Abstract
The non-powered separator is one of the key equipment in the dry sand production line, which is responsible for the separation of coarse and fine materials. In this paper, based on the turbulence Standard Model, the air sand powder three-phase fluid model is simplified to gas-solid-solid three-phase flow, and the 3D model of the non-powered separator was built. The process of sand powder separation was simulated by using Fluent software. It is found that the larger the air volume control valve blade angle is, the more sand is removed, and the blade angle can be adjusted in the range of 15° to 60° according to the actual needs in industrial production.
