Questions about the BIVITEC

What are the advantages of using vibratory screens in material processing and sorting applications?

These screens offer efficient, customizable, and versatile solutions for material processing and sorting applications, providing high throughput capacity and minimal maintenance requirements. The BIVITEC is designed to handle the most difficult materials without any plugging, blinding, or damage to the equipment, helping to keep operations running smoothly.

How do vibratory screens improve efficiency and throughput compared to other screening methods?

Vibrating screens utilize high-frequency vibrations to ensure highly efficient particle separation. They can also be equipped with multiple screen decks, enabling simultaneous screening of various size fractions and processing larger volumes of material in a single pass.

To meet your specific requirements, you can customize your mesh size and scalping deck on the BIVITEC, and adjustable vibration amplitude and frequency settings allow operators to optimize the screening process.

What types of materials are typically processed using vibratory screens?

Vibratory screens are versatile and can process a wide range of materials across various industries. Some of the typical materials they’re used for include:

  • Aggregates and minerals: sand, gravel, crushed stone, coal, ag lime, and gold ore
  • Recycling materials: C&D waste, scrap metal, glass, plastics, auto shredder fluff, shredded tires, and roofing shingles
  • Biomass and wood products: compost, leafy materials, peat moss, and wood waste
  • Industrial materials: concrete, clay, and slag

How do you adjust the amplitude, frequency, and other parameters of a vibratory screen to optimize performance?

Amplitude refers to the distance the screen surface moves during one cycle of vibration. Higher amplitude can help in screening larger and heavier particles, while lower amplitude is better for finer particles and more-delicate materials.

Frequency refers to the number of vibration cycles per second (measured in Hertz). Higher frequency is generally used for finer materials, while lower frequency is better for coarser materials.

Other parameters that can be adjusted include the deck angle, screen tension, and feed rate. In order to test real-world applications, AEI Screens offers on-site testing of our equipment. We’ll work with you to find the right machine and settings for your application. Contact us for more information.

How do you maintain a vibrating screen?

These screens are built from rugged materials, so little maintenance is required. But to ensure safety, longevity, and optimal performance, it’s best to do routine inspections, lubrication, cleaning, tightening of loose components, and drive system and screen media maintenance. 

Keeping a maintenance log and continually monitoring performance involving throughput rates and separation efficiency helps in identifying potential problems before they lead to significant failures.

What are some key considerations for safety when operating vibratory screens?

The equipment should feature adequate machine guarding, easily accessible emergency stops, and well-functioning control systems. Regular safety inspections and strict adherence to lockout/tagout (LOTO) procedures are essential.

Operators and maintenance personnel should be equipped with appropriate personal protective equipment and properly trained. AEI Screens offers training for all of our equipment.
