Sustainability on any scale.
ALmix Recycled Material Handling | Overview
Recycled Asphalt Pavement or RAP continues to be a driving component of today’s asphalt plant designs. As with our cold feed systems, we start with a massive design built to take the day in, day out abuse associated with normal plant production. The RAP feeder incorporates our direct connected healical gearbox and flux vector technology. Rugged bar grizzlies and air cannons to prevent material bridging are standard equipment. RAP screens and crushers are available to process even the most difficult RAP pile.
ALmix Recycled Material Handling | Configurations
ALmix offers two RAP bin system configurations to fit any contractor’s needs:
Skid-Mounted RAP System
Portable RAP System
ALmix Recycled Material Handling | Features
ALmix RAP bins feature many of the same rugged features seen in our cold feed bins. Each recycle bin is fitted with a grizzly with 6" openings to reject oversized materials. The grizzlys are constructed from 1/2" x 6" flat bar and is notched for cross supports to provide a smooth surface for the loader bucket. Each bin is fitted with a multiple amplitude electric vibrator and an air cannon to facilitate flow of wet, sticky RAP materials.
ALmix Recycled Material Handling | Belt Feeders
Like our cold feed bins, each RAP bin is equipped with our belt feeder system, powered by a helical gear motor through a fully-digital AC flux vector drive. Massive ACME threads support the feeder frames and allow the belt clearance to the bin to be fine-tuned to the aggregate size. Our unique troughing roll design eliminates leaking without the need for troublesome skirt boards. Each ALmix belt feeders also feature material flow detectors which activates a sequenced shut down if aggregate ceases to flow for more than a preset amount of time.
ALmix Recycled Material Handling | RAP Conveyors and Screens
RAP COLLECTING CONVEYOR: The ALmix RAP collecting coneyors feature a 30-inch wide channel frame RAP collecting conveyor driven by a helical gear brake motor mounted at the gravity take-up for ease of servicing and elimination of the off-loading associated with head shaft mounted gear boxes. The conveyor features a lagged, magnetized head pulley, self-cleaning tail pulley, 2-ply rated skived belting, permanently sealed troughing idlers, belt take-up assembly and open mesh belt guard. The magnetized head pulley is equipped with a chute to discharge collected metallic debris away from the unit. The RAP collecting conveyor feeds collected materials to the RAP screen.
RAP SCALPING SCREEN: For RAP processing, a single deck scalping screen can be provided as a modular unit mounted over the RAP weigh conveyor on a heavy H-beam frame that includes base plates and side support steel. The scalping screen is driven by a motor mounted on a heavy duty pivoted motor base. A walkway/platform with handrails is provided on two sides of the screen to facilitate changing screen cloths.
RAP WEIGH CONVEYOR: The ALmix RAP weigh conveyor is a 30-inch wide I-beam frame incline conveyor that delivers material from the RAP screen discharge hopper to the RAP entry chute on the drum mixer. The conveyor features a lagged head pulley, self-cleaning tail pulley, 2-ply rated skived belting, permanently sealed troughing idlers, belt take-up assembly, belt scraper and open mesh belt guard. The conveyor is driven through a helical gear brake motor mounted at the gravity take-up for ease of servicing. This conveyor contains the Scitronics recycle weighbridge with speed sensor and test weight. Wind guards are provided to insure accurate weighing. The load cell is insulated top and bottom with ceramic isolators and includes a heavy ground strap around the load cell for lightening protection. An air operated by-pass chute is provided to allow belt scale calibration and feeder bin clean-out.
