A chemical fertilizer crushing and drying device

Abstract

The invention discloses a chemical fertilizer crushing and drying device, which comprises a casing, wherein a support frame is fixedly arranged in the middle part of the upper end of the casing; the top end of the support frame is provided with a crushing motor; an output shaft of the crushing motor is connected with a crushing shaft; the upper end of the crushing shaft is fixedly provided with a plurality of first crushing bulges; second crushing bulges are arranged at the two sides of the first crushing bulges; a first baffle plate is welded at the middle part of the crushing shaft; a plurality of third crushing bulges are fixed on the first baffle plate; a second baffle plate is arranged on the bottom end of the crushing shaft; the upper end of the second baffle plate is fixedly provided with a plurality of fourth crushing bulges; a support plate is fixedly connected with the bottom end of the casing; a bottom plate is arranged at the lower end of the support plate; a guide rod is arranged between the bottom plate and the support plate; a vibration reduction spring is arranged on the guide rod in a sleeving way. The chemical fertilizer crushing and drying device has the advantages that the structure is simple; the design is reasonable; through the crushing for many times, the fertilizer reaches the crushing requirements; meanwhile, the fertilizer can be dried; the production cost is reduced; the vibration reduction effect of the device is good; the service life is prolonged.

Description

technical field [0001] The invention relates to the field of chemical fertilizer processing, in particular to a chemical fertilizer crushing and drying device. Background technique [0002] Chemical fertilizers refer to processed fertilizers, also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. They have the following common characteristics, simple ingredients, high nutrient content, fast fertilizer efficiency, and strong fertilizer , There are many types of chemical fertilizers, and their properties and application methods are quite different.

Problems solved by technology

[0003] During the long-term storage of chemical fertilizers, under the influence of air humidity, it is easy to absorb moisture and cause compaction. The agglomeration of chemical fertilizers will have a serious impact on the accuracy of measurement. When crushing chemical fertilizers, a crushing device is required. Modern crushers generally only perform one-time crushing, and the crushing effect is not very good. At the same time, modern crushers generally do not have a drying device, and additional drying is required for drying. dry machine, which will cause an increase in production costs, which is not conducive to the development of enterprises
