Boosting productivity through crushers and screening equipment

The most obvious way to increase the productivity of crushing is to ensure a steady supply of raw material,use the right equipment combination and employ high-performing, well-designed and built, strong, fine-tuned machines.

High productivity is associated with high output and minimal waste, according to Manesh Thomas, Managing Director, Modern Road Products. “Using the right combo is especially vital when you need to crush very hard materials, a very tough job for any machine.”

Certain features of a crusher are amenable to boost operational productivity and reduce operation cost per tonne. Among these, Kiran Jain, Director, Shri Dakshayani M Sand, and Vice President, Karnataka Quarry and Crusher Owners Association, counts the motor size and the number of ports in the rotor design.

In addition, Bobby, Managing Director, Amity Rock Products, recommends “a well-enclosed hydraulic circuit with precision controls to ensure you use just the optimum power and machine capability, and reduce downtime and wear consumption.”

Dr S R Samal, Chairman and MD, Kalinga Commercial Corporation, which uses two sets of Kleemann crushers –jaw + cone + screen (MC110Z + MCO9 + MS 703) – in its iron ore mines in Odisha, suggests looking for a plant with lower fuel consumption, something the Kleeman plant achieves, or with unique features like a continuous feed system that increases production and reduces wear cost.

Plants that are used to produce both sand as well as aggregate must deliver the desired quantities of each to meet the desired productivity level. “At Mathrani Infra, a Puzzolana 200 TPH three-stage crusher is producing 45-50 per cent high-quality manufactured sand and aggregates, delivering over 1,600 tonne output in a single shift,” says Jitendra Mathrani, Director, Mathrani Mining Infrastructure. “The low power consumption makes the plant an economical, value-for-money machine.”

“Productivity implies that the machines are working fine without any shake and without even 1-mm variance,” explains Ravindra Rao, Director, Sai Srinivasa Laxmi Stone Crushers. “Our production is comparable with the industry average. The low cost of Puzzolana spares helps ensure our productivity and profitability. We have crushed upwards of 1.9 million tonne without any major replacements.”
