Cedarapids has new options for the MHS6203 and MHS8203 screen modules, including a wash plant option and a feed box and support structure. The screen modules feature the TSV Series horizontal screens, combining the El-Jay oval-stroke action and a large blending chute for a range of discharge options. The new wash plant option includes a feed box with two spray bars and support structure, a screen spray system with manifold, and an under-screen flume. Outfitted as a wash plant, the module can produce washed stone products and be paired with a sand screw or other sand processing and fines recovery equipment.

The Eagle Trek line of portable wash equipment from EIW (Eagle Iron Works) includes familiar solutions and equipment designed into a standard array of sizes. The Eagle Trek TSP, for example, features an EIW classifying tank over the top of a double screw washer. Combined with an Eagle double screw fine material washer, EIW says two typical construction-grade sand-specification products can be made simultaneously. Additionally, the Eagle Trek SSP (pictured) contains a horizontal screen and a double screw washer. The plant includes a triple-shaft horizontal vibrating triple-deck screen, which can size washed rock products for direct stockpiling.

The portable Spirit wash plant is capable of producing as many as five products, according to Superior Industries. The plant carries a 6-ft. x 20-ft. Guardian horizontal screen, plus a sand production module and ultra-fines recovery module. Material is fed to a slurry box, which liquifies it to improve the screening and stratification processes. The three-deck horizontal screen washes and sizes three products from a top, middle or bottom deck. Leftover sand is then processed through one of two Spirit wash modules. These modules consist of one or more Helix cyclones followed by a dewatering screen. The first wash module uses a cyclone to size and separate material for a traditional sand product. A dewatering screen ensures it’s instantly saleable off the discharge chute. Depending on the deposit, an optional ultra-fines recovery module washes out minus 100 to minus 400 fines for microfine material.

Quick-startup opportunity with plug-and-play plant

CDE designed and built the Combo all-in-one wet processing plant on one chassis. CDE engineers can fully assemble and test the plant before it’s dispatched. Once factory acceptance testing is completed, the Combo is deconstructed for transport. During this process, CDE splits the plant into several large shipments to ensure rapid reassembly when delivered on site. The Combo arrives on site ready to plug and play – either as a standalone plant or as part of a larger turnkey solution. This enables producers to start processing material within days for faster return on investment, CDE says.

The FM UltraFines recovery unit from Terex Washing Systems allows users to recover ultra-fines material from wastewater streams in an efficient manner, the company says. Users can process up to 450 cu. meters per hour of slurry, recovering material as low as 40 micron. This, in turn, reduces the volume of solids sent to storage ponds or water treatment plants. The FM UltraFines unit includes a centrifugal pump, a hydrocyclone cluster and a high-frequency dewatering screen – all on one chassis, which features a conical tank and an anti-turbulence system, as well.

Hydrocyclone introduces step change in performance, sustainability

The Cavex 2 marks what Weir Minerals calls a new generation of hydrocyclones. According to Weir, its Cavex 1 design set an industry benchmark over two decades ago with a 360-degree laminar spiral inlet geometry, which significantly reduced turbulence. Weir improved upon the design with the creation of LIG+ inlet and chamber design. The LIG+ design enables Cavex 2 hydrocyclones to classify up to 30 percent more feed slurry, Weir says, while occupying the same footprint as other hydrocyclones. Also, the new design took into consideration the shape and angle of the hydrocyclone to ensure particles report to the correct stream.
