The difference between horizontal mixer and vertical mixer

 Regardless of the horizontal mixer or the vertical mixer, the mixing uniformity of the materials is an important indicator for evaluating the performance of a fertilizer mixer machine, and it is also an important factor affecting the entire fertilizer manufacturing process and product quality. For the fertilizer production industry, mixing evenly degree has a great influence on the size range and size uniformity of the particles processed in the subsequent process.

In the case of a horizontal mixer, the internal blades move relative to each other to form a shear plane, which shears and kneads the material. With the constant rotation of the auger, the material will form a vertical drop when it accumulates to a certain height, free fall by the material's own weight to overcome the friction and cohesion, or it will slide down along the inner wall of the feed mixer to form diffusion. The dropped material is mixed with the material at the bottom of the silo, and the mixture is tumbling in the axial direction to form a cross-mixing motion, which realizes convection and extrusion of the mixture in the silo, thereby making the difference in particle size, mass and water content larger. Different materials slide and infiltrate into each other in the silo, and the material is multi-cycle stirring motion in the three-dimensional space in the silo, and is continuously and uniformly mixed by shearing, smashing, spreading and stirring to effectively prevent the mixture. The material produces agglomeration, which makes the material fluffier and guarantees the quality of the post-granulation.

The vertical mixer has a vertical cycloidal reducer. The mixing chamber has a low cylindrical structure, and the material is laid into a thin layer, so the required power is not very large, and it is more suitable for the stirring of the fertilizer raw materials. Because the fertilizer raw material and its easy moisture absorption, and has a certain viscosity, it is easy to stick to the wall of the disk during production, forming a dense material bonding layer, resulting in a large internal friction of the machine, so that the blending mixer is subjected to excessive load, In order to avoid the impact of motor overload on the production, the feeding port is equipped with a movable protective net to prevent too much material from entering the mixer on the one hand, and as a safety precaution to prevent accidents during operation. The inside of the silo can also be lined with plastic plates to reduce the material adhesion and friction, and it is not easy to cause the plate body to rust and prolong the service life of the whole machine.

Horizontal mixers and vertical mixers have different adaptability to various materials due to different design methods. In the family of fertilizer production equipment, horizontal mixers are used in organic fertilizer production lines, while vertical mixers are used in NPK fertilizer production, but as a user, what kind of mixer is used, you also need to choose according to your own material type.
