Centrifugal Tørretumsmaker – Rumtoo Maskin

Centrifugal dryers, often referred to as centrifugal dewatering machines, are essential in modern industrial processes, particularly in plastics recycling and pelletizing. These machines utilize centrifugal force to efficiently remove moisture from materials, ensuring optimal dryness for further processing. With components including a hopper, centrifugal chamber, discharge port, and electrical control system, they represent a reliable solution for post-wash dehydration in plastic materials.

Comprehensive Guide to Centrifugal Dryers

In the plastics recycling sector, centrifugal dryers play a critical role. Cleaned plastic parts are fed into a hopper and transported via an integrated screw conveyor to a centrifugal drying chamber. Here, high-speed rotation uses centrifugal force to expel moisture, lifting dried material to the outlet. This process is efficient, reliable, and integral to maintaining product quality.

This guide delves into the applications, mechanisms, and key considerations when selecting a centrifugal dryer, providing valuable insights for professionals in the plastics recycling industry.

Applications of Centrifugal Dryers

Centrifugal dryers are predominantly used in plastic recycling and pelletizing lines. They are often integrated with shredders, washers, and conveyors to achieve superior drying results across a variety of materials, including:

• Pipe profiles
• Plastic building materials
• Plastic granulation processes
• HDPE/LDPE fragments
• PET materials
• PVC fragments

Key Components of a Centrifugal Dryer

Feed Hopper

Constructed entirely from stainless steel, the hopper collects materials for drying. It is typically connected externally to a washing machine and internally to a screw conveyor for seamless material transfer.

Screw Conveyor

This component is crucial for transferring material from the hopper to the drying chamber. The conveyor features a stainless steel screen at its base to drain excess water during transfer, ensuring efficient moisture removal.

Elektrisk kontrolboks

Equipped with renowned brand components, the control box offers clear functionality and user-friendly operation. It includes alarm functions for various issues and motor overload protection, enhancing safety and reliability.

Motor/Reducer

Acting as the heart of the drying chamber, the motor and reducer provide the necessary power for the paddles. Sourced from reputable manufacturers, they ensure high power output and stable performance, supporting drying capacities from 700kg to 2000kg per hour.

Centrifugal Drying Chamber

Comprising a rotor and an upright stainless steel screen, the chamber facilitates high-speed rotation. Materials are agitated similar to a washing machine, effectively expelling moisture through the screen.

How Centrifugal Dryers Work

Centrifugal dryers operate on the principle of centrifugal force. Material enters the hopper and is conveyed by a screw to the drying chamber. Here, high-speed rotation forces moisture out through the screen, resulting in thoroughly dried material ready for further processing.

Advantages of Choosing a Centrifugal Dryer

• Pladsbesparelse: Vertical design minimizes footprint, ideal for facilities with limited space.
• High Drying Efficiency: Centrifugal force removes moisture more effectively than evaporation-based methods.
• Versatile Integration: Compatible with various upstream and downstream equipment, including washers and packaging systems.
• Omkostningseffektivitet: Durable construction and minimal maintenance requirements lead to long-term savings.

Key Considerations When Purchasing a Centrifugal Dryer

Material Size and Density

The physical characteristics of the material affect drying efficiency. Selecting the appropriate screen and machine configuration is vital for optimal performance.

Production Requirements

Ensure the dryer’s capacity aligns with your production line needs. Consider hourly throughput, installation space, and ease of maintenance.

Additional functionalities

Some models, like those combined with water pelletizers, offer integrated solutions for immediate drying post-processing. Discuss custom requirements with Rumtoo-maskine to enhance plant efficiency.

Byggematerialer

Choose from options like 201 stainless steel for general use or 304/316 stainless steel for corrosive environments, ensuring longevity and compatibility with your materials.

Overall System Integration

Evaluate how the dryer fits into your entire production system, including discharge placement and material suitability, to ensure seamless operation.

Material Options for Construction

Selecting the right material is crucial for durability and performance:

201 Stainless Steel

Offers good corrosion resistance for non-aggressive materials, providing an affordable solution for many applications.

304 Stainless Steel

A common choice with enhanced corrosion resistance, suitable for most industrial environments.

316 Rustfrit Stål

Ideal for highly corrosive materials, offering superior durability despite higher costs.
