Pubdate:2022-11-15 16:08:00

The rotary kiln is composed of a cylinder, a transmission device, a supporting device for the support of the support and retaining wheel, a seal for the kiln head and tail, a kiln head cover and a combustion device, as shown in the figure below.

The kiln shell is a heated rotary part, which is made of high-quality killed steel plate by rolling welding. The shell is supported on the supporting device of the sliding bearing of the 2nd~7th gear through the wheel belt, and mechanical or hydraulic blocking wheels are set on one or several of the supporting devices to control the axial movement of the shell; The transmission device rotates the cylinder at the required speed through a gear ring arranged in the middle of the cylinder; Due to the needs of installation and maintenance, the larger kiln is equipped with an auxiliary transmission device that makes the barrel rotate at a very low speed; In order to prevent cold air from entering and smoke and dust from overflowing the cylinder, reliable sealing devices for kiln tail and kiln head are set at the feeding end (tail) and discharging end (head) of the cylinder
