Hydraulic roller presses boost productivity at Orient Cement

June 22, 2018 Avanish Karrahe

Orient Cement shares how the installation of two hydraulic roller press systems supported the efficiency and sustainability objectives of their Karnataka plant.

The limestone-rich belt of Karnataka in India is home to many cement plants, and the market for roller presses in the region is highly competitive. Given the numerous different options on the market, choosing the correct roller press solution and the equipment supplier can be daunting for plant owners. For Orient Cement, selecting the FLSmidth Hydraulic Roller Press (HRP) has proven to be a cost-effective solution.

Finding the right solution
With a desire to optimise productivity, Orient Cement established selection criteria for evaluating a new roller press system for use in its 6,600 tonnes-per-day integrated greenfield plant. The three most critical objectives were high production performance, low power consumption, and grinding without adding water.

“Hydraulic roller press systems are the best choice for the raw materials in our region as the materials are quite dry in nature and have high grindability. We also require a waterless operation, so the HRP system was the obvious solution for us.” - Shyam Asawa, Head of Projects at Orient Cement

Low power, no water
Shortly after the installation, it was evident that Orient Cement’s project objectives would be achieved, with all performance guarantees successfully delivered. As shown in table 1, actual production exceeded the intended capacity target by 6.5 percent – at a lower power consumption and with zero water consumption.

Today, the grinding system at the Karnataka plant is performing well. After the initial 10,000 hours, the conventional wear surface remains in good condition. No repair work has been required or performed thus far. This strong result is a testament to both the quality and durability of the equipment.

The HRP is suitable for upgrades and new installations. In some cases, an upgrade can more than double the capacity while reducing energy consumption by 30%.

“We chose FLSmidth to supply the HRP system for raw grinding based on its brand credibility and industry experience. FLSmidth has yet again proven itself and has clearly set a new standard with its superior performance and commendable results,” says Mr. Asawa.
