Triple/S Dynamic's Conveyor Reduces Product Build Up

Dallas, TX -- A solid particles processor switched to X-Force horizontal motion conveyors from screw conveyors because using the screw conveyors caused product build up and maintenance issues with the blended chlorine based powder. Chlorine powder sticks to metal surfaces and builds up over time and gets inside hanger bearings and destroys them.

Triple/S Dynamics installed two, X-Force conveyors with UHMW pans and gates. The X-Force is ideal for flakes, blended materials and coated products because of its slow advance, quick-return conveying action which significantly reduces material damage, coating loss, segregation and stratification. UHMW completely encapsulates a stainless steel core which provides the laminate with strength and stiffness.

UHMW has proven its resistance to build up from agglomerated powders, oils and sugars. The low impact motion preserves the integrity of the product conveyed, while the elimination of external springs, belts, and rollers ensures safer and sanitary operation. UHMW pans and gates eliminated product build up issues and with no bearings in the product stream, eliminated bearing maintenance. The use of natural frequency vibratory conveyors is a concern when conveying blended chlorine powder because of segregation.

The two conveyors measure, 15" W x 8" D x 72'-3" L and the other measures at, 15" W x 8" D x 33'-9" L, created significantly longer production runs with minimal downtime for cleaning and maintenance. This processor was successfully able to increase productivity, decrease downtime and reduce labor requirements.

4B Bulldog : Conveyor Belt Alignment & Rip Detection

East Peoria, IL -- The Bulldog is a new addition to 4B’s range of hazard monitoring components. A belt alignment and rip detection switch, this electro-mechanical system has been designed to detect dangerous misalignment of the conveyor and also detection of belt tear damage.

The switch will detect horizontal misalignment of belts when contact is made with the roller, the roller arm will be forced to pivot by the belt activating a switch at 15º to trigger an alarm, and 30º to trigger a shut down procedure of the conveyor. The sensors are usually installed in pairs on opposite sides of the belt.

A steel flexible wire is set below the running conveyor belt approx 20-30mm attached by a rare earth magnet at each end. If the belt is ripped or damaged the wire is pulled away releasing the magnet connection which in turn will activate a switch.

The system is easy to install and doesn’t require any calibration. Its robust design makes it suitable even for arduous applications such as quarrying and mining.  The 4B Bulldog is ATEX and IECEx approved.

The Bulldog is compatible with 4B’s CBS2A control unit for misalignment sensors and also with the Watchdog complete hazard monitoring system.

The 4B group has been serving the bulk materials handling industry for many years. 4B’s electronics division specializes in level controls, intelligent sensors and safety control systems that prevent costly downtime and minimize the risk of explosion in hazardous areas.

Mr. Golob needs help with dust collection venting:

I have encountered a problem while calculating the required venting area for our new modified dust system.

I have attached a sketch of our new system, but there is something that you must know: the inlet is not separated as shown on the sketches, but is rather made as one unit - its practically the same structure, but it covers both columns of filter modules, as opposed to the design on the sketch, where each column has its own inlet. The venting area is on the roof of the inlet.

Now here's the problem: all of the standards that cover this topic have calculations specifically for separated systems that do not have a wall in the middle separating the system in half while the inlet, where the venting area MUST be, is without that wall, and therefore represents a obstruction on the path of the explosion, the flame has to make kind of a s-turn, and the explosion will probably propagate to the other side, creating another explosion.

I have to place the venting area in the center of inlet's roof, because otherwise I will run out of space, so there is no way of simply switching the position of the venting area. There is an option of simply using a bigger vent area, but how much bigger does it have to be?

Does anyone know of any calculations and/or standard that cover this kind of design? Also does anyone know of any explosion simulation programs that I can use and are available?

For any further information please do not hesitate to contact me, Im not sure if I was perfectly clear with my description of the problem.

Thank you in advance for your answers.

Addressing Common Airlock Issues
Guest article by Cem Brinckley
Rotary Airlock, LLC

Though seemingly a small item in the overall picture, an airlock’s failure could result in something as subtle (but still costly) as a loss of efficiency – or the complete shutdown of a production line. It is important, then, to make sure the airlocks are properly functioning and maintained to bring maximum efficiency and run-time to the manufacturing process... (Click here for more)
