Why Choose JDB Dense Flow?
At JDB Dense Flow we design and build the most effective, efficient, and reliable dense phase conveying systems and components. Dense phase conveying has been our company’s primary focus since its inception in 1985, and we continue to developed our designs and components to stay on the forefront of the industry. Our systems feature an advanced air delivery system, minimal moving parts, no boosters along the convey pipeline, and proven pipeline components to insure our systems optimize efficiency, reduce downtime, and decrease maintenance costs.
At JDB Dense Flow every dense phase conveying system we design and build is individually tailored to our customer’s specific needs. Our engineering team will work with you to provide the right solution to your Dense Phase Conveying challenges. Our designs are based on the platform of building simple, reliable systems that last, and we stand behind our systems guaranteeing your desired conveying rates will be reached.
What makes our Designs Better?
When comparing one dense phase conveying manufacturer to another the basic principles are similar; it’s the components within the system, and the methods with which the basic principles are improved upon that can determine a reliable system from and unreliable one.
The answers to the following questions can mean the difference between your Dense Phase system lasting years vs. months before requiring maintenance.
- What kind of valve is used to seal the pressure vessel?
- How many valves are used to properly fill, seal, and vent the pressure vessel?
- What kind of air management system is used for conveying?
- How is the pressure within the conveying system monitored?
- Does the system require boosters? If so why, and how many?
- What pipeline components are used, and do they feature designs intended to increase lifespan?
One Moving Part
In most JDB Dense Flow systems there is only one moving part throughout the entire system. The design of our Dense Flow Cone Valve and Charging Hopper assembly allows our pressure vessel to properly fill with material, vent displaced air, and form a tight seal during material transfer. Essentially, the Cone Valve does the work of three or four valves which is common on many of our competitors systems. Using a single valve where our competitors would typically use three or four, increases our systems reliability which in turn reduces downtime and lowers costs. The Cone Valve is cast from a rugged blend of ductile iron, and features a machined sealing area that seats against an EPDM gasket. The design of the cone valve also creates a stronger seal during a material convey cycle, and it is not uncommon for a cone valve to last 15+ years before needing replacement, even in abrasive materials like sand.
Advanced Air Delivery System
Less wasted energy, lower material velocities and minimal exhaust CFM are all benefits of the Dense Flow Advanced Air Delivery System. The Advanced Air Delivery System insures our dense phase conveying systems are preforming with optimum efficiency throughout the entire conveying cycle. Through precise feedback from pressure monitoring devises our advanced air delivery system adds air only when necessary to maintain an optimal conveying pressure. By only adding air when necessary rather than a constant flow of regulated air like many of our competitors, the Dense Flow System will operate with optimum efficiency and little to no wasted energy. The advanced air monitoring system also give us the ability to control the systems shut off point at the end of a convey cycle; the earlier the system can turn the air off at the end of a convey cycle the less air it will waste, and the lower the material velocity will be at the end of a cycle. Minimizing material velocity at the end of a cycle will decrease the wear and tear on the systems pipeline components, especially those near the end of the pipeline run. These same principals will also help to minimize the amount of exhaust air the system will have at the end of a cycle, extending the life of any dust collection equipment as well.
No Boosters
At JDB Dense Flow we don’t use air boosters along our convey line because they cause two major problems: they increase material velocity, and waste energy. In a dense phase system high pressure compressed gas pushes material through a pipeline as a fluid slug. Boosters simply inject air into the pipeline during a convey cycle. So, when the fluid slug of material reaches a booster, the slug is broken up and creates less resistance. As a slug breaks up and causes less resistance the velocity of the slug increases. Not only do boosters increase velocity which in turn wears out pipeline components faster, but they add wear points along the pipeline by essentially blasting material directly across a piece of pipe. You often see pipe patches directly opposite from a booster where they’ve worn through. Also, during a convey cycle before the fluid slug of material reaches a booster it is simply dumping air down an empty pipeline, which is a tremendous waste of energy
Proven Rugged Components
At JDB Dense Flow we design and build some of the most reliable, longest lasting pneumatic conveying components available, and have continued to develop our designs over our 30+ years in the dense phase conveying industry. Through our experience we’ve designed several unique components that consistently outperform and outlast our competitors and traditional designs. Not only do our component designs improve the performance of our dense phase systems, they have helped improve other pneumatic conveying and existing competitor’s applications as well. By combining proven designs, with experienced craftsmanship, and high quality materials, Dense Flow components consistently reduce downtime and lower maintenance costs.
