Product Description
Vertical shaft lime kiln is widely used for producing cement for the construction industry. Lime is very important for many other uses and chemical applications, to produce gypsum wallboard or drywall panels, to neutralize toxic chemicals, for air pollution control scrubbing systems, for neutralizing the acidity of soil for agricultural, and Vertical Lime Kilns are used for the production of sugar. Lime is used for pigment in paints. vertical shaft kilns project is consist of 4 parts, raw materials loading system, calcinating system ,lime discharge system ,and exhaust and dust collecting system vertical shaft kilns project is consist of 4 parts, raw materials loading system, calcinating system ,lime discharge system ,and exhaust and dust collecting system.Limestone and coal are transported to the transition silo on the top of the kiln by belt conveyor with scale , unloading car, and the elevator . The distributor on the top of the kiln will distribute the mixed limestone and coal into the kiln to calcine . The lime calcined will be discharged by the ash discharge , then transported to the finished lime silo by the belt conveyor to storage.In the process of calcination, air is blows into the kiln to combustion by the blower . The air with high temperature will preheat the raw materials , then will be discharged into the air after desulfurization and dust collect system by the draught fan. According to the physical and chemical level of the materials and gases in the kiln, the kiln can be divided into 3 zones at the height of the kiln, namely, preheating zone, calcining zone and cooling zone.The preheating zone is located at the upper part of the kiln, which accounts for about 1/3 of the effective height of the kiln.The material in this region (limestone and coal) temperature by preheating from top-down normal temperature to about 900 DEG C,thus burning gas zone rising (kiln gas decreased from 900) up to 120 DEG C when the material after 900. The water in the material is completely evaporated, CaCo3 in the limestone have been the decomposition, the surface began to decompose, all the material and parts of mineral in coal has been broken down, so the area of the material was drying and preheating.The calcination zone is located in the middle part of the kiln body, which is about 1/6 of the effective height of the kiln body.The temperature in the area of raw materials from top to bottom up to about 1200 DEG C, and then decreased from 1200 DEG C to
about 900 DEG C,the limestone is calcinated into lime, the coal calcinated into ash. In this area, the carbon in anthracite mainly reacts with oxygen in the gas to make the calcium carbonate in the limestone ore decompose and produce the finished lime.The cooling zone is located at the lower part of the kiln, which accounts for about 1/2 of the effective height of the kiln. In this area, the finished lime and cinder fall from about 900 to about 60, while the air in the kiln rises from the normal
temperature to about 900 centigrade. To reduce the material from about 900 DEG C to 60 centigrade, carbon remaining can not burn.the calcium carbonate in limestone residual is no longer decomposition, in the cooling process. While the gas in the kiln rises from normal temperature to about 900 DEG C, the main process of gas is preheated.The preheating zone and the cooling zone are all heat exchange zones, and the gas temperature in the preheating zone is too high,and the heat is transferred to the material with low temperature (limestone, raw coal). The material in the cooling zone (finished products, lime and cinder) is high in temperature and transfers heat to the lower temperature gas (air). This will make the
furnace heat efficiency to a higher level.Limestone and coal are transported to the transition silo on the top of the kiln by belt conveyor with scale , unloading car, and the elevator .

The raw lime particles are transported from the quicklime silo to the system, and the design limit is started from the bottom of the storage hopper until the packing system, lime is smaller than 200 meshes. The whole system is equipped with PLC automatic
control and field single equipment control cabinet, the automatic control is divided into three parts, namely the feeding system,the digestion system and the packing system The raw lime particles are transported from the quicklime silo to the system, and the design limit is started from the bottom of

The whole system is equipped with PLC automatic control and field single equipment control cabinet, the automatic control is divided into three parts, namely the feeding system,the digestion system and the packing system.Quick lime is transported by belt conveyor from silo into bucket elevator ,then primary hydration machine to slaker by weight conveyor (note: according to capacity, divided into single, double and three axis), then gets into second hydration machine (note:according to capacity, divided into single, double and three axis), then go to third hydration machine , the quality lime will be sent into the silo for packing in the bags each 20-50kgs per bag by the screw conveyor , the bigger size will be milled by Raymond mill .
Quick lime has chemical decomposition and has been decomposed into Ca(OH)2 (CaO+H2O=Ca(OH)2), then transported into separator(mesh can be adjusted). After getting qualified slaked lime and removing impurity. Qualified slaked slime is transported into bucket elevator, then discharged into finished product hopper.According to customer need, it can packed into tank truck or bags. The pollution of whole project is solved by pulse jet dust collector, collecting efficiency is 99.5%, which accords with environmental protection and noise criteria.Quick lime is transported by belt conveyor from silo into bucket elevator ,then primary hydration machine to slaker by weight conveyor (note: according to capacity, divided into single, double and three axis), then gets into second hydration machine (note:

Advantage Of Ours Kiln:
1.Rotate to distribute raw materials evenly,so it can calcining evenly,to improving the quality of finished products.
2.The floor area is small and the sealing is good. It can effectively avoid the exhaust of thermal waste gas without environmental pollution.
3.Rotary discharge, increase stability, to avoid the loss of heat.
4.The temperature and output can be adjusted freely
5.Automatically control the best air distribution and reduce the incomplete combustion loss of fuel.
6.the automation level is high. The adjustment, control and alarm of operation of production system are centralized controlled by PLC in the main control room, with few on-site operators and high labor efficiency.
7.We have 30 years experience in the production of lime production equipment. There are numerous successful cases at home and abroad. The quality is assured and the service is satisfactory.
Working Principle
Large 1,000+ ton/day capacity Vertical Lime Kilns are possible, are very energy efficient and easy to operate. Minimal maintenance is required, because the limestone is brought to the top and into the kiln. Then the limestone is burned (calcined) for a specified time of hours to produce powdered lime. Then the lime is withdrawn at the bottom of the vertical kiln.
The withdrawal at the kiln bottom regulates the gravity flow of limestone and controls the calcining retention time in the kiln. A clinkergrinding mill grinds any remaining chunks of limestone into powder. The lime is then transported by truck trailers or by rail cars. White cement is now very much in demand by the construction industry.
Abroad Installation
The installation quality of the kiln will affect the kiln's working life and the quality of the finished lime. We will dispatch engineers to install on site, including follow-up commissioning and training.
Certifications
Packing And Shipping
The shaft kiln's parts are relatively large and good packaging and shipping are necessary to ensure product transportation safety and reduce freight costs.
