active lime rotary kiln

Notice! Tomorrow, Hongke will also send away a set of active lime rotary kiln (also known as lime rotary kiln) that has completed φ3.6×45m for several months. After months of hard work, the workshop will complete all the customer’s requirements. Henan has been under heavy rain for two days, but it has not affected the sentiments of all employees of Hongke. The employees are satisfied with the satisfaction and confidence of the customers. This is very satisfied with this. Due to the huge size of the rotary kiln, it is a headache for customers during delivery. Nothing matter, macros help you to solve all the troubles, there is no problem that can not be solved in the macro section, because this is the macro section must and should do, the current life, is so comfortable, want to buy rotary kiln equipment customers, do not Hesitate, come and find Macro. Thanks to the customer’s support for Acer for so many years, Acer will do its best to make every device, and there will be new upgrade equipment and product discounts in the future. We look forward to the inspection of our customers.

First, performance characteristics

1, lime lime kiln specifications according to the requirements of the firing system output requirements, and with the combustion conditions, preheater, decomposition furnace, cooling machine configuration and other factors to determine together.

2. The length-to-diameter ratio (L/D) of the preheater kiln and precalciner kiln should be 11-16.

3, preheater kiln high speed should be 2.0-2.5r/min, pre-decomposition kiln high speed should be 3.0-3.5r/min; high speed speed range 1:10. Preheater kiln and precalciner kiln slope should be 3.5%-4%;

4, lime kiln firing zone should have cylinder temperature detection measures.

5. The lime kiln firing belt should adopt forced air cooling.

6. The lime kiln adopts a continuously variable-speed motor, and the main motor of the lime kiln is equipped with an auxiliary drive. The auxiliary drive of the main motor must have a backup power supply.

Second, the working principle of lime rotary kiln

The qualified limestone is placed in the silo and enters the top of the preheater silo under the lifting of the hoist. The top of the preheater silo is controlled by the upper and lower material pull control gauges. The limestone is evenly distributed through the downcast tube. Into the preheater room. The limestone in the preheater is heated to about 900°C by 1150°C kiln flue gas, 3% of which is decomposed, and the limestone is pushed into the rotary kiln by the hydraulic push rod, and the limestone in the rotary kiln is calcined. Decomposes into CaO and CO2. The decomposed limestone enters the cooler and is discharged out of the cooler after the cooled cold air is cooled to 100°C. Heat exchanged hot air at 600 degrees Celsius enters the kiln and mixes with the gas and burns in the mixed gas. The exhaust gas needs to be discharged into the cold air. The exhaust gas enters the bag type dust collector under the guidance of the cooling fan, and the exhaust fan discharges the exhaust gas out of the chimney. After the lime is discharged out of the cooler, it is conveyed into the lime reservoir via a vibrating feeder, a chain conveyor, a bucket elevator, and a belt conveyor. The user decides whether to perform screening or other processes according to his own needs.

Third, the design of lime rotary kiln

1. Lime rotary kiln specifications are determined according to the requirements of the firing system output, and are determined together with factors such as combustion conditions, preheater, precalciner, and cooler configuration.

2. The length-to-diameter ratio (L/D) of the preheater kiln and precalciner kiln should be 11-16.

3, preheater kiln speed should be 2.0-2.5r/min, pre-decomposition kiln high speed should be 3.0-3.5r/min; speed range 1:10. Preheater kiln and precalciner kiln slope should be 3.5%-4%;

4, the rotary kiln firing zone should have cylinder temperature detection measures.

5. The rotary kiln firing cylinder should adopt forced air cooling.

6. The rotary kiln adopts a continuously variable-speed motor, and the main motor of the rotary kiln is equipped with an auxiliary drive. The auxiliary drive of the main motor must have a standby power supply.

IV. Sales case of Hongke active lime rotary kiln:

1. Hongke sent a 600t lime rotary kiln production line to Xianyang, Shaanxi.

2. Chengdu, Sichuan Province introduced Hongke Company to burn 500m3 limestone crushing-drying-rotary kiln equipment.

3. Hebei Handan purchased 850t kaolin rotary kiln equipment when purchasing Hongke.
