RMPS is an automated blade molding facility unto itself, capable of spraying in-mold coatings, dispensing/lay-up of glass and carbon fiber materials, and dispensing/application of adhesive.

On the finishing side of blade automation, MAG will introduce a five-axis machining system for root drilling/milling/sawing. For metalworking production of wind-power parts, MAG is introducing a new line of horizontal turning centers (HTCs) in the U.S. that combines a wide array of unusual capabilities for finishing a large part in one setup.

CSF supplies

Automation Systems Interconnect Inc. has added to its line of CSF power supplies. Compared to the previous model the new CSF series will save up to 30 percent more DIN rail space at only 1.53 inches wide for a 5 amp power supply. Included is short circuit, overload, over temperature, input/output overvoltage protections. In addition, there is a high outrush current to guarantee downstream blown fuse indication and to start-up heavy loads. Controlled by a voltage threshold, all power supplies are equipped with an output voltage alarm contact that indicates when the voltage drops under 90 percent of the rated value.

Ball valves

Strahman Valves has announced a new, metal-seated ball valve designed for ease of maintenance in severe service applications such as in the delayed coking units and hydrocrackers found in the petrochemical and refining industries. The ball valves come in either one-piece or two-piece construction, and are trunnion mounted, enabling them to withstand high pressure, high temperature and abrasive environments.

The valves come with numerous options, ranging from bore size, to body and trim materials, and welded jackets around the body and flanges, as well as others.

Crusher granulator

With three models and nearly 50 sizes available, Pennsylvania Crusher’s Granulator can accept feed sizes of up to 12”. Able to handle any type of coal, including low quality coals that may be wet, frozen, high in fines or high in ash content, the Koal King combines rolling compression and shear to produce high reduction ratios at high capacities while minimizing fines.

The inside of the machine is easily exposed for maintenance and inspection. Inspections and maintenance can be conducted without disrupting the feed system. An optional hydraulic door opener makes rigging the open rear quadrant totally unnecessary.

Flowserve guide

Flowserve Corp. a flow control products and services company, has released a new valve cavitation teaching and selection guide. Flowserve Cavitation Control is a comprehensive guide featuring detailed information about the causes of cavitation and a presentation of the latest cavitation control technologies for both linear and rotary applications. Even low levels of cavitation can cause cumulative damage to piping and valves if adequate protection is not provided, potentially resulting in equipment failure. Cavitation is avoided by gradually reducing the pressure drop from inlet to outlet through a variety of control mechanisms. Accurately predicting cavitation and applying the correct control mechanisms is critical to a successful, cost-effective solution.

Needle valves

High Pressure Equipment Co. has developed a new line of block and bleed needle valves operating up to 20,000 psi. These new needle valves are offered in both single and double block and bleed configurations. Both valve styles have Type 300 stainless steel tee handles with a non-rotating stem design as well as with optional wetted parts and optional O-rings available.

High Pressure Equipment Co. designs, manufactures, and markets products used in the chemical, petrochemical, oil and gas, waterjet cutting and blasting, industrial research and development, general industrial, university and pharmaceutical industries. These products include high-pressure valves, fittings and tubing, reactors, pressure vessels, intensifiers, gauges, pumping systems, gas booster systems and pressure generators.

Cage mills

Stedman offers a variety of size reduction equipment including several cage mill series, “A”, “F”, “G”, “H” and “Y”, with specific models available for wet, sticky materials and blending or cleaning products. Stedman custom builds their cage mills to fit each crushing, pulverizing, blending and mixing application of abrasive or non-abrasive materials. Many companies in industries such as brick and clay, shale, detergents, fertilizers and others rely on Stedman for sizing of materials to maximize yields to a close range. Typically after crushing, the oversize material will be returned to the cage mill for further reduction and fines are returned to the compactor. The cage mill line offers varying maximum capacities from 70 to 240tph and models featuring single-, two-, four- and six-row cages.

RCI pump

RCI Technologies introduces the FRS 660-11-DPU-UL (DPU), the newest addition to RCI’s line of diesel fuel purifiers and fuel recirculating systems. The DPU, or Duplex Pump Unit, is the newest model of RCI’s Fuel Recirculating Systems (FRS). It is designed to automatically circulate and clean the fuel in customers’ fuel storage tanks on a preprogrammed schedule. The DPU features two fuel pumps, which operate alternately to circulate the fuel through the system. RCI’s other FRS units utilize a single pump.

All FRS units employ RCI’s patented filter-less technology, using no filters or moving parts. The FRS is used for primary fuel purification and removes free water, including emulsified water, and up to 98 percent of the normal solid or particulate contaminates found in fuel, including sludge and algae.

Dust caps

Martin Engineering has introduced Martin Dust Caps to prevent the problems of material accumulation and corrosion at the base of conveyor structures. The buildup of fugitive material on the floor or ground around belt conveyor supports creates a mess and potentially a fire hazard. These buildups also capture moisture, leading to the corrosion and weakening of the conveyor structure. Installed on the “legs” of the conveyor, Martin Dust Caps prevent these material accumulations.

Made from accumulation-resistant molded polyurethane, Martin Dust Caps are pyramids that cause the material to fall away from the conveyor foot, making it easier to collect dust and clean it by washing down or sweeping around the conveyor.

Deere engines

John Deere Power Systems (JDPS) has announced the technology solutions it will use to meet Interim Tier 4/Stage III B mobile off-highway emissions regulations for the company’s complete lineup of industrial diesel engines. These regulations require at least a 90 percent reduction in particulate matter and up to 50 percent reduction in nitrogen oxides (NOX) from previous Tier 3/Stage lll A requirements.

JDPS will continue to offer the familiar John Deere PowerTech displacements of 2.4L, 4.5L, 6.8L, 9.0L and 13.5L. Power ratings will also be similar to the Tier 3/Stage III A offerings. For all of its engines 56 kW (75 hp) and above, John Deere will start with Tier 3/Stage III A PowerTech Plus engine platform, which includes cooled exhaust gas recirculation (EGR) for NOX) control, and add an exhaust filter for reducing particulates. Displacements in this power range include the 4.5L, 6.8L, 9.0L and 13.5L in-line, four- and six-cylinder engines, all of which feature a four-valve cylinder head, high-pressure fuel system, turbocharging and an air-to-air aftercooling system. As with previous emissions tiers, John Deere will offer appropriate levels of technology for specific customer needs in a wide variety of applications.

Atlas testing

Atlas Material Testing Technology introduces a new technology for ultra-accelerated exposure testing. This outdoor testing device can provide approximately 63 years of South Florida UV radiation exposure in a single year. Atlas developed this new solar concentrator technology in partnership with the National Renewable Energy Laboratory (NREL) and the Russian Institute of Laser Optical Technology (ILOT) under a U.S. Department of Energy (DOE) program.

Similar in concept to Atlas’ moderately accelerated EMMA technology, the ultra-accelerated device tracks the sun while concentrating reflected sunlight on test specimens mounted in a target area. The new patented mirror system used in the ultra-accelerated concentrator has very high reflectance in the UV and near visible wave length ranges while attenuating reflectance in the longer wavelength visible and IR portions of the solar spectrum. This technology allows for very high concentrations of UV energy without excessive heating of test samples.
