NBE-Drum and Tote Filling System

Application Notes & Case Studies /

Application Overview: This customer required a semi-automatic filling station, complete with controls, that will accommodate filling a wide variety of containers, including 55-gallon drums and 275-gallon IBC totes. Operators will manually load and unload the palletized drums and totes including handling of the bung. A manual pneumatic bung sealing tool is included post-filling. When accompanied with the appropriate pump, and configured for the proper fluid properties, the filling station can fill a 55-gallon drum in ~45 seconds. The filler is equipped with state-of-the-art bung location assistance to increase productivity while making the operator’s job easier. This system includes a total of 11 chain-driven live roller conveyors, (6) pre-filling and (5) post-filling. A profile cut V ball valve is utilized to control the flow of liquid into the filling lance, a closing tip on the end of the filling lance mitigates the dripping of the product. The fluid added to the totes and drums is measured by load cells built into the integrated conveyor section of the filler. The load cells will be connected to an integrated HMI control system that will control the valving (pumps by customer)that supply the flow of material

NBE-Bag Opening System-Carbon Black

Application Notes & Case Studies /

This customer had been opening 50 lb. bags of carbon black manually and wanted an automated system for improving the health and safety of their team, along with adding efficiency. This started with an engineering PO after an NBE teammate made a visit to their plant in snowy conditions right beforeChristmas. There were a lot of changes in the layout and scope, but we ultimately settled on this final configuration : The operator will load bags onto an incline feed conveyor, which runs through a cutting head with a 30” diameter blade. The cut bags enter the rotary separating drum that will screen out carbon black from the bags. The carbon black falls through the screen openings in the drum and transitions through a hopper with a slide gate and into customer supplied totes. The empty bags automatically discharge out the end of the drum and drop into a screw-type bag compactor

NBE-Bulk Filling System-Potato Slices

Application Notes & Case Studies /

The customer approached NBE, aware of our industry reputation for problem-solving and efficient solutions, to enhance their packaging operation. Due to the diverse types of materials they handle, their packaging often ends up uneven and inconsistent. Some materials would accumulate with a high angle of repose, leading operators to use a forklift to “bounce” the totes to level them out, causing spills. This impacted both plant cleanliness and packaging accuracy. NBE was engaged to develop a solution that enables precise tote filling by weight while densifying the contents for consistent, shipment-ready packages. Currently, the customer operates over 12 units, including stand-alone systems, units with diverter gates, and infeed/outfeed conveyor configurations, with additional units under consideration. These are two systems, each with two filling stations and a shared control panel.

Rapid blending of nutraceuticals in a restricted space

Application Notes & Case Studies /

The rotary blender produces a homogeneous mixture while gently folding and tumbling the material, preventing product degradation. The unit’s internal mixing flights alternate in direction for “back flow blending,” an active, gravity-driven cascading of the material back and forth as it passes through the vessel, which is turning at low rpm. The resulting mixing action is said to preclude the product degradation and heat build-up associated with ribbon blades, paddles, or plows being forced through material contained in stationary mixing vessels.

Output of Livestock Feed Supplements Doubled Using Rotary Batch Mixer

Application Notes & Case Studies /

Improving its mixing operation enabled the company to double production. “We purchased a Rotary Batch Mixer from Munson in 2014 to increase production capacity,” he says. “Although the mixer has a three-ton capacity, we typically mix about two tons (1.8 metric tons) at a time. Daily throughput is about 15 tons (13.6 m t),” Reddy says, “and 300 to 400 tons (272 to 363 m t) per month, depending on demand for product.”

Nutraceutical Blending Cycles Cut 90 Percent with Switch to Rotary Batch Mixing

Application Notes & Case Studies /

The V-cone blenders did the job on the existing calcium and vitamin D production lines, but typically were taking 45 to 60 minutes per batch to achieve the desired uniformity, prompting the purchase of a 40 cu ft (1133 l) capacity stainless steel model 700-TS-40-SS Rotary Batch Mixer from Munson Machinery. The unit contains internal mixing flights that tumble, cut, turn and fold the batch, causing particles to recombine 288 times per minute, achieving batch uniformity in four minutes, or 11 to 15 times faster than the company’s V-cone blenders. The company also gained production flexibility, as the mixer is equally efficient from 100% down to 15% of rated capacity.

Metering Hot Lime from Silo at International Paper

Application Notes & Case Studies /

The new KWS slide gate and screw feeder were constructed using heavy-duty 304 stainless steel to withstand high temperatures of the hot lime stored in the hopper and occasional foreign objects that inevitably travel through the system. The screw feeder trough was equipped with a clean out port to allow maintenance operators to pull out foreign objects with ease. The drive unit produces extreme high torque to power through upset conditions. A KWS torque arm trough end allows the gear reducer to “float” while producing torque. The screw was mass-flow design to promote even withdrawal of material from the hopper and to meter hot lime at a controlled rate. KWS provided a slider base trough end on the tail end of the screw feeder to account for thermal expansion due to high heat.

Dryer Feed Screw Conveyor for Koppers Performance Chemicals

Application Notes & Case Studies /

The new KWS screw conveyor was redesigned to bolt directly to a dryer, eliminating a transition chute. To reduce clean out time, KWS designed and manufactured a split tubular housing with multiple doors for easy access. The special hinged design allows the doors to be opened from both sides and provides the option to completely remove the maintenance door. The split tubular housing design meets all OSHA safety regulations and requires special tools for removal by qualified maintenance personnel.

Continuous Bucket Elevator for Wood Fiber Recycling Plant

Application Notes & Case Studies /

Though centrifugal bucket elevators are the most common design for elevating bulk materials, attempting to discharge a low-density bulk material such as wood fiber would lead to much of it free floating within the elevator housing. A continuous bucket elevator allows the material to discharge by gravity and slide out of the bucket, using the back of the preceding bucket as a ramp. Such a controlled discharge is preferred to maximize transfer efficiency. In addition, a belt-type elevator was used rather than a chain to avoid open areas where wood fibers could potentially snag and form clumps.
