AI Technical Summary
Existing grinding equipment is prone to feed blockage due to the hygroscopic nature of the curing agent during the grinding process, which narrows the feed channel and affects the smoothness of the feed.
Heating coils are used to heat and evaporate moisture from the feed cylinder, combined with the forced conveying by the rotation of auger blades, to prevent the curing agent from accumulating and adhering in the feed cylinder and to ensure smooth feeding.
This effectively avoids feed blockage caused by the curing agent's hygroscopic clumping, ensuring that the curing agent enters the grinding chamber smoothly and guaranteeing the stability and smoothness of the feeding process.

[0021] Specifically, the solidifying agent to be ground is placed in the feeding hopper 21, under the action of gravity, the solidifying agent flows into the feeding cylinder 2 from the feeding hopper 21, the motor 23 is started to drive the transmission shaft 24 and the screw blade 25 to rotate, the screw blade 25 has a specific spiral shape, when it rotates, a forward thrust is generated on the solidifying agent in the feeding cylinder 2, the thrust makes the solidifying agent move along the spiral direction of the screw blade 25 from one end of the feeding cylinder 2 to the other end, under the continuous pushing of the screw blade 25, the solidifying agent can be smoothly conveyed from the feeding cylinder 2 into the sieve cylinder 13.
[0022] The rotation of the screw blade 25 not only realizes directional conveying of the solidifying agent, but also preliminarily stirs and disperses the solidifying agent to a certain extent, thereby avoiding the accumulation or blockage of the solidifying agent in the feeding cylinder 2 and ensuring the stability and continuity of the feeding process.
[0023] Please refer to Figure 2 , a ring-shaped heating cavity 22 is arranged in the wall of the feeding cylinder 2, a heating coil 221 is arranged around the heating cavity 22, and the heating coil 221 is electrically connected with an external power supply through an electric wire.
