For the technical transformation of the completed production line, Sinoma International has said that with the transformation of the cement industry into “high-end, green and intelligent” and the upgrading and concentration of the industry quality, the demand for equipment-centered technical transformation, digitalization and operation and maintenance is huge.

There is a large market space for technical transformation of the old lines.

The details are as follows: List of annual technical transformation projects of major brand factories in East China: 1.

Environmental protection technical transformation projects involve low pressure dust collection and environmental protection transformation, precise SNCR denitration, denitration system upgrading and transformation, unorganized ultra-low emission transformation, high energy consumption motor elimination, grinding system technical transformation, alternative fuel technical transformation, green mine construction, and yard dust reduction, crusher dust treatment, dust treatment, recycling of circulating water, desulfurization transformation, chlorine water tank demolition and construction, dosing belt dust treatment, hoist transformation, V-type air cooler transformation The belt gallery is fully closed, the grate cooler is soundproof and noise-reducing, the greenhouse is renovated, the ground is hardened, the flue gas online monitoring system, the raw coal and coal homogenization shed fog and dust reduction system, the mine water intake spray project, the mine ecological restoration and treatment project, etc.

There are relatively few technological transformation projects in the southwest, including 50 improvement projects, 25 safety projects and 17 environmental protection projects.

From the current domestic situation, there are about 1600 cement clinker production lines in operation in China, of which more than 1400 have been in operation for more than 10 years.

From the above 270 technical transformation projects, we can see that there are 79 environmental protection projects, 52 safety projects, and 49 improvement and upgrading projects in East China.
