Dust Collector
Besser’s DCS-270 Shaker Baghouse, a new model in its line of dust collectors, handles 550 cfm of air volume with a 2.1 air-to-cloth ratio. The model features a 43.5-in.-diameter housing with a unique center column design. The shaker mechanism utilizes a maintenance-free, turbine vibrator that shakes the bags in an elliptic rotation around the collector’s center column. Bags in the DCS-270 undergo automatic cleaning cycles at pre-set time intervals based on production. Consistently timed cleaning cycles controlled by programmable logic circuitry extends bag life and reduces maintenance costs, according to the manufacturer.

The new Smart DI+ design reduces the amount of force required to set the anchor. What used to take about 20 hammer blows on a typical 3/8-in.-diameter part can now be accomplished in approximately five blows, thus reducing overall labor costs by approximately 50 percent, according to the manufacturer. The cylindrical plug design concentrates more expansion at the bottom of the anchor where it’s needed to maximize performance.

Chief Economist Ed Sullivan attributed highway-funding legislation uncertainty in calling for a 0.6 percent 2011-12 cement consumption increase over a 2009-10 trough. A previous forecast that might have seen cement shipments this year and next combine for an 8–10 percent gain factored a 20 percent increase in federal highway funding, which PCA now sees will continue at its present level.
