Manufacture of clinker and cement in the factories complex

• The Factories Complex of the National Company for Cement in Beni Suef, produces all types of clinker and cement of different grades. The cement production process begins within the factories complex with the stage of extracting raw materials from the quarries and transporting them using heavy equipment and dump trucks to the crusher sites, and the crushers transfer the raw materials from large blocks to crushed blocks of suitable sizes, the factory includes (6) limestone crusher at a production rate of (1200) tons / hour per crusher and (6) Clay crusher at a production rate of (400) tons / hour per crusher and (3) gypsum crusher at a rate of (350) Ton / hour per crusher and all these crushers and plant equipment are European in origin.
• After the crushing stage, the raw materials are transported to the factories complex. This is done through a network of belts. The total lengths of the internal and external belts are 22 km, with a width of (1) m, to (6) storage for limestone and clay to store (510) thousand tons and (3) storage for additives to store (30) thousand tons of sand, (30) thousand tons of iron oxide ore and (36) thousand tons of gypsum.
• This is followed by the stage of assigning the weights of mixing the raw materials according to the specified proportions according to the type of clinker that will be produced, then they are transferred to the vertical mills for grinding after mixing to obtain a homogeneous mixture of those materials at a grinding rate of (500) tons / hour for one mill. Then the dust is separated from the raw materials from through a group of filters and silos to collect dust
• After the grinding process, the homogeneous mixture is stored in (6) concrete silos with a storage capacity of (25) thousand tons per silo, the height of one silo is (71) m and diameter (25) m to ensure the continuity of feeding the primary kilns with raw materials, then the homogeneous mixture is transferred to (6) A primary furnace, each with a height of (126) m, to preheat the raw materials up to (800) degrees Celsius.
