Introduction to Powerscreen and the 830 Trommel
Powerscreen, a prominent name in the heavy equipment industry, has been at the forefront of designing and manufacturing mobile screening and crushing equipment. Established in 1966, the company has consistently delivered innovative solutions tailored to the needs of the construction, mining, and recycling sectors. One of their notable machines is the Powerscreen 830 Trommel, a mobile screening unit renowned for its efficiency and versatility.
Design and Build
The Powerscreen 830 Trommel is engineered for optimal performance in various applications, including composting, topsoil processing, and recycling. Its robust design ensures durability and reliability in demanding environments.

• Dimensions: The trommel boasts a drum length of 9.2 meters and a diameter of 2.5 meters, providing a substantial screening area.
  
• Weight: The machine has a transport weight of approximately 33 tons, balancing stability and mobility.
  
• Transportability: With a transport length of 16 meters, width of 3.4 meters, and height of 4 meters, the 830 Trommel is designed for easy relocation between job sites.
  

Engine and Power System
The 830 Trommel is powered by a Deutz diesel engine, specifically the BF6L913 model, delivering around 130 horsepower. This engine choice ensures a balance between power and fuel efficiency, crucial for extended operations in remote locations.
Screening Capabilities
The heart of the trommel is its rotating drum, which facilitates the separation of materials based on size.

• Screen Area: The drum provides a screening area of approximately 51 square meters.
  
• Mesh Configuration: Equipped with 30 mesh panels measuring 380mm x 1,265mm, the trommel effectively separates materials into different grades.
  
• Cleaning Mechanism: Nylon brushes are integrated to clean the mesh, preventing blockages and ensuring consistent performance.
  

Conveying System
The 830 Trommel features a comprehensive conveying system to transport screened materials.

• Main Conveyor: A 1.5-meter wide conveyor transports the fines material from under the drum.
  
• Side Conveyor: Also 1.5 meters wide, this conveyor discharges oversize materials to a stockpile, with a maximum discharge height of 3.019 meters.
  
• Variable Speed Control: Both conveyors are equipped with variable speed controls, allowing operators to adjust the material flow as needed.
  

Hydraulic and Control Systems
Hydraulic systems play a pivotal role in the operation of the 830 Trommel.

• Hydraulic Jacking Legs: These facilitate rapid setup and leveling of the machine on uneven terrains.
  
• Load Sensing System: This system ensures optimal feed rates into the drum, enhancing screening efficiency.
  
• Diagnostic Controls: Onboard diagnostic systems monitor engine and hydraulic functions, providing real-time feedback and alerts to operators.
  

Applications
The versatility of the Powerscreen 830 Trommel makes it suitable for a wide range of applications:

• Topsoil Processing: Efficiently separates fine soil from larger debris.
  
• Composting: Screens organic materials to produce quality compost.
  
• Recycling: Sorts materials for recycling processes.
  
• Sand and Gravel: Separates different grades of sand and gravel for construction purposes.
  

Maintenance and Operational Tips
To ensure the longevity and optimal performance of the 830 Trommel, regular maintenance is essential.

• Regular Inspections: Periodically check the drum, conveyors, and hydraulic systems for wear and tear.
  
• Cleaning: Keep the mesh panels and brushes clean to prevent material buildup.
  
• Lubrication: Regularly lubricate moving parts to reduce friction and wear.
  

Conclusion
The Powerscreen 830 Trommel stands as a testament to Powerscreen's commitment to quality and innovation. Its robust design, coupled with advanced features, makes it a valuable asset for operations requiring efficient material screening. Whether in composting, recycling, or construction, the 830 Trommel delivers consistent performance, ensuring that operations run smoothly and efficiently.
