The relevant person in charge of the Ministry of Industry and Information Technology recently revealed that as China's industrialization process is gradually accelerating, the amount of industrial solid waste discharge is increasing year by year. To promote the comprehensive utilization of bulk industrial solid waste, the Ministry of Industry and Information Technology presided over the preparation of the "12th Five-Year Plan for the Comprehensive Utilization of Bulk Industrial Solid Wastes," which has been approved and is expected to be released soon.
It is reported that according to the "planning", the comprehensive utilization rate of industrial solid waste in China will reach 72% from 2010 to 2015. To achieve this goal, regional pilots will become one of the key tasks for steadily promoting the comprehensive utilization of industrial solid waste. This largely means that the government has put the comprehensive utilization of solid waste on the agenda, and the use of waste gas resources such as carbide slag, steel slag, and coal gangue will also receive attention.
Although many cement companies have already crushed waste slag such as calcium carbide slag, steel slag, coal gangue and other materials as mixed materials into cement, the intensity has not been sufficient, and the relevant crushing equipment manufacturers have not attracted attention. The research and development productivity is not enough. Currently, domestic equipment such as desulphurization limestone crusher, carbide crusher, calcium carbide crusher, coal gangue crusher, steel crusher, etc., can be broken by ordinary crushing equipment, but it has no special effect. Material fineness and production efficiency are not high.
After visiting dozens of cement production enterprises, the author learned that at present there are not many enterprises that are aware of the importance of recycling of waste slag resources. There are even fewer companies that can produce specialized equipment, and they have many years of research in the cement industry. Lu Hongbo, chairman of Zhengzhou Dingsheng Engineering Technology Co., Ltd., is a special case of cement crushing equipment.
As early as the beginning of 2011, Lu Hongbo took the lead in proposing forward-looking perspectives for cement companies to enter the gravel industry, which was deeply recognized by the cement industry. Recently, large domestic leading cement companies have entered the gravel aggregate industry, confirming the correctness of his assertions. He is far-sighted for special equipment such as calcium carbide slag, dry mortar, desulfurized limestone and other solid wastes as well as construction waste disposal. Zhengzhou's heyday not only produces China's largest single-stage hammer crusher, large-scale counterattack, and jaw crusher. Machines and other commonly used equipment, production equipment, calcium carbide slag crusher, desulfurized limestone crusher, construction waste disposal equipment and other special crushing equipment.
The cement industry is not prosperous in the busy season and faces the passive situation of mergers and reorganizations. The relevant crushing equipment market has long been saturated. The Ministry of Industry and Information Technology (MIIT) plans for the comprehensive utilization of solid wastes have guided the crushing equipment manufacturers to increase the construction waste disposal equipment and waste slag resources. With the emphasis on special equipment and other policies, the policy has been blowing and when it is time to sail, crushing equipment manufacturers must decide as soon as possible.
