Cement Production Bring Wealth

According to the business daily reported that Nigeria has surpassed South Africa, will become the largest cement producer in sub-saharan Africa; At the same time, Nigeria is also a third largest cement producer in the Middle East, second only to Egypt, Saudi Arabia.In 2013, 18.3 million tons of cement production by 2012, to 28 million tons.In Nigeria economy continues to improve, increasing housing and infrastructure investment and policy support, Nigeria’s cement output of 2017 is expected to reach 50 million tons.Can say Nigeria cement industry is very good, also reflect the profitability of listed companies in Nigeria, Dangote group, Lafarge group (Lafarge), Ashaka company, northern cement company (CCNN) average earnings increase rate of 50.2%, higher than the average 36.6% of the listed company’s stock exchange earnings growth level.

2500T/d Dry Process Cement Production Of Major Equipment

To do a good job, must first sharpen his device. To produce high quality cement, it must have a full set of equipment, the perfect equipment. A complete cement production line needs dozens of equipment, including:

  • Raw material crushing equipment:1.limestone plate feeder, located within the limestone crushing plant for limestone feed; 2.limestone crusher for crushing limestone, limestone crushing plant located in the plant, crushing type is a single-stage hammer crusher.
  • Raw material production equipment: 1.vertical mill and a ball mill for grinding materials; 2.separator for selecting qualified subdivision; 3.kiln bag filter for kiln and raw mill exhaust. capture the raw material powder; 4.kiln bag filter exhaust fan for raw mill and kiln exhaust gas treatment system; 5.raw mill circulating fan, located behind the preheater tower humidifier back for draw cited preheater exhaust.
  • Clinker production equipment: 1. The storage bucket elevator, used for raw materials into the Treasury;2. Into the kiln bucket elevator, used for raw materials entering the preheater;3. Grate cooler cooling fan, used for grate cooler waste gas to wind, decorated around the grate cooler;4. The electric dust collector at kiln head, located in the cooling machine, electric dust collector at kiln head behind the front of exhaust fan, used to deal with the remnants of kiln head grate cooler.5. Electrical dust collector at kiln head exhaust fan, cooling machine is used to take out waste gas, gas after purification by electric dust collector at the back.
  • Cement grinding equipment: 1. The roller press and ball mill, used for cement squeezing grinding;2. The classifier, dispersion of static classification with roller press equipment;3. Choose powder system, circulation fan ventilation system used for classifier;4. Cement mill finish bag dust collector, used for cement mill dust exhausting.

Cement Production Process

Crushing process: cement production process, a large part of the raw material to be broken, such as limestone, clay, iron ore and coal, etc.Because the limestone is one of the largest raw material consumption in the process of production, out of the ground after the larger particles, hardness is higher, so the limestone crushing in cement material crushing occupies more important position.The limestone by crusher in primary and secondary crushing, break into 20 mm.

Raw material pre-homogenization process: raw prehomogenization prehomogenization technology is in the presence of raw materials, to take the process of applying scientific stacker reclaimer technology to achieve the initial homogenization of raw materials, along with the raw material storage yard and were of the function.

Raw preheating decomposition: preheating and part of the raw meal decomposition are done by preheater, slurry is able to discharge of hot gas well blended with stove, gas increases the contact area, heat transfer speed, high heat exchange efficiency, improve production efficiency, reduce the clinker calcining kiln system heat loss.

Cement clinker burning: raw material in the rotary kiln further decompose rapidly and in a series of solid phase reaction, generate minerals such as in the cement clinker.Clinker burning, temperature began to reduce.Finally by the cement clinker cooler high temperature clinker discharged to rotary kiln cooling to the downstream conveyor, storage library and cement machinery can withstand temperature, recovery of high temperature clinker sensible heat at the same time, improve the thermal efficiency of the system and quality of clinker.

Cement grinding powder: cement machinery is the end of the cement manufacturing process, is also the most power consumption process.Its main function is to cement clinker (and gelling agent, performance adjustment material, etc.) grinding to appropriate particle size (such as fineness, specific surface area), to form a certain grain size distribution, increase its hydration area, accelerate the hydration speed and satisfies the requirement of setting and hardening cement paste.
