Vertical Kiln Vertical Rotary Kiln Vertical Lime Kiln Calcining Rotary Kiln

Vertical Kiln Product Introduction

After the qualified raw materials and solid fuel are evenly mixed according to the proportion, they are sent to the shaft kiln for calcining by the single bucket elevator. After calcining, the finished products are discharged from the bottom of the shaft kiln through the discharge device to the conveyor, and the conveyor will send the finished products to the finished product bin. The hot flue gas produced by calcination is purified by the dust removal system and then discharged into the atmosphere.

1. The mechanized lime kiln is a kind of kiln, which can increase the output by 30% compared with the earth kiln and can be continuously calcined. The lime kiln is distributed by the upper part. The central calcination section, the lower rotary discharge section and the transmission part are composed of steel shell structure.
2. Double-layer masonry of high aluminum refractory brick and clay refractory brick is used in the kiln, and lightweight heat-resistant concrete is cast between the masonry and the steel shell. In particular, aluminum silicate heat-resistant fiber felt is lined between the high-temperature calcination belt, kiln lining and lightweight heat-resistant concrete injection layer, which further improves the heat preservation effect and reduces the coal blending ratio, thus saving energy.
3. The key is the use of rotary large tooth block unloading tower, high-pressure centrifugal fan at the bottom of the ventilation forced ventilation, with many tuyres on the unloading tower uniform ventilation, uniform calcination, increase the activity of finished lime, transmission adopts shaft support structure, gear drive, fully able to withstand the kiln height of 17-27 meters within the weight of the material, smooth transmission,
4. It is a mechanized furnace equipment that is currently being promoted and used, which can be used for calcination of ordinary building lime, calcination of activated lime with deslagging in iron and steel plants, and calcination of raw materials of calcium hydroxide, calcium carbonate and nano-calcium in chemical industry.

Vertical Kiln Structure
1. Kiln body: the main part of the shaft kiln, which is provided with refractory lining and multi-layer grate.
2. Feeding and discharging device: located at the top and bottom of the kiln, respectively responsible for adding raw materials to the kiln and discharging clinker from the bottom of the kiln.
3. Ventilation equipment: to ensure the supply of air required for combustion in the kiln and the discharge of combustion products.
