Rotary Drum Compound Fertilizer Production Line Working Flow

1. Material Proportioning: The first process of the production line is proportioning process, where various raw materials are proportioned according to the formula. We adopt six bin batching machine here, which can complete proportioning automatically with high accuracy and high efficiency, ensuring the quality of finished products. After batching process, the materials are sent to the mixer by the belt conveyor.
2. Material Mixing: We use two pan mixers in this line for the mixing of raw materials. The mixers can fully mix the materials so that to increase the utilization rate of granular fertilizer. The inner side of the disc is made of polypropylene plate or stainless steel, which makes raw materials not easily sticky, and abrasion resistance. After mixing, the materials will be discharged through the outlet at the bottom, and sent to the fertilizer granulator by the belt conveyor.
3. Fertilizer Granulation: The evenly mixed materials enter into the rotary drum granulator from the feed end. With the constant rotating of the cylinder, the materials form a rolling bed. Under the extrusion force produced, the materials agglomerate into small particles, which become the core, attaching the powder around to form the qualified spherical granules, which finally discharge through the discharge end. Our rotary granulator has high fertilizer granulation rate, which can reach 70%. Lining with pvc plastic plate or stainless steel plate, the material is not easy to stick to the cylinder.
4. Fertilizer Drying: By the belt conveyor, the wet fertilizer enters into the rotary dryer from the feed hopper at the higher end. With the rotation of the cylinder, the wet fertilizer co-current contacts with the hot air suctioned from the hot blast stove and exchange heat, thus the moisture is evaporated. The dried granules discharge through the outlet at the lower end. The tail gas enters into the dust settling chamber.
5. Fertilizer Cooling: By the belt conveyor, the hot fertilizer from the dryer is sent into the rotary cooler through the feed hopper at the higher end. With the rotation of the cylinder, the materials counter-current contact with the suction cool air and exchange heat, thus the temperature is reduced. The cooled materials flow out from the lower end. The tail gas enters into the dust settling chamber.
6. First Screening: Cooled fertilizer granules enter into the rotary screener through the feed hopper at the higher end. With the rotation of the cylinder, unshaped granules passing through the screen aperture are discharged through the outlet at the bottom and sent back to the mixer, while shaped granules flow forward and discharge through the outlet at the lower end of the machine. The rotary screen adopts combined screen, which is easy for maintenance and replacement.
7. Second Screening: By the belt conveyor, shaped granules from previous process are sent to the second rotary screen, where qualified granules are discharged through the outlet at the bottom and sent to the coating machine, while unqualified particles are crushed and sent back to the mixer for re-granulation. The vertical chain crusher adopts wear-resistant chain and rubber lining, having long service life and the materials are not easy to stick on the inner wall.
8. Fertilizer Coating: The conveyor belt sends the qualified granules from the second screen into the rotary coating machine from the higher end. With the rotation of the cylinder, powder or liquid are evenly coated on the surface of granules, which prevent caking, meanwhile increase the brightness and roundness of the granular. The machine is lined with polypropylene plate or stainless steel plate. After coating, the fertilizer granules discharge from the lower end of the cylinder.
9. Fertilizer Packaging: By the belt conveyor, the coated fertilizer are sent to the finished products warehouse to be packed by the automatic packing machine. We have designed two finished products warehouses and packing machines for this fertilizer production line. The packing machine can complete feeding, weighing, conveying and sealing process automatically. Packed fertilizer can be stored for sale.

Groove Type Compost Turner

This organic fertilizer compost turner, which includes groove type compost turner and groove type hydraulic compost turner, is the most widely-used aerobic fermentation machine and compost turning equipment. It includes walking fermentation groove, walking track, power-pick device and other parts. The working portion of the compost turner machine adopts advanced roller drive. There are adjustable type and non-adjustable type for choice. The groove type compost windrow turner is widely used for dealing with animal manure, household garbage, sludge, crop stalks and other organic wastes, and also can be used in feed fermentation.

Features of Fertilizer Compost Windrow Turner:

1. The operation span of the Lane Turner is four to twelve meters and the fermentation period is about fifteen days. The length of the fermentation groove depends on the particular condition. The feeding and discharging of the material can be done at the same time. The compost turner can raise the augers and fast move to another working area after it finishes one section.
2. The innovation point of this compost making machine is to take full advantage of underground space to design deep tank and adopt long-distance composting technology. It makes large-scale innocent treatment of organic waste in limited space come true.
3. It has a compact structure and advanced technology. It adopts unique groove type continuous aerobic fermentation technology to decompose, anhydrate, sterilize and deodorize organic waste and achieve innocent treatment, resourceful treatment and minimization treatment. Besides, it has advantages such as stable product quality and low energy consumption and so on.
4. The groove type compost turning processing of the fermentative material is under intelligentialized auto-control. With the action of lengthways and sideways walking gear, fermentative material is turned over in the tank so that the aerobic fermentation can be completed well.
   
5. The electronic control system of the organic fertilizer compost windrow turner is advanced and reliable. It is easy to operate and equipped with remote control. After the main engine runs, turn spin button to “automatic”, the compost turner will start to work. When it sideways moves to one side, the compost turner will stop moving after touching the limit switch. The compost turner lengthways moves three to five seconds, then sideways moves to the opposite side. This cyclic process achieves the desired effect for compost turning and oxygenating.
6. As for the groove type hydraulic compost windrow turner, except for all features mentioned above, it is manufactured with an additional hydraulic pressure device, with advantages as follows:
   • Hydraulic control system is adopted when manufacturing, by which the organic materials are turned up and down, and mixed with microbial agents more evenly. To some extent, it ensures that every detailed parts in the organic materials are fully contacted with air, hastening the decomposition speed.
   • Electricity saving, and long service life. In some areas, the power shortage situation still hasn’t been eased, so customers are prone to choose a more electricity-saving compost turner. Then our groove type hydraulic organic fertilizer compost turner machine will be your best choice.

Working Principle of Organic Fertilizer Compost Windrow Turner:

1. This organic fertilizer compost turner adopts an integrated structure which consists of reduction drive, material throwing device, walking wheels, walking vehicle. The stand-by work unit is placed on the walking vehicle. There are walking tracks on the fermentation tank. When the machines start to work, the walking vehicle carries the work unit to the fermentation tank to deal with the material. The groove type compost turner is equipped with manual or intelligent time control system to control the work unit.
2. Under the operation of vertically and horizontally walking gear, the high-speed disc harrows throw the fermentative materials up, then fall to the ground and the material shift. The fermented material is carried away and the space is cleared for the material requiring fermentation. Thus a complete fermentation process is formed.
3. The electromotor of the organic fertilizer compost turner machine transfers the power to cycloidal pinwheel speed reducer then to the roller. The stirring blades in the roller are spiral so that the materials in the fermentation tank can be enough stirred and shifted which makes the materials fully catch air and the ferment effect will be better.
