New blended screen media options announced from Haver & Boecker

The blended screen media approach offers improved efficiency by extending screen media life and minimising issues such as blinding and pegging. Haver & Boecker technicians work with producers, evaluating their applications, challenges and goals to customise screen media selection in a way that optimises screening. The manufacturer’s variety of screen media options helps ensure producers receive an option best suited for their material type and size.

Haver & Boecker showcased its blended screen media options during AGG1 2018 in Houston.

Before making recommendations, Haver & Boecker technicians examine and evaluate the operation’s screening challenges. This begins by examining discarded screen media for signs of wear and breakage. Technicians then evaluate the vibrating screen in operation, looking for indications of blinding and pegging as well as evaluating the quantity and characteristics of the specific material being screened. Based on the observations, technicians will recommend the ideal screen media for each phase of screening to minimise wear and maximise screening efficiency. By eliminating premature wear and screen media breakage, operations avoid the high costs associated with unscheduled screen change-outs and prevent contamination which could require costly rescreening.

Each phase of screening is matched with the ideal screen media to address the challenges of that phase from layered to basic to sharp. The recommended media styles which could range from polyurethane to rubber to metal or woven wire, help minimise wear and maximise productivity.

In many applications, operators look for greater wear life on the screen’s feed end – at the layered phase. This can be accomplished by installing a section of heavy duty screen media, such as Haver & Boecker’s Ty-Max, Ty-Dura or Ty-Plate. These media selections offer a reinforced design by incorporating polyurethane, rubber or metal plate to withstand high top sizes and abrasion.

In the middle of the deck, Ty-Wire tends to be a popular choice since it gives operators the ideal combination of wear life and open area where most screening – or basic screening – takes place.

Using woven wire or self-cleaning screen media at the discharge end – where sharp screening occurs – will provide maximum open area at the end of the deck to allow any remaining undersized particles to fall through and for near-sized material to pass, preventing contamination of the final product.

Haver & Boecker’s array of screen media options allow operations to choose a variety based on its top sizes and opening requirements. A blended screen media approach can incorporate the following solutions based on specific challenges:

  • Ty-Max: producers looking for high durability and strength in a hooked section choose Ty-Max. Haver & Boecker reinforces the polyurethane screen media with an internal wire grid as thick as 3/8 in.


  • Ty-Wire: Ty-Wire combines woven wire with an engineered composite to achieve open area closer to wire cloth, but with four to seven times longer wear life. Ty-Wire weighs less than woven wire, making it safer to handle and easier to install. It is an excellent hybrid product.
  • Ty-Deck: Ty-Deck modular polyurethane panels are available in multiple configurations for flat deck setups. Ty-Deck’s lightweight design eases installation and sectional deck replacements.
  • Haver & Boecker’s polyurethane screen media is manufactured out of Tyrethane, the manufacturer’s signature blend of polyurethane. Chemists developed Tyrethane to offer the best combination of open area and wear life for both wet and dry applications. Tyrethane is poured opencast, resulting in 1.5 - 2 times longer wear life than injection-molded products. In addition, open cast polyurethane permanently hardens when cured to maintain its chemical properties, so it resists wear and tear. Injection-molded screens can soften when the temperature rises during screening, resulting in shorter wear life.
