Key to the plants is the intuitive CS100 Control System, tried and tested in the world’s toughest environments. The system provides efficiency during production and delivers built-in statistical reports to uncover cost-saving opportunities. Many of the plants’ features are also built around providing efficiency and ultimately reducing costs and improving profits.

A compact, modular four- or five-bin feeder ensures quick transport and assembly. The plants’ small footprint allows ValueTec to fit into tight spaces. The quality of mix is consistent from the feed stage due to a large storage capacity. Frequency controlled conveyers extending to the drum inlet chute ensure hassle-free material delivery. A simple, effective calibration system provides essential support. “Value is added throughout the production process,” says Sapru. “For example, the low tipping heights for feeder bins eliminate the need for construction of expensive ramps. Instead, a loader can be used with a small ramp.”

The fully modulating burner features a simple, easy-to-adjust mechanism to set the air/fuel ratio for precise combustion and emissions control. The burner combines with the baghouse to ensure suspended particulate matter (SPM) levels are within limits and the carbon footprint is minimal. Direct-coupled gear motors also add value by reducing fuel and maintenance costs. The counterflow dryer drum is compact, efficient and reliable. Quality is boosted through a screen that uses vibratory motors, providing uniform distribution of aggregate on the screen mesh surface. Circular material movement and transverse transport between the two shafts ensure thorough mixing. The plants feature safety measures to protect plant personnel.

Ammann & Apollo range of equipment will cater to expressways, national highways, state, city and village roads. The products will be manufactured to global standards with technology from Europe, and with components made in India, they will be competitively priced.

The controls in its 200 TPH plants are fully automated, and semi-automated in its new 120 TPH plants, which makes them very user-friendly.

Informs Raj Shrivastava, Executive In-charge, Crushing & Screening & HMAP-TIL Limited, “TIL, under strategic alliance with Astec Inc. USA, offers a range of world-class Hot mix asphalt plants in India. Apart from being energy efficient, our plants can utilize up to 50% Recycled Asphalt Pavement (RAP). Faster setup by virtue of their modular design, ensures higher uptime and availability of the plants. Our continuous-type asphalt plants can be towed away and installed at ease. In fact, they can be dismantled and reassembled in 24 to 72 hours depending on the technology and size, as compared to the 6 to 12 weeks taken for a batch plant.”

Kaushik Cesan is ramping up manufacturing capacity for producing higher capacit plants of up to 300 TPH. The modular design of the plants (built on European standards and engineering specification) makes them easier to install and dismantle within two to three days, and easy to transport. Critical components are sourced from reputed manufacturers, especially the gears, which are of Turkish origin. PLC system is from Phoenix, Motors are Siemens or Crompton. The fabricated grilled material is made at Kaushik’s factory as per Cesan’s standard for durability and safety.

Saumil Shah
Says Saumil Shah, Director, Kaushik Engineering Works, “Our plants are known for the best fuel efficiency in the industry as the burner and the bag house are synchronized so the fuel-efficiency is at least 4.5 liter/ton as compared to 5.5 liters/ton in other plants. This also minimizes energy wastage and makes them very cost-effective, besides which the SCADA system in the plants gives online support to plants working in the most remote locations, which helps solve problems and minimize downtime.”

Adds Shah, “We have multiple options to use RAP, with more than three machines in India using RAP currently. Our plants can take 15-20% of RAP materials, but we are not making fully RAP-enabled plants due to the high cost. However, we plan to make a greater number of plants to take on RAP materials.”

Says Paresh Patel, MD, Alltech Industries India Pvt Ltd, “Targeting upcoming road and expressway projects, we launched small (80tph) to high (240tph) asphalt batch mix plants. We proved maximum fuel efficient, less maintenance, cost effective and high production plants for both the domestic as well as international markets.”

According to him, the highest possible addition of RAP depends mainly on its grading curve, which should (as far as possible) be approximated to the desired grading curve of the finished product. “This cannot be achieved with normal crushing plants which produce too many fines and sand for proper granulation, but at Alltech, we have the technology for utilization of RAP materials to the highest extent.”

He adds, “Fuel quality and availability is a big challenge in India, hence, we have designed multi fuel systems in our plants such that customers can use waste, heavy or recycled oil, diesel, Ldo or gas, supported by our various burners. We also ensure faster and cheaper transportation and quick set up of our plants because all parts have standardized transport dimensions that allow use of standard trucks or 20 and 40-ft trailers.”

At Atlas Technologies Pvt. Ltd., improvisations are being made to make the plants better adapted to higher aggregate moisture content. The bag filters have three rotors on top for efficient cleaning. The mixing unit comes with planetary gear boxes on each shaft, which is better for torque absorption. Superior quality materials for liners, arms and tips ensure longer lifespan of the plant. The thermal oil heaters with three pass systems, specially designed by the vendor for Atlas, enables heat transfer efficiency with use of minimum fuel.

“We have supplied plant burners in the past that work on PNG gas both for drying drum as well as thermic heater, which give true value to customers. We have supplied 5 asphalt batch mix plants with RAP system. We have designs that can add up to 30% RAP material, and we are one of the front runners in providing solutions for addition of reclaimed asphalt,” informs Bhavesh Patel, MD, Atlas Technologies Pvt. Ltd.

He informs that their stationary plants’ modular structure enables faster installation: each unit can be picked and placed in a truck for transport, while the major units have skid plates for quick installation. The company has also introduced Mobile Asphalt Batch Mix plant that can be installed and commissioned in less than 48 hours using a single hydra crane. All the units are fully mobile, and each chassis can be attached to the kingpin of a trailer. The machine is the best option for customers, who shift sites frequently.
