In the calcination stage the cement kiln used by the wet process is longer in comparison to the dry process and there is no preheater and precalciner in front of the kiln The temperature in cement kiln can reach ℃ slurry in it is heated and dried and finally forming the clinker compounds namely Dicalcium Silicate Tricalcium
Rotary cement kilns as used in the cement industry take the form of a long cylinder supported on rollers They vary greatly in diameter and length from 15 × 18 m to 4 × 140 m In the larger kilns the ratio of length to diameter generally varies between 30 and 401
1 when the strength of cement is kept unchanged The yield of cement mill can be increased by 25 the minimum yield can be guaranteed by 20 and the power saving can be saved by 1725 2 increasing the grade of cement to ensure the stability of cement quality
Cement grinding is a vital link in the cement production line and the most energyintensive process The main function of ceent grinding plant is to grind cement clinker and gelling agent performance adjusting material etc into a suitable particle size expressed by fineness specific surface area etc form a certain particle gradation and increase its hydration area
The oxygen enrichment technology is established in some cement plants in order to improve production capacity An increase of 25 to 50 short term experiments kiln capacity by oxygen enrichment to 3035 vol in the combustion air has been reported Oxygen enrichment has not been applied to reduce CO 2 emissions so far But the use of enriched combustion air may result
Cement Plant Work Site Equipment Involved in Cement Equipment Cement Machinery The main cement machinery includes cement rotary kiln cyclone preheater and grate type cooler The cement rotary is the main cement machinery for burning cement clinker which has been widely used in the cement metallurgy chemical industry etc
Mini cement plant is also called small cement plant which is composed of a furnace shell a support unit a support unit thrust a driving unit a movable kiln head kiln tail sealing device a combustion device etc Mini cement plant also has other nam
After crushing reduces and make it maximum size of about 5 to 6 inches
The cement rotary kiln is a cylindrical body with a certain inclination and the inclination is 3 to 35 The rotation of the kiln is used to promote the stirring of the material in the rotary kiln and the materials are mixed and contacted for react
The original rotary cement kilns were called wet process kilns In their basic form they were relatively simple compared with modern developments The raw meal was supplied at ambient temperature in the form of a slurry A wet process kiln may be up to 200m long and 6m in diameter
Wellestablished technology on the one hand allows the rotary kiln of any cement plant to be fired with lowvolatile fuels such as petcoke lowvolatile bituminous coal and anthracite without problem Nielsen et al 1986 On the other hand high volatilelow calorific value alternative fuels have limited use in the kiln primary firing
But increased competition in the cement trade is causing the manufacturer to put forth every endeavour to reduce the cost of production and although at present many proprietors do not see their way to modernized their plants by the adoption of the rotary system yet the day is not far distant when the stationary kiln be it intermittent or
The rotary kiln line raw mill and coal mill were being operated by a PLC based central automation system in the plant In general it is quite difficult to ensure process control with such a conventional automation system looking at long term stability and consistency due to shifttoshift variations
