The washable media is resistant to moisture and can handle heavy dust loading conditions and/or hygroscopic or sticky dusts. The filter uses a lightweight, 100-percent spun bond polyester media in a pleated design that maximizes surface area while maintaining open pleat spacing. The wider spacing of the pat- ented HemiPleat design exposes more media to the air stream, resulting in lower pressure drop and improved dust release during pulse cleaning. Sturdy and durable, the moisture resis- tant media may be washed and reused in many applications with operating temperatures up to 160 F. HemiPleat Synthetic is available in a standard version or a nanofiber media version that uses Camfil APC's proprietary "eXtreme" media technology. The nanofiber layer acts like a pre-filter that enhances surface loading of dust, keeping most particles from embedding in the base media. This enhances the filter's efficiency as well as its cleaning ability for longer service life. The standard media is rated at MERV 11, and the nanofiber media is rated at a MERV 15 filtration efficiency based on the ASHRAE 52.2 test standard, noted the company. HemiPleat Synthetic filters are available for Farr Gold Series dust collectors or for retrofit on most major brands of car- tridge dust collectors.

Ltd. has commissioned Loesche with the delivery of two vertical roller grinding mills for the new INVECEM Industria Venezolana del Cemento plant in Monay, Venezuela. The Monray cement plant is a joint project of both the gov- ernments in Venezuela and China, who have agreed to build three cement plants in Venezuela, each with a production capacity of 2,500 tpd. The LM 48.4 Loesche vertical roller grinding mill will grind cement raw material with a capacity of 280 tph at 12 percent R 0.09 mm at the Monay plant. The LM 53.3+3C cement mill will produce 200 tph of ordinary portland cement with a fineness of 3,200 Blaine. Delivery of LDC classifi- ers and mills is planned f o r N o v e m b e r 2 0 1 5 . T h i s o rd e r i n c re a s e s the number of Loesche vertical roller grinding mills in the Venezuelan cement industry to sev- en mills and generates synergy effects due to the Loesche identical parts concept, noted the company in a released statement.
