Compound fertilizer production equipment and method for improving particle surface roundness

Abstract

The invention discloses compound fertilizer production equipment and method for improving particle surface roundness, and belongs to the technical field of compound fertilizer production and processing. The compound fertilizer production equipment comprises a bottom plate, supporting columns are fixedly connected to the left side and the right side of the upper surface of the bottom plate, and supporting wheels are clamped to one sides of the supporting columns; the two supporting wheels are arranged on the left side and the right side of the sorting assembly correspondingly. According to the equipment, part of materials which do not penetrate through the screening drum can continuously roll in the screening drum, meanwhile, the multiple material guiding plates rotate, the materials rise to the top of the screening drum under the action of centrifugal force and then can fall onto the material guiding plates under the action of gravity, the materials continuously roll on the arc-shaped material guiding plates, and the material guiding plates can further separate large-particle materials; the materials are continuously rolled into balls and penetrate through the through holes in the screen drum, so that the compound fertilizer particles are prevented from vertically falling to be in contact with the screen drum, deformation of the particles caused by overlarge impact is prevented, the generated particles are uniform in size, the surface roundness of the particles is further improved, and the production quality of the compound fertilizer is improved.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production and processing, in particular to a compound fertilizer production equipment and method for improving the roundness of particle surfaces. Background technique [0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It is very important for balanced fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. However, it also has some disadvantages. For example, its nutrient ratio is always fixed, and the types, quantities and ratios of nutrient elements required by different soils and different crops are varied. Therefore, it is best to test the soil before use to understand The texture and nutritional status of the soil in the field. In addition, attention should also be pa...

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a compound fertilizer production equipment and method that improves the roundness of the particle surface, which solves the problem that the compound fertilizer with fast particle formation will be affected by centrifugal force when it moves to the top of the drum. Gravity affects direct falling and vertical contact with the compound fertilizer particles at the bottom, which will easily cause the compound fertilizer particles to receive too much impact and be forced into balls, which will easily cause the particles to be uneven in size, resulting in a large gap in the size of the particles formed in the drum.
