Final powder grinding double-fan system for raw material roller press and rolling method

Abstract

The invention discloses a final powder grinding double-fan system for a raw material roller press. The system comprises a kiln tail high-temperature fan and a kiln tail exhaust fan. An air outlet of the kiln tail high-temperature fan is connected with an air inlet of a V-shaped powder selecting machine and an air inlet of a kiln tail bag dust collector. An air outlet of the V-shaped powder selecting machine is connected with an air inlet of a dynamic powder selecting machine. An air outlet of the dynamic powder selecting machine is connected with the air inlet of the kiln tail bag dust collector. An air outlet of the kiln tail bag dust collector is connected with an air inlet of the kiln tail exhaust fan. An air outlet of the kiln tail exhaust fan is connected with the air inlet of the V-shaped powder selecting machine and a kiln tail chimney. The invention further provides a rolling method based on the system. By the adoption of the final powder grinding double-fan system and the rolling method, a circulating fan of a powder grinding system in a traditional system is omitted, the flow is simplified, the system resistance is reduced, the equipment fault point is reduced, the capital construction investment can be effectively reduced, the power consumption of the system is reduced, and the maintenance workload of equipment is reduced.

Description

technical field [0001] The invention relates to the field of rolling machinery, in particular to a double fan system for final grinding of a raw material rolling machine and a rolling method. Background technique [0002] At present, the final grinding system of the raw meal roller press is a relatively mature grinding process generally adopted by domestic cement production enterprises. The waste gas treatment system for the final grinding of the raw meal roller press in related technologies is usually a three-fan system (high temperature fan, Grinding system circulating fan, kiln tail exhaust fan), its main feature is that the grinding system uses relatively independent air, and the grinding system has specially set up a grinding system circulating fan, between the raw material grinding and the waste gas treatment system in operation The interference is small; but the process flow of the system is relatively complex, the floor area is large, the project investment is high, ...

[0002] At present, the final grinding system of the raw meal roller press is a relatively mature grinding process generally adopted by domestic cement production enterprises. The waste gas treatment system for the final grinding of the raw meal roller press in related technologies is usually a three-fan system (high temperature fan, Grinding system circulating fan, kiln tail exhaust fan), its main feature is that the grinding system is relatively independent in wind use, and the grinding system has specially set up a grinding system circulating fan, between the raw material grinding and the waste gas treatment system in operation The interference is small; but the process flow of the system is relatively complex, the floor area is large, the project investment is high, the number of process equipment is large (many failure points), and the circulating fan of the grinding system operates in a high-dust environment with dust accumulation and wear on the blades , vibration and other issues
