Twin-shaft mixers are ideal for roller-compacted compacted concrete jobs, with the ability to mix even high-paste mixes within 45 seconds. These mixers are available in two sizes and are driven by one or two electric motors. Gears are mounted directly onto the counter-rotating shafts, saving space.

The Incite fiber doser processes most fiber types via conveyor belt, or directly into a mixer truck or central mixer. A removable tray allows rapid changeover of fiber compositions with dispensing capabilities for polypropylene, glass, fiberglass, or steel. The filling capacity ranges from 500 to 3000 kg. An optional container system allows the unit to be used in multiple locations. The control system, with operator panel, is a complete and independent weighing unit.

Mixers are often installed in cramped spaces that make access difficult. Hinged gearboxes and motor assemblies hang on a horizontally hinged mount, allowing the two assemblies to swing out like double doors. The design provides easy access to bearings and shaft seals. The gearbox/motor assembly has a small gearmotor coupled to the main motor, disabling it during regular operation but allowing the mixing arms to turn slowly during washing or maintenance.

Technology makes a difference in the new HPGM countercurrent mixer. Its powerful concrete mixing s stars rotate around a center vertical a axis. An optimized mixing shovel a angle uses the latest flow dynamics engineering formulas and computer research. The shovel position and orientation delivers optimum mixing sheer intensity for the shortest mixing cycle time. Advanced Concrete Technologies. 603-431-5661. www.concretebiz.com.
Concrete to Go
When a project calls for concrete to be mixed onsite, portable mixers are the producer's best friend. A variety of styles are available to meet virtually any job requirement.
Barrel style multimixers
The false bottom drum design of Workman an mixers works with four-piece paddles to provide a very aggressive mixing action. They feature a one-piece removable drum that is driven by a gearbox, which eliminates external drive gears. The mixers can operate on 110V or 220V current. Mix concrete, mortar, stucco, or grout.

This easy-to-operate 4x4 mobile, self-loading concrete mixer acts as an independent, off-road mobile batching plant. It can produce and distribute concrete in the most difficult jobsites above- or below-ground. Features include drum slewing 300 degrees, front cab, hydraulically closed shovel, and electronic weighing system. Carmix. 705-897-1716. www.carmixcanada.ca.
Compact concrete mixer
The PortoMix concrete mixer has a steel frame, making it ideal for small footings and bases, binding block, and concrete patching. The unit's polyethylene drum mixes up to 4.5 cubic feet of material. PortoMix measures 34x23½x48½ inches, ideal for simple transportation. The 138-pound mixer can al also be used as a wheelbarrow to transport concrete, debris, and other materials.
