Scope

Main Technical Content: 1. Scope: This standard specifies the product classification, technical requirements, testing methods, inspection rules, marking, labeling, user manuals, packaging, transportation, and storage of laminated high-frequency fine screens, applicable to the metallurgical industry for dry and wet screening, grading, and dewatering of various fine materials. 2. Normative Reference Documents: In accordance with the provisions of *Guidelines for Standardization Part 1: Structure and Preparation of Standards* (GB/T 1.1-2009), this standard cites national and other standards that it references. 3. Terms and Definitions: The standard defines the following terms and definitions: - **Laminated high-frequency fine screen**: - **Lamination**: - **Resonance composite linear vibration**: - These terms ("laminated high-frequency fine screen," "lamination," and "resonance composite linear vibration") are introduced for the first time. 4. Product Classification: - There are no previous corresponding standards for comparison, so the following content is newly established. - 4.1 Type: Laminated high-frequency fine screens are divided into two types based on vibration mode: linear vibration (ZG) and resonance composite linear vibration (FGG). - 4.2 Structure: A comprehensive description of the main structures of laminated high-frequency fine screens is provided, including the screen box assembly, frame assembly, material receiving trays above and below the screen, rear support frame, feeding box, water spraying device, wiring device, and control cabinet. The vibration motor is installed in the screen box assembly. - 4.3 Model: The standard adopts the provisions of GB/T 25706 to clearly define the codes and meanings of various parameters of laminated high-frequency fine screens. - 4.4 Basic Parameters: All models of laminated high-frequency fine screens must meet the requirements specified in the table, including s
