First, the powder conveying link is prone to powder caking or spilling, and the traditional conveying structure cannot guarantee uniformity of the feed, resulting in uneven calcination in the kiln, affecting the performance stability of the negative electrode material and failing to meet the continuous production requirements. Second, the kiln body is usually placed directly on the ground, and the bottom is easily corroded by ground moisture, shortening the service life of the equipment and increasing the maintenance cost of the enterprise.
