Rapid International USA Roller Compacted Concrete(RCC)/Continuous Mixing Plants or Pugmill Plants have been designed and developed to be a cost effective method for the high capacity production of Concrete or for any application where a cement or binder needs to be mixed into a base material.
Rapid International USA RCC/Continuous Mixing Plants /Pugmills are used by construction, civil, environmental and paving contractors around the world.
Rapid International USA RCC/Continuous Mixing Plants/Pugmills are SUITABLE FOR MANY DIFFERENT APPLICATIONS:
- Mixing roller compacted concrete (RCC) for pavement
- Cement Treated base (CTB) or Cement Stabilized Base for Road Construction
- Environmental soil contamination applications
- Soil stabilization
- Sludge Solidification for non-hazardous and hazardous waste
- Mine back fill
- Bentonite land fill sealing for lagoons and protective cell lining
- Dam construction and many other applications...

Both the Rapid Mix 400 and the Rapid Mix 600 C have been designed to be totally mobile and completely self-contained with their own power source. They are also completely self erecting, using the hydraulic system to change the plant from its travel mode into a fully operational plant within a few hours. Utilizing a continuous mixing system these plants mix from 400- 600 tons per hour depending on application. Feed rates are fully adjustable for the aggregate, cement and water systems. The 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, and Contaminated Soil Stabilization can all be mixed in these machine.
Features and Benefits of both the Rapid Mix 400 and the Rapid Mix 600C Models Include:
INCREASED PROFITS AND PRODUCTIVITY
- 400 – 600 tons per hour depending on model and application
- Feed rates are fully adjustable for the aggregate, cement and water systems
TRAVEL CHASSIS
- The chassis is lattice design for superior strength and is equipped
with tri-axle running gear and lighting system for full highway mobility.
GEN-SET TO PROVIDE ELECTRICAL POWER FOR ALL MACHINE FUNCTIONS
EASILY TRANSPORTED FROM JOB TO JOB
- The hydraulic system is used to level machine to the working position prior to erection.
The plant changes from travel mode to fully operational within 2-3 hours.
MINIMAL SET-UP REQUIRED
- Mobile, completely self-contained with its own power source

ON BOARD WATER STORAGE TANK
- The plant is equipped with an on-board water storage tank with a variable speed pump to provide water to the mixer.Tank capacity is 1750 litres (462 galls) and is complete with ball valve and all necessary pipe work.
- Two positive displacement pumps are fitted to supply 2 water bars within the mixer. Each spray bar has a ball valve to allow addition of water early in the mix, later in the mix or both together. A calibration point for accurate water weighing is also included.
VERTICAL CEMENT SILO
- Capable of storing 55 US tons (Capacity based on material being 93.64 lbs/ft3)
- A slide shut off plate is supplied to isolate the silo outlet for maintenance to the variable speed rotary valve
- A unique fold-up ladder is incorporated in the Silo design, complete with safety hoops. The silo has a pulse jet air filter, emergency pressure relief valve and anti over fill valve.
- The on-board air compressor provides air to the silo pulse jet dust collector and the air cylinder located on the truck load out gob hopper.
- A rotary valve is fitted to the outlet of the silo cone that meters material into the pugmill mixer at a consistent feed rate.

LOADING HOPPER
- The material loading hopper has step sides that are lined that are charged by wheel loader. The hopper is furnished with a belt feeder mounted at the outlet.
OUTLOADING CONVEYOR
- Mixed material can be held in the gob hopper which eliminates segregation of mixed material and enable trucks to move in and out when in continuous mode. A belt scale is incorporated approx. midway along the length of the conveyor.
- The conveyor belt has a polyurethane blade pre-cleaner mounted on the face of the head drum to prevent carry back on the return side of the belt.

|
 TWINSHAFT CONTINUOUS PUGMILL MIXER
- Mixing tools rotate on twin synchronized horizontal shafts causing a progressive motion of material mix and constant agitation. Strategically placed spray bars provide consistent material hydration. All mixing tools are manufactured using “chill cast” hard wearing steel.
- Mixing chamber is lined with high wear resistant rubber lining. Top and sides of the pugmill mixer can be opened to provide full maintenance access. A conveyor is used as the mixer floor, thus allowing easy cleanout.
|
 CONTROL PANEL
- Incorporating the most up-to-date technology. Control panel allows the operator to store, edit and retrieve up to 30 recipes for the proportioning of different materials.
- Displays the current production during manual/automatic operation and displays the speed of the in feeds should you be manual operation.
- The control is also provided with a printer for tickets or reports that may be needed.
