Optional features such as pneumatic flow shutoff valves, vibratory agitation, and bag massagers further enhance its functionality. Constructed from durable materials, the Vibra Screw Bulk Bag Unloader integrates pneumatic knife gate valves for precise control over material flow, assuring a safe and efficient operating environment for handling a range of challenging materials.

Bin Activators & Bin Dischargers:

Vibra Screw - Bin Activators and Heavy Duty Bin Dischargers for Dry Bulk Material Handling

Vibra Screw offers specialized equipment for the movement and discharge of dry bulk materials from silos and bins. Their legacy began with the invention of the Bin Activator over six decades ago. These activators are crucial in preventing common flow issues like bridging and ratholing, ensuring consistent mass flow. The company provides three main designs: the Dished Head, Model HDBD with a compound slope body, and the rolled cone Bin Discharger. The Heavy Duty Bin Dischargers, designed for larger silos, combine an upper shallow section with a steep lower cone, eliminating packing and bridging without secondary baffles. Noteworthy features include a robust forged steel suspension system with elastomer isolators to minimize vibration transfer, patented beaded sleeves that resist leakage and withstand pressure, and a choice of oil or grease-lubricated vibrators designed for long service life. These products cater to a wide range of industries handling some of the most challenging materials.

Vibra Screw - Bin Dischargers for Dry Solids Processing

Vibra Screw, a company renowned for its contributions to dry solids processing, offers a line of reliable and cost-effective Bin Dischargers. With over half a century of experience, these devices are crafted with durability in mind, ensuring a long-lasting performance that meets industry standards. Their compact, leak-proof design includes a heavy-duty suspension system and long-life vibrator, making installation straightforward and maintenance minimal. Vibra Screw's Bin Dischargers are available in both carbon and stainless steel and can be delivered promptly. Particularly notable is the proprietary ASME dished head design utilized in their Bin Activators, which enhance strength and flow patterns in larger models. For smaller applications, their Bin Dischargers, with a rolled single-slope cone design, effectively prevent material packing at the outlet. This adaptability across sizes and materials makes Vibra Screw a trusted provider in the sector.

Weigh Feeders & Batchers

Vibra Screw - Continuous Loss In Weight Feeders

Vibra Screw's Continuous Loss In Weight Feeders are designed to improve the accuracy of dry solids processing by leveraging a controlled vibration mechanism. These feeders operate on a principle that balances the tare weight electronically, allowing the system to sense only the remaining material weight. The feeders adeptly adjust the discharge rate by comparing sensed and desired rates, ensuring consistent material flow even as the hopper level diminishes. Unique features include the ability to switch to volumetric control during refill and a protective disturbance mode allowing manual loading without process interruptions. Vibra Screw's design eschews ineffective paddles and agitators, ensuring a simplified yet highly efficient feed system. This technology is ideal for materials that present challenges in flowability, providing precise and repeatable feeding, making these feeders stand out in the industry.

Vibra Screw - Batch Weighing Systems for Precise Material Processing

Vibra Screw specializes in designing batch weighing systems that emphasize high accuracy and precision in material processing. These systems differ from continuous Loss-In-Weight (LIW) systems as they do not require continuous feed of materials. Instead, they are engineered to achieve precise final batch weights. The company's range includes controlled vibration feeders and material flow aids, enabling accurate loss-in-weight and gain-in-weight batching across various capacities. The design selection for specific materials builds upon Vibra Screw's extensive historical database, complemented by experimental testing. Batch systems employ volumetric rate control methods, contrary to gravimetric controls seen in LIW systems. These systems can adapt to varying batch sizes and blend different materials accurately, with options for single or dual speed operation to handle bulk and dribble feed requirements. This versatility makes Vibra Screw's batch systems suitable for processes demanding precision in weighing ingredients and supports applications like food mix preparation with gain-in-weight control.
