Effective classification and size reduction help maximise efficiency and throughput in the mineral processing industry. MechProTech, an OEM equipment manufacturer, provides advanced solutions to enhance these operations.
This article explores the function, design, and applications of two of MechProTech’s rotating classification products: the TITAN Rotating Barrel Screen and Barrel Breaker. These solutions optimise processes such as sizing, washing, dewatering, and reducing size in mineral processing plants.
Classification Equipment
Rotating barrel screens and rotating barrel breakers effectively prepare and classify minerals for further processing.
Rotating Barrel Screen:
This equipment is primarily used for classifying materials by size and is suitable for both dry and wet operations.
It can be employed for washing, desliming, and dewatering various ores and minerals.
The TITAN Rotating Barrel Screen, for example, offers capacities of up to 2000 t/h, making it ideal for large-scale mineral processing operations.
Rotating Barrel Breaker:
On the other hand, the barrel breaker is specifically designed for size reduction, breaking down larger mineral particles such as coal and separating debris.
The TITAN Barrel Breaker excels at achieving uniform particle size distribution with minimal fines through its advanced speed control.
General Functions of Rotating Barrel Screens
Rotating Barrel Screen from MechProTech is a versatile solution for various mineral processing applications.
Trommel Screen:
They can be designed with an integral dump bin, push feeders, or stand-alone on the heavy-duty structural base frame. The equipment can be designed for fixed foundations, semi-mobile skid bases, or self-driven track mounting.
Our screens include:
- A perforated plate
- A steel barrel
- A woven wire mesh (HC or S/S)
- Polyurethane Panels (Arched)
- Wedge-wired
- Cast screen panels
Features:
- The screen is driven by the chain & sprocket system, ensuring reliable operation even under heavy loads.
- It offers a full range of screening media options for the different materials and operational needs.
- Inlet cones are standard to facilitate feeding, while dust covers and outlet configurations are optional for enhanced adaptability.
How It Works:
- The screen rotates at an optimal speed, which can be adjusted between 16% and 32% of the critical speed. This is controlled by an installed Variable Speed Drive (VSD), allowing operators to fine-tune the performance according to the material being processed.
- As the screen rotates, materials are lifted and dropped, allowing smaller particles to pass through the screen while larger ones continue to be processed.
Benefits:
- The adjustable speed and customisable screening options provide high efficiency with minimal clogging.
- The equipment is designed to handle a variety of materials, from coal to other mineral ores, making it a flexible solution for many processing plants.
General Functions of Rotating Barrel Breakers
The TITAN Rotating Barrel Breaker focuses on breaking down large particles while minimising the production of fines, making it a typical choice for coal processing.
Features:
- The breaker includes lifter bars as a standard fitment, designed to lift and drop materials to achieve maximum impact for effective size reduction.
- The optimal speed range is between 30% and 35% of the critical speed, allowing precise control over the breaking process via a VSD (variable speed drive).
How It Works:
- As the barrel rotates, the lifter bars elevate the material to 60º to 75º (height), which is then released to achieve maximum impact at the bottom of the barrel. This method is highly effective in cracking and breaking materials along their natural grains.
- The breaker’s perforated screening plates separate debris and unwanted materials.
Benefits:
- Allows uniform particle size distribution
- Minimises the creation of fines
- Preserving valuable minerals for further processing
- The ability to adjust the speed and impact
MechProTech’s Rotating Barrel Screen
The TITAN Rotating Barrel Screen’s design and fitment are tailored for mineral processing environments.
Design:
The screen can be designed with:
- a tapered barrel,
- a cylindrical barrel inclined at a specific angle,
- or a cylindrical barrel with a spiral scroll bar.
Each design option is engineered to ensure constant material flow and minimum bed depth for effective screening.
Installation:
The equipment can be mounted on fixed foundations, semi-mobile skid bases, or self-driven track systems, providing flexibility in integrating into existing processing plants.
Add Additional features like:
- integral dump bins,
- push feeders,
- or stand-alone setups on heavy-duty structural base frames
Construction:
Built to withstand harsh processing conditions, the TITAN Rotating Barrel Screen ensures longevity and reliability in various applications.
MechProTech’s Rotating Barrel Breaker
The design and finish of the TITAN Rotating Barrel Breaker emphasise ease of use.
Construction:
The breaker’s design is constructed from mild steel, ensuring it can handle high-impact operations. Lifter bars and specially designed feed chutes enhance material breakdown by ensuring optimal material feed and impact.
Screening Plates:
The perforated screening plates are made from 25mm-thick mild steel, ensuring a large open area for debris removal without frequent maintenance.
Dust Covers:
The breaker from the fully enclosed dust covers, lessens dust buildup and maintains a clean operating environment, contributing to the equipment’s lifespan.
Applications of Rotating Barrel Screens and Breakers in Mineral Processing
Rotating Barrel Screens:
- They is used in coal, gold, or various other mineral processing plants where efficient sizing, washing, and dewatering are crucial.
- They can handle both abrasive and non-abrasive materials.
Rotating Barrel Breakers:
- They are effective in the coal industry, where consistent particle size and reducing fines is the priority.
- They are useful in the separation of debris and the preparation of a ore for further processing stages.
