Industrial Hemp Production Surges
Industrial Hemp, cousin to Marijuana but without the effect, has been a usable fiber for over 50,000 years. Used to make commercial items ranging from paper, textiles, clothing, plastics, paint, food, animal feed and biofuel, it is seeing a resurgence over other natural fibers such as wood because: it yields four times the crop per […]
Process weighing and gravimetric control technology … is it new or old?
Figure 1 A load cell usually consists of four strain gauges in a Wheatstone bridge configuration. Figure 2 The strain gauge load cell changes resistance proportional to the tension or compressive force acting on it. Figure 3 A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs […]

Can you afford to get caught without a critical part?
You can’t drive your car forever with the same oil, brakes, muffler and tires. Periodically it will need to be serviced. Solids processing equipment is no different. It needs to be properly maintained in order to perform within its design parameters. And, eventually certain parts will need to be replaced. Maintaining a spare parts inventory […]
Bin Activators Cure Material Segregation
Picture what happens when you pour a mixture of stone and sand on the ground. A rough cone forms, with stones mainly around the outside and sand mainly in the center. The stones tend to roll down the surface of the cone as it is formed, while the sand sifts down closer to the center. […]
“Controlled Vibration” enhances screw feeder performance
Non-free-flowing dry solid materials are a challenge to feed consistently and uniformly in volumetric & gravimetric screw feeders. Materials that tend to be readily adhesive (TiO2, foundry sand, pigments) or become easily fluidized (hydrated lime, cement, talcum powder, confectionary sugar, fly ash) can be quite difficult to feed. The simple and proven solution is the […]
Bin Activator Sizing Made Simple
Since its introduction over 50 years ago, the Bin Activator has become the most widely used bin discharge device in the process industries. It can be used on new or existing bins, and it will discharge virtually any dry material. In most cases, a successful Bin Activator installation is simply a matter of picking the […]

The agreement, covering North America, gives Vibra Screw access to Mavi’s 50 years of experience which has made it the largest supplier of vibrating feeders and conveyors in South America. Using the […]
Attaching a Bin Activator To a Silo … More Than Just Nuts and Bolts
Bin Activators are one of the most successful devices for ensuring flow of bulk material from storage. They can range in diameter from a couple of feet to 18 feet. Bin Activators can be extremely heavy, and while being subjected to vibration, must support the head load created by additional tons of material in the […]
