Mechanised cleaning at Ambuja Cement
Scope for cleaning in Cement Industry
The cement manufacturing plant generates a lot of solid dust besides spillage of raw material on the shop floor. Cleaning of solid dust, raw materials which overflow and fine dust on road surface during manufacturing process of cement forms the main part of housekeeping.
All floors and roads require daily cleaning / sweeping. When there is heavy wind malfunctioning of any equipment, the cleaning of surrounding area is a challenging job.
In a plant, the areas to be clean are limestone crushing section, raw mill, kiln section, coal mill, cement mill, packing plant, CCR building, bulk loading area, personnel department area and inside road. Outside the plant, the areas include, the street from the main highway to the plant, and the colony. About 60,000 sq. mt and 36,000 sq. mt of the plants area and 23,000 sq. mt of the port terminal is covered by road sweeping machines.
Tennant machines at Ambuja Cement
We have four of the Tennant 800D machines in three of the cement manufacturing units, Hako machine for the Muldwarka port terminal and TPS VAC 750 D road sweeping machine for the outside main road and mines.
Housekeeping is managed by the civil department. There are 15 contract workers for operating Tennat and TPS machines in two shifts.
The general air pollution is controlled by providing baghouse, ESP and bagfilter.
Of the several initiatives taken by Ambuja Cement to adopt eco-friendly practices, one of them is using biomass at its captive power plant. The plant is presently using 24 types of biomass collected from villages of Ropar, Ludhiana, Hoshiarpur, Phagwara, Fatehgarh Sahib, Patiala and other districts. It includes biomass, rice husk, cow dung cakes, sunflower stems, maize cobs, sugar mills waste, etc.
Use of biomass has brought respite for villagers around, who find it difficult to manage agriculture waste and stock it.
Ambuja started using biomass for its captive plant in 2004. During four months of 2005, the plant drew 100% power from the biomass and utilised around 75,000 tonnes of biomass. The company aims at replicating this model at its other plants in the country as well.
