Screen Replacement in Record Time!

Finedoor recently had to produce a replacement asphalt screen in record time for a client in Scotland. The new machine at Hillhouse Quarry, Troon was manufactured in just four weeks to replace a cracked machine that could have failed at any time.

Hillhouse Quarry owned by the Hillhouse Group is one of the largest independent whinstone quarries in mainland Scotland, producing a range of quality aggregates for use in coated stone and concrete to the highest specifications. Aggregate is of high density and low drying shrinkage.

Delivered in record time the machine supplied was a 5m x 1.8m - 3.5 deck asphalt screen which was designed to fit into the existing sub frame and to discharge into an existing screen chute manifold. With an operating angle of 10 degrees the machine has an alloy steel shaft for reliability and strength and incorporates two self aligning spherical roller bearings with oil bath lubrication.

Bearing lubrication can also be easily converted to pumped oil lubrication at a later date if required. Drive is by guarded V-belt off a spring loaded motor base, powered by a 22kW motor operating at 1475 rpm.

James Blanchard - Finedoor Commercial Director, commented "We pulled out all stops to ensure that Hillhouse Quarry had a replacement screen on site in the shortest time possible. Although not installed until approximately one month later when production schedules allowed they had the on-site guarantee in case of failure."

John McGregor, Quarry Manager at Hillhouse Quarry said, "Finedoor had supplied a replacement screen for the original Parker screen and recommended that we use the oil lubricated option it was decided that conventional greasing was our best option as our 1980 Parker plant is still running with its original screen. The new screen was delivered on time and installed efficiently over a long weekend to minimise disruption to our production."
