Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part

1.Structure and drafting rules for standardization documents" Drafting is required. This document is part 3 of GB/T 35150 "Technical requirements for complete sets of equipment for the production of new dry process cement". GB/T 35150 has been issued The following parts were published. Part

1 Scope

GB/T 35150.3-2024 is the cement preparation part of the Chinese standard for complete dry process cement production equipment, covering the finish grinding system that turns clinker into cement. It is the largest single electricity consumer in the plant, typically a third of the works total, which is why the choice between ball mill, vertical roller mill and roller press with separator, and the efficiency of the separator itself, dominate the specification. The standard sets the classification and composition of the cement preparation system and then the technical requirements: the grinding equipment and its capacity, specific energy consumption and product fineness and particle size distribution, the separator and its efficiency, the feeding, conveying and blending equipment, the additive dosing, the dedusting and the noise, the drive and the instrumentation and control, and the safety, availability and reliability requirements. It then gives the test methods and the inspection rules. It took effect on 23 August 2024.

The new dry process cement production technology is based on the suspension preheating and pre-decomposition technology, which uses the existing technologies in thermal engineering, powder engineering, fluid mechanics, etc. The comprehensive technology of cement production adopts modern scientific theories and technologies, and uses computers and network information technology. The complete set of equipment consists of relatively independent The independent process system equipment mainly includes raw material crushing and homogenization, raw material preparation, fuel preparation, cement kiln co-processing, clinker burning, Cement preparation, dust removal, desulfurization, denitrification, process control, packaging and shipping system equipment. At present, my country's cement equipment and technology have reached the international advanced level, but the complete set of equipment based on system solutions is facing With the expansion of domestic cement equipment exports and engineering general contracting, the systematic support of complete sets of equipment is urgently needed. The demand for standards is also gradually increasing. The purpose of formulating the standards for new dry process cement complete sets of equipment is to improve the user-oriented cement complete sets of equipment standards. The system provides technical support for the high-quality development of the cement industry, better guides the industry to develop in the direction of green, low-carbon, and intelligent manufacturing, and supports Support the export of complete sets of cement equipment in my country. This document is used to guide the process selection and design of complete sets of equipment for cement preparation system, energy consumption testing and pollution emission control, and standardizes water Technical requirements for installation acceptance, performance commissioning, etc. of complete sets of equipment for mud preparation systems, and promote and implement energy-saving and carbon-reducing technology and equipment in the cement industry industrial application and transformation and upgrading, and coordinate with other series of standards.
