Profile: Butler-Justice, Inc. specializes in offering industrial equipments, parts and service. We design blue smoke control systems for the hot mix asphalt industry. Blue smoke actually appears as tiny oil droplets that make-up the blue haze that is typically associated with paving as well as applicable in the production of hot mix asphalt. It is the blue haze that carries much of the characteristic asphalt odor. Air pollution control agencies are becoming more concerned with blue smoke, especially as RAP, rubberized asphalt and polymer blends are more routinely specified. These specialty mixes produce an increased amount of blue smoke. The blue smoke control filter cartridge is made from proprietary filter media developed exclusively for collecting oil mist. This media, combined with a special outer wrap, allows the filter cartridge to drain and prevent the collected liquid from entering the clean air stream. These control filter cartridges sit vertically inside the collector, allowing gravity to aid the draining process. The result is more complete in capturing the oil droplets, for easier maintenance and has higher filtration efficiency. We also offer conveyor belt scales for various industries including mining, portable crushing, scrap, and agriculture. Conveyor belt scale features an easy to install modular design. We provide various crushing products including horizontal shaft impact, jaw and vertical shaft impact crushers.
