Precise Compact Durable Reliable

Lime powder dosing system delivers precise, dust‑free volumetric dosing up to 500 L/h for water treatment, ensuring consistent pH control and reduced chemical waste. Its compact screw-and-silo shape, epoxy‑coated carbon steel construction (stainless steel optional), integrated bag filter and pneumatic conveyor combine hygienic, easy-to-clean style with durable, low‑maintenance quality. Supplied in standard export carton packing, available with inlet-water control and dissolving-tank options, and backed by 1‑year support with 3–20 day delivery to get your plant running quickly.

Option 1: Compact Precision 500L/h Dosing

The Small Volumetric Dosing Screw Feeder functions as a Lime powder dosing system for water treatment plants, offering silo volumes from 10–100 m3 and dry dosing rates of 50–2000 L/h, with carbon-steel epoxy construction and stainless-steel options plus add-ons like inlet water control, lime dissolving tank and mixers. Its pneumatic transport, bin-bottom activation, metering screw and bag filter provide accurate, low-dust volumetric dosing and automated feeding to reduce chemical loss and maintenance while ensuring stable pH control and sludge conditioning. The modular screw-silo-dissolving-tank layout, compact floor footprints across models and robust build deliver easy installation, scalability and long-term reliability for industrial chemical dosing applications.

Compact 500L/h Dosing Feeder

The Small Volumetric Dosing Screw Feeder designed for water treatment plants serves as a reliable Lime powder dosing system, handling large quantities of dry chemicals such as lime with dosing rates from 50 to 2000 L/h. It features pneumatic transport to minimize dust, a silo (10–100 m3) with bin-bottom activation, powder metering and transporting devices, and a bag filter for clean operation. Constructed from carbon steel with epoxy paint (stainless steel optional), the unit can be fitted with inlet water control, lime dissolving and mixing tanks, and multiple capacity options to meet varied treatment needs.

Accurate Compact Durable Efficient

Built by a water-treatment specialist with a one-year warranty for small municipal and industrial plants, the Small Volumetric Dosing Screw Feeder 500L/h was engineered for dependable dry-chemical handling and serves as a core Lime powder dosing system. It meters lime powder up to 500 L/h using a precision auger and variable-speed drive, with corrosion-resistant construction, dust-tight hopper, and modular components for easy maintenance. Key advantages include high volumetric accuracy, anti-bridging feed geometry, quick-change wear parts, compact footprint, PLC-ready controls for remote monitoring, and energy-efficient operation that minimizes downtime and chemical waste.

Material introduction

The Small Volumetric Dosing Screw Feeder is built from carbon steel with an epoxy paint finish as standard, with stainless steel construction available as an option for more corrosive or hygienic applications. Critical components — including the wear‑resistant dosing screw, bin‑bottom activation device, powder metering and pneumatic conveying assemblies, and bag filter — use abrasion‑ and lime‑resistant materials and seals to minimize wear, dust and maintenance. As a Lime powder dosing system for water treatment plants, it combines robust, easy‑to‑clean surfaces and upgradeable stainless‑steel contact parts to ensure long service life and reliable metering.

FAQ

What is the Small Volumetric Dosing Screw Feeder 500L/h typically used for?

It is used to meter free‑flowing powders and granules into water treatment and process streams at a controlled volumetric rate. Common applications include feeding coagulants, polymers, activated carbon, lime, powdered chemicals and other solids into dissolvers, mixing tanks, pipelines or reactors in municipal and industrial water/wastewater plants, swimming pool systems, and small process plants.

What materials can it handle and what is the dosing capacity?

The feeder is designed for free‑flowing powders and granules (non‑sticky, non‑caking). The nominal volumetric capacity is up to 500 L per hour; actual mass flow depends on bulk density of the material. Very cohesive or wet materials may require special hopper agitation or an alternative feeding technology.

How do I install and integrate the feeder into my water plant controls?

Mount the unit on a stable frame above the receiving point (dissolver, hopper or transfer auger). Connect the motor to the electrical supply and, if needed, to a variable speed drive (VFD) or the plant PLC for remote speed control. Typical integration options include start/stop, analog speed command (4–20 mA), and feedback signals. Route the feed outlet into a dissolving tank or metering pump suction as required by your process. Follow local electrical and mechanical installation codes.

How accurate is the dosing and how do I calibrate it?

Volumetric accuracy depends on material bulk density and feedability; under typical conditions you can expect repeatable dosing within a few percent (often ±2–5%). Calibrate by running the feeder at a chosen speed for a measured time, collecting and weighing (or measuring volume) of product discharged, then adjust the speed setpoint or create a speed-to-flow lookup table for the material. Repeat calibration when material, humidity or hopper fill level change.

What routine maintenance is required to keep performance reliable?

Daily/operational checks: inspect for bridging, verify hopper level and discharge, listen for unusual noises. Weekly/monthly: clean hopper and screw if changing chemicals, check and tighten fasteners, inspect bearings and seals. Lubricate bearings as recommended by the manufacturer and replace wear parts (screw, liner, seals) when worn. Keep records and service more frequently for abrasive or corrosive materials.

What safety and compatibility issues should I be aware of?

Verify chemical compatibility of contacting parts (stainless steel options available for corrosive powders). Manage dust and explosion risks: use grounding/earthing, dust extraction or enclosures, and explosion‑rated motors where required. Provide appropriate PPE and follow MSDS guidance for handled chemicals. The unit typically comes with a 1‑year warranty for normal water plant use—confirm specifics with the supplier.
