Abstract

The invention discloses a smashing and screening device for compound fertilizer production. The smashing and screening device for compound fertilizer production comprises a base, a smashing tank, a bearing, a primary screening tank, a secondary screening tank, a second drive motor and a special-shaped gear, wherein the smashing tank is fixedly installed on the base through screws; two sets of mainsmashing rollers are installed in a smashing cavity in a bilateral symmetry mode; auxiliary smashing rollers are further rotationally installed in the smashing cavity; a scattering disc is further fixedly connected to the upper end of an output shaft of a first drive motor; the second drive motor is further fixedly installed on the outer wall of the right side of the smashing tank; and the special-shaped gear is further installed on an output shaft of the second drive motor. According to the smashing and screening device for compound fertilizer production, the structure is novel, and fertilizer particles are more uniform in the smashing process; and through arrangement of the scattering disc, smashed fertilizer is evenly tossed out and then falls into the primary screening tank, so that the fertilizer on the primary screening tank is evenly distributed and prevented from being accumulated on a screen of the primary screening tank.

Description

technical field

[0001] The invention relates to the field of chemical fertilizers, in particular to a crushing and screening device for compound fertilizer production. Background technique

[0002] At present, compound fertilizers provide one or more essential nutrients for plants, improve soil properties, enhance

[0003] A class of substances with high levels of soil fertility. One of the material bases of agricultural production, different ingredients need to be mixed when configuring compound fertilizers

[0004] The ratio of the fertilizer is mixed, and the crushed fertilizer is easier to fuse, but the crushing process cannot completely crush the fertilizer.

[0005] The size of the crushed particles is different, and the efficiency of screening after crushing is low and the fertilizer is piled up inside the screening box after crushing, resulting in a slow screening speed. Contents of the invention

[0006] The object of the present invention is to provide a crush...

Embodiment Construction

[0022] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0023] see Figure 1-3 , a crushing and screening device for compound fertilizer production, comprising a base 1, a crushing box 2, a bearing 10, a primary screening box 15, a secondary screening box 16, a second drive motor 19, and a special-shaped gear 20, and the base 1 is fixed by screws A crushing box 2 is installed, and a feeding port 3 is opened at the center of the upper side of the crushing box 2, and the feeding port 3 is connected to an external feeding device. The inside of the crushing box 2 is provided with a crushing chamber 4, and the crushing chamber 4 communicates with the feeding port 3. Two groups of main crushing rollers 5 are installed left and right symmetrically in the inside of the crushing chamber 4, and the distance between the two groups of main crushing rollers 5 is 4-6mm. The inside of the crushing chamber 4 is also ro...
