Tubular Drag Conveyor
2Pages

Conveyors Continuously move material in any direction without dusting Tubular Drag Low-horsepower, electric motor drives material for hundreds of feet using minimal energy. Prevent material from getting trapped with the exclusive, self-cleaning discharge gate. Convey any bulk solid or powder – from abrasive to high-moisture materials – in a completely sealed system. Hapman engineers will select the correct chain and flight design to meet your specific requirements. Confine materials to the process without dusting, odors, contamination or spillage. Improve product discharge with optional mechanical vibration that dislodges material from flights. Continuously convey materials up to 50 ft3/min. (1.4 m3/min.) in any direction. Keep material in and contaminants out. •• Convey product in a completely sealed system. The sprocket drive slowly pulls a heavy-duty chain through a fully enclosed casing. As the chain moves your material through the pipe there’s less chance for dusting, explosions or product-spoiling contamination issues. •• Use less energy than other conveyors to move powders or bulk solids. The low-horsepower motor produces the slow, steady drag that cuts your energy costs. •• Move challenging materials. Convey high-moisture ingredients, abrasive, blended, friable, easy-to-compact or smear products without compromising quality. A true performance guarantee ensuring your Hapman equipment achieves the specific results it was designed and manufactured to deliver. And if you need technical support, call us. We are available 24/7. •• One conveyor does the work of several, no problem. Configure your tubular drag to convey your product vertically, horizontally, at any angle and around corners. Need more than one inlet/outlet in your process? Add as many as you need. © 2010 Hapman. All rights reserved. Take a free test drive! Contact: sales@hapman.com www.hapman.com
