Ordinary calcium superphosphate feeding, screening, crushing system

Abstract

A common calcium superphosphate feeding, screening and crushing system relates to the field of calcium superphosphate production. Including feeding system, screening system and crushing system. The material in the silo is dropped to the feeding system by gravity, and the feeding system feeds the material evenly to the screening system, and after reciprocating screening, the finished product is transported to the automatic packaging system. The remaining large particle materials enter the crushing system for crushing and re-enter the silo. The present invention feeds completely without manual labor, and implements automatic feeding, which effectively reduces labor intensity and production cost; the finished product is loose after screening, and there is no wet lump scarring or hardening phenomenon; a small amount of the product after feeding and screening is used by the blade Cutting of large pieces can avoid large-area contact and cause the material to become muddy; economical and practical, high product quality, convenient operation, labor-saving, time-saving, labor-saving, and smooth system; not only suitable for feeding and screening of ordinary calcium superphosphate It can be divided and broken, and it is also very suitable for similar products such as heavy calcium and rich calcium.

Description

technical field [0001] The invention relates to the technical field of calcium superphosphate production, in particular to a general calcium superphosphate feeding, screening and crushing system. Background technique [0002] At present, due to the part of the matured superphosphate needs to be broken, and the calcium superphosphate contains 15% water, 3-4% free acid, and magnesium sulfate containing a little water. During the vibration process, crystalline water seeps out, causing the wet lumps of fertilizers to form scars and agglomerates, affecting the physical properties of the product and the appearance quality of the product. For the crushing of superphosphate before packaging, manual feeding and rolling extrusion are generally used, which has the following defects: [0003] 1. Operators have high labor intensity and high production costs. [0004] 2. The wet block of the material part is scabbed by the rolling extrusion, and the fertilizer is not loose and hardened,...

AI Technical Summary

Problems solved by technology

[0003] 1. Operators have high labor intensity and high production costs

[0004] 2. The wet block of the material is partially scabbed by the rolling extrusion, and the fertilizer is not loose and hardened, which affects the appearance quality of the product

[0005] 3. The whole system is not smooth, there are many fault points, and the operation is difficult
