Vibratory Replacement Aggregate Screens for

2021-7-28  Our non-blinding aggregate screens are high quality screening surfaces that help to minimize pegging and blinding while still separating flakes and splinters. These screens provide accurate screening and sizing where other products fail, due to high percentages of open area when compared to square openings, resulting in higher throughput.

Coarse Aggregate Gradation: What Works Best?

Testing Screens and Test-Master units are designed primarily for particle sizes from 4in to No. 4 (100mm to 4.75mm). By adjusting agitation times, they can provide reliable results for sizes down to 75µm (No.200). Models are available to hold from five to seven screen trays with a clear screen area of 14.75x22.75in (375x578mm).

Vibratory Screens. Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification.
