The national standard drafted by our company - Technical Requirements for Complete Equipment for Lime Calcination, standard No.: GB/T41,333-2022, was officially issued on March 9, 2022 and officially implemented on October 1, 2022.

1、 Standard drafting unit

The National Standard Plan No. of Technical Requirements for Complete Equipment for Lime Calcination: 20192044-T-609 was proposed by China Building Materials Federation and under the jurisdiction of the National Technical Committee for Standardization of Building Materials and Equipment (SAC/TC465). The main participating units of the standard: Shijiazhuang Fenjin Technology Co., Ltd., Jiangsu Pengfei Group Co., Ltd., Beijing Jiayong Huitong Energy Technology Co., Ltd., Sinoma International Engineering Co., Ltd., Tianjin Cement Industry Design Institute Co., Ltd., Jiangsu Construction Materials Research and Design Institute Co., Ltd., CITIC Heavy Industry Engineering Technology Co., Ltd., Yancheng Institute of Technology Shandong Chenyue Heavy Machinery Co., Ltd., Tangshan Jidong Equipment Engineering Co., Ltd., Guangxi Liugang New Material Technology Co., Ltd., Jiangsu Zhongshengyuan Technology Co., Ltd., Nanjing Kaisheng International Engineering Co., Ltd., Xi'an Xikuang Environmental Protection Technology Co., Ltd., Jiangsu Yongsai Machinery Technology Co., Ltd., Nanjing Henghui Powder Technology Engineering Co., Ltd., Zhuhai Special Economic Zone Shunyi Development Co., Ltd China Building Materials Machinery Industry Association, etc.


2、 Main contents of the standard


This standard mainly specifies the equipment composition, basic parameters, requirements, safety and environmental protection, installation acceptance and commissioning, performance test, delivery documents, etc. of the lime calcination complete equipment.


The technical requirements for complete equipment for lime calcination are applicable to complete equipment for lime rotary kiln calcination and complete equipment for lime shaft kiln calcination. Including double chamber shaft kiln, single chamber shaft kiln, annular sleeve kiln, beam kiln and other equipment.


Among them, in order to highlight technical progress and achieve energy conservation and emission reduction, the beam kiln has written the requirements for the use of adiabatic combustion beams and closed ash dischargers into the national standards.


3、 Impact of standard implementation


1. The implementation of this standard is conducive to reducing the energy consumption of lime production, achieving the standard discharge of lime cleaner production, and improving the position and competitive advantage of domestic lime equipment in the international market.


2. It is conducive to promoting the integration of international production capacity, expanding the influence of the the Belt and Road, promoting the EPC construction of lime projects in countries along the "the Belt and Road", and expanding the export scale of lime calcination complete equipment. 3. It is conducive to standardizing and leading the healthy development of the industry, promoting energy conservation, emission reduction, green development, promoting enterprise transformation and upgrading, improving product quality, and achieving high-quality development.


The release and implementation of new national standards have greatly improved the technology, equipment, resource and energy utilization efficiency, energy conservation and emission reduction, automation level, and economic and technical indicators of China's lime industry, leading the world.
