The difference between rotary drum granulator and counter roll extrusion granulator

图片
  Both   rotary drum granulators   and roller extrusion granulators have their own advantages in fertilizer production, and they have significant differences in multiple dimensions. In terms of working principle, the  rotary drum granulator  uses a rotating drum to lift up the material internally. Under the action of centrifugal force, friction force, and gravity, the material circulates and the binder is sprayed to form the particles. The counter roll extrusion granulator uses a pair of rotating rollers to squeeze the material into the concave mold on the surface of the rollers, without the need for adhesive (which can be added in some cases). In terms of particle characteristics, the shape of the particles produced by the rotary drum granulator is relatively regular, mostly approximately spherical or elliptical, and the surface of the particles is relatively smooth. Due to the sufficient rolling of the material inside the drum, the internal structure of the pa...

Cake and meal materials are a type of nutrient rich organic fertilizer granulation raw material

图片
  Cake and meal materials are a type of nutrient rich organic fertilizer granulation raw material that plays an important role in improving the quality of organic fertilizers. Bean cake is one of the most common raw materials for cake and meal. The soybean cake left after pressing and extracting oil contains a large amount of protein, amino acids, as well as nutrients such as nitrogen, phosphorus, and potassium. These rich nutrients make soybean cake a high-quality raw material for organic fertilizers. After fermentation treatment, the high molecular weight organic matter in soybean cake is decomposed into small molecules, which are more easily absorbed and utilized by crops. Using an  organic fertilizer granulator  to turn fermented soybean cake into granular fertilizer can accurately control the nutrient content and release rate of the fertilizer, providing comprehensive and lasting nutritional support for crop growth. Rapeseed cake also has high nutritional value. It c...

Equipment characteristics of small-scale livestock and poultry manure organic fertilizer production line

图片
  Livestock and poultry manure includes chicken manure, pig manure, cow manure, sheep manure, horse manure, duck manure, rabbit manure, pigeon manure and other livestock and poultry manure, as well as straw decomposed organic fertilizer. These livestock and poultry manure and straw are pure organic fertilizers when they are not processed or fermented in any way. Agricultural manure and livestock manure are not decomposed or fermented, and are directly used on crops, which can cause soil hypoxia, disease and pest breeding, and slow fertilizer efficiency The problems of fermentation, seedling burning, and harmful gas damage seriously affect crop growth and harvest. Chicken manure ferments organic fertilizer, and the main substance in chicken manure is organic matter. Applying chicken manure increases the organic matter content in the soil, which can improve the physical, chemical, and biological properties of the soil, mature the soil, and enhance soil fertility. Therefore, fermented...
