Acrison's Model 820 Bulk Bag Unloader provides a clean, safe and highly effective means for discharging a wide assortment of dry solid materials from within various size and type bulk bags. The bags can be placed (lifted) into the unloader by a fork truck or hoist. When loaded with a fork truck, the unloader's structure includes adjustable bag rack guide rails with tapered side guides to help align and locate the bulk bag during the loading process.
Especially effective in the discharge of non-free flowing materials, the Model 820 Unloader utilizes 'controlled vibration' to reliably discharge the entire or partial contents of bulk bags, typically for use in conjunction with Acrison metering equipment. The bags can weigh up to two tons and can be disposable, reusable, or lined.
The Model 820 Bulk Bag Unloader features Acrison's patented Model 82-SCM Bag Spout Clamping Mechanism for unrestricted access to the bag’s discharge spout for attachment to the process interface transition in an entirely clean and dust-tight manner; it also maintains the spout taut during the bag emptying process. Attachment is easily and quickly made by a strong, yet simple manually operated clam-shell clamping system.
The Model 820 can also be optionally equipped with Acrison's Model 82-SCV 'Bag Spout Closure Valve' that will close off the bag's discharge spout (allowing it to be retied) when it's desired to remove a partially empty bag. The pneumatically operated (patented) spout closure valve consists of a series of flexible coated steel cables that converge around the center of the discharge spout forming a tight 'basket weave' closure.
To ensure a completely dust-free operation, the Model 820 is available with dust collection means (that also assists deflating an empty bag), and bag lifting racks that automatically maintain upward lift on a bag (and bag liner when applicable) to facilitate product discharge.
