6-bin dynamic batching machine for bio-bacterial fertilizer

The model of the 6-bin dynamic batching machine for biological bacterial fertilizer is HK-DPL-6. It is an automated equipment specially designed by Zhengzhou Hanke Machinery for the production of compound microbial bacterial fertilizer. Its core function is to achieve precise proportioning of biological bacterial agents, organic raw materials (such as livestock and poultry manure, straw), and inorganic raw materials (such as nitrogen, phosphorus, and potassium) through multi-bin independent metering and dynamic mixing technology. The equipment is usually equipped with six independent silos, each of which can store different raw materials. The material flow rate is monitored in real time through electronic belt scales or nuclear scales, and the feeding speed is dynamically adjusted in combination with the PLC control system to ensure that each component is continuously and stably mixed in the preset proportion.

I. Process Flow (6 Steps to Complete

1. Raw material preparation

The six raw materials are respectively loaded into the corresponding silos (such as: organic fertilizer carrier, microbial agent A, microbial agent B, trace elements, conditioner, and auxiliary materials).

2. Dynamic weighing and batching

The system automatically controls the discharging speed of the six silos according to the preset formula.

Incremental type: Each warehouse is weighed separately and mixed in proportion (suitable for main materials).

Reduction type: Real-time monitoring of the weight reduction in the silo (suitable for trace bacterial agents).

3. Mixed conveying

The prepared raw materials are fed into the double-shaft paddle mixer (for uniform mixing without damaging the live bacteria).

The mixing time is adjustable (usually 30 to 60 seconds).

4. Dust removal treatment

Powder is prone to generating dust and requires a pulse dust collector to prevent contamination of the workshop.

5. Packaging or fermentation

It can be directly connected to the automatic packaging machine (valve bag/open bag).

Or enter the fermentation workshop (such as the solid-state fermentation process).

6. Data recording

Automatically store each proportioning data for convenient quality traceability.

Ii. Performance Features (6 Core Advantages

High-precision proportioning: The error of the bacterial agent is ≤0.2%, and the error of the carrier is ≤0.5%, far exceeding manual proportioning.

2. Live bacteria protection design: The bacterial agent tank is fed by vibration or pneumatic conveying to prevent the killing of live bacteria by screw squeezing.

3. Fully automated control: PLC+ touch screen operation, one-click formula switching, saving 3-4 workers.

4. Anti-corrosion material: All contact parts are made of 304 stainless steel, which is resistant to organic acid corrosion (carbon steel rusts and rots within one year).

5. Environmental protection and low dust: Closed design + dust removal system, PM2.5 in the workshop meets the standards.

6. Fault self-check: Automatic alarm for material blockage, out-of-tolerance and power failure to reduce the risk of waste.

Applicable scenarios

To produce bio-bacterial fertilizer (powder/granular), a dynamic ratio of six raw materials is required (such as organic fertilizer carriers, bacterial agents, trace elements, etc.).

High precision is required (the amount of bacterial agent added is small, and the error must be small).

Automated control is needed to reduce manual intervention.

Industry application cases

Production of compound microbial fertilizer

It is suitable for the three-material mixture of biological agents, organic matter and inorganic nutrients to produce granular or powdered bacterial fertilizers that meet the NY/T 798-2016 standard.

Typical case: The complete set of equipment developed by Zhengzhou Hanke Machinery achieves precise proportioning of microbial agents, decomposed straw and fertilizers through a 6-bin dynamic batching machine, with an annual output capacity of up to 50,000 tons.

Processing of organic-inorganic compound fertilizers

During the process of fermenting livestock and poultry manure to make fertilizer, the dynamic batching machine can add auxiliary materials such as mineral powder and bentonite in proportion to improve the physical properties of the fertilizer.

Data support: The 6-bin model of Zhengzhou Hanke Machinery is widely used in the resource utilization project of manure and sewage in livestock farms, with a single-line production capacity of up to 6 tons per hour.

Production of BB fertilizer (blended fertilizer)

Support the dynamic blending of basic fertilizers such as nitrogen, phosphorus and potassium to meet the nutritional needs of different crops and reduce the loss of fixed nutrients.

Core configuration of the 6-warehouse dynamic batching machine

Weighing method

Incremental batching (commonly used) : Each bin is weighed separately, and materials are discharged in sequence according to the formula, with high precision (±0.1% to 0.3%).

Reduced-dose batching (high-end) : Real-time monitoring of weight changes in the silo, suitable for trace additions (such as bacterial agents), with higher precision (±0.05% to 0.1%).

Recommendation: Incremental type (economical and practical). If the amount of bacterial agent added is very small (<1%), a separate reduction scale can be provided.

(2) Feeding method

Ingredients method: Suitable materials: Advantages: Disadvantages: Price

Spiral feeding: Powder, fine granules (carrier for bacterial fertilizer) : Good sealing, no dust raised; may squeeze live bacteria (choose low-speed model); Medium range (50,000-150,000 yuan)

Vibrating feeding: Granules, powder with good fluidity; does not harm bacteria, suitable for live bacteria preparations; generates a lot of dust, requires dust removal; low grade (30,000-100,000 yuan)

Belt scale: Granules, coarse powder: Suitable for large flow of raw materials (such as organic fertilizer base materials); relatively low accuracy (±0.5%); low grade (40,000-120,000)

Recommended combination

Four spiral feeding bins (main raw materials, such as organic fertilizer, straw powder, etc.)

One vibrating feeding bin (for bacterial agents, to avoid the activity of screw extrusion)

One micro-reduction scale (such as trace elements, pH regulators)

(3) Control system

PLC+ touch screen: It can store multiple formulas, switch with one click, and is suitable for multi-variety production.

Data recording: Record each ingredient data for convenient quality traceability (Bio-fertilizer has high requirements and is a must-have!) .

Linked packaging machine: It can be connected to an automatic packaging line to achieve full automation from batching to mixing and packaging.

Mandatory features

Formula Management (Store at least 20 formulas)

Automatic calibration (Errors may occur after long-term use, automatically corrected)

Alarm function (blockage and out-of-tolerance reminder)

2. Price reference for 6-bin dynamic batching machine of bio-bacterial fertilizer

Configuration: Price range: Suitable for enterprises

Basic model (6-screw, incremental, ordinary PLC) : 80,000-150,000 yuan for small and medium-sized bacterial fertilizer factories

3. A Guide to Avoiding Pitfalls When Purchasing a 6-Bin Dynamic Batching Machine for Bio-Fertilizer

1. Don't buy pure belt scales: They are not precise enough and can't mix the bacterial agents accurately!

2. Avoid using a screw in the bacterial agent tank: High-speed rotation may kill the live bacteria. Choose vibration or pneumatic conveying!

3. Material should be 304 stainless steel: Biological bacterial fertilizer is highly corrosive, while carbon steel will rust after long-term use!

4. Test run! Test run! Test run! Take your raw materials and have the manufacturer test them on site to see if there is any error in the actual proportioning!

Summary: Which 6-tank dynamic batching machine for bio-fertilizer should I buy?

Small factory/Low budget → Basic 6-spiral incremental type (80,000-150,000)

Formal microbial fertilizer factory → 5 screws +1 vibration + micro scale (150,000-250,000)

Export/High Requirements → Fully reduced batching + Intelligent System (250,000 +)

Remember: The most crucial aspects of bio-fertilizer ingredients are the precision of the bacterial agent and the protection of its activity. Don't just focus on the price!
