roller sand screen machine
Overview
Except for the finished material stacking belt conveyor, all systems are integrated into an overall framework, which not only ensures the integrity of the equipment, but also leaves appropriate maintenance and inspection space. The high degree of integrity is convenient for storage or transportation on the construction site, which is convenient and safe. The core screening system of
adopts the mixing principle of mixer. The raw materials are rolled, pushed and squeezed by continuous spiral blades in the mixing drum and the friction between materials, which has strong natural effect and high reliability. The rolling screen cylinder is placed flat to ensure that the material flow is rolled and screened more than four times between the spiral blades of the screen cylinder, so that the sand material is repeatedly rolled and fully dispersed and screened. It is different from the phenomenon of incomplete screening and mixing caused by the mutual impact of large and small materials caused by inclined rolling screen or inclined vibrating screen.
use
drum screening machine is easy to close dust collection, small maintenance, simple maintenance and long service life. It is a frequently used equipment in refractory materials, coal, river sand classification and sand and gravel block classification.
Principle
Drum Screen is composed of five parts: hexagonal drum, frame, funnel, reducer and motor. After the broken stone enters the drum, on the one hand, it is screened with the rotation of the drum. On the other hand, the stone with large particle size flows forward along the slope of the drum and is gradually screened out through the screens of different mesh. Small stones are sieved out and fall into their respective funnels, and then transported out manually or by self-flow to the finished product pile.
