Magnum Series

Counterflow Drum-Mix Asphalt Plants

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.
