New orders for Gebr Pfeiffer
In September 2003, Gebr Pfeiffer AG received an order from Taiwan for the supply of an MPS 3070 BK type coal mill. Winfresh International Limited, a subsidiary of the Taiwanese cement producer Lucky Cement, ordered a Pfeiffer vertical roller mill for anthracite coal grinding. The mill is intended for their new green field cement production facility located in Phuc Son, Vietnam. The MPS vertical roller mill is rated for a capacity of 33tph, and its delivery is scheduled for July 2004.
Gebr Pfeiffer AG has received an order for two grinding plants from Associated Cement Companies Mumbai, India. The plants for the grinding of cement raw material and coal are to be set up in their Chaibasa cement factory near Jamshedpur. They will furnish the feed material for a new 5000-tpd rotary kiln with preheater. The former production line with wet kiln will thus be replaced. To boost the exploitation of the quarry, the ordinary limestone will be enhanced by the addition of high calcium carbonate limestone slurry. The slurry, which contains approximately 35% of water and already has product fineness, will be injected straight into the raw mill. Exhaust gases from the preheater and the clinker cooler will serve to cover the heat requirement.
For the raw material grinding task, Gebr. Pfeiffer AG sold an MPS 4250 B with a 1900-kW drive power. The mill will reach a guaranteed production rate of 340tph with a fineness of 14% R 90 µm, approximately 41tph of which will stem from the limestone slurry.
The coal mill, an MPS 2800 BK model with a 900-kW drive power, will attain a guaranteed production rate of 35tph with a fineness of 14% R 90 µm.
Gebr Pfeiffer AG has received a contract for the supply of a lime hydrating plant to Cementos Progreso¹s Guatemala-based San Miguel lime works. The order comprises a KLV lime hydrator for hydrating quicklime from an existing shaft kiln and a new kiln which is yet to be built. A downstream 2-stage separating and grinding plant, equipped with two SLV high-efficiency separators and an MRD-type double hard ball mill, is to produce two end products, one intended for the sugar industry, the other for the building industry. An overall production rate of 30tph will be met, which will allow Cementos Progreso to shut down their old hydrating plant built together with the first shaft kiln.
Gebr. Pfeiffer AG will supply the entire machinery, including the electric equipment, the instrumentation and the process control equipment for the hydrating plant. The machinery is to go into operation in the first half of 2005.
