TIP-TITE high-lift drum dumper
Drums loaded into the TIP-TITE high-lift drum dumper at floor level are sealed against a discharge cone, elevated, and tipped, then the cone is mated to a receiving ring on downstream process equipment. A pneumatically actuated slide-gate valve prevents material flow until the discharge cone has been properly seated in the gasketted receiving ring. The all-stainless unit can be finished to sanitary or industrial standards, whereas other models are offered in mild steel with durable industrial coatings, or with material-contact surfaces of stainless steel. The TIP-TITE accommodates drums from 30 to 55 gal (114 to 208 L) and can discharge bulk material into process vessels and equipment inlets 5 to 10 ft (1,525 to 3,050 mm) above the plant floor.

Hydraulic Bulk Bag Conditioner
The Hydraulic Bulk Bag Conditioner loosens bulk solid material that has solidified during storage and shipment, enabling bulk bag unloaders to discharge it through bag spouts. The conditioner features two hydraulic rams with specially-contoured end plates to press opposing sides of the bulk bags. An optional hydraulically-actuated, variable-height turntable allows in-frame bag rotation and conditioning of bulk bags at varying heights. The number and pressure of hydraulic ram actuations, the height of the turntable, and the number of 90-deg rotations are user adjustable. The conditioner is fully enclosed on all four sides for operator safety and includes full-height doors that are interlocked to disallow operation of the system when the doors are open. The unit is intended for bulk bags containing hygroscopic chemicals, certain types of spice blends, heat-sensitive products, and other materials prone to solidifying to the point at which pneumatically actuated flow promotion accessories integral to bulk bag dischargers are inefficient or ineffective.

dumping system for pneumatic conveying systems
This dumping station for pneumatic conveying systems collects dust during manual dumping of powder and bulk solids from bags, boxes, drums and other containers. The hopper is configured with a non-flow-through adapter for introducing material into vacuum pneumatic conveyor lines, or with rotary airlock valves or outlets for connection to flexible screw conveyors, other conveyors or process equipment. The unit features a high-velocity vacuum fan that draws airborne dust from the operator’s atmosphere onto two cartridge filters. Automatic reverse-pulse filter cleaning allows continuous operation. The station is mounted on frames with a boom and casters for mobility, and is constructed from carbon steel with an industrial finish, or stainless steel finished to industrial, food, dairy or pharmaceutical standards.

Inline pneumatic batching system
This inline pneumatic batching system allows simultaneous weigh batching of major ingredients supplied in bulk bags and manual dumping of pre-weighed minor ingredients, and blending of the material, while a subsequent batch is accumulated. Each of the bulk bag dischargers is mounted on load cells, allowing loss-of-weight batching from either or both bulk bags. A system controller starts and stops each discharger’s rotary airlock valve to weigh ingredients, first at high feed rate for rapid filling, then at dribble feed rate, stopping material flow once the accurate batch weight has been discharged. System software allows mid-batch bag changes. Minor, pre-weighed ingredients are added at the manual dumping station after the major ingredients have been discharged from the bulk bags. The dilute-phase, vacuum conveyor line terminates at a filter receiver that accumulates the batch before discharging it through a slide gate valve into a ribbon blender, allowing concurrent batching and blending of materials, cutting cycle times by half.

Half Frame Bulk Bag Unloader
The Half Frame Bulk Bag Unloader offers economical, total dust containment by eliminating the upper-frame components to lift and/or position the bag, instead relying on the user’s forklift or plant hoist to suspend the bag above the unit during operation. The bag-to-hopper interface consists of a Spout-Lock clamp ring positioned atop a pneumatically actuated Tele-Tube telescoping tube, allowing dust-tight connections and unrestricted flow between the bag spout and hopper, as well as automatic tensioning of the bag as it empties. The unit’s discharger is equipped with Flow-Flexer bag activators that raise and lower the opposite bottom edges of the bag at timed intervals, loosening compacted materials and promoting material flow into the bag discharge spout.

Manual Dumping Station
Designed to collect dust created during manual dumping of powder and bulk solid materials, this manual dumping station with integral flexible screw conveyor features a high-velocity vacuum fan that draws airborne dust from the operator’s atmosphere onto two cartridge filters. Automatic reverse-pulse filter cleaning allows continuous, efficient operation; timer-activated solenoid valves release short blasts of compressed plant air inside cartridge filters causing dust build-up on the outer filter surfaces to fall into the hopper. Filters are accessed easily by removing the interior baffle, and replaced rapidly using quick-disconnect fittings. The flexible screw conveyor is said to handle freeand non-free-flowing bulk materials ranging from large pellets to sub-micron powders, including products that pack, cake, seize, smear, fluidize, break apart or separate.

BFC Series Weighing/Batching System
The BFC Series weighing/batching system features bag activators that raise and lower the opposite bottom edges of a bag at timed intervals, loosening compacted materials and promoting material flow. Each discharger is equipped with a surge hopper that discharges into an enclosed flexible screw conveyor. A controller starts and stops the conveyors to weigh ingredients in sequence, first at a high feed rate for rapid filling, then at a dribble, stopping flow when the desired weight has been discharged. The controller then activates a rotary airlock valve to release the batch into a pneumatic conveyor line, which terminates at a filter receiver above a ribbon blender. Components are made from carbon or stainless steel.
