ZTZZC1200 Rotary Weigher Helps Yunnan Cement Plant Solve the Metering and Conveying Challenge of 70 Tons of Lignite

Project Overview

Weifang Zhitian provided a complete ZTZZC1200 rotary weighing feeder system to a cement plant in Yunnan, China, offering a reliable solution for the metering and continuous conveying of 70 tons of lignite.

Lignite, as an important alternative fuel and energy source in cement production, requires stable and precise feeding to ensure the stable operation of kilns. However, the characteristics of lignite, such as particle size, moisture content, and poor flowability, make traditional feeding systems unreliable.

To address these challenges, the Yunnan cement plant selected Weifang Zhitian's ZTZZC1200 rotary weighing feeder to achieve precise and continuous lignite conveying.

Customer Requirements

The cement plant needed a reliable feeding system capable of continuously conveying lignite from the storage and conveying section to the downstream combustion process.

Key requirements included stable material conveying, accurate weighing, reliable operation, and good adaptability to changes in the moisture and particle characteristics of lignite.

Existing feeding processes suffer from unstable material flow, fluctuating feeding rates, and difficulty in maintaining accurate metering under various operating conditions.

Therefore, the customer needs a complete weighing and feeding solution, not just a simple material conveyor.

Weifang Zhitian Solution：ZTZZC1200 Rotary Weigher

Based on the customer's process conditions and lignite characteristics, Weifang Zhitian designed and provided a complete ZTZZC1200 rotor weighing feeder system.

This system integrates material conveying, continuous weighing, flow control, and quantitative unloading into a compact unit. The rotor structure enables controllable material conveying, while the weighing control system continuously monitors the material flow rate.

The ZTZZC1200 rotor weighing feeder can automatically adjust the feeding rate according to preset process requirements, thereby ensuring a stable supply of lignite to downstream production processes in cement plants.

The complete system provided by Weifang Zhitian includes a rotor weighing feeder, weighing components, drive system, control system, electrical components, a dual-pipe flow stabilization device, and related auxiliary equipment.

Why does lignite require a rotor weighing feeder? ZTZZC1200 Rotary Weigher

Lignite faces numerous challenges in industrial feeding processes because its moisture content, bulk density, particle size, and flowability can change during operation.

Traditional feeders primarily focus on material conveying, while rotary weighing feeders integrate feeding and weighing functions.

The ZTZZC1200 rotary weighing feeder continuously measures the material flow rate and provides real-time feeding information to the control system. The feeding rate can then be adjusted according to setpoints.

This makes rotary weighing feeders particularly suitable for cement plants, as stable fuel feeding is crucial for combustion control and overall process stability.

Stable and Precise Lignite Feeding

During operation, lignite enters the rotary weighing feeder and is continuously conveyed in a controlled feeding process.

The weighing system monitors the actual material flow rate, and the control system compares the measured feeding rate with a preset value. The feeder speed can then be automatically adjusted to compensate for changes in material condition.

This closed-loop control helps reduce feed fluctuations and provides a more stable material supply for the production process.

For the Yunnan cement plant, the ZTZZC1200 rotor weighing feeder provides a practical solution for the continuous metering and feeding of lignite.

Complete Equipment Supply

Weifang Zhitian did not simply provide a single feeder, but rather a complete rotor weighing feeder system.

The complete equipment was configured according to the customer's process requirements and installation conditions.

Main equipment and components include:

ZTZZC1200 Rotor Weighing Feeder

Weighing and Metering System

Drive Transmission System

Feeding and Discharge Components

Electrical Control System

Automatic Feeding Rate Control System

Dual-Pipe Flow Stabilizer

Related Auxiliary Equipment

The integrated equipment configuration simplified project coordination and provided the customer with a complete solution from equipment supply to system commissioning.

Project Benefits

After installation and commissioning, the ZTZZC1200 rotor weighing feeder provides a stable and continuous feed of lignite in the cement production process.

Compared to conventional conveyor feeders, the integrated weighing feeder design allows the system to more effectively monitor and control the actual material flow rate.

The main benefits of the project include:

Stable feeding: Continuous and controllable feeding helps reduce fluctuations in lignite supply.

Accurate metering: The weighing system provides accurate metering.
