Higher pressure would produce finer droplets and broaden the spray angle to some extent.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">However, this would not sufficiently address clogging caused by dust adhering to the nozzle orifice. Moreover, if the pump-to-nozzle water line was not designed for higher pressure, increasing the discharge pressure could require new piping work. For these reasons, he determined that increasing pump pressure alone would not be a sufficient solution.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Therefore, he proposed replacing the existing nozzle with the <span style=\"font-weight:bold\"><a href=\"https:\/\/www.dry-fog.com\/en\/products\/noz-pne-bimv\/\" style=\"color: #00a273\" target=\"_blank\" rel=\"noopener\">BIMV<\/a> pneumatic spray nozzle<\/span>, which mixes compressed air with water to atomize the liquid and produce a spray. Compressed air creates sufficient spray spread to <span style=\"font-weight:bold\">cover the entire conveyor surface uniformly<\/span>. In addition, airflow at the orifice helps blow away adhering dust, <span style=\"font-weight:bold\">preventing dust buildup and minimizing clogging<\/span>.<\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n        <img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/05\/nozzle-environ-017-image_4.png\" alt=\"BIMV Series pneumatic spray nozzle\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><figcaption style=\"margin: 1rem auto 3rem;text-align: center;font-size: 0.85rem;color: #666\">BIMV Series pneumatic spray nozzle<\/figcaption><\/div>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Fortunately, a compressed-air supply connection was already available nearby, so the required work was limited to replacing the nozzle and connecting tubing. Despite a modest increase in operating cost, the facility approved implementation because the proposed solution was expected to improve both dust suppression and clogging resistance.<\/p>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin: 0 auto 2rem;border-left: 5px solid #0c9b6f\">Benefits Achieved<\/h3>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">After switching to the BIMV Series, the system produced a uniform flat-fan spray pattern with finer droplets at the same pump discharge pressure, covering nearly the full conveyor width.
