This shipment covers a complete set of agitating tank and product silo, which are key auxiliary units supporting the controlled-release fertilizer production line. The agitating tank serves as the preparation station for coating liquid, while the product silo is used for temporary storage, buffering and feeding of finished coated fertilizer granules. Matching with the fluid bed coater system, they form a stable material preparation and finished product storage module, ensuring continuous and orderly operation of the whole CRF plant. Both pieces of equipment are designed according to agricultural chemical working conditions, featuring good corrosion resistance, reliable structural strength and convenient operation and maintenance.
The agitating tank adopts vertical cylindrical structure. All wetted parts in contact with coating solution are made of 316L stainless steel, and the outer shell and supporting legs are 304 stainless steel. It is equipped with a low-speed stirring assembly, which can fully mix polymer coating materials, additives and solvent evenly without local precipitation or agglomeration. The stirring speed can be adjusted to adapt to different viscosity of coating formulas. Optional jacket structure is available for heating or heat preservation, so as to keep the coating liquid at a stable temperature and maintain good atomization performance during subsequent spraying. Sight glass, liquid level gauge, feeding port, discharge outlet, overflow port and cleaning port are reserved on the tank body. All internal welds are finely polished to reduce dead corners and facilitate CIP cleaning. Seals of the stirring shaft adopt wear-resistant and chemical-resistant packing or mechanical seal to prevent liquid leakage.
The product silo is designed for bulk storage of finished fertilizer pellets. The main silo body is made of 304 stainless steel, with a conical hopper at the bottom to achieve smooth material discharging and avoid bridging and arching of granules. A vibration device can be fitted optionally to assist material flow when necessary. The top of the silo is equipped with a breathable dust filter to prevent dust escaping during material feeding while balancing internal and external air pressure. Inspection manhole is arranged for regular internal checking and cleaning. Supporting legs are reinforced to bear full load of stored materials. Discharge valve at the bottom controls the output of finished materials, which can be connected to packaging equipment or conveying system. The surface of the silo is treated with polishing, smooth and not easy to stick fertilizer particles.
Before packaging and delivery, strict factory inspection and function test have been carried out. The dimensional check of tank and silo body is completed to confirm compliance with drawing requirements. The stirring mechanism runs continuously for a test period to verify stable rotation, no abnormal noise and no shaft swinging. Air tightness test and water leakage test are performed on the agitating tank to check the sealing performance of all ports and shaft seals. The load-bearing structure of the product silo is inspected to confirm structural safety under full material load. All instruments including liquid level sensors and pressure gauges are calibrated. All valves and movable parts are operated repeatedly to guarantee flexible opening and closing. Test records and material certificates are sorted into the delivery document package.
For packaging protection, stainless steel surfaces are covered with anti-scratch protective film. Flange faces, threaded ports and sealing surfaces are protected by plastic caps to avoid bump damage and foreign matter entering. The agitator motor, reducer, sensors and precision valves are individually wrapped with shockproof bubble film and packed in separate wooden boxes. All loose accessories, gaskets, bolts, connecting pipe fittings and special tools are placed in marked spare part boxes. The large tank and silo sections are fixed on reinforced export fumigation-free wooden skids, filled with foam and stretch film for fastening. Standard shipping marks including upward, moisture-proof, fragile and center of gravity marks are clearly printed on the outer package.
Shipping documents include commercial invoice, packing list, material certificate of stainless steel, factory inspection report, operation and maintenance manual, assembly drawings and connection schematic diagrams. All documents are prepared to meet international customs clearance requirements, helping the buyer complete import declaration and inspection smoothly at destination. During container loading, heavy components are placed at the bottom and evenly distributed. Cargo is fixed by binding belts and wooden bracing to prevent shifting, collision and deformation during sea transportation. Lifting operation must follow the marked lifting points to avoid structural deformation.
After arrival, the buyer can arrange unpacking inspection and check against the packing list. Our technical team can provide remote guidance for on-site assembly, foundation fixing, pipeline connection and electrical wiring. We will explain installation points such as level adjustment of the agitating tank, sealing check of stirring shaft, silo anti-bridging adjustment and interconnection with upstream and downstream equipment. Training covers daily operation, regular cleaning, seal replacement, reducer lubrication and common fault handling.
The warranty period for main structures follows the agreed terms. Wearing consumables such as shaft seals, filter elements and gaskets are not covered by warranty. Damage caused by improper hoisting, wrong installation, corrosion from incompatible media and man-made impact is excluded. We keep supplying long-term technical support and spare parts supply service.
This shipment of agitating tank and product silo complements the fluid bed coating system. After proper installation and commissioning, it will realize stable coating liquid batching and finished fertilizer buffering storage, supporting the whole CRF plant to run continuously and steadily and helping the customer achieve efficient controlled-release fertilizer production.
