Dewatering Screen

McLanahan Dewatering Screens

Over 30 years ago, McLanahan Corporation was the first to introduce Dewatering Screens to the mining industry, where the screens quickly became the standard.

McLanahan Dewatering Screens feature custom engineered, heavy duty screen media for the high capacity applications encountered in today’s production conscious market. Side frames and beams are Huck bolted together, not welded, so individual components can be replaced. They also have a combination of standard, high quality wear resistant side wear linings, optional deck dividers, and dams. Performance flexibility is enhanced by variations in screen media and the use of deck dividers. McLanahan Dewatering Screens have the highest capacities available in the industry and can process up to 400 tph of coarse sand on a single machine. Available sizes are 3′ x 8′, 4′ x 10′, 5′ x 12′, 6′ x 12′, 7′ x 12′, and 7′ x 16′.

By applying our worldwide industry experience and just the right combination of frequency and amplitude, McLanahan Dewatering Screens provide drip-free discharge for applications that range from primary sand products to ultra fines recovery. The resulting improvements in housekeeping and immediate availability of products mean bottom line benefits!

Filter Presses:

McLanahan Plate & Frame Filter Press Engineered by Tongiani

McLanahan’s Plate & Frame Filter Press has revolutionized fines dewatering with the most efficient, cost effective technology in the industry.

The Patented Hydro-Pneumatic Cushion System applies uniform pressure to the entire plate ensuring a leak-free plate seal.  With pressures of 290, 580 and 870 psi, the press can dewater even the most difficult sludge, including those with a high clay content. The PLC controlled press can be built for varying chamber thicknesses to produce the driest cake for each specific slurry with moisture contents down to 15%.

Features of the Patented Plate & Frame Filter Press:

• No Need For An Operator To Monitor Feed Density, Flocculant Dosage Or Belt Conditions

• Electric Screw Drive Design Eliminates Hydraulics And Associated Mess

• Overhead Beam Design Allows Maximum Access For Plate And Screen Maintenance

• Patented Hydro-Pneumatic Sealing Provides A Uniform Seal Resulting In Longer Cloth And Plate Life

• Plates Open And Close Faster For Shorter Cycles

• One Unit Provides Capacities Of 5.5 To 88.0 STPH

• Increased Water Recovery

• Produces Drier Fines

Log Washers

McLanahan Mudmaster and Super Mudmaster Log Washers

In 1890, Samual McLanahan, 2^nd Generation, conceived an idea to wash clay from the rock in his Florida phosphate deposits. Inside a long box, he mounted wooden logs and attached cast iron paddles to them. On January 27, 1891, he secured a patent for his new machine and called it the Log Washer. From that day on, McLanahan employees have continually updated his design to include the most modern technology and design features available.

Log Washers are designed to remove tough plastic clay, soft rock or other friable waste. Using renewable, abrasion resistant paddles affixed to a twin shaft design ensures that an aggressive washing action breaks down even the toughest clay.

Log Washers can effectively remove up to roughly 15% clay and deleterious materials in the feed.

Used around the world for washing gravel, cemented aggregates, limestone, phosphate and various ores, McLanahan Log Washers have set the standard by which all others are measured. These high quality, highly durable machines perform well under the toughest clay conditions with minimum power, water and downtime.

Coarse Materials Washers

McLanahan Coarse Material Screw Washers

Coarse Material Screw Washers are used primarily to process crushed stone and gravel that generally range from 3/8″ to 4″. They effectively remove light, loamy-type clays, dirt, crusher dust and coatings that cannot be removed by wet screening alone.

The selection of a Coarse Material Screw Washer (CMSW) is based upon the type of material, desired capacity and maximum feed size. A CMSW can be

furnished with our standard 20 paddles, 40 paddles or ALL paddles. More paddles provide a greater washing action, but at a reduced capacity.
