Description
Technical field
The present invention relates to a kind of organic fertilizer processing unit (plant), especially a kind of grinding batch mixing dress for the tea grounds organic fertilizer that gives up
It sets.
Background technology
Be mainly derived from plant and（Or）Animal imposes on soil to provide the carbon containing object that plant nutrient is its major function
Material.Through biological substance, animals and plants waste, plant residue processing, poisonous and harmful substance therein is eliminated, rich in a large amount of
Benefit materials, including：A variety of organic acids, peptides and the abundant nutrient including nitrogen, phosphorus, potassium.It can not only be agriculture
Crop provides full nutrition, and fertilizer efficiency is long, can increase and update the soil organism, promotes microbial reproduction, improves soil
Physicochemical property and bioactivity are the Main Nutrients of pollution-free food production.
It often generates largely useless tea grounds, tea grounds in Tea planting process to be difficult to directly handle as waste, directly
It abandons then easy moldy metamorphism pollution environment and causes disease；Useless tea grounds the adding typically as organic fertilizer in current production process
Charging, but useless tea grounds is not easy to be difficult to degenerate completely during prepared by organic fertilizer, and organic nutrient fails fully to be discharged, system
At organic fertilizer quality matte, fertility is insufficient.It is typically required waste residue precrushing again when preparing organic fertilizer using the tea grounds that gives up
Organic fertilizer corruption is carried out to prepare, existing crushing plant typically uses crusher or wire kneading machine, but due to useless tea grounds usually compared with
It is small, and soft texture, it is difficult to be broken machine or wire kneading machine is broken into uniform little particle, be prepared with such fannings slag organic
There are still the uneven problem with fertility deficiency of quality, the qualities of organic fertilizer to be difficult to be improved for fertilizer.
