September 27, 2017 - Rock to Road checks out some of the latest asphalt-related technologies.

Asphalt Drum Mixers’s ADM EX120 Asphalt Plant has the longest aggregate drying and mixing times in the industry. The 120-tph plant is capable of processing as much as 50 per cent RAP. Counterflow technology with separate drying and mixing zones allows the EX120 to achieve maximum heat transfer and fuel efficiency. The entire EX120 plant sits on one chassis for easy movement from site to site. In addition, one plant operator and one loader operator can control the EX120.

Gencor’s Ultraplant concept is the most fuel efficient, environmentally clean and lowest maintenance design available to the hot mix industry. A totally integrated drum concept that allows high production continuous mix with high-volume, high moisture recycle, all in a unitized drum design. The Gencor Ultraplant combines simple design with the most advanced control technology and massive heavy construction unmatched in the industry. Backed by world class product support and training, Gencor Ultraplants provide contractors years of dependable long life.

Enhanced aggregates and reclaimed asphalt pavement (RAP) processing technology built into Kleemann products like the Tier 4 final-compliant Mobirex MR 110 ZSi EVO2 and the MR 130 ZSi EVO2 impact crushers are boosting productivity and product quality for operators. With these mobile impactors, the “S” indicates a Mobirex unit with an optional secondary vibrating screen with extra-large screening surface mounted on the discharge conveyor. This secondary screen unit can produce spec material, potentially eliminating the need for a separate screen. The feeding unit has hydraulically folding hopper walls and locking system, which speeds setup. A vibrating double-deck prescreen between hopper and crusher eliminates fines from the product flow before they enter the crusher. These crushers feature a new inlet geometry, which allows better penetration of the material into the range of the rotor. The rotor ledges are held securely by a new user-friendly clamping system.

Terex MPS
Terex Minerals Processing Systems’ Cedarapids CRH1313R Portable HSI/Screen Plant is a complete closed-circuit standalone plant designed for quick setup with simple tools. The Cedarapids IP1313 impactor is built for high production (50” rotor, 3 or 4 bar); and features a patent-pending dual slope 2-deck screen (17-degree top deck, 15-degree bottom deck) that handles heavy loads. It has the capability to return both screen deck products to the crusher to maximize the plant’s capacity. The heavy-duty under crusher pan feeder provides large discharge clearance and absorbs high velocity crusher discharge, preventing conveyor belt damage. Additional features include a 48” x 16’ high-stroke Cedarapids Advantage feeder with 60” grizzly bar or optional steeped tine style grizzly section; a Tier 4, 450-hp diesel engine with hydraulic clutch split drive to crusher and generator; a 200-hp generator and more.

ELRUS Control Towers provide a secure climate controlled operator environment with a 360-degree view of the crushing spread or asphalt plant. All towers come fully outfitted with lights, receptacles, shelving, bronze tint laminated safety glass, acoustical foam interior with 1-1/2” insulation, heavy-duty rubber flooring and stainless steel kickboards, roll down see-through blinds, fully adjustable captain’s chair, remote controlled hydraulic raise and lower assembly c/w 12-volt power pack, tank, lift cylinder, scissor lift and stairway.

The GT205 Hybrid Multi-Frequency Screen features a high performance 5x20 screen designed for aggregate, recycling, construction and industrial markets and has the ability to run on either line power or diesel power when necessary. With its multi-frequency technology, end users can expect up to 50 per cent higher screening capacity on the bottom deck. The GT205 provides users with on-site flexibility and its simple controls create an easy-to-operate machine, resulting in increased uptime.
