Introduction of active lime rotary kiln production line:
Active lime production equipment----Lime production line is a
complete set of lime production equipment from feeding equipment,
screening equipment, conveying equipment, calcining equipment, dust
removal and discharging equipment. Rotary kiln calcined limestone
with preheater and vertical cooler meets the production
requirements of high efficiency, energy saving, environmental
protection and high activity. Successful industrial application of
vertical preheating of environmentally friendly and energy-saving
activated limestone. Due to the significant reduction in fuel
consumption and exhaust emissions, coupled with the use of pulse
bag filter to purify exhaust gas, not only the production cost and
energy consumption are greatly reduced, but the emissions during
the calcination process are up to the standard, and the
environmental conditions are basically maintained.
Main advantages of quicklime plant/lime production line
1. With good quality and high output, it is suitable for
large-scale activities and large-scale production of lime
production lines.
2. The production is stable, and all production adopts negative
pressure airflow, which is safer.
3. Simple structure, convenient control, convenient operation and
maintenance.
4. Fine-grade limestone can be calcined, making full use of mine
resources and reducing the loss of raw materials.
5. Low heat consumption per unit product. Installed in the shaft
kiln superheater, limestone with exhaust air temperature is used,
which greatly reduces fuel consumption.
6. It can make full use of industrial waste gas as fuel for burning
lime and reduce costs.
7. The kiln head adopts a vertical cooler integrated kiln head
cover design. The construction area is small, the sealing
performance is good, and the unsystematic discharge of hot exhaust
gas is effectively avoided.
ZK is engaged in technology research and development, engineering
consulting, equipment debugging, engineering contracting and
related technical services in the fields of cement, building
materials, mining, environmental protection, metallurgy, chemical
equipment manufacturing and other fields. Rotary kiln can be
divided into cement kiln, metallurgical chemical kiln and lime kiln
according to different materials. Cement kilns are used to produce
cement clinker, which can be divided into dry method and wet
method. Metallurgical chemical kilns are widely used for magnetic
roasting of lean iron ore in steel mills and oxidative roasting of
chromium and nickel; supporting high alumina ore in refractory
plants; roasting clinker and alumina in aluminum plants, and
roasting chrome ore and chromium powder in chemical plants. Lime
kilns are used for roasting active lime and light roasting dolomite
in steel and ferroalloy plants. Welcome to visit our company and
production workshop, we sincerely look forward to cooperating with
you.
We will provide you with the most suitable product at the most
reasonable price. If you have any needs, please feel free to
