Screw-Based Machine for Shredding Vulcanized Rubber

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a device for shredding or breaking down vulcanized elastomers (such as rubber materials) using a screw conveyor inside a housing. The system features a simple construction, including a cylindrical end on the screw and a stationary ring, which creates a gap through which the elastomer is forced out by the movement of the screw.

Use CasesContent extracted from patent full text and abstract with AI.

• Recycling rubber from used tires or industrial rubber waste
• Processing scrap elastomers for reuse in manufacturing
• Breaking down vulcanized rubber for producing rubber granulates
• Shredding rubber scraps in automotive or footwear production factories

BenefitsContent extracted from patent full text and abstract with AI.

• Simpler design compared to complex shredding machinery, making it cost-effective and easier to maintain
• Efficient processing of tough, vulcanized elastomers that are otherwise difficult to break down
• Facilitates recycling and sustainable use of rubber materials
• Reduces labor and energy usage due to its mechanical simplicity

Patent Abstract

The invention relates to devices for comminuting vulcanized elastomers with at least one conveyor screw coupled to a drive in a housing with a feed opening. The devices are distinguished in particular by their simple implementation. For this purpose, the end region of the conveyor screw pointing toward the outlet of the device is a cylinder. At least one stationary ring is arranged on this cylinder. Furthermore, at least one region of the ring is located in the housing, so that an outwardly open annular gap is present between the ring and the housing, and the elastomer is transported outward through the movement of the conveyor screw and the resulting relative motion through the annular gap.
