1. Introduction of the rotary cooler:

A single cylinder rotary cooler is a device that completely heats high temperature materials with air through a rotating cylinder and cools the materials. It has good cooling effect, large production capacity, high productivity, energy saving and environmental protection, easy operation and maintenance, and a long service life of the whole machine. And other characteristics, can be widely used in cement, lime, expanded clay, metal magnesium and other fields.

2. The principle of operation of a rotary cooler:

The high temperature material enters the cooler through a feeder. As the cylinder rotates slowly in a tilted state, the material moves from the top end to the bottom end in the axial direction. During movement, the lifting plate continuously moves the material up the circumference. Lifting, throwing and moving down, so that high temperature materials and air are fully heat exchanged until they cool below the set temperature, and the cooled materials are discharged from the unloading device.

3. Rotary cooler design:

The single-cylinder cooler mainly consists of a transfer device, a support device for a support wheel, a support device for a support wheel, a cylinder, a furnace head, a furnace tail, and a sealing device. Main design features:

3.1 The equipment has 2 to 4 points of support (usually 2 to 3 points of support), it is easy to ensure that the contact surface of the support roller and the kiln tire is parallel to the cylinder axis during installation;

3.2 The support device uses rolling bearings, which greatly simplify the support structure of the support roller, which can reduce unnecessary power losses during furnace operation, and make maintenance and repair more convenient;

3.3 The furnace head and furnace tail are sealed with heat-resistant steel plate seals instead of the old-fashioned labyrinth seal, which improves sealing performance, increases reliability, increases service life and is extremely easy to replace;

3.4 There is a certain clearance between the tire belt and the cylinder body to provide tension on the tire belt on the cylinder body to reinforce the cylinder body under normal operating conditions;

3.5 The transmission system adopts the new AC frequency conversion speed control technology, which is more energy-saving and environmentally friendly than the traditional electromagnetic speed control and DC speed control, and has a large speed control range, high efficiency, high speed control accuracy and stability. ... operation.

4. Features of the rotary cooler:

4.1 The support wheel frame and the support wheel support device are welded as one piece and subjected to vibration aging treatment to eliminate welding stress, and then machining and production on a large vertical lathe and boring mill are integrated to ensure that every part is machined and matched. shape tolerance effectively improve the installation accuracy and reliability of the whole machine;

4.2 Good cooling effect, large power and high working speed;

4.3 The combined device with multi-angle annular lifting plates can greatly increase the heat exchange rate and shorten the cooling time;

4.4 Compact structure, stable performance, easy operation and maintenance.

5. Applicable materials for rotary cooler:
