Abstract

The aspiration pipe of cement mills was previously viewed by the industrial enterprises of building materials primarily as a process of reducing the emission of dust from the loading space in the neck of the mill shop and reduce airborne dust in the grinding part. The works of different authors have shown that the efficient mode of aspiration intensifies the mill work and the right choice of aspiration, the de-dusting units reduces the return of the discharged dust. These studies have not been completed yet. In this paper we will consider the analytical form of the expressions determines the resultant velocity components and the aspiration flow in the first chamber of the tube mill rotated with the drum mill. It was established that the helical pitch of the aspiration flow in the chamber is inversely proportional to the volumetric flow rate of the air mass and directly proportional to the speed of the drum. The grinding bodies decrease the oscillation amplitude of masses aspiration by the increasing of the load factor of camera. The analytical dependences allow defining the rational modes of aspiration and required air flow.
