Drum stone screening machine

During the entire application process, the drum stone screening machine equipment runs slowly and evenly, with little impact vibration, stable operation, and convenient installation and operation. It can be immediately placed on a leveled road surface or concrete floor and under a hopper.

The drum stone screening machine can be immediately placed on a leveled road surface or concrete floor, as well as under a hopper. The double-layer shaftless drum stone screening machine can be equipped with a comb shaped cleaning organization. During the entire screening process, the actual effect of uninterrupted cleaning of the screen body can be achieved based on the relative speed of the comb shaped cleaning organization and the screening cylinder. This ensures that the double-layer shaftless drum stone screening machine remains clean, non sticky, non blocking, and does not harm the actual screening effect throughout the entire process. According to different grade classification regulations, the grade classification of the double-layer shaftless drum stone screener is generally 1-4 sections from fine to coarse, and the raw materials are screened from the first section to the final section of stainless steel screen from fine to coarse, and the raw materials beyond the final section of stainless steel screen holes are discharged from the feed inlet. The main project of the vibrating screen is the screening cylinder. The double-layer shaftless drum stone screening machine is composed of multiple circular shaped stainless steel screens, which are generally inclined to the ground plan. The external environment is sealed by a sealed isolation cover to avoid environmental pollution.

The double-layer shaftless drum stone screening machine equipment is convenient for closed dust removal, with small maintenance volume, simple maintenance, and long service life. It is often used in the classification of refractory insulation materials, coal, river sand, sand and stone.

Principle of drum sand and stone screening machine

Principle: The roller sand and stone screening machine is divided into five parts: hexagonal drum, sound card rack, Büchner funnel, reducer and motor. After the crushed sandstone is fed into the drum, on the one hand, it is selected along with the rotation of the drum. On the other hand, the drum sandstone screener has the fluidity of sandstone with large particle size distribution along the inclination of the drum, and is slowly screened according to the stainless steel screen with different meshes. Small sand and gravel materials fall into the respective Büchner funnel after screening, and then are transported manually or automatically out to the finished product stack.
