Product Description
Product Description
The cement production line is a production line construction project composed of a series of supporting equipment for the production of cement. It is mainly composed of crushing, homogenizing, raw material preparing, drying, preheating decomposition, clinker firing, cooling, grinding, packaging, conveying, environmental protection dust collection and other equipment. Turui company provides process design, civil construction, complete sets of equipment, installation and commissioning, technical and other services.
Process Flow Description
Cement production uses limestone and clay as the main raw materials, which are crushed, batched, and grinded into raw material by raw mill, and then fed into cement rotary kiln for calcination to become clinker, and then add appropriate amount of gypsum to the clinker, add some mixed materials or additives, and grind it into cement by cement ball mill, and then transported out of the factory by a packaging machine or a bulk machine.
At present, cement plants usually adopt the dry process cement production process, which dry and grind raw materials into raw materials at the same time and feed them into a dry rotary kiln for calcining become clinker. The main advantage of dry production is the low heat consumption.
1. Crushing & Proportioning
Primary crushing involves limestone rock fed through large capacity crushers. This reduces the rock to a maximum size of
approximately 150 mm. Secondary crushing further reduces this to 75mm or under. Residule material is stacked and reclaimed with a
bridge reclaimer in a cross section so that the homogeneous limestone is fed further in the process. This averages the limestone
quality.
2. Raw milling & Blending
Crushed particles are ground to 90 microns or less in a closed circuit ball mill with high efficiency separator. The raw meal is
transferred to continuous blending silos (CFC) for homogenization ,extracted by load cell hopper for feeding to the kiln pre
heaters.
3. Pyro processing
Raw material is heated to over 1,450 °C in a pre-heater tower,then through a pre-calciner and finally to the rotary kiln.
4. Burning
As the material progresses through the kiln, certain elements areremoved in the form of gases. The remaining elements unite to
form a new substance (clinker) with new physical and chemical characteristics. Clinker is formed in small marble sized pieces.
5. Cooling
Clinker is discharged from the kiln and the temperature is reduced in grate coolers. The hot air from the coolers is redirected
back to the kiln, this saves fuel and increases burning efficiency.
6 . Milling, Storage & Packing
Portland cement, the basic ingredient of concrete, is a combination of calcium, silicon, aluminum, iron and small amounts of other
ingredients to which gypsum is added in the final grinding process to regulate the setting time of the concrete.
