Haver & Boecker introduce L-Class vibrating screen

Compact plant offers operational versatility and reduced maintenance for mineral producers

HAVER & Boecker have unveiled their L-Class vibrating screen for classifying wet/dry material and dewatering applications. The portable machine is said to be versatile and easy to maintain, with no timing belts or gears that normally need replacing.

Material producers can customize the 6ft wide screening unit in two lengths – 16ft or 20ft. Primarily mounted horizontally, the L-Class plant can also be inclined or declined by as much as 3°. The linear L-Class handles up to 400 tonnes/h and features a 45° mounted double-shaft overhead drive system with direct-mounted motors.

Producers can access multiple speed and stroke options by changing the pulleys and plate weights. The application-specific body design offers simplified maintenance with a single-piece removable head and shaft assembly. In addition, unlike most linear-stroke machines, the L-Class does not require timing belts or gears which helps to make maintenance even simpler.

The L-Class is also suitable for separating water from product in dewatering applications. When positioned at a negative incline of around 3°, the vibrating screen’s g-force moves wet material uphill on the screen.

Gravity and the natural operation of the equipment help screen out water before the material reaches the discharge end. The thick layer of material on the screen also acts as a filter cake and presses water out, and traps fine particles that would be lost in a thin-layer screening process.

For operations requiring a level of portability, Haver & Boecker engineers pair the L-Class with the Hydro-Clean 1000 wash plant on a skid structure.

The L-Class vibrating screens come with Haver & Boecker’s Uptime Service Package, which provides three-year warranty and a full-service approach to equipment optimization, from parts inspection and assessment to screen media evaluation.
