Features of Our Pugmills

Pugmill Control

The pugmill control system uses a Siemens S7200 PLC to control all the plant functions for automatic control with manual backup):

Control Panel Manual option on control panel complete with manual rate meters which display and allow adjustment on the speed of the in feeds
Control panel allows the operator to store, edit and retrieve up to 30 recipes for the proportioning of different materials
Siemens MP277 touch screen panel has facility to archive production information such as current stock levels and production records
Displays speed of the in feeds during manual operation - 40 character per line thermal printer

Outloading Conveyors For Hire

We specialise in pugmill hire across Australia and can provide outloading conveyor services. Call CMA today for a pugmill with an outloading conveyor.

The Out-loading Conveyor transports the mixed material from the Twinshaft Mixer to the Truck:

Fitted with Gob Hopper allowing a holding gate for mixed material
Three ply-belt with heavy duty top cover and vulcanised joint: 800mm (31.5”)
Polyurethane blade pre-cleaner belt scraper mounted on the face of the head drum
Drive has motorised drum with rubber lagging

Twinshaft Continuous Mixers

The twin shafts mix the material, whilst moving the material toward the end of the mixer.

Twin Shaft Pugmill Mixer All mixing tools are manufactured using 'chill cast' hard wearing steel –

Full maintenance via top and side openings of the mixer
Shafts are driven by electric motors: 1 x 75kW (100HP)
Spray bars provide consistent material hydration
A conveyor is used as the mixer floor, thus allowing easy cleanout

Cement Binder Silo

All CMA machines have a genuine capacity/ output of 400 tons per hour. CMA pugmills also have 45-ton binder silos that are self-erecting, enabling stabilised material to be produced for floodways etc, eliminating the need to mobilise in-situ stabilisers, spreader trucks and additional work crews.

Cement Silo Capable of storing 54 US tons (50 tonnes) –

Shut-off slide valves close the silo outlet allowing maintenance to hopper below - Full galvanised folding access ladder with safety cage
Access hatch on top of the silo
24m2 Reverse Jet Filter with fan assistance. A pressure relief valve is fitted to protect the silo from over-pressurisation
Storage vessel for receiving cement/binder material from road tankers Level probes control and monitor silo filling and emptying

Cement Binder Weight Vessel

Holding vessel continuously weighs material:

4 No compression load cells monitor the contents of the hopper
Twin outlet screw conveyor discharges the cement or binder into the mixer
Feed rate is measured by recording rate of change in weight observed on the loadcells
Rubber connecting socks contain the material and enable weighing
4 slide valves allow efficient filling of hopper

Aggregate Hopper with Variable Speed Belt Feeder

Aggregate feeders, water pumps and cement feeders (if in use) are sequenced in start and stop mode to eliminate wet dry patch inconsistencies in the mix. Hopper receives the aggregates into the plant from a standard loading shovel.

Aggregate Hopper Capacity of 15.6 yds3 (12.0m3) & loading width of 14ft 2.5 ins (4330mm)

Hopper can be loaded from either side of the machine
Steep sides for difficult materials (end slopes of 60 degrees)
Removable division plate allows two materials to be used
Adjustable level gates enable the material height on the conveyor belt to be varied
Belt feeder provides feed from the hopper to the mixer
Belt width is 1200mm (4') and a heavy duty 3 ply belt is fitted
Conveyor fitted with heavy duty geared motor drive, adjustable rubber skirts and heavy duty support rollers
