GuoNuo Technology Quantitative Feeder: Improving the Batching Process in the Cement Industry

In the production process of the modern cement industry, the batching process of raw material milling and cement milling is crucial for the stability of the quality of the raw materials entering the kiln and the finished cement. The selection of a quantitative feeder plays a significant role in the process conditions, operational control, cost control, product quality, and operating rate of the entire cement plant production process. The quantitative feeder is the most commonly used batching equipment in cement manufacturing. It is an important means to achieve production process automation, ensure product output and quality, reduce energy consumption, and implement comprehensive quality management.

In the cement industry, there are various types of cement, including ordinary cement, slag cement, rapid-hardening cement, and bauxite cement. Cement is produced by mixing materials such as water, sand, and lime in specific proportions, each with different characteristics. Due to the characteristics of the materials and production process requirements, the discharge outlet at the bottom of the silo must be designed with a larger opening size to meet the production requirements for smooth discharge of high-flow and high-viscosity materials. While this large outlet can meet the general discharge needs, it also exerts significant pressure on the conveying equipment during summer, and ordinary belt-type quantitative feeders cannot withstand the dragging requirements under high silo pressure.

To address this issue, an additional feeding device is often installed at the bottom of the silo to drag the material out from the bottom and into an intermediate small hopper. Then, another quantitative feeder is added at the next stage for measurement, and a two-stage equipment interlocking control is used to meet the requirements of quantitative feeding and measurement.

However, this setup requires the quantitative feeder and the feeding device to be installed at different locations, which increases the height requirement for the installation space and raises the costs of equipment investment and silo construction.

The normal working state of a quantitative feeder is high-material-layer and low-speed feeding, which often results in an uneven amount of material in the intermediate hopper of the belt quantitative feeder, leading to material blockage or cutoff and production interruptions. This seriously affects production efficiency and quality. Some companies even need to assign dedicated personnel to address the issue of material blockage and cutoff, significantly increasing labor costs.

Furthermore, in the batching process of the cement industry, precise proportioning is required, and there are requirements for batching accuracy. However, quantitative feeders often experience issues such as belt deviation, which affects batching accuracy.

In response to the above issues in the batching process of the cement industry, GuoNuo Technology's quantitative feeder integrates the pre-feeding device and the belt weighing scale into a single unit, creating a truly integrated high-precision feeder. This not only solves the problem of belt quantitative feeders being unable to withstand high silo pressure but also effectively reduces the construction space and costs for enterprises and avoids the synchronization adjustment issues of belt quantitative feeders.

Additionally, to address the issue of belt slippage, GuoNuo Technology's quantitative feeder can be equipped with an automatic tensioning device, effectively preventing belt slippage and improving batching accuracy. The feeder's instrument can perform fault self-diagnosis and power-off data protection functions, making daily measurement more efficient for customers and increasing the feeder's operational stability.

GuoNuo Technology's quantitative feeder has always been developed based on customers' actual needs and on-site issues, continuously undergoing technological innovation to meet various on-site usage requirements. It is widely used in the cement industry, greatly improving the cement batching process, enhancing batching efficiency, reducing labor input, and lowering enterprise costs.
