A crushing and screening integrated machine for fertilizer production line

Abstract

The invention discloses an integrated crushing and screening machine for fertilizer production lines. The limit grooves are set at the top and bottom ends of the discharge port, and the sifting device is set on the discharge port and is engaged with the limit groove. Set at the bottom end of the screen, the present invention is provided with an ejector pin at the top of the screen, and the volute is driven by a motor, so that when the volute rotates, the protruding part is abutted against the ejector pin to move the ejector pin downwards, and at the same time when the volute is rotated, the ejector pin is moved downward. After the protruding point rotates, the ejector pin will usher in a step of the volute plate, so that the ejector pin will rebound, thereby disturbing the screen and flattening the material at the bottom of the screen to prevent the particles from accumulating on the top of the screen. It will be driven by the crushing knife for further crushing to ensure the uniformity of the finished product.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to an integrated crushing and screening machine for fertilizer production lines. Background technique [0002] In the process of fertilizer production, it is necessary to use crushing equipment to crush the raw materials, and then by using a suitable size screen, the crushed materials can be discharged after reaching the screen size, thereby achieving the effect of integrated crushing and screening; [0003] When the material moves in a circular motion with the crushing knife in the crushing bin, some particles of the right size will be blocked at the place where the bottom of the screen meets. The particles will accumulate here, causing the screen to be partially blocked. At the same time, the particles on the top will be driven by the crushing knife for further crushing, which will affect the uniformity of the finished product. SUMMARY OF THE INVENTION [0004] In view of t...

Problems solved by technology

[0003] When the material moves in a circular motion following the crushing knife in the crushing chamber, some particles of the right size will be blocked at the junction of the bottom of the screen, which is also the place where the material is directed by the tangential force of the crushing knife, making more Particles will accumulate here, causing partial blockage of the screen. At the same time, the particles on the top of the accumulation will be driven by the crushing knife for further crushing, which will affect the uniformity of the finished product.
