The ALmix "Compact Series" Drum Mixers

The entire ALmix "Compact Series" is designed to meet the needs of the small - medium producer.  The emphasis is on affordability with minimum sacrifice in sophistication and the understanding that small should not mean light weight.  Like all drum mix plants, our "Compact Series" plants eliminate the need for hot screens, hot bins, weigh hopper, weigh bucket and pugmill found in batch type plants.  However, unlike other drum mix plants, ALmix "Compact Series" plants can also eliminate the need for separate cold feed bins, cold feed conveyor, and surge system.

ALmix "Compact Series I" plants include cold feed system, slinger type inlet conveyor and venturi type wet collector all mounted on a common frame with the drum mixer.  An optional drag conveyor with integral three ton slug feeder is also available.  The drag conveyor is transported with the drum frame on portable units.

ALmix "Compact Series II" plants do not include a frame mounted cold feed system.  They do include a slinger type inlet conveyor and a venturi type wet collector mounted on the drum frame.  A skid mounted baghouse may be utilized in lieu of the wet collector.  The drag conveyor with three ton slug feeder is also available on all "Series II" plants.

ALmix "Compact Series III" plants include a slinger type inlet conveyor and a baghouse mounted parallel to the drum mixer on a common frame.   The drag conveyor with three ton slug feeder is also available on all "Series III" plants.

CAPACITIES & POWER REQUIREMENTS

Capacities are from 40 TPH (36 MTPH) to 140 TPH (127 MTPH).  Standard motors and starters are for 3-phase, 60 Hz, 460 volt power.  Options for 3-phase, 50 Hz, 380 volt power are available.

The Model Number of all ALmix "Compact Series" Drum Mixers consists of the drum diameter in inches followed by the drum length in feet.  Thus, the Model 4822 includes a drum 48" (121.9mm) in diameter and 22' (6.7m) in length.  All "Compact Series" drums are constructed from 5/16" thick A-572 alloy steel plate to resist abrasion and warpage.  Drums are trunnion driven through shaft mounted reducers by electric motors.  The trunnions are machined and heat treated before being shrunk fit on to the trunnion shafts.  Each trunnion assembly includes two spherical type trunnion bearings bolted to heavy steel trunnion adjustment plates to eliminate trunnion bearing misalignment.  Thrust rollers are provided to insure the proper operating position of the drum assembly.

INLET CONVEYORS

All "Compact Series" plants feature a slinger type inlet conveyor driven by an electric motor through a shaft mounted speed reducer and V-belt drive.  This relatively high speed conveyor eliminates the plugging and heat loss associated with normal inlet chutes.  Inlet conveyors include 8" (203mm) diameter head and tail pulleys, 4" (102mm) diameter CEMA B idlers, screw take-up assembly, material receiving hopper, 2-ply belting with 1/8" top and 1/16" bottom (3.175mm and 1.59mm) covers and open mesh drive guard.

COMBUSTION SYSTEM

The appropriate model Hauck Starjet burner is furnished as standard equipment on "Compact Series" plants.  The Starjet burner eliminates the need for refractory lined combustion chambers and ignition tiles.  The Starjet is standardly equipped to burn diesel fuel but with the addition of optional equipment it may burn natural gas, liquid propane or preheated waste oils.  The burner assembly is furnished complete with control motor, micro-valve, oil and air piping, pilot and main flame scanners, turbo blower and fuel pump.

POLLUTION CONTROL SYSTEM

The "Compact Series" plants are furnished with either venturi type wet collection systems or baghouses.  Wet collectors are integrally mounted on the drum mixer frame and include all duct work, adjustable throat venturi section, dewatering separator, exhaust fan with drive and exhaust stack.  A standard fitted water pump with direct coupled drive is furnished skid mounted for remote location next to the settling pond.  Baghouses are furnished skid mounted on Series II plants or mounted on the drum frame on Series III plants.  Return dust systems include in-line blowers which return collected dust to the mixing process.

RECYCLING

Recycling packages are available either at time of initial purchase or they may be retrofitted to your existing ALmix "Compact Series" drum mixer.
