Screen, be divided into two diameter ranges, improve screening precision, realize once-through operation and granule materials are divided at least three diameters
Scope, gradation high precision, structure is simple, easily manufactured, occupies little space.
Improved, described screen box is provided with least two, and the second discharging opening of a upper screen box enters with next screen box
Material mouth corresponds to.To the second discharging opening of a upper screen box, granule materials out are further screened next screen box, improve
The effectiveness of classification of granule materials.
Improved, in next screen box, the aperture of the first sieve aperture is less than the aperture of the first sieve aperture in a upper screen box, next
In screen box, the aperture of the second sieve aperture is more than the aperture of the 3rd sieve aperture in a upper screen box, the hole of the 3rd sieve aperture in next screen box
Footpath is more than the aperture of the 3rd sieve aperture in a upper screen box.Next screen box granule out to the second discharging opening of a upper screen box
Material is further screened, and improves the effectiveness of classification of granule materials.
Improved, in a screen box, the aperture of the 3rd sieve aperture and the aperture of the second sieve aperture are equal, described 3rd discharging opening
It is set to a discharging opening with the 4th discharging opening.Realize once-through operation and granule materials are divided into three diameter ranges, gradation essence
Degree is high, and structure is simple, easily manufactured, occupies little space.
Improved, described screen box is connected with spring vibration device.Make the screening efficiency of screening plant high.
Beneficial effect:
After technique scheme, a kind of this invention castable screening plant, granule materials are divided into big-and-middle by upper sieve plate
Little three diameter ranges, lower sieve plate further screens to the granule materials of intermediate diameter range, is divided into two diameters
Scope, improves screening precision, realizes once-through operation and granule materials are divided at least three diameter ranges, gradation high precision,
Structure is simple, easily manufactured, occupies little space.
