High production pugmill enters the market

When not required as a pugmill, the pughead can be removed and used as a 16-metre track conveyor that can be fed by a loader, crusher or screen. The design also offers the option to fit a two-deck screen box, giving flexibility in plant management and utilisation of capital compared with the single plant function of most pugmills.

The removal of the pughead is quick and simple, as is the case with the folding mechanism on the conveyor head and tail sections, to achieve transport mode. The hydraulic folding is designed so the hydraulic cylinder piston rods are fully protected when the machine is in operational mode.

The machine is transported with the pughead attached at a height of 3.5m, 2.3m wide, 13.1m long and a weight of almost 20 tonnes. It comes standard with a Cat C4.4, 75.5kW water-cooled engine and a dual power, diesel-electric option.

The IMS pugmill is fitted with a twin shaft spiral mixer for high production and anti-surging to produce high quality material blending for stabilising roadbase materials with the addition of water, cement and lime. It can also be used for blending at asphalt plants, cold emulsified asphalt mixing (cold mix) to roller-compacted concrete and flowable backfill.

The structure design is based on a track conveyor construction, with three latticed sections on the main conveyor. The tail section includes an 8m feed bin and the head section includes the conveyor drive, consisting of twin Sauer-Danfoss hydraulic motors coupled to a rubber-lagged drive pulley with variable speed.

The pughead dimensions are 2400mm long x 1360mm wide x 835mm deep, and the mixing augers are 1800mm long by 640mm in diameter, fitted with replaceable 500-grade paddle tips rotatable through 180 degrees to equalise wear.

The pugmill drive consists of a hydraulic piston motor directly coupled to a chain final drive, to give an auger speed of 100 rpm at a motor speed of 1850 rpm, producing up to 400 tonnes per hour. The water supply has its own water surge tank and control gauges to maintain consistent flow to the mixing chamber.

Cement and lime additives can be added by manual controlled auger from silos or a fully computer-controlled integrated system operating between the pugmill and silo. Crusher & Screen Sales can also offer mobile 55-tonne capacity cement silos and additional mobile feed product bins.
