Rotary kiln

The rotary kiln consists of a cylinder, a transmission device, a support, a wheel support device, a kiln lining, a kiln tail seal, a kiln head cover and a fuel device. The kiln cylinder is a heated rotating part, made of high-quality carbon steel plate rolled and welded. The cylinder is supported on the support device through a wheel belt, and a mechanical or hydraulic wheel is provided on one or several gears of the support device to control the axial movement of the cylinder; the transmission device rotates the cylinder at the speed required by the process through the gear ring located in the middle of the cylinder; due to the need for installation and maintenance, larger kilns are equipped with auxiliary transmission devices that allow the kiln to rotate at a very low speed; in order to prevent cold air from entering and smoke and dust from overflowing from the cylinder, reliable kiln tail and kiln head sealing devices are provided at the feeding end and the discharging end of the cylinder.

Product Features

1. Support device: The main shaft structure is adopted, equipped with automatic temperature measurement device and electric heating device, and flow support is available for selection.

2. Wheel stop device: It is divided into mechanical wheel and hydraulic thrust wheel stop. The hydraulic wheel stop device is equipped with a hydraulic control system.

3. Transmission device: It is equipped with single transmission or double transmission. The speed regulating motor DC motor or variable frequency speed regulating motor controls the speed, which is reliable in operation and energy-saving and efficient.

4. Cylinder wheel belt pad: The lower pad of the wheel belt has fixed, adjustable and floating pads, which has the characteristics of simple structure, convenient maintenance and replacement, and no damage to the cylinder body when disassembled and replaced.

5. Sealing device: There are various sealing forms to choose from according to the different designs of the kiln type. Cylinder compression end face seal, spring compression end face seal, heavy hammer graphite block seal, spring graphite block seal, fish scale labyrinth seal, axial labyrinth seal and the above-mentioned combination seal, etc., which are characterized by strong adaptability to the movement and swing of the cylinder body and good sealing effect.

6. Dense hood: fixed and movable
