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 linear vibrating screens. It is applicable to material screening and grading, as well as dewatering in the metallurgical industry, and can also be used for bulk materials such as ores. 2. Normative Reference Documents In accordance with the provisions of *Guide for Standardization Part 1: Structure and Preparation of Standards* (GB/T 1.1-2009), this standard cites national and other standards that are referenced. 3. Terms and Definitions The term "LM-type linear vibrating screen" is defined for the first time in this standard. 4. Product Classification 4.1 Type Linear vibrating screens are classified by their application (grading, dewatering, or desanding), by the structure of the sieve surface (folded, straight, or multi-inclined), and by the number of sieve layers (single or double). Compared with JBT6389, JBT7891, JBT7892, and JBT10653, this industry standard adds the folded sieve surface structure to the sieve surface types. 4.2 Structure A comprehensive description of the main structures of linear vibrating screens is provided. Compared with JBT6389, JBT7891, JBT7892, and JBT10653, the scope of coverage is more comprehensive, including vibration motor-excited linear vibrating screens, multi-inclined sieve surfaces, and large-scale linear vibrating screens (also known as banana screens). 4.3 Model The relevant provisions of GB/T 25706 are adopted to clearly define the codes and meanings of various parameters of linear vibrating screens. 4.4 Basic Parameters The basic parameters of all linear vibrating screen models shall meet the requirements specified in the table, including sieve surface dimensions (width and length), sieve layer numbers, operating frequency, amplitude, feed particle size, sieve surface inclination,
