1. Introduction of Rotary Cooler:
The single-cylinder rotary cooler is a device that fully heats the high-temperature materials with the air through the rotating cylinder, and cools the materials. It has good cooling effect, large production capacity, high operation rate, energy saving and environmental protection, simple operation and maintenance, and long life of the whole machine. And other characteristics, can be widely used in cement, lime, ceramsite, metal magnesium and other fields.
2. Working Principle of Rotary Cooler:
The high-temperature material enters the cooler through the feeding device. Because the cylinder is slowly rotating in an inclined state, the material moves from the high end to the low end in the axial direction. During the movement, the lifting plate continuously moves the material upward in the circumferential direction. Lifting, throwing and moving downwards, so that the high-temperature materials and the air are fully heat exchanged until they are cooled below the specified temperature, and the cooled materials are discharged from the discharging device.
3. Rotary Cooler Structure:
The single-cylinder cooler is mainly composed of transmission device, supporting wheel supporting device, supporting wheel supporting device, cylinder, kiln head, kiln tail and sealing device. The main structural features are:
3.1 The equipment has 2 to 4 fulcrums (mostly 2 to 3 fulcrums), it is easy to ensure that the contact surface of the supporting roller and the kiln tyre is parallel to the axis of the cylinder during installation;
3.2 The supporting device adopts rolling bearings, which greatly simplifies the supporting structure of the supporting roller, which can reduce the useless power loss during the operation of the kiln, and also make the maintenance and repair more convenient;
3.3 The kiln head and kiln tail are sealed with heat-resistant steel flake seals instead of the old-fashioned labyrinth seal, which makes the sealing performance better, higher reliability, longer service life, and extremely convenient replacement;
3.4 There is a certain gap between the tyre belt and the cylinder body to ensure that the tyre belt is tightened on the cylinder body to strengthen the cylinder body under normal working conditions;
3.5 The transmission system adopts new AC frequency conversion speed regulation technology, which is more energy-saving and environmentally friendly than traditional electromagnetic speed regulation and DC speed regulation, and has a large speed regulation range, high efficiency, high speed regulation accuracy, and stable operation.
4. Features of Rotary Cooler:
4.1 The frame of the supporting wheel supporting device and the supporting wheel supporting device are welded as a whole, and subjected to vibration aging treatment to eliminate welding stress, and then integrated processing and manufacturing with a large vertical lathe and boring and milling machine to ensure the processing and coordination of each part Accuracy and shape tolerance effectively improve the installation accuracy and reliability of the whole machine;
4.2 Good cooling effect, large capacity, and high operation rate;
4.3 The multiple-angle circumferential lifting plate combination device can greatly increase its heat exchange rate and shorten the cooling time;
4.4 Compact structure, stable operation, easy operation and maintenance.
5. Applicable Materials for Rotary Cooler:
Cooling of materials in power, chemical, metallurgy, building materials, light industry, mining and other industries.
5.1 Calcined limestone
5.2 Calcined dolomite
5.3 Oil fracturing proppant ceramsite sand
5.4 Clay ceramsite for construction
