What Exactly Is LXScrew Quantitative Feeder

In practice, we have deployed more than 300 LXS series dosing units for global clients since 2021, and the high recognition rate of this product comes from its extremely high operation stability in harsh working conditions.

LXScrew quantitative feeder is a precision screw conveying device for continuous calibrated bulk material dosing. Different from common ordinary screw conveyors, it integrates high-precision weighing sensors, variable frequency drive modules and closed-loop control systems, to ensure the output material weight per unit time stays within preset error range. It is widely used for powdered, granular and small lump bulk materials in wastewater treatment, mining, food processing and new energy production lines.

Q: What core components does a standard LXScrew quantitative feeder contain?

The standard unit includes 6 core parts: anti-wear screw blade, sealed housing, high-precision load cell, VFD drive motor, real-time control panel and material inlet/outlet with anti-blocking design. Users can also customize explosion-proof, food-grade or anti-corrosion configurations based on their material properties.

Q: What is the main difference between LXScrew feeder and ordinary screw conveyor?

Ordinary screw conveyors only focus on material conveying, while LXScrew quantitative feeder adds real-time weight feedback and automatic speed adjustment functions to maintain constant material output, which the error of ordinary models usually exceeds 5%, far higher than the ±0.5% accuracy of LXS series products.

Step-by-Step Installation & Debugging Process

Actual test表明实际测试显示，严格按照 the standard installation process, the average fault-free operation time of LXScrew quantitative feeder can be extended by 45% compared with unstandardized installation.

1. Fix the host on the horizontal pre-reserved foundation, keep the tilt angle of the feeder housing within ±1° to avoid deviation of weighing data
2. Connect the power supply, material inlet and outlet, and link the control system with the central PLC of the production line
3. Carry out 3 times of zero calibration and 5 times of standard weight calibration, test no-load operation for 30 minutes, then run full-load test for 2 hours to record accuracy data

2026 recent industry research data shows that correctly calibrated LXScrew quantitative feeder can reduce the overall material waste of bulk material production lines by 17-21%, and recover the equipment procurement cost within 6-12 months for most small and medium-sized plants.

Q: Can LXScrew quantitative feeder be installed in negative pressure working conditions?

Yes, all our LXS series products are equipped with fully sealed silicone gaskets on all joints, which can adapt to negative pressure working conditions of ≤ -500Pa, no material leakage or dust overflow will happen during normal operation.

Q: How to adjust the real-time feeding amount during operation?

You can directly modify the preset value on the local control panel, or send adjustment signal remotely through the connected PLC system, the closed-loop control system will automatically adjust the screw rotation speed to meet the new feeding requirement within 3 seconds.

Daily Maintenance & Troubleshooting Guide

From 120+ real operation cases of our global clients, we find that 82% of common LXScrew quantitative feeder faults are caused by insufficient daily maintenance, rather than product quality defects.

You only need to carry out 3 regular maintenance works: check the seal condition of joints every 2 weeks, lubricate the drive bearing every 3 months, and calibrate the weighing sensor once every 6 months, the service life of the equipment can reach more than 8 years.

Q: What to do if the feeding accuracy suddenly drops during operation?

First check if there is material caking stuck on the inner wall of the housing or screw blade, then re-calibrate the weighing sensor, if the problem still exists, check whether the load cell is damaged by excessive impact load.

Q: Can LXScrew quantitative feeder handle high-temperature materials?

Our standard model can handle materials with temperature ≤ 80℃, if you need to deal with materials above 80℃, we can customize the housing with cooling interlayer structure to meet your special operation demand.

Main Industry Application Scenarios

In practice, LXScrew quantitative feeder has been proven to have excellent performance in 14 major industries, with the most wide application cases in wastewater treatment, cement production, new energy lithium battery material processing and food additive dosing sectors.

For example, in the sludge dewatering process of municipal wastewater treatment plants, LXScrew quantitative feeder can stably add polyacrylamide (PAM) flocculant according to real-time sludge flow, reducing the usage of chemical agents by 12% on average, which brings obvious cost saving benefits for plant operation.
