Intelligent Evaluation Method for Heavy Medium Separation Systems in Coal Preparation Plants

1 Scope

This document specifies the intelligent evaluation index system and scoring index for the heavy media separation system in coal preparation plants. This document applies to the intelligent evaluation of a single heavy media separation system in a coal preparation plant.

2 Normative references

This document has no normative references.

3 Terms and Definitions

This document does not contain any terms or definitions that need to be defined.

4.1 Composition of the Indicator System

4.1.1 The intelligent indicator system of the heavy medium separation system in the coal preparation plant consists of essential indicators and scoring indicators.

4.1.2 Essential indicators are the prerequisite for evaluation. Only when all essential indicators are met can the evaluation proceed to the scoring indicators.

4.1.3 The scoring index is the core of the evaluation. It quantifies the intelligence level of the heavy media sorting system and measures its degree of intelligence. High and low.

4.2 Essential Indicators

4.2.1 The network bandwidth should be sufficient to meet the needs of subsequent large data transmission, and the backbone network transmission rate should not be less than 1,000 Mbit/s.

4.2.2 The data format and interface should meet the communication and data sharing requirements with other systems in the coal preparation plant.

4.2.3 The main production process equipment is subject to remote or centralized interlocking control, and the main production links have complete quality measurement and safety monitoring systems. The system is efficient, with complete and accurate monitoring facilities for key coal preparation process parameters.

4.2.4 All equipment, facilities, and instruments in the sorting system are safe and reliable, and can operate continuously, stably, and effectively for 4 hours without human intervention. above.

4.3 Scoring Indicators The intelligent scoring index system for heavy media separation systems in coal preparation plants includes primary, secondary, and tertiary indicators. Primary indicators reflect... The overall requirements and construction content of an intelligent heavy media separation system for coal preparation plants include. monitoring and control execution, intelligent production control, and intelligent decision-making. The strategy. Secondary indicators are general indicators under the primary indicators, totaling

8.Tertiary indicators are specific, actionable, and measurable indicators under the secondary indicators. The evaluation criteria consist of 29 items. Table 1 shows the scoring index system for the intelligent coal preparation plant sorting system.
