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 composite vibratory screens. It applies to the metallurgical industry for the dry and wet screening, classification, and dewatering of fine materials. 2. Normative References: In accordance with the provisions of *Guide for Standardization Part 1: Structure and Preparation of Standards* (GB/T 1.1-2009), this standard lists the national and other standards referenced. 3. Terms and Definitions: The term "composite vibratory screen" is defined for the first time in this standard. 4. Product Classification: This standard does not compare with previous relevant standards. It is developed based on the *DZS Type Electromagnetic Vibratory High-Frequency Screen* (MT/T877-2000) standard for the coal industry. 4.1 Type: Based on the characteristics of composite vibratory screens, this standard stipulates that "composite vibratory screens are divided into dry screening and wet screening according to their working modes, and into single-layer, double-layer, or multi-layer sieve surfaces according to their sieve surface structures, and into single-layer or layered sieves according to the number of sieve box layers." Compared with MT/T877-2000, this standard adds multi-layer sieve surfaces to the sieve surface structure. 4.2 Structure: Compared with MT/T877-2000, this standard adds this section, providing a comprehensive description of the main structures of composite vibratory screens, including the sieve box, damper assembly, ore receiving trough, feeding box, frame assembly, funnel, damping springs, control cabinet, and vibrating screen system. 4.3 Model: This standard adopts the relevant provisions of GB/T 25706. It clearly specifies the codes and meanings of various parameters of composite vibratory screens. 4.4 Basic Parameters: This standard
