GB/T 34787-2017 in English

Interpretation of the National Standard of the People's Republic of China GB/T 34787—2017

Background and Significance of the Standard

GB/T 34787—2017 National Standard for Grain and Oil Machinery Drum Concentrator is an important standard formulated under the background of the rapid development of China's grain and oil machinery industry. This standard specifies the terminology, technical requirements and test methods of drum concentrators, filling the gap in the industry's standardization of grain impurity separation equipment.

As a key equipment for grain processing, the performance of drum concentrators directly affects grain quality and yield. The introduction of this standard provides a unified technical basis for the industry to ensure product quality and safety.

Working Principle and Technical Requirements

The drum concentrator uses the rotation of the drum to achieve particle size separation by using the centrifugal force and gravity of the material in the drum. The core lies in the design of the bag hole. Bag holes of different shapes and specifications are suitable for separating impurities such as buckwheat, oats and barley.

Comparison of standard frameworks and analysis of technological evolution

During the formulation of this standard, the development trend of international grain and oil machinery technology was fully considered, and the standard systems of major grain and oil producing countries such as the United States and the European Union were compared and analyzed.

Implementation Suggestions and Precautions

To ensure the efficient operation and safety of the drum separator, users are advised to pay attention to the following matters during purchase and use:

1. Selection: Select the appropriate model according to the type of processed material, and refer to the selection guide in the appendix of GB/T 34787—2017.
2. Maintenance: Regularly check the radial runout of the drive sprocket and screen drum to ensure the stability of the equipment.
3. Safe operation: Follow the safety specifications of GB 5226.1 and GB 10396 to avoid accidents.

Summary

The implementation of GB/T 34787—2017 "Grain and Oil Machinery Drum Selector" will greatly enhance the standardization level of China's grain and oil processing industry and promote the process of agricultural mechanization. It is recommended that relevant companies actively participate in standard promotion activities to ensure technical compliance and product competitiveness.
