What is the working principle of the Shicang water-soluble fertilizer loss-in-weight static batching

The ten-warehouse water-soluble fertilizer loss-in-weight scale is a powerful tool for "precise feeding and stable production", suitable for enterprises with high requirements for formula accuracy. However, the model should be selected in combination with the budget and actual needs.

I. Working Principle of the ten-compartment water-soluble Fertilizer Loss-in-weight Static Batching Scale

The core of the loss-in-weight static batching scale is "weighing while feeding", which precisely controls the feeding amount by monitoring the weight changes of the materials in real time. Take Shicang water-soluble Fertilizer as an example:

Initial weighing: The materials in each silo (such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, etc.) are weighed first, and the initial weight is recorded.

Continuous feeding: Start the feeding equipment (such as a screw feeder), and the material will continuously flow out from the silo.

Dynamic monitoring: High-precision sensors monitor the weight changes of the silo in real time. The system calculates the actual feeding speed based on the weight reduction per unit time (i.e., "weight loss").

Closed-loop control: Compare the actual feeding speed with the preset value, and dynamically adjust by regulating the rotational speed of the feeding equipment (such as controlled by a frequency converter) to ensure the accuracy of the feeding amount.

Feeding mechanism: When the weight of the silo drops below the lower limit, feeding will automatically stop and feeding will be triggered. After the feeding is completed, the cycle will continue.

Key points:

Static weighing + dynamic control: When feeding, the silo is in a "suspended" state, avoiding external vibration interference and achieving higher accuracy.

Independent control of multiple warehouses: Ten warehouses can operate simultaneously without interfering with each other, making it suitable for complex formulas.

Applicable scenarios: In the production of water-soluble fertilizers, multiple raw materials need to be mixed in proportion. The loss-in-weight scale can avoid the errors caused by the differences in material fluidity in traditional equipment.

Ii. Price Characteristics

Price range:

Basic model: The single-chamber loss-in-weight scale is approximately 10,000 to 50,000 yuan, and the total price of the ten-chamber equipment is about 100,000 to 500,000 yuan (depending on accuracy, material, etc.).

High-end model: Equipped with explosion-proof, corrosion-resistant design or high-precision sensors (such as 0.1% grade), the price may double.

Factors influencing the price:

Precision requirement: The higher the precision (such as ±0.2% vs ±0.5%), the more expensive the price.

Material: The parts in contact with materials are made of 304/316L stainless steel, which is more expensive.

Function expansion: such as data traceability, remote monitoring, multi-formula storage, etc., increases costs.

Cost performance:

The initial investment in a loss-in-weight scale is high, but in the long run, it can reduce raw material waste (with small errors) and is suitable for large-scale production.

Compared with traditional screw scales or belt scales, the maintenance cost of loss-in-weight scales is lower (with no mechanical wear parts).

Iii. Summary

Working principle: By monitoring the weight changes of the silo in real time and dynamically adjusting the feeding speed, high-precision batching is achieved.

Price features: The total price of the ten-warehouse equipment is approximately 100,000 to 800,000 yuan, which is affected by precision, material and function.
