point

The plastics industry boasts an expansive variety of plastic materials. Beyond the six popular kinds --PP, PET, PC, HDPE, PVC and PS --there are various modified plastics worth taking a closer look at.

Waste plastics introduced into a crushing chamber can reach speeds of over 520 RPM with multiple cuts performed by moving and fixed knives within the chamber, producing smaller than 12-millimeter granules for recycling while producing significant friction that produces heat.

When working with modified, standard or industrial plastics at high temperatures, their plastic can disintegrate, causing screen obstruction or, in extreme cases, modifications to its properties. This could result in screen obstruction or modifications of their properties altogether.

Wensui Group Protection's R&D team has developed an answer to address this problem through customer feedback and years of experience and knowledge. Utilizing melting points of products processed by customers as input for temperature control within crushing chambers. A heat dissipation pipe that directs cold water through interior walls reduces internal temperatures by dispersing excess heat more quickly during processing, thereby effectively solving excessive heat problems.

2.Dust Generation during Material Crushing

Dust is an ever-present issue in plastic-crushing industries, yet by regularly maintaining sharp knives, you can drastically decrease its production and reduce dust pollution.

What effect can sharpening knives have on dust production? Let's use an example as evidence: when used to crush a 10 cm x 10 cm chunk of plastic into 12mm-sized granules using an average knife, it might only require 10 passes through the chamber for crushing; on the contrary, an inferior blade might require up to 20 passes and cause additional friction, creating more dust production with each pass through the chamber.

Regular maintenance of equipment will lead to greater efficiency and output and can even reduce dust levels in products and equipment. Wensui Group Protection R&D team provides an innovative solution - pulse dust extraction ports on feed-hopper and fans collection hopper are used as dust extraction ports, providing effective dust removal methods capable of extracting up to 98% of dust for cleaner processing environments.
