Rotary drum drying equipment is a highly mechanized calcination machine with low resistance to fluid passing through the cylinder, low energy consumption, and strong adaptability to materials.

According to the requirements of calcination, the raw material is fed into the drying equipment from one end, and under the flipping of the evenly distributed plate in the inner cylinder, the material is evenly distributed and separated in the drying equipment, and fully contacts with the high-temperature flue gas to decompose the water adsorbed on the surface of the phosphate iron powder. The decomposed water vapor flows out through the dehumidification fan to meet the drying requirements. Then it is made into anhydrous iron phosphate (containing 2 crystal waters). In the calcination process, the material stays in the kiln for a period of time under the action of a sloping cylinder and a plate, and moves to another section of the calcination kiln where the finished product flows out. The internal crystal water migrates out under temperature and time control and is collected by a first stage bag to ensure the recovery of smoke and dust. The heat generated by the combustion of natural gas is used as the heat source for the drying equipment, which can more fully improve the heat utilization efficiency.

The calcination kiln, also known as the rotary kiln, consists of a kiln tail cover, simplified structure (including transmission device, supporting wheel device, and blocking supporting wheel device), sealing device, kiln head combustion chamber, combustion system (including control system), and exhaust gas treatment system

Main structure of calcination kiln:

Kiln head section

The kiln head is the discharge part of the rotary kiln, with a diameter higher than that of the rotary kiln. It is sealed by stainless steel fish scales and the kiln body. The main components include the inspection port, coal injection nozzle, low carriage, observation hole, etc.

Kiln body part

It is the main body of a rotary kiln (rotary kiln), usually 30-150 meters long, cylindrical, with 3-5 rolling rings in the middle. The cylinder body is often processed into 3-10 sections by the factory, transported by heavy-duty trucks to the destination, and welded together. The rolling ring part, also known as the tire ring, is cast from molten steel, and the rolling ring part of the kiln body is slightly thicker than the steel plate of other parts due to its load-bearing capacity. Supporting the tugboat, it is also a part of the kiln body and connected to the foundation corresponding to the rolling ring, and is the load-bearing pillar of the entire rotary kiln. Usually, a set of rollers consists of two rollers and two pulleys. During normal operation, refractory bricks should be laid inside the rotary kiln.

Kiln tail section

The tail part of the kiln is also an important component of the rotary kiln, with a shape similar to the lid of a rotary kiln at the feeding end, mainly responsible for feeding and sealing.

Rotary kiln support frame

1. The support frame of the rotary kiln can make our rotary kiln machine more sturdy, preventing it from shaking during operation and ensuring stable production;

2. The support frame of the rotary kiln is mainly used to fix our rotary kiln machine, which can prevent deformation of our rotary kiln machine when it is used. Gao Jia is aware that if the rotary kiln machine is not operated properly, it will deform, so it has this function;

3. The rotary kiln bracket can facilitate the lifting and transportation of our rotary kiln machines.

Preheating tower

Also known as a preheater, it is a machine that uses the waste heat from the tail gas flowing out of the rotary kiln to preliminarily heat the material before it enters the rotary kiln. It is mostly a vertical structure. The principle is to use the waste heat from the tail of the rotary kiln to heat the raw materials through a preheating tower that is overfilled with raw materials. Adding a preheating tower can effectively reduce energy consumption and improve the quality level of finished products.

Cooling machine

The cooling machine, in contrast to the preheater, is a device that rapidly cools down the materials in a rotary kiln after firing. It looks like a low profile rotary kiln, but with a lower and shorter diameter, and does not require the laying of refractory bricks. It is replaced by a lifting plate inside. The main function is to quickly cool down the finished product.
