Grinding machine circulating air adjusting device

Abstract

The invention discloses a grinding machine circulating air adjusting device. The grinding machine circulating air adjusting device comprises a grinding roller machine (1), a feeding pipe (2), an exhaust pipe (3), an exhaust fan (4) and a discharging pipe (5), wherein the feeding pipe (2), the exhaust pipe (3), the exhaust fan (4) and the discharging pipe (5) are installed on the grinding roller machine (1); one end of the exhaust pipe (3) communicates with the grinding roller machine (1), and the other end of the exhaust pipe (3) communicates with the exhaust fan (4); the discharging pipe (5) communicates with the exhaust fan (4), an air return pipe (6) is connected to the exhaust fan (4), and the other end of the air return pipe (6) communicates with an inner cavity of the grinding roller machine (1); and ventilating holes (7) are formed in the ends of the air return pipe (6). The grinding machine circulating air adjusting device has the beneficial effects that the grinding machine circulating air adjusting device has the advantages that the structure is simple, heat preservation and pressure preservation are achieved, grinding roller efficiency is high, and the power grinding quality is high.

Description

technical field [0001] The invention relates to the technical field of powder graded conveying, in particular to a mill circulating air regulating device. Background technique [0002] When the roller grinding machine is working, the temperature is generated inside the roller grinding machine through the extrusion of the material layer, and the temperature rises as the grinding roller continues. When the temperature is not controlled, the material layer is unstable, thus As a result, the load on the grinding roller is large and the grinding quality is poor. The high-temperature airflow in the grinding roller is sucked away by the exhaust fan, and the internal pressure of the grinding roller machine cannot be stabilized. , and cannot achieve rapid heating. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a mill circulating air regulating device with simple structure, heat preservation and ...
