Disc pelletizer granulation production line
The simplified disc granulator granulation production line is generally used for a small number of raw materials, generally less than 2 kinds of raw materials, and the ingredients do not require strict proportion requirements. The main equipment of this production line is the disc granulator and drying equipment. Because the disc granulator uses water spray granulation, the granules produced contain high moisture, which requires drying equipment to remove.
Processing mineral powders (such as calcium carbonate, talc, and bentonite) into granules through disc granulation is a key process for addressing issues such as dust generation, low transportation efficiency, and inconvenience. The "Simplified" solution, centered around low cost, high adaptability, and ease of operation, focuses on core functions and simplifies non-essential auxiliary systems. It is suitable for small to medium-sized production capacities (typically 10,000-50,000 tons/year) with moderate requirements for granule quality, such as fertilizer carriers, building material supplements, and feed additives. The following describes the production line's composition, process flow, key parameters, advantages, and considerations.

Key parameters
|
Adjustment principles
|
|
Disc granulator
|
Diameter 1.8-2.5m, speed 15-20r/min, inclination 35°-55°
|
High production capacity demand → choose a large diameter disc; mineral powder is very sticky → reduce the speed and increase the inclination angle; low viscosity → increase the speed and reduce the inclination angle
|
|
Screener machine
|
Mesh aperture 0.8-3mm, vibration frequency 1500-3000 times/min
|
Small particles required → small sieve holes (0.8-1.5mm); large particles required → large sieve holes (2-3mm); low vibration frequency → slow screening but not prone to clogging
|
|
Binder addition amount
|
3%-8% (mass ratio of mineral powder)
|
Talc powder, calcium carbonate powder (weak viscosity) → 5%-8%; bentonite, kaolin (strong viscosity) → 3%-5%; "non-scattering particles and non-sticking to the plate" as the standard
|
Granule packaging machine: It adopts automatic bag sewing machine, and can also be replaced with manual bag folding and sewing according to needs.
The main advantages of fertilizer production line:
①The production line adopts Disc pelletizer, which is easy to operate and can be operated without professional training.
② The use of flexible belt conveyor equipment maintains the integrity of the particles and does not destroy the particle structure during the conveying process.
③The overall structure adopts one-button start and stop, which is easy to operate and maintain.
④ It adopts 3-bin automatic batching equipment with high batching accuracy, keeping the error within ±0.2%.
