The Tyler F-Class Portable Plant from Haver & Boecker is one of the units being showcased at the CIM 2018 Convention in Vancouver this week. It easily manoeuvres between areas in mines and quarries and its advanced double eccentric shaft design and four-bearing technology maintain consistent performance under surge loads, preventing material contamination. The innovative split-bucket system simplifies maintenance and bearing changes, and an optional end-tension bottom deck eases screen media change-outs. It can be used for scaling as well as primary and secondary classifying in smaller and mid-sized mining operations.

A custom-built chassis holds the vibrating screen and periphery equipment, such as crushers or conveyers, to customise the plant for each operation. The portable plant’s hydraulic system allows setup in 30 minutes as it positions the screen at an optimal angle of 18-20 degrees. Using inclined screens such as the F-Class on mobile units is a real innovation as they are less prone to pegging & use gravity to reduce energy and horsepower requirements as well as giving increased capacity. Comparing the rate of travel between an inclined and a horizontal machine, at 45-50 ft per minute (and at a specific tonnage), a horizontal screen will experience diminished capacity due to a greater bed depth. Alternatively, on a 20 degree incline and at 70-75 ft per minute travel rate, an inclined screen will deliver up to 25% more capacity than a liner-stroke horizontal machine. Haver’s custom Portable Plant chassis combines an F-Class vibrating screen with crushers and conveyors. An optimal end-tension bottom deck is also available for easier maintenance and increased throughput. The F-Class also incorporates Haver & Boecker’s Ty-Rail quick-tensioning system, which cuts screen change-out times in half. The patented system decreases downtime and improves productivity.
