This energy-saving pelletizer, available in both single or double stage arrangement, comes standard with hydraulic-powered screen change to ensure there is no downtime throughout each operating session.

Introducere

Recycling tires is a significant challenge that requires specialized equipment designed to handle the tough, durable nature of waste rubber. With millions of tires discarded annually, the importance of efficient tire recycling cannot be overstated. Rumroo, a global leader in tire shredding technology, offers innovative solutions that not only make tire recycling easier but also maximize the value of the end products. In this article, we'll delve into how Rumroo's tire shredders are specifically designed to recycle tires and the unique advantages they offer.

Our PP / PE plastic film water-ring pelletizing system integrates the functions of crushing, compacting, plasticization, and pelletizing all in a single step. At the heart of this system is our highly efficient single screw extruder with advanced heat stabilization technologies resulting in superior quality pellets that help to enhance your bottom line.

In addition to pelletizing plastic films, this system can also be utilized for raffias, filaments, bags, woven bags, and re-pelletizing of densified materials. The final products produced by this pelletizing system are in the form of pellets or granules that can be directly used in production lines for film blowing, pipe extrusion, and plastics injection, etc.

Principiul de funcționare

• Hrănire: As a standard design, plastic scraps such as film and raffias are conveyed into the compacting room through a belt conveyor; to handle rolls’ scraps, a roll hauling-off device is an optional feeding method. The feeding speed of the conveyor belt or roll hauling-off is fully automatic based on how full the compactor’s room is. A metal detector can be integrated with the belt conveyor and can interlock with the control system to alert and halt the system in case metal is detected in the feeding section.





• Shredding and compacting: The rotary blades of the compactor will cut up incoming scraps. Frictional heating caused by high-speed rotary blades will heat and shrink the scraps just below their agglomerating point. Optimally designed guide structures compact the material and direct it into the extruder screw. It crushes, dries, and compacts the material, which enables a rapid and stable feeding from the compactor directly into the extruder.





• Plasticization and degassing: A specialized single screw extruder is applied to gently melt the pre-compacted material. The plastic scraps will be thoroughly melted and plasticized in the first stage extruder, and the plastic will be extruded by the second stage extruder. With a double-zone vacuum degassing system, volatiles such as low molecular compounds and moisture will be removed efficiently, making it especially suitable for heavily printed film and material with some water content.





• Melt filtration: Segmented filtering principle is used, with preliminary filtering in the first extruder and fine filtering in the second extruder, to reduce the frequency of changing filtering sieves. The requirements for the filter technology depend on the quality of the input material as well as the planned use of granules.





• Water-ring Pelletizing: Die-face water-ring pelletizing system is set as the standard granulating method. Advanced dewatering vibration sieve combined with horizontal-type centrifugal dewatering presents high-performance dried pellets.

Hard drive shredders offer a secure solution for data destruction, physically destroying drives and making recovery impossible. This article explores the advantages, working principles, and applications of hard drive shredders.

Industrial shredders are heavy-duty machines used to process large quantities of materials, reducing them to smaller sizes for disposal or further processing. They are essential in waste management, recycling, and various manufacturing processes. Industrial shredders can handle a wide range of materials, including paper, plastics, metal, textiles, rubber, and electronic waste. They are used in industries such as waste management, recycling, automotive, and manufacturing. The basic principle of an industrial shredder involves cutting, shearing, tearing, or compressing materials. The core components of an industrial shredder include a feeding mechanism, shredding chamber, cutting mechanism, discharge area, and control system. Industrial shredders have various applications, including recycling, waste reduction, manufacturing, and data destruction. They offer benefits such as increased efficiency, reduced environmental impact, and enhanced security. Industrial shredders play a crucial role in managing and recycling waste materials while supporting environmental sustainability and data security.
