Accurate High-capacity Compact Durable

The QPL3 powder dosing machine delivers reliable 500 L/h automatic lime dosing with PLC control and touch-screen feedback, ensuring precise feed rates and consistent treatment results to avoid chemical waste. Built from SUS304 stainless steel with a compact, attractive shape and industrial styling, it provides durable, easy-to-clean quality for low-maintenance operation. Standard export carton packaging and modular dimensions simplify transport and installation, while the motor-driven metering feeder with adjustable speed guarantees exact dosage for municipal and industrial sludge conditioning.

Automated PLC 500L/h Dosing

The QPL3 powder dosing machine is an automatic PLC-controlled lime powder dosing system with a motorized metering feeder and 500 L/h capacity, constructed from SUS304 and designed for precise, repeatable powder delivery. It provides variable-speed, highly accurate powder metering with touch-screen status output to ensure consistent dilution for sludge dewatering and chemical dosing, reducing waste and labor. Compact dimensions, a large hopper, imported components and easy-maintenance design deliver reliable long-term performance for wastewater treatment with a one-year quality guarantee.

Automatic PLC Lime Doser

The QPL3 powder dosing machine is an automatic lime powder dosing system with PLC control and a 500 L/hr production capacity (model QPL3-500), built from SUS304 stainless steel and high-quality imported components for dependable performance. It delivers precise powder feeding via a variable-speed metering feeder, provides touch-screen messaging to prevent waste, and efficiently dissolves powders like PAM and PAC. Suited for municipal and industrial sewage conditioning and sludge disposal, the unit is offered in multiple models with standard export packing and typical delivery within 3–20 days.

Accurate Efficient Durable Automated

Built by a decades‑old industrial automation brand focused on reliability, the QPL3 powder dosing machine was engineered with robust materials and PLC control to deliver precise lime dosing backed by a one‑year warranty. Its motorized feeder and intelligent PLC deliver up to 500 L/h, automatic calibration, real‑time monitoring and dust‑control for minimal waste and seamless integration into existing lines. Key features include stainless steel construction, adjustable dosing rates, sealed hopper, user‑friendly HMI and remote diagnostics, with advantages of high accuracy, low maintenance, easy cleaning, energy efficiency and rapid ROI.

Material introduction

The QPL3 powder dosing machine is built with a SUS304 stainless steel crust and high-quality imported parts to provide strong corrosion resistance and durable performance when handling lime powder. For more aggressive or contaminant-sensitive powders, polypropylene (PP) construction options are available to ensure chemical resistance and product purity. Corrosion-resistant motor mounts, PLC housings, and precision metering components further enhance reliability and reduce maintenance for continuous dosing operations.

FAQ

What kinds of processes and industries is the Automatic PLC Lime Powder Dosing Machine (500 L/h) typically used for?

This machine is designed for continuous, controlled dosing of lime powder (usually hydrated lime) and is commonly used in municipal and industrial wastewater pH control, sludge conditioning, flue-gas desulfurization (FGD), chemical neutralization, and batch/mortar production in construction. It can also be used wherever stable, volumetric lime addition is required — for example in mining, paper mills, and some food-processing water-treatment lines.

How does the machine control dosing and how accurate is it?

Dosing is controlled automatically by a PLC that adjusts the motor-driven feeder (typically an auger or metering screw) according to a set rate. Accuracy depends on powder bulk density, particle size and moisture, and system calibration; after proper calibration most volumetric lime dosing systems achieve consistent results (commonly within about ±1–3% of the set rate). For best accuracy, calibrate with the actual material and integrate the PLC with process feedback (flowmeters, pH probes) if closed-loop control is needed.

My lime powder tends to cake or contain moisture. Can this machine handle wet or agglomerated lime?

The machine is designed for free-flowing powdered lime. High moisture or heavily caked material will reduce dosing consistency and can block the feeder. To handle sticky or damp lime you should: (1) store material in a dry environment or use dehumidified storage; (2) use pre-conditioning (sieving, breaking) or an agitator in the hopper; (3) consider heating or air-drying systems for severe cases; and (4) consult the supplier about hopper agitators, anti-bridging inserts or forced-air systems that reduce bridging and maintain consistent feed.

What installation, utilities and integration requirements should I prepare for?

Prepare a level, sturdy mounting surface and adequate space for the hopper, feeder and access for maintenance. The machine requires an electrical supply for the PLC and motor — voltage and phase are typically configurable (confirm with supplier; common options are 220/380/400 V at 50/60 Hz). Provide suitable dust extraction or local ventilation for powder-handling areas and route signal wiring if you want integration with plant control systems (analog I/O, Modbus/Profibus, or relay contacts — confirm PLC communication options). Grounding and earthing per local electrical codes are required. Also plan for material feed (bag tip or bulk inlet) and a safe routing for discharged lime into downstream equipment.

What routine maintenance is required and what does the 1-year warranty cover?

Routine maintenance includes daily visual checks, weekly cleaning of the hopper inlet and discharge, periodic inspection and lubrication of moving parts per the manual, and checking drive belts/fasteners. Replace wear items (auger, seals, bearings) as they show wear. The typical 1-year warranty covers manufacturing defects in materials and workmanship under normal use; it usually excludes normal wear parts, damage from improper installation/operation, corrosion from incompatible chemicals, and damage from lack of maintenance. Always check the supplier’s specific warranty terms for exact coverage and claim procedures.

What safety and environmental controls should operators follow when using this machine?

Lime powder is alkaline and can irritate skin, eyes and respiratory tract. Provide appropriate PPE (dust masks/respirators rated for fine particulates, goggles, gloves, and protective clothing). Install local dust extraction or a bag-filter system to minimize airborne dust. Ensure emergency stop and lockout/tagout procedures are implemented for maintenance. Avoid creating ignition sources near dust clouds (follow local combustible dust regulations even though lime is not typically highly combustible). Train operators in safe handling, spill cleanup, and first-aid measures for lime exposure.
