Weigh Belt Feeder
The LCS‑D series weigh‑belt feeder is designed for batching non‑cohesive materials such as limestone, clinker, sand & gravel, shale, gypsum and coal.
Developed based on Schenck Germany technology, this metering equipment integrates our patented anti‑impact structure and AI dynamic algorithm.
System accuracy: ≤1%.
Product Overview
Also known as belt dosing scale, LCS-D/F/N series weigh belt feeder is engineered for dynamic weighing, totalization and closed-loop flow control during bulk material conveying. It delivers precise quantitative feeding for ores, granules, powders and other bulk materials across metallurgy, construction material, chemical and food industries.
This feeder comes in 4 structural types: open type, semi-enclosed type, fully enclosed type and pressure-resistant type. Its throughput ranges from 50kg/h to 1200t/h, belt width from 300mm to 2000mm, and machine length from 1m to dozens of meters. Custom enclosure solutions are available for dust-proof, explosion-proof and sealed working environments to match various site conditions.
The LCS‑F Series Weigh Belt Feeder
Matched with electrical control cabinet and industrial computer, it forms a complete automatic batching control system with full functions: real-time data acquisition, automatic flow adjustment, fault alarm, production curve display and historical data storage & management, realizing full-automatic material proportion control and production data traceability.
Working Principle
The metering and control process of weigh belt feeder runs fully continuous and automatically without constant manual operation, which can complete startup/shutdown, real-time weighing and constant flow control autonomously.
- Bulk material falls onto the conveyor belt from silo or upstream feeding equipment;
- Weighing bridge collects load weight signal in real time, while speed sensor synchronously detects belt running speed signal;
- Both signals are transmitted to totalizer controller simultaneously. After calculation, instantaneous flow rate and cumulative total weight are displayed on local panel;
- The controller compares measured actual flow rate with preset target flow rate, and outputs regulating signal to frequency converter based on deviation value;
- Frequency converter adjusts the rotating speed of driving geared motor to change belt velocity, forming closed-loop correction of feeding volume to maintain stable constant feeding flow.
