Screening/Sizing
Screening equipment is needed to size and separate materials during production. Screens placed before a primary crusher remove fine materials like abrasive stone or sand, reducing wear on crusher liners and unnecessary power consumption.
After Primary crushing, multi-deck screens sort materials into different sizes for further crushing in secondary and tertiary stages. This may alleviate the load on crushers and processing equipment by eliminating undersized and oversized materials.
In addition to preparing material for further crushing, screens are used in other processing stages to produce final products and dewater washed material to below 14% moisture for easier handling.

Screening involves vibrating or tumbling actions that separate feed material by size, with smaller particles passing through screen media panels while larger particles remain on top. This creates multiple material fractions.
Each application has unique screening requirements, but all rely on screen media for effective separation. Common screen media includes woven wire cloth, urethane, rubber, or combinations, offering varying capacity and efficiency levels.
Effective screening reduces fines generation, minimizes crusher size, splits feed streams for separate processing, and removes refuse material, ultimately improving the efficiency of the processing plant and a quick return on investment.
McLanahan’s Screening/Sizing Solutions by Suprabakti
Screening equipment plays a role in a mineral processing plant. It is capable of having a significant impact on both the product’s quality and the capacity of a plant. Screening equipment can be stationary or portable, with a simple setup and breakdown for effortless transport between locations.
When choosing screening equipment, consider the material’s shape and size, the screen media openings, the amount of material already at the desired size, the presence of harmful materials, the need for water, and other factors.
Suprabakti supplies Screening products from McLanahan, which offers a range of screening solutions for both wet and dry applications, fitted to industry needs. McLanahan’s screening options include vibratory screens and screening feeders, ensuring producers have the right tools for their specific applications.
Vibratory Screens
McLanahan Vibratory Screens utilize screen decks covered in various-sized openings to separate material through vibration. Smaller particles fall through the openings, while larger ones remain on the top of the screen deck.
Vibratory Screens Products
- MD Vibratory Screens are compact, high-capacity units that screen more tons per hour per square foot than conventional screens, all while taking up the same or less floor space.
- Rotary Trommel size and separate feed materials in various industries like municipal waste, recycling, industrial, aggregate, and mining.
- Vibratory screens use decks with varying sizes of openings to separate materials by vibrating them.
Screening/Sizing Feeders
McLanahan’s Feeders offer screening and sizing functions alongside material flow control for diverse equipment. With the ability to scalp fines and eliminate undersized material, these feeders are made to reduce crusher wear.
Screening/Sizing Feeders Products
- Vibrating Grizzly Feeders combine feeding and scalping functions in a single unit, cutting costs by eliminating the need for two separate units.
- Wobbler Feeders use rotating elliptical bars on the deck to control material feeding and fines scalping.
