Cement is a crucial building material used in construction. The Cement manufacturing process involves the extraction and preparation of raw materials, such as Limestone, clay, shale, iron ore, and Gypsum. These materials are crushed, ground, and blended to form a raw meal, which is then heated in a kiln at high temperatures.
Cement is packed by high efficiency rotary packers which are electronically controlled. Packers are highly precise with tolerance of +/- 0.5%. The main feature of electronic packers are that. It shows the display of weight of each bag. It ensures the bags to fall from nozzles only after filling of cement to accurate weight of 50.2 kg.
