[0002] In the production process of ceramic heating elements, the raw materials need to be processed by a spray granulation device. According to the patent authorization announcement number: CN209020345U, a spray granulation device for the production of PTC thermistor ceramic heating elements is disclosed. This utility model relates to a spray granulation device for the production of PTC thermistor ceramic heating elements, which includes a granulation chamber. The granulation chamber is equipped with a guide plate, the upper end of which is fixed to the top surface of the granulation chamber and divides the interior of the granulation chamber into two areas connected at the bottom. The top of the granulation chamber is equipped with a feed pipe and an air inlet pipe, which are respectively set on the top of the granulation chamber corresponding to the areas on both sides of the guide plate. A rotating mesh plate is provided in the internal area of ​​the granulation chamber below the feed pipe. The rotating mesh plate is composed of multiple metal mesh plates evenly distributed on a rotating shaft, which is driven by a motor.

[0003] However, in existing technologies, the granulated particles have varying diameters after raw material granulation, requiring subsequent screening. This increases the number of steps in the production process, impacting processing efficiency. Furthermore, powder adsorbed on the particle surface during granulation cannot be effectively recovered, leading to powder accumulation at the bottom of the device and hindering cleaning. Therefore, improvements to the existing technology are necessary. Utility Model Content
