Unlocking the Full Potential of Aluminum Recycling with Rumtoo’s Specialized Shredding Systems

Recycling aluminum is essential not only for its environmental benefits but also for its economic value. However, aluminum often comes combined with other materials like plastics, complicating the recycling process. Rumtoo’s aluminum shredders are expertly designed to tackle these challenges, making them a leading choice for industries involved in aluminum recycling. These shredders don't just cut; they liberate aluminum from other materials, allowing for effective separation and maximizing the recycling value.

An increasing number of PET bottle washing plants are being established to recover dirty, highly contaminated PET plastic bottles. Most of these plants typically sell the PET flakes they produce directly to PSF (polyester staple fiber) plants. Given the limited applications of PET flakes, many of our clients seek to expand their business by converting the clean PET flakes they generate into PET plastic pellets. Once PET is manufactured into pellets, they can be widely utilized in injection molding, profile production, plastic manufacturing such as the creation of plastic sheets, and much more.

Our advanced single-screw plastic pelletizing machines with Heat Wave Stabilization™ produce premium plastic pellets by providing uniform heat distribution throughout the entire barrel length. 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.

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.

Princip rada

• Hranjenje: 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.

Decoding the Crucial Tools in Recycling Operations

In the fast-paced world of recycling, where efficiency meets innovation, the spotlight often lands on two heavyweight champions: plastic granulators and plastic crushers. As the push for sustainability gains momentum, understanding the roles and differences of these devices is not just useful—it's essential. Let's break down what these machines do, why they're important, and how they differ.

The plastic granulator is essential in plastics processing. Selecting the right model ensures production efficiency and quality, but with many types and brands available, it can be challenging. This guide aims to help companies choose the most suitable plastic granulator for their needs.
