The equipment configuration of fertilizer production line directly affects product quality and production efficiency. Whether producing organic fertilizers, compound fertilizers, or biological fertilizers, a series of professional equipment are required for collaborative operation. This article will systematically introduce the key equipment and its functions in fertilizer production lines, helping you understand the core equipment of modern fertilizer production.
1、 Raw material pretreatment equipment
Flipping machine
Function: Used for aerobic fermentation of organic materials, promoting oxygen exchange and water evaporation through flipping.
Type:
Slot type stacker: suitable for fixed fermentation tanks, with a processing capacity of 10-30 tons/hour.
Crawler type compost turning machine: suitable for outdoor composting, with a turning depth of up to 2 meters.
Advantages: High degree of automation, which can effectively shorten the fermentation cycle (from 60 days to 20-30 days).
crusher
Function: Crush raw materials (such as animal manure and straw) to a suitable particle size (usually 3-5mm).
Common equipment:
Semi wet material crusher: processes raw materials with a moisture content of ≤ 30% to avoid clogging.
Chain crusher: suitable for coarse crushing of compound fertilizer raw materials (such as phosphate).
2、 Mixing and batching equipment
Mixing machine
Dual axis blade mixer: mixing uniformity ≥ 95%, can add microbial agents or trace elements, with a production capacity of 5-20 tons/hour.
Vertical mixer: suitable for small-scale production, small footprint, low energy consumption.
Automatic batching system
Electronic belt scale: dynamic batching accuracy ± 0.5%, combined with PLC control to achieve precise nitrogen phosphorus potassium ratio.
Micro addition device: used for quantitative addition of functional microbial agents in biological fertilizers.
3、 Granulation molding equipment
Disc Pelletizer
Features: Low investment, simple operation, suitable for small and medium-sized production lines, adjustable particle diameter of 2-8mm.
Applicable materials: Organic fertilizers, compound fertilizers, and other raw materials with good viscosity.
Features: Continuous production, high production capacity (up to 50 tons/hour), high particle roundness.
Application: High tower granulation of compound fertilizers or production of urea based fertilizers.
Flat die extrusion granulator
Features: No need for drying, direct cold pressing molding, suitable for the production of bio organic fertilizers.
Advantage: Low temperature process protects microbial activity.
4、 Drying and cooling equipment
Rotary Dryer
Function: Reduce the moisture content of particles from 25% -30% to ≤ 15%.
Heat source selection: coal, natural gas or biomass fuel, modern equipment thermal efficiency can reach 80%.
Cooling and screening integrated machine
Workflow: Particles are classified through a vibrating screen (4-6 mesh) and forced to cool to room temperature by a fan.
Function: To prevent clumping of finished products and improve storage stability.
5、 Packaging and auxiliary equipment
Automatic Packaging Machine
Type:
Valve pocket packaging machine: accuracy ± 0.2%, speed 800-1200 bags/hour.
Ton bag packaging machine: used for large capacity (500-1000kg) bulk fertilizers.
Dust removal system
Cyclone dust removal+water film dust removal: Ensure that the dust concentration in the production workshop is ≤ 10mg/m ³, which meets environmental protection requirements.
intelligence control system
Function: Real time monitoring of temperature, humidity, production and other data to achieve remote fault diagnosis.
6、 Equipment selection suggestions
According to the selection of raw materials:
Mainly for livestock and poultry manure: priority should be given to configuring a stacker+chain crusher.
Straw raw materials: Additional pre-treatment with a grass cutting machine is required.
Select based on production capacity:
Small scale production line (annual output of 10000 tons): with an investment of approximately 800000 to 1.5 million yuan, centered around a disc granulator.
Large scale production line (with an annual output of 100000 tons): requires a drum granulator and automated packaging system, with an investment of over 5 million yuan.
Energy saving design:
The use of waste heat recovery devices can reduce drying energy consumption by 30%.
The modern fertilizer production line has achieved a high degree of mechanization and intelligence. Reasonable equipment configuration can not only improve product quality, but also reduce energy consumption and labor costs. It is recommended that enterprises conduct raw material testing and process demonstration before investment, and choose equipment solutions that match their own needs. In the future, with the popularization of IoT technology, fertilizer production will further move towards "unmanned workshops".
