Firstly,the siudge deposited by municipal sewage:
Although contain the organic matter of certain amount and nitorgen phosphor potassium composition,this kind of raw material need not spend money,treatment cost is very low,but heavy metal and escherichia coil exceed bid badly,easy cause dead root,dead tree phenomenon,fruit persoon eats hind easy cause malignant canceration.
Secondly,Sluge deposited by industrial wastewater:
Although this kind of sludge also contains a large number of elements and organic matter,heavy metals are also seriously exceeding the standard,which can cause root rot and dead trees and seriously pollute the soil.
Thirdly,Paper mill waste:
This fertilizer is mainly composed of lignin is very difficult to absorb a kind of organic matter,and in the process of papermaking to add a lot of chemical raw materials remain in the waste material,it is a great damage to the soil,the root of the great impact.
It belongs to the apparent organic matter and cannot become the carbon source of soil microorganisms.The effective component in weathered coal is humic acid,but it is invalid orgasnic nutrient without deep producessing.
High quality organic fertilizer main ingerdients:animals and plant remains,brand powder,bone powder,corn starch,amino acid,protease.The food materials are all putrid and ripe,and it is safer for crops to apply them into the soil,which is more conductive to the transformation of organic matter and nutrients.
Then,if we want to produce the high quality organic fertilizer ,for different raw material we need to use different organic fertilize machine.For example,if we want to produce the organic fertilizer granulator,we can choose the machine of
disc granulator and ring die granulator.
The complete fertilizer granulator production line :
Taking the rotary drum granulator as the sample,if use the rotary drum granulator to produce the organic fertilizer,it mainly including these machines:
1,Batching system series
The multiple silos single weigh static batching machine is mainly suitable for mixing,batching and feeding of 3-8 kinds of materials.The single silo single automatic batching system is a kind of automatic proportioning device which cn be used with organic fertilizer equipment,BB fertilizer equipment and compound fertilizer equipment.
2,Fertilizer crusher machine series:
The crusher machines inclunding many kinds ,like the chain crusher,half wet material crusher,cage crusher and single axis urea crusher.They can be used in different raw material.
Chain crusher is applied to the shattering of the block in the production of organic fertilizer.Also,it is widely used in chemical industry,building materials,mining and other industries.
3,Rotary drum granulator
The rotary drum granulator is suitable for large scale production of cold,hot granulation and high ,medium and low concentration compound fertilizers.
We will provide the suitable burner fire stove according to the demends of clients.
5,Drum fertilizer dryer
Rotary drum dryer is mainly used to produce compound fertilizer and dry a certain temperature and granularity of fertilizer.On the other hand ,it also can be used for drying other materials.
6,Drum fertilizer cooler
Rotary drum cooler fertilizer used for the production of compound fertilizer,cool fertilizer with certain temperture and particle size.Use dryer together can greatly improve the cooling rate ,reduce labor intensity and improve the quality ,further remove moisture,reduce the grain temperature of fertilizer.
7,Drum screener machine
rotary drum screening machine is common equipment in compound fertilizer production,mainly used for separating the returned materials and finished product,also realize the classification of the end products,and even classify the end products.
The rotary coating machine can be lined with polypropylene or acid resistant stainless steel in the main engine.The coating agent is adhered to the surface of the granule with a powder coating machine or a liquid melting pot.
Feeding speed adjustable:powder material feeding through screw feeder,could automatic control fast feeding and slow feeding speed can be set any time.
