Ammonium Sulfate Mobile Roller Compress Extrusion Granulator Production Line

Introduction of NPK Fertilizer Production Line

NPK Compound fertilizer production line is widely applied to produce compound fertilizer and the capacity ranges from 5000-200,000 tons/year. It can granulate NPK, NP, ANP, DAP, MAP, CAN, SSP and other materials into compound fertilizer particles in one processing line.

1) The roll extrusion granulator machine a newly developed granulating machine in fertilizer industry.

2) It uses squeezing principle to form fertilizer particles with diameters of 3.5-10mm in one time.

3) It has higher granulating ratio of over 85%.

4) Cattle Feed Pellet Machine is the most popular granulating methods in no-drying (2%-5% moisture content) fertilizer process at room temperature.

5) Less cost and quick granulating,thus it can bring fertilizer investment a good economic returns.

Raw Material For NPK Compound Fertilizer Making Production Line

Compound fertilizer is the fertilizer containing two or all three of the three basic plant nutrients—Nitrogen, Phosphorus, and Potassium, as well as microelements, such as B, Mn, Cu, Zn, and Mo. The raw material can be powder or bulk, mostly are as below:

Working Process Of NPK Compound Fertilizer Making Production Line

NPK Compound fertilizer production line usually includes 7 processes, batching, grinding, mixing, granulating, screening, coating and packaging. Batching, mixing, granulating and screening processes are necessary. Other processes are optional based on different capacity.

It adopts the design solution of extrusion sliding model,the raw materials pass through double roller,after that,enter into scattering room, come out as granulation, a sieving was mounted at the bottom of the machine, which is customized according to client’s requirement, last, sieve out the granules which is qualified, the rest of materials return to mixer and be re-granulated.

Main Equipments Of NPK Compound Fertilizer Making Production Line

1. the dynamic or static batching machine

2. crushing machine

3. mixing machine

4. granulating machine

5. screen machine

6. packing machine

The instruction of the roller extrusion granulator

1. No drying technology, normal temperature granulating, once forming.

2. Low investment, quick profit, good economic returns, etc.

3.Combine granulating,forming,screening into one machine,making beautiful appearance

granules, easy operation and low energy consumption, etc.

4. Especially, DZJ-5. not only has the above features, but also upgrades its rack.The bearing

frame body is made of high quality and anticorrosive cast materials, so that it become more

stable and extends the roller’s service life.

Features of NPK Fertilizer Production Line

A. small investment,quick profit,good economic returns

B. saving energy,reducing consumption,no "three wastes" discharge

C. stable operation,reliable operation,easy maintenance,wide raw material adaptability

D. granulating,molding,screening into one machine,make finished product with good appearance,easy to operate

E. main components such as roller body adopts new type metal to refine with anticorrosive, abrasion resistance, shock resistance characteristics

F. bearing bracket select excellent anticorrosion casting parts for whole body, greatly improve service life of rolling bearing and main shaft

G. transmission part adopts twoinput transfer mode, not only improve input power ratio, but also ensure the lubrication and sealing performance of transmission gear

H. compact structure, good stability, good sealing, low noise, easy operation and maintenance

Mainly including compound fertilizer production equipment, organic fertilizer production line equipment, double-roll press granulat
