process of clinker grinding

    CLINKER GRINDING UNIT PROCESS Mechanical

    Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills. Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter grinding in mills.

CLINKER GRINDING IN CEMENT PRODUCTION

Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding. According to some hypotheses, only a thousandth blow of the ball is

OverviewComposition and preparationUsesClinker grinding aidsConversion to cement pasteContribution to global warmingCement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres to 25 millimetres in diameter. It is produced by sintering limestone and aluminosilicate materials such as clay during the cement kiln stage.

Breakthrough in Clinker Grinding

Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The European Cement Research Academy (ECRA) estimates that up to 70% of the power consumed in cement production is for material size reduction. Increasing the efficiency of particle size reduction could have a large impact on energy consumption in the

Clinker Grinding Station Process. The electric motor drives the disc through the reducer, and the hot air enters the vertical roller mill from the air inlet. The material falls from the feeding mouth to the center of the disc. Because of the centrifugal force, the material moves from the center of the disc to the edge of the disc. Grinding roller crushed, crushed material continues to move to

The grinding process differs depending on the pyro-processing process used. The feed to the kiln is called “raw meal.” Clinker is produced by pyro-processing the raw meal. The raw meal is burned at high temperatures, first by calcination of the materials and then by clinkerization to produce clinker. Various kiln types have been used historically or are used around the world. Besides the
