Rock & Roll with Belt Conveyor System Solutions

With one huge scoop, you grab the rock and stone in front of you, collecting it in the bucket of your front-end loader. You move forward, ready to dump the material into the load chute of the conveyor. Someone gives a shout, arms waving and signaling you to stop: “Hold up! We’ve got a jam.” The belt conveyor is down again for maintenance, and you’ve got some time on your hands; this could mean several hours of downtime for the team.

Hauling components is an important part of the production processes of varying industries including concrete, chemical, mining, wastewater treatment, and more. Within these bulk handling operations, belt conveyors are an economical way to transport materials of varying sizes.  Continue reading “Rock & Roll with Belt Conveyor System Solutions”

An Introduction to Pneumatic Conveying

When walking through the grocery store and picking up a bag of flour or sugar, you’ve probably never thought about the process that it took to get these items packaged. The small particle size of these materials requires specialized handling to ensure there is minimal damage or loss, which is called pneumatic conveying.

A pneumatic conveying system works by moving the material through an enclosed conveyor line using a combination of pressure differential and the flow of air (or another gas) from a blower or fan. Pneumatic conveying systems can be used to transport cement, starch, sugar, salt, polymers, plastic powder, and other powdered/granular bulk materials. The two most common forms of pneumatic conveying systems are dilute phase and dense phase.

Manufacturing an Economic Dust Filtration System

Solenoid Valve Enclosure with Timer, Series SVT

Many customers have come to the Dwyer team asking: “What can Dwyer do to help with lean manufacturing?” In this article, we will discuss the Dwyer® Series SVT solenoid valve and timer enclosure and its cost savings advantages in a dust filtration system.

The Series SVT combines two integral components in a dust filtration system into one package: solenoid valves and a timer controller. In a dust filtration system, solenoid valves are used to send air through a pulse valve, such as our Series RDCS.  Pulse valves release a quick spurt of air into a dirty dust cartridge filter, which, in turn, releases the dust from the filter. The timer portion of the dust filtration system is the brains of the operation controlling when the solenoids fire, the amount of time the solenoids are open, and when the next solenoid in the sequence fires.
