The capacity of a rotary screen typically ranges from 5 TPH to 20 TPH, depending on the screen's dimensions.
Rotary screens are used for separating materials based on size. Their capacity is influenced by several factors, primarily the diameter and length of the screen. Larger screens, naturally, handle more material. The following provides more detail about what impacts rotary screen capacity:
-
Screen Dimensions: As noted, diameter and length are key. Screens can range significantly in size. For instance, examples include 1.5m diameter x 5.0m long screens and 2.4m diameter x 20m long screens.
-
Material Type: The type of material being screened plays a significant role. Materials that flow easily will have higher throughput. Materials that tend to clump or stick will reduce capacity.
-
Screen Mesh Size/Hole Size: The size of the openings in the screen also impacts capacity. Smaller openings restrict flow more than larger openings. The reference mentions up to 300,000 holes in a single screen, highlighting the variability in mesh.
-
Rotation Speed: The speed at which the screen rotates affects how quickly material is processed.
-
Feed Rate: The rate at which material is fed into the screen must be carefully controlled. Overfeeding can reduce efficiency and capacity.
-
Moisture Content: Moisture content in the feed material is a critical factor, because wet material will stick to the screens, reducing throughput.
Therefore, while a general range of 5 TPH to 20 TPH exists, the specific capacity of a rotary screen is highly dependent on these operational and design factors.
