Lithium ore rotary kiln product introduction

Lithium ore rotary kiln is a thermal equipment for heating loose, powder or slurry materials. It is widely used in the roasting of lithiumite, spodumene, lithiumite, lithiumite and iron lithiumite raw materials. According to the characteristics and production capacity of each lithium concentrate raw material, it can be customized.

Outstanding advantage

1. The cylinder design fully considers the Angle of the cylinder deflection support, extending the life of refractory brick and castable; Guarantee the material calcination conversion rate, spodumene calcination transformation rate can reach more than 98%, lithiumite calcination transformation rate can reach more than 85%.

2. Adopt large diameter and small length-diameter ratio bearing to improve reliability. The bearing is automatic aligning bearing.

3, lithium carbonate rotary kiln is a new type of open gear cover sealing form, sealing effect is good.

4, spring plate laminated flexible seal, double spring plate seal increases the design of thermal insulation layer, help to improve the reliability and service life of lithium carbonate rotary kiln.

Working principle

The rotary kiln is composed of cylinder body, transmission device, support, stop wheel support device, kiln lining, kiln tail seal, kiln head cover and combustion device. The kiln cylinder body is a heated rotating part, made of high quality carbon steel plate coil welding; The cylinder is supported on the support device through the wheel belt, and a mechanical or hydraulic stop wheel is provided on one or several of the support devices to control the axial movement of the cylinder. The transmission device makes the cylinder rotate at the speed required by the process through the tooth ring located in the middle of the cylinder; Due to the need for installation and maintenance, the larger kiln is equipped with an auxiliary transmission device that makes the kiln body rotate at a very low speed. In order to prevent cold air from entering and flue gas and dust from spilling out of the cylinder, reliable sealing devices for kiln tail and kiln head are provided at the feed end and discharge end of the cylinder.
