Rapidmix 600C Mobile Pugmill Mixing Plant

The RapidMix 600C twin-shaft continuous mixing plant is Volumetric (C).  RapidMix has been designed to be totally mobile and completely self-contained with its own power source. It is also completely self erecting, using the hydraulic system to change the plant from its travel mode into a fully operational plant in a few hours.  The RapidMix (C) Plants are volumetric continuous mixing systems.  When the ingredients of concrete are flowing continuously and measured by volume, by using a calibrated rotary opening, a calibrated fixed-gate opening, or a combination of these, so that a known, predetermined volume of each ingredient is obtained in a designated time interval, the method of measurement is volumetric. Continuous volumetric measurement with multiple ingredients requires that the proper relationship among those ingredients be maintained. It is this calibration of speed and volume which provides a smooth, continuous release of materials. The RapidMix 600C is capable of mixing up to 600 tons per hour depending on application.  Feed rates are fully adjustable for the aggregate, cement and water systems.  RapidMix twin-shaft continuous mixing plants are designed for any mixing application where a cement or binder needs to be mixed into a base material. Products such as Roller Compacted Concrete, Cement Treated Base, Bentonite, Contaminated Soil Stabilization and more can all be mixed in this machine.

Aggregate Hopper w/ Variable Speed Belt Feeder

  • Aggregate HopperCapacity: 15.6 cu yds (12.0 m3 )
  • Loading Width: 14 ft 2½ ins (4330 mm).  Can be loaded from either side of Hopper.
  • Construction: S275 plate with stiffening ribs. Steep sides for stubborn materials. (60-degree end slopes).
  • Removable Division Plate: Removable divider allows for two separate materials.
  • Lining: For a smooth discharge of the materials, surfaces are fitted with low friction high molecular polyethylene lining material 1/2” (12mm thickness).
  • Adjustable Gates: The outlet is fitted with adjustable gates to enable the material height and ratio on the conveyor belt to be adjusted manually.
  • Belt Feeder: The conveyor is fitted with a heavy-duty, automatic variable speed, 3 ply 1200mm (4’) belt at the bottom of the hopper to provide feed from the hopper to the mixer. Adjustable rubber skirts and heavy-duty support rollers are also provided.


Twin Shaft Continuous Mixer

  • Mixing Action: Twin adjustable 110 r.p.m shafts mix the material.
  • Paddles: Twin horizontal mixing shafts with 72 Ni-Hard cast paddles are intermeshed and phased to optimize mixing action and output.
  • Cleaning and Maintenance Access: Maximum access for maintenance and cleaning operations. The mixer is fitted with hinged access covers to give access to all of the mixing chamber. Hydraulic cylinders open both sides of the mixing chamber.
  • Drive: The shafts are driven by (2) 55 kW (75 HP) electric motors. A reduction gearbox with twin gears synchronize the shafts.
  • Mixing Chamber: A troughed conveyor under the mixer forms the bottom of the mixer. The mixing chamber is formed by fabricated sloped sides.
  • Water Addition: A Siemens flow meter controls 2 ball valve spray bars fitted into the top of the mixer. This allows the water to be added to the material as it progresses along the mixer.
  • Clean-out Conveyor: Mounted on the bottom of the mixer, forming the bottom of the mixing chamber. This design allows the bottom of the mixer to be easily cleaned out at the jobs completion.


RapidMix 600C Mobile Mixing Plant Cement Binder/Silo

  • Capacity: 48 US tons based on material being 1500 kg/m3 (93.64 lbs/ft3).  Up to 70 t.p.h. throughput.
  • Construction: Square silo. All welded box section S275 plate with stiffening ribs.
  • Access to Roof: Folding access ladder with safety cage. Fitted with double tubular handrail and kicking strip. Silo top access hatch.
  • Outlet: Flanged to accommodate the rotary valve paddle feeder. A shut-off plate is used to close the silo outlet to for maintenance.
  • Silo Venting: 20m2 Reverse Jet Filter with fan assistance and pressure relief valve.
  • Filling Pipes: (2) 4” (100mm) steel pipes with screwed end for fitting cam locks and other delivery hose fittings.
  • Level Indication:  Wam Torex rotating paddle style level indicators to control high and low level.


Out-Loading Conveyor

  • Function: Transports mixed material from mixer to the truck. The conveyor handles the maximum feed rate from the mixer. A gob hopper fitted to the top end of the conveyor allows some mixed material to be held until the next truck arrives for collection.
  • Construction: Boxed steel construction. Mounting brackets for rollers and pivot mechanism. The conveyor has a folding section for transportation.
  • Belt: 1000mm (39.4”) 3 ply belt with vulcanized joint and heavy duty top cover.
  • Drive: Motorized drum with rubber lagging.
  • Belt Scraper: Polyurethane blade pre-cleaner scraper. Mounted on the face of the head drum.
  • Belt Scale: A Ramsy belt scale is attached to the conveyor to monitor and control the feed rate and manage the output.
  • Gob Hopper: S275 plate. 1.5 cu. yd. capacity. Attached to top of conveyor with pneumatic discharge doors to prevent segregation.
