What are the problems that need attention in the production process of organic fertilizers! First of all, the location of the organic fertilizer plant is very critical, it is best to be closer to the raw materials, the raw materials of organic fertilizer are generally locally sourced, if the supply of raw materials is guaranteed by long-term transportation, the cost will increase a lot.
After the raw materials enter the cattle manure fermentation machine to start fermentation, they should observe the moisture and temperature of the materials during the fermentation period at any time, control the changes in raw materials in time, make timely treatment, and use the aerobic composting machine to turn the pile to ensure the uniform and thorough fermentation of the materials. Fermentation bacteria can be added during fermentation to speed up the speed of fermentation, but it is not recommended to add other biological bacteria during this period, because the temperature of the material is very high during fermentation, and many beneficial bacteria cannot withstand the high temperature.
After the material is fermented by the fertilizer conveyor to the forklift silo for use, this silo is generally with speed regulation function, can be a good control of the feeding speed of the follow-up equipment, from the silo out of the mixer, this time can add a certain excipient to the raw materials, mixer We generally recommend designing two, one stirring and one discharging. Material mixed evenly into the crushing, crushing machine and the general crusher is not the same, because we need materials to maintain a certain amount of moisture, so the crusher to use semi-wet material crusher, this crusher for the material moisture in 20%-50%, can be fully competent for our organic fertilizer raw materials crushing.
Granulation is the whole production line most affect the final molding effect, the choice of organic fertiliser granulator is crucial, according to the different raw materials, the model we want to use is not the same, for example, we want to use cow feces as fertilizer, appropriately add some other organic substances (straw, sawdust, etc.), then our suggestion is the organic fertilizer tooth pelletizer, this model is the use of churning teeth and cylinder wall between the matching to make the material forced into granulation, so to some fiber coarser livestock and poultry manure effect is better. If our raw material is organic plus inorganic fertilizer, then we need to use organic fertilizer combination granulator, which can make the perfect combination of manufacturing granular fertilizer.
We all know that organic fertilizer needs to add a certain amount of biological bacteria, but high temperature will kill and reduce the survival of biological bacteria, so the control of temperature is crucial, if the yield is large, we generally recommend increasing drum dryer machine and reducing the temperature to ensure the survival of biological bacteria. It is also possible to consider adding a coating cylinder after drying to wrap the biobacterium directly on the surface of the material.
