Moving towards higher capacity machines, the company has added a new range of jaw crushers with the same drive motor. Further, to meet demand for bigger secondary crushers of +400 tph, it has added a new cone crusher. The bigger machines will reduce the number of machines and accessories, which in turn, will reduce the cost/ton of production, and enhance efficiency.
“To improve the life of the wear parts, such as for abrasive ores like quartzite, we’ve extensively studied the wear pattern and profiles of jaw Plates and cone liners of such plants and developed specific designs to suit the applications,” informs Mr. Pai.
Puzzolana customers are serviced by the company’s engineers who visit the sites and recommend the parts that the quarry owners should stock. Spare parts are also available with its dealers. “We have a wide network of dealers in India as well as in Africa, Middle East, South East Asia and Bhutan. We also offer annual maintenance contracts, besides periodic checks of plants and advise on operation, maintenance and refurbishment of equipment periodically, as part of product support packages,” says Mr. Pai.
He explains, “The Kleeman screens features high levels of flexibility. The screen media of the MS 952 and MS 953 EVO can be changed quickly for different operating requirements. The screen media are easily accessible from all sides and are secured with wedges. Other service components, such as the large engine compartment, are also easy to service. There are useful additional options for the plant. An optional belt cover and a water system at the fine grain discharge conveyor are offered to reduce the amount of dust when working in densely populated areas.”
Mr. Palagiri adds, “The screening plant is controlled via a user-friendly, mobile control panel. It can be connected at three different locations on the plant. The safety of the plant operator is increased with the improved visibility of the folding and lowering functions. The control panel has an intuitive design with a clear, coloured display of all controllable machine functions.” Kleemann crushing plants, according to the company has carried some recent innovations. This includes, CFS – Continuous crusher feed system, diesel – electric drive; crusher de-blocking system.
According to Mr. Ashoktaru Chattopadhyay, Head of Crushing and Screening business - Sandvik India, “We are delivering solutions, that goes on towards understanding customer requirement and provide the best solution by using each crusher in circuit for optimum use.
He says, “Our CH540, 180 tph cone crushers delivers between 0-20 mm of manufactured sand, CH 440, 300 tph cone crushers produces between 0-40 mm aggregates while our CH 550, 400 tph crushers provides throughput between 0-40 mm of crushed aggregates.”
Taking cognizance of higher throughput needs, Proman is offering its new heavy-duty Projaw 5040 jaw crushers and Procone 5010 cone crushers. According to Mr. R.S. Raghavan, MD, Proman, “Pro Jaw 5040 jaw crusher is designed based on our vast experience in the Indian rocks and crushing industry requirements.
He informs, “Proman jaw and cone crushers are designed for optimum crushing ratio, along with design flexibility, and options such as automatic lubrication, easy closed side setting, and standard automatic tramp relief. Further, our cone crushers’ liners do not need backing compound, our vertical shaft impactors are serviceable from the top, and have drop in tips, so the units are easy to service. For ease of transportation, assembly and dismantling, they are designed such that they can be mounted on skids, fixed, or wheeled.” Proman provides operator training at sites and at its facility, and has deputed service engineers across the country.
Propel Industries is set to introduce its new tracked, three stages, 200 and 250 tph jaw and cone plants, along with three and four deck screens. The new plants, manufactured at the company’s new facility at Coimbatore, will be targeted at road contractors and producers of commercial aggregates.
The tracked plants will be offered to customers with an option of Caterpillar and Scania engines. Propel will also be introducing higher capacity skid and mobile configured crushers. “Targeting limestone production for cement industries, we are working on higher capacity, close side settings adjusted, 600 tph jaw crushers. The unit, with an opening of 1400x1200 mm, will be able to accommodate 1-meter boulders easily,” adds Mr. Kumar.
Propel manufactures jaw and cone crushers between 150-200 and 250-300tph. Its vertical shaft impactor line comprises 75,100,150,200 and 250 tph.It has made improvisations in its cone crushers to optimize operations of the plant owners. The improved cone crushers can now be altered to produce manufactured sand. The crushing chamber can be altered by changing the concave and mantle. This will reduce the gap between the concave and improve production of fine aggregates and sand. Propel’s sand washing and classifier equipments, Prowash 100-150 and 200 can produce plaster and manufactured sand from the cone crusher simultaneously during the operation process.
Marsman is looking to broaden its presence in mobile plants. Says Mr. Varma, “The latest trend in the market is mobile crushing and screening. Our impactor, jaw and screens have been finding favourable response in India and abroad. Demand for mobile crushing has gone up as it enables transporting the plant altogether from one site to another once the project is complete. A major advantage is that the plants can be erected, commissioned and dismantled in the shortest possible time.”
Marsman has also been strengthening its after-sales support to its customers. Mr. Varma, says, “The crushing and screening market is highly service-oriented. We have in place a dedicated team of highly skilled engineers located in different parts of the country, and they are just a call away. Once the machine is dispatched to a customer’s site our service engineer is deployed for erection and commissioning, besides which, is available throughout the warranty/post warranty period.”
The company has a special team of engineers for turnkey crushing and screening plants to assist in the erection, commissioning, smooth running, and to ensure that the output capacity is being met. Genuine spare parts of the company are stocked in various regions to meet urgent demand from users and curtail lead times. The company also offers contract crushing and annual maintenance contracts to customers.
Improvisations have also been made in the blow bar setting mechanism of the horizontal shaft impactors. Says Mr. Prajapati, “The blow bar setting mechanism is more user-friendly now, and it is also easier to replace the parts and components in our HSI. Design improvements made in the rotor and apron will now prevent components from falling in the crusher chamber (due to vibration) and damaging the machine.”
The company renders technical support through its erection and commission engineers stationed at quarry sites for two months to ensure smooth running of the machines.
Higher Plant Efficiency & Productivity
Volvo Penta will also be promoting its diesel generating sets for stationery crushing and screening plants. “Volvo Penta powered continuous duty diesel generating sets in range of 250kVA to 650kVA have a proven track record in reliability,fuel efficiency and uptime. We will be looking for more business opportunities through our channel partners Supernova, Sterling & Wilson, Power Engineering, Rai and Kohler,” informs Mr. Nilsson.
Promoting sales through newer product development and advancement in the existing product lines is a notable initiative of the crusher manufacturers. However, retention of business will depend on appropriate, most vital continuous product support as customers may require some time to fully get themselves acclimatized to the newer technology offerings. There will also be requirement of support for erection and operation of plants based on the changing requirement of the quarry owners and operators.
