cement plant introduction

Rotary kiln is also known as rotation kiln. There are many kinds of rotary kiln produced by our company,according to applicable industries, it is divided into metallurgical rotary kiln and chemical rotary kiln; According to the applicable materials, it can be divided into cement rotary kiln, lime kiln, ceramic sand rotary kiln, metal magnesium rotary kiln, bauxite kiln etc.The rotary kiln is composed of barrel, supporting device, catch wheel supporting device, transmission device, movable kiln head, kiln tail sealing device, and coal injection pipe device.

Rotary kiln cylinder composed of steel plate, cylinder body with build by laying bricks or stones of refractory lining, and horizontal line into slope, three belting leather in each block supporting device, in the material near the end belting leather across the inner cylinder with tangential spring plate fixed on a big gear ring, which is a small gear meshing.During normal operation, the main drive motor is transmitted to the open-type gear device by the main drive motor, which drives the rotary kiln.Materials are calcined from the end of the kiln.Due to the effect of tilting and slow rotation of the cylinder, the material is along the circumference of a circle and tumbling along the axial direction (from high to low) mobile, continue to complete the process, and generate the clinker kiln hood into the cooling machine cooling.The fuel is sprayed into the kiln by the kiln head, and the waste gas and materials produced in the furnace are exchanged for impact crusher, which is exported by the kiln tail.This design does not contain fuel burner.


Simplified description of the process

² 1.1..1 Limestone crushing and transportation

Trucked to the site from the its mine, limestone is directly discharged at an exclusive tipple, and crushed in the single-stage hammer crusher via heavy-duty plate feeder .When the crusher is off, limestone is kept in exclusive pile, later sent to crushing system

² 1.1..2 Limestone pre-blending & transportation

Crushed limestone is to be stored in the round preblending stockpile,and storage life of 3.74days. the crushed limestone will be continously piled through cantilever stacking belt conveyor in chevron shape,and then transversely reclaimed by scrapper reclaimer.the limestone after preblending will be conveyed to raw material proportioning station by belt conveyor.

² 1.1..3 Clay & Marl crushing and Iron powder transportation

Trucked to the site from the its mine, clay and marl directly discharged at an exclusive tipple, and crushed in the crusher via medium plate feeder .When the crusher is off, clay is kept in exclusive pile, later sent to crushing tipple by frontloader. After crushing, the clay and marl then be sent to the Accessory Raw Material Preblending shed by belt conveyors.

The Iron powder with particle size £25mm is discharged from automatic dump truck into hopper. Then be sent to the Accessory Raw Material Preblending shed by belt conveyors.

² 1.1.4 United Preblending Shed & Transportation

Crushed clay, marl and Iron powder carried to Accessory Raw Material Preblending Shed by belt conveyor to stored. United preblending stockpile consists of auxiliary preblending stockpile and raw coal preblending stockpile. The United Preblending Shed is a longitude stockpile.

² 1.1..5 Raw material proportioning & transportation

Raw meal proportioning shall employ four silos, and weighing belt of frequency control. The proportioning silo of limestone is of φ8m steel bin , while clay, marl and iron powder proportioning silo is of steel bin.

² 1.1..6 Raw mill & waste gas treatment at kiln inlet

After meeting the requirements of grindability test, raw meal shall enter into vertical mill made in China.

² 1.1.7. Raw meal blending silo & kiln inlet feeding

Raw meal from raw mill is to be stored in IBAU silo, impact flow meter shall be employed at kiln inlet feeding, and raw meal is to be carried into pre-heater system by belt type bucket elevator

² 1.1.8 Kiln pre-heater & pre-calciner system

Kiln inlet employs single line 5 stage cyclone pre-heater and KSF calciner.

² 1.1.9 Calcining kiln & kiln outlet

After pre-calcining processing, raw meal is calcined into clinker in rotary kiln , with heat consumption as 760kCal/kg-cl. High temperature clinker from rotary kiln is to be cooled sharply by cold air blown in below from grid plate in grate cooler. The temperature of clinker from grate cooler is ambient temperature + 65℃, cooled and crushed clinker is taken into clinker silo by bucket chain conveyor.Part of high temperature exhaust gas from cooler shall become secondary air; other part shall become combustion air in calciner via tertiary air duct; and part of it shall become drying source for coal grinding in coal mill; and the rest shall be released into the atmosphere after the treatment of kiln outlet bag filter. Fine ash from heat exchanger and bag filter shall be carried into clinker silo via chain conveyor and clinker bucket chain conveyor.

² 1.1.10 Clinker storage & transportation

The cooled and crushed clinker through chain bucket conveyer comes to clinker silo for storage, with capacity of 33000t, and storage life of 16.5 days. The clinker out of silo is sent to the clinker batch silo before cement mill by belt conveyor.

² 1.1.11 Gypsum crushing and pozzolana transportation

The gypsum and pozzolona is transported to crusher for crushing .When the crusher is off, gypsum is kept in exclusive pile, later sent to crushing tipple by frontloader. After crushing, the gypsum then be sent to the batch silo by belt conveyors.

Trucked to the site from the its mine, pozzolana directly discharged at the additives shed. Then it is conveyed via forklift to specific unloading pit and via belt conveyer sent to proportioning silo.

² 1.1.12 Cement proportioning and grinding

Cement proportioning shall employ threeφ8m silos, and weighing belt of frequency control.

Cement mill has two sets of circulating system. The ground cement will go through chute and elevator, then be directly sent to Φ15m cement silos.

² 1.1.13 Cement storage and bulking

Cement from cement mill system is stored in four silos , two of them equip bulk loading system. Cement is carried to packing system from the silo bottom. The storage capacity for one cement silo is 8700t.

² 1.1.14 Cement packing

Cement from bottom of silos is lifted by the bucket elevator. Packing shall employs rotary packer with 8 mouths, and cement bagged are transported by belt conveyor to bag cement truck loader system. There are four belt-loaders in truck loader system,for packaged truck loading.

² 1.1.15 Raw Coal Crushing&Transportation

Trucked to the site from the its mine, coal directly discharged at an exclusive tipple, and crushed in the crusher via medium plate feeder .When the crusher is off, coal is kept in exclusive pile, later sent to crushing tipple by frontloader. After crushing, the coal then be sent to the raw coal Preblending shed by belt conveyors.

² 1.1.16 Pulverized coal preparation and weighing system

Raw coal after measuring of belt scale is fed into air swept mill for drying and grinding. The hot air for drying is exactly the exhaust gas from kiln outlet grate cooler. Discharged coal powder will be collected by specific high concentrated anti explosive bag filter, the collected powder then enters pulverized coal bin, through 2 measuring systems, which will be sent to multichannel coal burner pipe at kiln outlet and coal burner pipe at kiln inlet calciner. The dusty gas is purified by bag filter and then ejected to atmosphere.

² 1.1.17 Compressed air station

There are two air compressor stations in the site, that is, 6 sets of screw air-boosting compressor in all of 23m3/min as displacement and the pressure is 0.8Mpa. One air compressor station is set below the kiln pre-heater frame with 3 sets screw air-boosting compressor, the other which is near the proportioning silo of cement mill shop can meet the demands of every pneumatic valve, kiln pre-heater block-up, measuring device and pulsed bag dust collector and so on.
