Compound fertilizer cooler structure
Compound Fertilizer Rotary Cooler is a kind of equipment used to produce compound fertilizer. It can be different according to the specific design, and generally consists of the following parts: riding ring, waist gear, support device, pinion gear, cover, gear cover, shell, transmission device, and so on.
Cooler Shell
The cooler shell is a thick, steel cylindrical structure providing strength and rigidity to withstand high temperatures. It contains materials and gases during cement manufacturing. Inside, it has refractory lining, usually bricks or castable, for insulation. Tongli cooler shells have smooth edges for enhanced sealing and extended service life.
Cooler Flights
Cooler flights, or lifters, are inclined, curved structures inside the rotary cooler. These flights lift and drop materials as the drum rotates, aiding in moisture removal through cooling.
Riding Rings (Tyres)
Riding rings, usually 2-3 per cooler, support the shell and facilitate smooth rotation. These rings are point-welded with padding for added strength and weight distribution.
Girth Gear
The girth gear is a large ring gear mounted on the cooler shell, driven by a pinion gear to rotate the cooler. It forms the primary drive unit.
Supporting Device
The supporting device consists of supporting and thrust rollers, made in-house for guaranteed quality. These rollers are machined and heat-treated for reliable performance.
Thrust Roller
The thrust roller supports the cooler’s weight and maintains axial alignment. Positioned on the downhill side, it ensures proper alignment during rotation.
Bearing Housing
The bearing housing supports the cooler’s trunnion bearings, which allow smooth rotation under high loads and temperatures. It ensures proper alignment and stability.
Transmission Device
The transmission device includes main and auxiliary transmissions, mechanical/hydraulic thrust rollers, motor, and gearbox. Tongli’s design enhances equipment lifespan and safety.
Cooler Hood Cover
Located at the discharge end, the hood cover seals heat and gases. Tongli uses SS304 lining and ceramic felt to prevent heat leakage, maintaining negative pressure operation.
PLC Control System
The PLC system monitors and controls critical parameters like temperature, rotation speed, and air flow. Integrated with the factory’s PLC system, it ensures optimal cooler performance and product quality.
