The crushing business
India’s growing construction activities, especially in roads, highways and urban infrastructure sector has been fuelling the demands for crushing and screening plants. With India’s rapid growth and need to urbanize, there has been lot of urban infrastructure projects that stated simultaneously in recent years. These gave rise to the demand in the market for crushing and screening plants both from major players and small.
The country is lucky have a number of big companies such as Sandvik, Powerscreen, Proman, Metso, Nawa besides others operating in India market to meet demand. With the growing number of public-private-partnership (PPP) projects under BOT and BOOT, there has been pressure on construction companies to finish projects on time, delivering good quality. This has necessitated demand for advanced and innovative products which can optimise the output. Key crushing and screening plants players are continuously working on developing a better product. While the basic machinery used in crushing and screening remained fundamentally unchanged for many years, the industry has nevertheless become considerably more hi-tech. Sandvik which has been making crushers for over 100 years, is involved into continuous research & development of crushers and crusher control systems to optimize their performance.
“The current offering in jaw crushers comprises of latest series of jaw crushers which includes models specially suited for mobile applications. Strength has been increased and weight has been reduced for high production and low total cost. We have incorporated best of the old and applied the benefits of the latest technology,” says Simon Meester, President, Sandvik Mining and Construction, India, who took charge of Indian operation earlier this year.
Sandvik cone crushers are of advanced design with a small footprint and high capacity in relation to size. They have high reduction efficiency and give very good product shape. With hydraulically adjusted CSS (closed side setting), the option of automation, a choice of several different crushing chambers, and many other high-performance features, each model is versatile, user-friendly and highly productive. The Sandvik CS- and CH-series of cone crushers have a wide field of use as they can easily be matched to changes in production through the proper selection of crushing chamber and eccentric throw, the company says.
“Our cone crushers are ideal for secondary and tertiary crushing and the compact and easy-to-service design makes them a perfect choice for mobile installations. Our crushers provide automatic overload protection and can be equipped with our automatic setting system ASRi. This system optimizes cone crusher efficiency and automatically adapts the crusher to variations in feed conditions. By continuously measuring and compensating for crusher liner wear, ASRi allows you fully utilize crusher liners and schedule liner replacements to coincide with planned maintenance stops. ASRi also assists in keeping your crusher choke fed. This maximizes rock-on-rock crushing, which helps to optimize the quality of the final product,” Meester adds.
Sandvik has established itself as one of key players in autogenous VSI (Vertical Shaft Impactor) crushing.
Another key player, Powerscreen is strongly committed to continuous innovation in design and technology for new equipment and improvements. “In recent years more customers have been adopting mobile technology versus static plants, but are looking for high capacity when they are in transition. Powerscreen has introduced numerous new products to meet these demands including some of the largest mobile crushing plants available such as the Powerscreen1500 Maxtrak cone crusher, Powerscreen XA750S jaw crusher and the flagship Warrior 2400 heavy duty screen,” says Rajen Khoda, Director of Sales-South Asia and Middle East, Powerscreen. He says that emphasis is placed upon designing machines that give the greatest level of fuel efficiency while at the same time providing the greatest level of output.
Powerscreen offers a comprehensive portfolio of tracked mobile jaw, cone, and impact crushers, as well as incline and horizontal screens and washing. “Operators of our equipment vary from small family owned quarry and mine operators to multi-national industry players, as well as contractors of all types. Our equipment is suitable for a multitude of applications across the Mining, Aggregates, Recycling and Sand & Gravel segments,” Khoda adds. His company will be exhibiting a number of tracked crushing and screening plants at booth 712 at Excon 2011 in Bangalore from November 23–27. The Powerscreen Metrotrak jaw crusher, Powerscreen 1000SR cone crusher and Powerscreen Chieftain 1400 mobile screen will all be on display.
Bangalore-based Proman who is working with a new technology for screening high moisture content and very fine material, would be showcasing its products during Excon 2011. “Other than that we are bringing in the latest designs of REMCO VSIs to the Indian markets. REMCO would be launching the 2011 series of VSIs globally while at Proman we would be doing this launch at Excon 2011 in India simultaneously,” says RS Raghavan, Managing Director, Proman.
He says that the crushing industry, as such is growing at a steady rate within the aggregate sectors; in mining like coal, limestone and other minerals there is a steady demand. The industrial mineral is an upcoming industry for crushing and screening.
Proman manufactures and supplies a wide range of crushing and screening equipment such as primary and secondary Jaw, Cone Crushers of 35 inch and 45 inch sizes, a wide range of Screens from 1.2 x 3.0 mtrs to 2.4 x 8.0 mtrs (1,2,3 and 4 deck), Vertical Shaft Impactor Crushers from 50 to 1500 Horse Power (HP) and sand washing plants from 20 TPH (tones per hour) to 200 TPH.
“Our Jaw Crushers namely LIPPMANN are oil lubricated with tapered roller bearings. Our Cone Crushers are very flexible in application with bush arrangement. And Vertical Shaft Impactors are built like crushers and very power-efficient with a very flexible option to maximize production. Our washing plant Ortner is very unique in its design and it consumes very little power and water. With these features Proman has always delivered products or crushing systems which work at the lowest operating cost to the end customer,” Raghavan adds.
Sandvik which offers both Mobile and Stationary crushers says it has invested heavily in research and development of new products and acquired many strong brands. “We can upgrade existing plants, deliver complete solutions and effect turnkey installations. We also supply individual crushers and screens, as well as key components and a wide range of consumables. A wide and versatile range for diversified applications and genuine Sandvik protection maximizes service life, cuts costs and reduces noise,” says Meester.
Powerscreen says its sees yet further potential for mobile equipment in the mining segment, where it already holds a commanding position, but also forecasts greater levels of penetration of its tracked mobile crushers, screens and wash plants into the aggregates sector.
