A Prosperous Partnership
In December 2006, Vasavadatta Cement's new 3800 tpd production line in Vasavadatta district, Gulbarga, Karnataka, came into operation. High-pressure grinding rolls (HPGR) POLYCOM® for raw material grinding and cement grinding, and static/dynamic separators SEPOL® HR are used. Whereas the raw grinding HPGR is operated in finish grinding mode, for cement grinding the HPGR-Separator circuit is combined with a subsequent closed-circuit ball mill system. D. S. Bindra, Vasavadatta Cement, India, and A. Halbleib and R. Schnatz, Polysius AG, Germany, report on the successful new developments at the Vasavadatta plant*. *Based on a paper presented at the NCB International Cement Seminar, New Delhi, 27 - 30 November 2007.

If Aerospace Companies Designed Dryers...
Thanks to recent improvements in computing ability and technological contributions made by Douglas Aircraft, Boeing, Lockheed, and NASA, Grenzebach has been able to confidently provide solutions to the challenges that have plagued dryer manufacturers since the world's first dryer was put into operation. Computational Fluid Dynamics (CFD) is an analytical method that allows airflow trends to be calculated and observed. Ryan Holbird, Grenzebach Maschinenbau GmbH, Germany, describes the company's newest tool for addressing dryer performance improvement opportunities.
Exceeding Expectations
José Miguel Garcia, Chief of Production, El Alto plant, describes the modifications to the company's white cement line. Before the improvements, the white kiln's production capacity was 720 tpd of clinker, while atmospheric pollutant emissions were around 1630 mg/Nm3 NOx and 990 mg/Nm3 of SO2. Following the modifications, clinker production stands at 980 tpd, NOx emissions are <1000 mg/Nm3 and SOx emissions are <120 mg/Nm3.
Saving Money in the Baghouse
Each filter is unique and the prediction of the behaviour of different filter media demands a thorough review of all process details. Most of the costs are indirectly proportional to the bag life and the fan power, which usually represents the biggest expense factor related to baghouses. Pressure drop, and thus fan power consumption, are strongly influenced by the filter bag construction. Therefore, an economical comparison of different filter media needs to include more than just the price of the bags, divided by years of expected bag life. Georg Rathwallner, Evonik Fibres, Austria, quantifies the possible reductions of operating and maintenance costs available by choosing the correct filter media and adopting the right control parameters for the baghouse.
