The mixed fertilizer production line equipment is generally a complete set of devices that measure, mix, and package several elemental fertilizers or compound fertilizer raw materials (such as urea, diammonium phosphate, potassium chloride, etc.) in a certain proportion. Compared with the traditional compound fertilizer granulation process, it belongs to the physical mixing process, does not require high-temperature chemical reactions, has low investment, low energy consumption, and fast results.
1、 Main components of mixed fertilizer production line equipment
Automatic batching system
Including multiple raw material silos (hoppers/bins)
Equipped with electronic measuring scale and variable frequency speed control conveyor device
Realize precise automatic ingredient dispensing according to the formula
Bucket elevator/conveying equipment
Used to transport materials from the storage bin to the mixing system
Common types include belt conveyors and screw conveyors
Fertilizer mixer (blender)
Core equipment of production line
Structures include: horizontal screw belt mixer, dual axis gravity free mixer, rotary drum mixer, etc
Require uniform mixing, fast speed, and no damage to particles
packaging machine
Automatic weighing and packaging machine (usually 10-50kg/bag)
Configure automatic sewing/heat sealing machine
control system
PLC control, formula programmable
Equipped with automatic metering, mixing, and bagging functions
Can be connected to a computer to achieve remote recipe management
Dust removal and environmental protection devices
Bag filter, bag filter
Reduce dust pollution
2、 Process flow
Raw materials (nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer+trace elements) → raw material warehouse → batching system measurement → transportation → rapid mixing by mixer → finished product warehouse → automatic weighing and packaging → finished product storage
3、 Capacity Range
Small scale: 5-10 tons/hour (suitable for local fertilizer factories, customized formulas)
Medium size: 20-30 tons/hour
Large scale: 40-60 tons/hour (continuous production, high degree of automation)
