This cement production line adopts a new dry cement preparation process, which is mainly composed of crushing and pre-homogenization, raw material preparation homogenization, preheating decomposition, cement clinker clacination, cement grinding, packaging and other processes. The raw materials are dried and ground at the same time, or dried first and then ground into raw powder, and then feed the raw powder into the cement rotary kiln to calcinate the mature material. Then the clinker and an appropriate amount of gypsum (sometimes also mixed materials or admixtures) with MBS rod mill grinding fine.

Cement equipment list

In this cement plant project, the required cement equipment including cement rotary kiln, cement ball mill, cyclone preheater, grate cooler, dryer, conveyor and etc.

  1. limestone crushing dump truck will pour limestone into the hopper, broken by the hammer crusher, by the belt conveyor to the limestone pre-homogenization yard, the use of cantilever stacker for layered stacking to take material. The extracted limestone is delivered by belt conveyor to the limestone mixing bin of the raw material batching station. An electromagnetic iron remover is provided on the inbound belt conveyor to remove possible iron parts from the limestone. A metal detector is provided at the head of the belt conveyor to detect whether there are any remaining iron parts in the raw material, so as to avoid damage to the raw material grinding roller press. The raw material mixing station is equipped with limestone, clay and other mixing silos. A plate feeder and a quantitative feeder are arranged at the bottom of each distribution bin. Four kinds of raw materials are discharged by their respective quantitative feeder according to the proportion required for batching, and the mixed materials are fed into the raw material vertical mill by belt conveyor.
  2. the raw material grinding using vertical roller grinding system, the use of high temperature exhaust gas discharged from the kiln tail as the drying heat source. After the material is pulverized by vertical grinding, it is dried and graded by V-type powder separator. After the fine powder is selected by high-efficiency powder separator, some fine powder is sent to the raw material homogenization warehouse by air conveyor chute and bucket elevator.
  3. the coal mill is set at the end of the kiln, and part of the exhaust gas at the end of the kiln is collected by the cyclone dust collector, which is used as the drying heat source of the raw coal. After humidifying and cooling from the humidifying tower, the exhaust gas at the end of the kiln directly enters the electric dust collector at the end of the kiln. The water spray of the humidifying tower is automatically controlled according to the exhaust gas temperature at the exit of the humidifying tower, so that the exhaust gas temperature is within the permissible range of the electric dust collector at the end of the kiln. The exhaust gas after purification by the dust collector is discharged into the atmosphere by the exhaust fan. The kiln ash collected by the humidification tower is sent to the kiln feeding system or raw material homogenization warehouse through the conveying equipment. A continuous raw material homogenization warehouse is set up, and the raw material in the warehouse is aerated by alternating zones and discharged from the surrounding ring area to the mixing chamber, where the raw material is aerated and stirred evenly. The required basement inflation is supplied by the configured Roots fan. After metering, the homogenized raw powder is transported by air to the chute and bucket elevator, and then fed into the two feed ports of the double series preheater through the feed valve and the air lock valve respectively.
  4. The firing workshop is composed of five-stage double-series suspension preheater, decomposition furnace, rotary kiln, grate cooler and corresponding dust removal system, with a daily output of 2500t cement clinker. The raw material fed into the preheater is preheated by the preheater and decomposed in the decomposition furnace, and then fed into the kiln for calcining. The high temperature clinker out of the kiln is cooled in the grate cooler. After the large clinker is broken by the crusher, it is collected together with the small particles of clinker that leak to the air chamber and sent to the clinker warehouse for storage by the clinker chain bucket conveyor. The hot air passing through the clinker bed in addition to providing high temperature secondary air and tertiary air to the kiln and decomposing furnace, the waste gas is purified by the electric dust collector and discharged into the atmosphere by the exhaust fan. After the clinker is discharged by the discharging device at the bottom of the warehouse, it is sent to the truck bulk station by belt conveyor, and the clinker transported in bulk is loaded directly into the car through the dust-free bulk head located at the bottom of each warehouse.
  5. Pulverized coal is prepared by grinding system, and the high-temperature exhaust gas discharged from the kiln tail is used as the drying heat source. The raw coal is fed into the coal mill by the quantitative feeder under the original coal bunker for drying pulverization. The pulverized coal enters the bag dust collector with the air flow, and the qualified pulverized coal is collected and sent to the pulverized coal bin with load sensor by the screw conveyor. The pulverized coal is measured and sent to the kiln head burner and the kiln tail decomposer respectively for combustion. The dust-containing gas is purified by the anti-static bag dust collector and discharged into the atmosphere by the exhaust fan. Pulverized coal bin and bag type dust collector are equipped with CO detector device and explosion-proof valve. A central laboratory is set up in the whole plant, which is responsible for the inspection of raw fuel, semi-finished product and finished product. An air compressor station is set up to supply compressed air for the whole plant.
  6. Cement ingredients are used in the grinding bin, the mill is selected with φ3.2×13 meters cement mill, and the roller press is matched according to the situation to achieve a cement output of 180 t/h. The finished cement is pneumatic transported to the original cement warehouse by the double bin pump.
  7. There are four φ12×42m round warehouses for cement storage, with a total reserve of 20000t and a storage period of 4.6d. The finished cement from the cement grinding system is pneumatic transported to the cement storage system. The cement warehouse is equipped with a discharge and decompression conical chamber and an inflating device. The air source for inflating is provided by Roots blower. Cement packaging workshop is equipped with two eight-nozzle rotary packaging machines, a single output of 90 ~ 100t/h.

why choose us

cement plant project
  • Reduce energy consumption: The cement production line configured by our company, its production capacity can undertake the production of complete sets of dry cement with a daily output of 1000t/ D-10000t /d, which can reduce the power consumption rate by 20%-30%, directly reduce the production cost, win profits for customers, and improve the comprehensive benefits of the enterprise. In addition, a reasonable choice of production process is a great significance to reduce energy consumption.
  • improve production: the whole cement production line runs smoothly, the structure is strong, not only can reduce maintenance costs, but also in the production efficiency is considerable. According to statistics, 1 ton of Portland cement in the process of grinding at least 3 tons of materials, the power needed to consume about 60% of the power of the whole plant, of which raw material grinding accounted for 30%, cement grinding accounted for about 40%, it can be seen that the production efficiency is better.
