1. How to make organic fertilizer from urban sludge?
At present, with the development of organic fertilizers made by organic fertilizer pellet making machine encouraged and rewarded by many countries, urban sludge has also become a treasure.
(1) After fermenting biogas from sewage treatment plants or manures such as cow dung, the biogas residue and sludge are subjected to pressure filtration and then enter the batching part of the complete set of sludge composting equipment of the organic fertilizer pellet making machine factory into the silo;
(2) The raw material ingredients of sludge include crushed straw and sawdust powder, and the deodorizing powder is added to the batching part of the complete set of sludge composting equipment of the organic fertilizer pellet making machine factory according to different proportions into the silo;
(3) The prepared material enters the main belt and enters the double-shaft forced mixer for continuous stirring, and the mixing is uniform;
(4) The prepared materials are transported to the drum fermentation machine through the belt conveyor for pre-fermentation;
(5) The fermented materials are transported to the dump truck through the belt conveyor and transported to the fermentation tank for secondary fermentation.
(6) The secondary fermentation adopts the sludge fermentation turning and throwing machine. This organic fertilizer equipment factory turning and throwing machine solves the situation that the aeration holes are basically blocked by the aerobic fermentation and aeration method of the sludge, and the sludge fermentation is turned over. The throwing machine can supply oxygen to the sludge at the same time during the turning and throwing process.
The sludge organic fertilizer pellet making machine and organic fertilizer production line refers to a complete set of equipment that uses chicken manure as the main raw material to produce organic fertilizers. Some customers with less investment choose fermentation equipment, crushing equipment, screening equipment and packaging equipment to form a organic fertilizer pellet making machine production line of powdered organic fertilizer.
After several years of research and the introduction of foreign microbial fermentation technology, Richi Machinery has successfully completed the process and complete sets of organic fertilizer pellet making machine for the production of sludge treatment organic fertilizers in combination with soil, crops, climate and other conditions.
After the sludge treated by our company’s technology is made into compound organic fertilizer, the fertilizer particles are neat, the nutrients required by plants in organic and inorganic are sufficient, and various plants are easy to absorb, which can increase crop yield by more than 10%, and can play a role in Loosening the soil and improving the soil quality will play a major role in the fertilizer industry.
2. Working principle of organic fertilizer pellet making machine
Using the mechanical stirring force of high-speed rotation and the resulting aerodynamic force, the fine powder material can be continuously mixed, granulated, spheroidized and densified in the organic fertilizer pellet making machine, so as to achieve the purpose of granulation.
The particle shape is spherical, the sphericity is greater than or equal to 0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is greater than or equal to 90%. The size of the particle diameter can be properly adjusted by the material mixing amount and the spindle speed.
Generally, the lower the mixing amount, the higher the speed. The higher, the smaller the particles, and vice versa. Scope of application: This organic fertilizer pellet making machine is especially suitable for the granulation of light and fine powder materials.
- The finer the basic particles of the fine powder material, the higher the sphericity of the particles and the better the quality of the ball. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc.
- The organic fertilizer pellet making machine is specially used for granulating organic fermented fertilizers with organic fertilizer raw materials such as livestock and poultry manure, composting fertilizers, green manures, sea fertilizers, cake fertilizers, peat, soil and miscellaneous fertilizers, three wastes, microorganisms, etc. , the particles are spherulites.
- The qualified granulation rate of this organic fertilizer pellet mill machine is as high as 80-90%, and it is suitable for a variety of different formulas. The compressive strength of organic fertilizer is higher than that of discs and drums, the rate of large balls is lower than 15%, and the uniformity of particle size can be passed according to user requirements.
- The organic fertilizer making machine has stepless speed regulation function adjustment.
- This organic fertilizer pellet machine is most suitable for direct granulation of organic fertilizer after fermentation, which saves the drying process and greatly reduces the manufacturing cost. Complete sets of new organic fertilizer equipment.
The products produced by the bio-organic fertilizer pellet making machine are made of fresh chicken and pig manure, without any chemical ingredients. However, chickens and pigs have poor digestion ability and can only consume 25% of the nutrients, while the other 75% of the nutrients in the feed are excrement discharge extrusion organic fertilizer pellet making machine, double roll granulator, trommel screen, high moisture material dryer, BB fertilizer blender, double roll fertilizer pelletizer, fermentation turner, , drum fertilizer pelletizer, multifunctional organic fertilizer (biological) spherical organic fertilizer pellet making machine.
