Analysis of Granulators Suitable for NPK Fertilizer Production Lines

NPK fertilizer, as a compound fertilizer, contains three key nutrients: nitrogen, phosphorus, and potassium, and is widely used in agricultural production. Its production line places high demands on granulators, requiring them to adapt to varying raw material ratios and ensure granule uniformity and strength. Currently, the following types of mainstream equipment are suitable.

The rotary drum granulator is a classic choice for NPK fertilizer production lines. Its rotating drum tumbles and agglomerates the material within the drum, making it suitable for a variety of raw material combinations. This equipment boasts a large processing capacity, with a single unit capable of processing 10 to 50 tons of material per hour. Its rounded, high-strength granules meet the needs of large-scale production. However, it has strict requirements for raw material moisture control, typically maintaining a humidity level of 25% to 35%, making it more suitable for medium- and large-scale fertilizer production enterprises.

The double roller press granulator is suitable for NPK fertilizer production with lower raw material moisture. A roller press granulator uses two counter-rotating rollers to compress the material into flakes before crushing and granulating it. It eliminates the need for drying, consumes relatively little energy, and can achieve a pellet formation rate exceeding 95%. It is suitable for small and medium-sized production lines or enterprises with strict energy control requirements.

Disc granulators are commonly used in small NPK fertilizer production lines. They utilize the rotation and tilt of the discs to aggregate and granulate the material under the influence of centrifugal force and gravity. The equipment occupies a small footprint, offers low investment costs, and is easy to operate and maintain. However, its processing capacity is relatively small, typically ranging from 1 to 8 tons per hour. It is more suitable for small-batch, multi-variety NPK fertilizer production, such as for family farms processing fertilizer for their own use or small fertilizer workshops.

Different granulators have their own advantages and disadvantages. Manufacturers should select the appropriate granulation equipment based on their scale, raw material characteristics, and product requirements to ensure efficient operation and product quality of their NPK fertilizer production lines.

Equipment composition and cost of sheep manure organic fertilizer production line

Image
  At present,the  organic fertilizer production line  is more popular in the market.At present,we have roughly understood that the role of organic fertilizer production line is to treat the livestock manure to produce organic fertilizer,which not only deals with the livestock manure pollution,but also achieves the purpose of resource recycling.At the same time,the design and production of mechaincal equipment also promote the application of organic fertilizer production line,so what is the process flow in the organic fertilizer production line designed by using organic fertilizer equipment? The raw materials for the production of organic fertilizer include chicken manure,sheep manure,cattle manure and other animal manure.The technological process of sheep manure organic fertilizer production line is mainly as follows:add fermentation bacteria to organic waste,add some auxiliary raw materials,mix them and put them into fermentation tank for 7-8 days,and then they can be di...

Organic fertilizer production project and workshop configuration

Image
The traditional livestock and poultry breeding mode has a great impact on the surrounding ecological environment. How to solve this problem? Carry out ecological breeding mode and take a new way of green ecological and environmental protection. Relying on the organic fertilizer project, through organic fertilizer production equipment , the high-efficiency circular ecological breeding industry chain is continuously extended. Workshop configuration of organic fertilizer production project For example, if the annual output of 5000 tons is calculated as 10 months per year, the monthly production capacity is 500 tons. Each ton of fertilizer needs about 2 square meters of raw materials, then 1000 square meters are needed for a month. If the fermentation time of organic fertilizer is calculated as 15 days, the fermentation workshop needs at least 500 cubic meters of organic fertilizer raw material storage space. Calculated according to the turning height of the ordinary trough compost tu...

Organic fertilizer manufacturing process and machine composition

Image
A series of processing and organic fertilizer manufacturing machine can realize the resource utilization of animal manure and straw waste such as chicken manure, sheep manure, cow manure, etc. What are the manufacturing processes of organic fertilizer? What equipment is needed in this production process? After the compost fermentation is completed, the compost is crushed into powder in the organic fertilizer crusher. The powder is mixed into the organic fertilizer mixer to add auxiliary materials for mixing. After mixing evenly, the compost is put into the granulator to make particles. The particles are sent into the dryer to reduce the moisture content of the particles to 10-20%. After cooling, the compost is sent to the cooler for screening, and the unqualified products are screened out for recycling The belt conveyor enters into the pulverizer again to crush and screen out the finished products, which can be packaged directly. Composition of organic fertilizer manufacturing e...
