Ensuring the longevity of your Single Shaft Shredder is crucial for maximizing its performance and efficiency in waste management and recycling operations. This blog post will explore six strategic ways to extend the lifespan of your shredding equipment, from routine maintenance to avoiding operational errors.
Shredders play a pivotal role in the recycling industry, especially when it comes to processing film and fiber waste. These machines not only enhance the efficiency of recycling processes but also significantly contribute to sustainability efforts. Let's delve into the various applications of shredders in recycling film and fiber, and their impact on our environment.
Plastic pelletizers are incredibly versatile machines used in the recycling and manufacturing industries to process various types of plastics. These machines convert plastic waste into small, uniform pellets that can be easily reused in new products. Below, we'll explore the most common types of plastics that can be effectively processed using a pelletizer.
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.
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.
Introduction
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.
Working Principle
- Feeding: 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.
