Basic Process of Cement Manufacturing and Producing


Sand and gravel used in construction can be described as a long history,which now has become indispensable,especially the aggregate, can be said to have made tremendous contributions to the state’s economic construction in obscurity. It can be said that the staple diet of modern construction is sand and grave.If there is no modern reinforced concrete buildings erected,no emergence of excellent variety of road pavement, subgrade and new building materials.It is fully reflected in our sand and gravel production processing equipment,crusher,sand making machine and other mining machinery has witnessed rapid development in order to fully meet the demand of the aggregate production of mineral processing equipment, and further consolidate the cement and concrete markets.
Cement manufacturing as a procedure and as a big production line has undergone many phases of makeover in current times.
An integrated cement manufacturing process is that prepares the raw mix, feeds it to the pyro-processing system (kiln), and then grinds the clinker from the kiln system into various cement products. Finished cement is stored in large silos on site or bagged for small quantity use.
Crushing process: The raw materials mainly limestone, clay, coke are crushed in the separate crushers and stored automatically into the respective silos.
Storage and Proportioning: The different raw materials are extracted from the silos in the desired proportion through table feeders and conveyed to raw mill.
Raw Milling: The raw mix is ground into a ballgrinder at desired fineness to produce Raw Meal, and transported for Homogenizing.
Blending & Homogenization: The raw meal is homogenized in the blending silos, and is stored automatically into a storage silo for feeding to the kiln. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like flotation cell, Henan Hongxing is always doing the best in products and service.secondary cone crusher:http://www.china-hxjq.com/p14.html
Palletizing & Burning: The nodules are made into a nodulisor and charged into the kiln for burning. The clinker after discharge is stored in the clinker yard through deep Bucket Elevator.
Clinker/gypsum crushing, storage & proportioning:
Clinker & Gypsum after crushing stored into the hoppers and extracted in the desired proportion with the help of table feeders and transported to the mill Hopper.
Cement Grinding: The clinker & Gypsum mix is ground to produce cement.
Storage & Packing: The cement is stored into the cement silos and aerated, tested and packed for dispatch.
Cement manufacturing plants:
Cement manufacturing plants should be include high efficient separator which has such characteristics as low energy consumption, cooling and drying, high availability, relatively low capital expenditure, high selectivity, and, proper product separation.
With the development and innovation of society, science and technology,Hxjq cone crusher has reached the international level. Recent years, new type hydraulic cone crusher with its high crushing frequency and efficiency of the crushing chamber shaped perfectly, higher capacity than other models of crusher, which greatly improved laminated crushing effect between the particles of the material, to make sure broken products to keep the uniform cube.The use of hydraulic insurance, hydraulic adjustment and hydraulic chamber clea,let the operation more convenient and easy to automate, easier maintenance.This crusher as been widely applied to the hematite mineral processing, gold processing, manganese ore, equipment, copper and mineral processing field.
