| Drum Mixers: |

|
| ALmix’s parallel flow designs include
a special herringbone bolt-in flight design for maximum drying
and mixing efficiency, lower stack temperatures and reduced
fuel consumption. Drum mixers are constructed from 5/16" thick
steel plate and 3/8" thick A-572 alloy steel plate, depending
on the size of the drum. The drum is trunnion driven through
four (4) shaft mounted reducers by two (2) 15 H.P., 3/50/380v
motors. The main frame features unitized construction from
heavy, structural steel members with beams supporting the trunnions
and drum. Four (4) 12" diameter x 5" (or larger)
face trunnions are machined and heat treated to 500 Brinell
and are fitted with 2-15/16" diameter spherical type roller
bearings. Each trunnion assembly is mounted on a 1" thick
steel plate allowing the assembly to be adjusted as a unit.
The trunnions drive two 2" thick x 4" face 1045 steel
tires made from one piece forgings. The drum shell is reinforced
by 1/4" thick steel bands in the area where the tires
are wedged to the shell. Two 12" diameter guide rollers
are provided to insure the proper operating position of the
drum mixer assembly. The drum is mounted at operating slope
on the main frame, eliminating the need for costly elevation
on setup. Material is discharged from the drum by bolt-on abrasion
resistant steel sweeper flights through a side discharge chute.
An air seal constructed from high temperature belting is installed
between the drum and the discharge breeching. |
