Motive air flows through a nozzle at high velocity. This creates a vacuum that draws the bulk material in from a hopper or feed. In the downstream mixing zone, the material is entrained by the air jet, accelerated and pushed into the conveying line.   <\/p>\n\n<h2 id=\"injektordusen-und-lavaldusen\" class=\"wp-block-heading\">Injector nozzles and Laval nozzles<\/h2>\n\n<p class=\"wp-block-paragraph\">How efficiently an injector operates depends largely on the shape of the motive nozzle. For applications with high air velocities, <a href=\"https:\/\/ratec-systems.com\/en\/laval-nozzles\/\">Laval nozzles<\/a> are used to accelerate the airflow in a targeted way and improve flow dynamics. We determine which nozzle shape suits your conveying task during the design phase.  <\/p>\n\n<h2 id=\"ihre-vorteile\" class=\"wp-block-heading\">Your benefits<\/h2>\n\n<ul class=\"wp-block-list\">\n<li><strong>No moving parts:<\/strong> simple design, low wear, minimal maintenance.<\/li>\n\n\n\n<li><strong>Compact:<\/strong> easy to integrate into existing systems.<\/li>\n\n\n\n<li><strong>Continuous conveying:<\/strong> consistent transfer of bulk material into the line.<\/li>\n\n\n\n<li><strong>For medium distances:<\/strong> efficient pneumatic transport without major system complexity.<\/li>\n<\/ul>\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"399\" src=\"https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/06\/Injektorduese-1-1024x399.webp\" alt=\"Injector nozzle\" class=\"wp-image-2846\" title=\"\" srcset=\"https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/06\/Injektorduese-1-1024x399.webp 1024w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/06\/Injektorduese-1-300x117.webp 300w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/06\/Injektorduese-1-768x299.webp 768w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/06\/Injektorduese-1-1536x598.webp 1536w, https:\/\/ratec-systems.com\/wp-content\/uploads\/2025\/06\/Injektorduese-1.webp 1992w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<h2 id=\"technische-eckdaten\" class=\"wp-block-heading\">Technical specifications<\/h2>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Feature<\/th><th>Injector nozzles<\/th><\/tr><\/thead><tbody><tr><td>Principle<\/td><td>Jet pump, motive air draws in bulk material<\/td><\/tr><tr><td>Conveying type<\/td><td>pneumatic conveying over medium distances<\/td><\/tr><tr><td>Conveyed material<\/td><td>Powders, granulates and other bulk materials<\/td><\/tr><tr><td>Nozzle shape<\/td><td>depending on the application, e.g. as a Laval nozzle<\/td><\/tr><tr><td>Dimensions, materials<\/td><td>customized for each plant<\/td><\/tr><tr><td>Special versions<\/td><td>on request<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">We redesign nozzle geometry, connections, materials and wear protection for every project.
