Problems solved by technology

During the crushing process, it is difficult to separate the crushed feed from the coarse feed. Even the crushed feed will be re-entered into the grinder for re-grinding, so a lot of dust will be generated. The above-mentioned solution is only a sealed environment for crushing. When it is necessary to install When it is bagged or discharged, a large amount of dust generated by crushing will still be raised and dispersed in the air

Embodiment 1

[0019] Embodiment 1 is basically as attached figure 1 Shown: a working method of a crushing device for feed production, the crushing device includes a grinder 10, a pneumatic discharge pipe 20, a pneumatic return pipe 30, a separation tower 40 and a settling tank 50, and the inside of the separation tower 40 is from top to bottom The first screen cloth 60 and the second screen cloth 70 arranged obliquely are provided, and the inclination angles of both are 8° in this embodiment, and the screen holes of the first screen cloth 60 are larger than the screen holes of the second screen cloth 70; One end of the pneumatic discharge pipe 20 communicates with the discharge port of the pulverizer 10, the other end communicates with the separation tower 40, and is located above the first screen 60, and one end of the pneumatic discharge pipe 20 communicates with the feed port of the pulverizer 10, The other end is communicated with in the separation tower 40, and is positioned at the fir...

Embodiment 2

[0025] The difference from Embodiment 1 is that: the upper surface of the first screen 60 is provided with several conical protrusions 61 .

[0026] Step 2 also includes the following step. The feed with large particles rolls on the upper surface of the first screen 60 and is crushed by the conical protrusions 61 . The feed discharged from the pneumatic discharge pipe 20 has a certain speed, and the pneumatic discharge pipe 20 will make the feed on the first screen 60 continue to roll, especially for feed with a larger particle size, the feed on the upper surface of the first screen 60 will In the process of rolling, it will be crushed again, so that the amount of material returned by the pneumatic return pipe 30 can be reduced, and the crushing effect can be improved.

Abstract

The invention discloses a working method of a crushing device for feed production. The working method comprises the following working steps: (1) feeds to be crushed are added in a crusher for smashing; (2) the smashed feeds are fed into a separation tower via a pneumatic discharge pipe; the feeds are screened for the first time on a first screen; rough feeds screened out from the first screen are feed into the crusher for smashing again via the pneumatic discharge pipe; (3) the feeds with qualified particle sizes and powder-shaped feeds continuously drop down to a second screen; and the feeds with qualified particle sizes are screened down, and are discharged from a discharge port in a low end of the second screen; and (4) the powder-shaped feeds continuously drop down and enter a settling tank via a pipe; and the powder-shaped feeds are totally settled through water mist sprayed out by a sprayer in the settling tank. The method of the crushing device generates a lower dust quantity, and cannot raise a lot of dust during bagging or discharging.

Description

technical field [0001] The invention belongs to the field of separation or sorting of materials matched with crushing or crushing, and in particular relates to a working method of a crushing device for feed production. Background technique [0002] Feed grinder is mainly used to crush various feeds and roughages. The purpose of feed crushing is to increase the surface area of ​​feed and adjust the particle size. Increasing the surface area improves palatability, and it is easy to contact with digestive juice in the digestion side, which is conducive to improving digestibility. , better absorption of feed nutrients. On the one hand, adjusting the particle size reduces the energy consumed by livestock and poultry chewing, and on the other hand, it is more convenient for transportation, storage, mixing and granulation, and the efficiency and quality are better. [0003] At present, the common feed grinder will generate a lot of dust during the crushing process, and the dust wi...
