Raw Materials The raw material used in modern asphalt manufacturing is petroleum which is a naturally The Manufacturing Process This not only eliminates the pollution but also increases the heating efficiency of the process Higher costs of asphalt cement stone and sand have forced the industry to increase efficiencies and recycle

Steps of Cement Production Process Cement is one of the most common and important building materials It is a very critical ingredient because only cement has the ability to increase the viscosity of concrete which in turn provides the ability to lock sand and gravel together in concrete mixtures

Cement Cement Extraction and processing Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones slates and some shales with the aid of blasting when necessary Some deposits are mined by underground methods

Raw Materials processing included Setting and curing and cement manufacturing process Process Discretion Wet process Semidry process Dry process and Finish process

The raw materials which supply cement works and which may be required in quantities of over 4000 tonnes per day must be thoroughly proven if the plant is to run successfully Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns

Lime Component Limestone Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and one is of predominently fine grained cryistalline structure its hardness is between 18 to 30 of the Mohs scale of hardness and specific gravity 2 To 28 Limestone usually contains admixtures of clay substance or iron compounds which influnces its colour

Cement Production Raw Meal Production in Steps Perfectly mixed accurately fed without pulsation and precisely weighed The key word is quality And this quality is achieved during cement production with exactly matched process steps In the first stage the raw meal is produced as described below

Fine ground raw meal is then stored and further homogenized in the raw meal silo The heart of the cement manufacturing process is the thermal process in the kiln system with clinker capacities of up to 12000 tonnes per day nowadays A kiln system consists of a static preheating system with typically five cyclone stages and a precalciner
