AGGREGATE HOPPER WITH VARIABLE SPEED BELT FEEDER

The hopper has a capacity of 15.6 cu yds (12.00 cu m) and is 14 ft 2½ ins (4330 mm) on the loading side. It is so constructed having a removable division plate allowing two different materials to be mixed. In this mode the split hopper is loaded from both sides of the machine. The bottom outlet is flanged to suit the connection of the variable speed belt feeder. The hopper sides have very steep angles with side slopes of 60 degrees and end slopes of 60 degrees. The hopper sloped sides are fitted with low friction high molecular polyethylene lining ½ " (12 mm) thick. Manually operated adjusting slide gates are fitted at the exit end of the hopper to give additional variance to the feed rate. A conveyor belt feeder with variable speed control is fitted under the aggregate bin discharge point.

TWIN SHAFT CONTINUOUS MIXER

The twin shaft continuous mixer is fitted with paddles which are intermeshed in a special phased relationship to optimise mixing and maximise throughput. The shafts are driven by a 75 kw (100 hp) electric motor through a set of bull gears which run in an oil bath.

The mixing chamber is formed by fabricated sloped sides with a troughed conveyor under the mixer forming the bottom of the mixer. This conveyor is fitted with a high torque slow speed drive with a 5.5 kw (7.5 hp) motor and shaft mounted speed reducing gearbox. The driven conveyor drum is crowned and lagged and is 300 mm (12") diameter. This conveyor is used for clean out purposes only. The mixer should be lined with a bed of material every morning before production starts. This ensures easy clean out.
