COUNTERFLOW DRUM-MIXERSMAGNUM SERIES
The Cedarapids / Standard Havens Magnum series of portable and stationary counter-flow drum mixers was the original counter-flow drum mixer and has been proven over many decades.
The CMI Magnum range is available in capacities from 150 to 600 tons per hour and a recent extensive design review of this legacy product has resulted in many upgrades including new high efficiency drying and mixing flights in the Magnum drum.
The new CMI Magnum “Bullet” Super-Portable series has been designed with an emphasis on substantially reduced installation time to provide a market leading set up time within 2 days when combined with a portable self-erecting hot mix storage system.
The Magnum Bullet 150, 225 and 275 have been redesigned to accommodate the drum travelling on the chassis in its working position and incorporate manual jacks with large base plates to distribute the load with minimal foundation requirements.
As a result of their greater size and output the all new Magnum Bullet 300, 400, 500 & 600 units have hydraulic erect systems which provide unrivalled set up times. In addition, relocation of the axles to the opposite end of the drum chassis aids the positioning of the drum at its working height.
- Field proven counterflow technology
- 30% + RAP with low maintenance costs and a single shell design
- Tuneable performance provided by indexing slingers
- Longest mixing zone in the industry produces high quality material
- Super-Portable, Portable, Relocatable and Stationary configurations
- Magnum "Bullet" Super-Portable series have hydraulic erect systems which provide unrivalled set up times
FEATURES
- Specially designed flight arrangement begins with material intake distribution flights, which feed the aggregate drying flights
- The unique design of the combustion flights keeps material out of and away from the burner flame, allowing for complete combustion
- A patented reversible slinger allows simple calibration and varies the effective drying length of the drum enabling the most efficient performance
- The recycle inlet allows the introduction of processed, crushed and reclaimed pavement material
DRYING HEATING ZONE
Unique veiling flighting that allows full utilization of indexing slingers has been refined based on years of experience in counterflow drums and can be tuned to maximise efficiency in all applications.
COMBUSTION ZONE
The combustion zone of Magnum drums benefits from flights that hold dried material against the drum shell and allow any airborne VOC’s from the mixing zone to be passed through the intense burner flame, eliminating visible stack emissions.
MIXING ZONE
Magnum drums feature the longest mixing section in the industry and are equipped with CMI’s unique “castlelated” flights, resulting in the best mixing of any counterflow drum.
INDEXING SLINGER
Indexing slingers on all Magnum drums (manual on Super Portable drums) allow the most efficient drying and heating by varying the point at which aggregate veiling begins.
MAGNUM “BULLET” SUPER-PORTABLES
The Magnum “Bullet” Super-Portable series have been designed for high mobility and rapid set up time with manual jacks on the smaller models in the range (larger models feature hydraulic erect systems) and large base plates to distribute the load with minimal foundations, providing unrivalled set up times.
SUPER-PORTABLE BULLET SERIES
AGGREGATE FEED UNIT
The optional portable aggregate feed unit with integral scalping screen and slinger conveyor enable fast site setup and relocation with minimal foundations.
AGGREGATE WEIGH FEEDER
Available in portable and stationary configurations, conveyors feature direct drives and a weigh conveyor idler belt scale with a pneumatically operated test weight facility. All portable conveyors are hydraulic self-erect and designed to carry screens onboard for transport.
DRUM
The combustion zone of Magnum drums benefits from flights that hold dried material against the drum shell and allow any airborne VOC’s from the mixing zone to be passed through the intense burner flame, eliminating visible stack emissions.
BAG FILTER
The Roto-Aire® Series of portable bag filters’ feature a unique cleaning system of reverse air flow through the bag, causing the bag to expand, providing a less aggressive cleaning approach resulting in longer life and reduced maintenance.
HOT MIX STORAGE
The SE Series of self erecting hot mix storage silos with integrated compressor, heated discharge gates and dual chain drag slat with various drive options, offer rapid site set-up on minimal foundations using their onboard hydraulic erect system.
AC STORAGE TANK
CMI's range of portable AC storage tanks are of a unitized design with pump package located at the front or rear of the tank for on-site versatility and quick set-up, while 4” thick high-density mineral wool insulation provides efficient heat retention.
RAP FEEDER
CMI offer a range of portable recycle feed bins, featuring landing jacks and conveyor self-erect system and can be configured with one or two hoppers, sizers, weigh scale, breakers and air cannon.
CONTROL HOUSE
The operator's control room features all round glazing providing excellent operational visibility. The motor control room houses electrical panels built to UL approval with branded components. Each room has its own independent air conditioning.
