Classifying Aggregates with the Right Screening Equipment

Construction and other similar industries often utilise aggregates as part of their daily operations. Since these industries require a precise set of materials, the aggregates that they receive must also contain the needed specifications of a given work or activity.

Given the strict requirements of these industries, the aggregates must be screened correctly. Aggregates, which are mostly comprised of grained particles, are often screened to remove unnecessary particles. The screening process of aggregates can likewise help in producing the needed products. It can likewise help split the feed stream between separate processing lines, with other products being processed independently for faster operations.

Aggregates can be classified into different categories like grain size, density, and shape. These classifications, however, can only be achieved with the right screening equipment. Here are some factors that you should consider when choosing the best equipment for the screening process.

Bed Depth

The quality of the screening process can be dictated and affected by the bed depth of the screening equipment. This specific factor describes the depth of the material on the screen, which can directly determine the sorting quality of the equipment. The bed depth of the equipment can also determine the quantity of fines that can pass through the deck.

Feed Rate

Another factor to consider when choosing the best equipment for screening is its feed rate. For a piece of screening equipment to be reliable, it must maintain regular and consistent feed throughout its operations. High-quality aggregates can only be obtained with screening equipment that has an excellent feed rate. A piece of equipment with an irregular feed rate, alternatively, may only result in the inclusion of oversize materials on the aggregates as the screen load runs at its minimum. Fine materials may likewise be carried over once the screen load of the equipment runs at its maximum.

Openings

One more crucial factor that you should consider when picking the best screening equipment for you is its screen openings. The screening mesh of equipment clings on the concept of nominal size and effective size. Nominal size pertains to the true diameter of the screen opening on the deck. Effective size, on the other hand, refers to the size of the product that the screening mesh will produce. In choosing your screening mesh, make sure that its nominal size will be smaller compared to your preferred effective product size. As for the design of the mesh openings, you may want to increase the space between their holes, webbing, or wire diameter so that the screening equipment can obtain increased feed capacity.
