TWIN-SHAFT MIXER With the addition of a small model, capacities for the company’s twin shaft mixers now range from 54 cu. ft. to 318 cu. ft. Each model
With the addition of a small model, capacities for the company’s twin shaft mixers now range from 54 cu. ft. to 318 cu. ft. Each model comes with a countercurrent mixing design that product developers note achieves 100 percent mixing coverage in as little as 60 seconds, providing uniform material distribution and a stronger end product. The twin shaft models use a two-stage gear reducer for more efficient operation, as compared to three-stage reducers. Cast for long life, the paddles, end scrapers and liners are designed also for fast adjustment and replacement.
Standard equipment on the twin-shaft mixers includes a self-diagnostic system, which monitors oil and motor temperatures, as well as fluid levels in the hydraulic system and gear case. If any measurements deviate from the normal operating range, an automatic warning is relayed. Also included is a hydraulic adjustable discharge door for full or partial discharge. Pneumatic operation and an automatic washing system are optional. The twin-shaft mixers are backed with a five-year drive train warranty. Mixer Systems

EcoLine Bearing, Chain & Roller Lubricant Û a bio-based, rust-preventative product derived from American-grown soybeans Û is said by the manufacturer to offer lubrication superior to most conventional formulas. A sustainable product, it contains 86 percent less petroleum than traditional lubricants, the company notes, without sacrificing performance or changing metal surface properties. EcoLine’s content has been subjected to rigorous testing at Iowa State University as part of EPA’s Federal Bio-based Product Preferred Procurement Program.
Incorporating a proprietary blend of nontoxic, multimetal Vapor phase corrosion inhibitor (VpCl) chemistry, EcoLine is specifically formulated for the rigors of high-speed chains, bearings, and rollers to resist sling-off. Accordingly, VpCl molecules form a thin, tight layer on the metal surface, completely sealing it against moisture or air to prevent corrosion, product developers affirm. The lubricant is ready to use and can be applied by automatic or manual equipment. Its protection lasts up to 24 months, even in aggressive environments, the manufacturer reports. Resisting sling-off on high-speed systems, the lubricant minimizes the need for reapplication and contributes to a cleaner workspace. Cortec Corp.

CASE SETS BENCHMARK FOR BIODIESEL USE
In response to rising fuel prices, future fuel supply concerns, and customer owning-and-operating costs, Case Construction Equipment has reportedly become the first manufacturer of its kind to approve the use of B5 blends (5 percent biodiesel and 95 percent petroleum-based diesel) in all of its mechanical engines. The manufacturer also announced that the use of B20 blends (20 percent biodiesel and 80 percent petroleum-based diesel) is possible on all Case engines other than electronic engines and those in the 410 and 420 Skid Steer Loaders. Owners are advised to consult local Case dealers regarding specific biodiesel applications.
Produced from vegetable-based oils derived from renewable resources such as North American-grown soybeans, biodiesel is used in various processed mixes with standard petroleum diesel. It has been heralded as an alternative fuel with the ability to lower emissions and help reduce dependence on imported oil. B5 blends must meet the requirements of U.S. Standard ASTM6751 on the base biodiesel stock.
We do not intend to stop at B5 and B20 in our quest to help customers reduce their operating costs, asserts Case President Jim McCullough. Case is committed to working with its partners to push toward higher-level biodiesel blends that will be compatible with future low-emissions-compliant engines. We’ve initiated aggressive field tests to evaluate the performance of Case engines with 100 percent biodiesel.
While the long-term effects of biodiesel in higher-blend ratios have yet to be confirmed with current production engines, Case is continuing to study the impacts of those applications. The company also will continue to work closely with the Engine Manufacturers Association’s Biodiesel Task Force subcommittee, which works to advance biodiesel research.

The E-86 Series cartridge filters are said to offer high filtration efficiencies in compact housings. Reportedly washable and easy to replace, the 8.6-in.-diameter, spun-bonded polyester filter cartridges Û for which the E-86 is named Û permit sizing to meet differing needs. Cleaning is accomplished by a pulse jet system augmented by proprietary venturi intake ports that draw in surrounding air to increase effectiveness of the programmable reverse-air pulses. A slope-sided collection hopper mounted below the cartridge housing receives the dust and debris dislodged by the pulsed air from cartridge filter elements. The automatic cleaning mechanism uses 60 psig clean, dry air and a standard 110/1/60 power supply. The solenoid valves and solid-state timer are protected by NEMA 4 enclosures. Options include stainless steel construction, robust support structure, and a full-length access platform with ladder.

FARR AIR POLLUTION CONTROL
The HemiPleast HE (high efficiency) filter offers MERV 15 efficiency rating, coupled with as much as twice the service life and half the pressure drop of standard dust collector cartridge filters, company engineers contend. Available in filter sizes to fit a cartridge collector, the media can capture toxic and other ultra-fine dusts and works in applications where process air is recirculated downstream of the collector for energy savings. The filter combines the HemiPleat technology with an HE synthetic fine fiber media that is said to yield a filtration efficiency of 99.000 percent on 0.5-micron particles and larger. The design holds the pleats open, making virtually all the media surface available for filtration. The wide uniform spacing results in lower pressure drop, which allows dust to eject readily from deep within the pleats during pulse cleaning.
