Foundries have extensive dust collection systems throughout their plants. Most of the collected dust is disposed of at a landfill. Prior to leaving the foundry, the dust is sometimes required to be conditioned to a dustless mixture before a landfill will accept it. This can be accomplished using a large paddle mixer, Turbin mixer, or planetary style mixer.
These dual bulk bag fillers efficiently fill big bags with raw material such as sand, cement, bentonite, plastic pellets, fertilizer and more at a rate of 20-25 bags per hour. A single pallet is discharged from the pallet dispenser. A slip sheet dispenser then applies a slip sheet on top of the empty pallet before it is loaded in to the filling station. Bag filling starts with a push of a button and bag is filled to set target weight. Final product is conveyed to end of the line where a robotic forklift moves the bag to a warehouse for storage and shipping.
Gravity Flow Open Mouth Bagger used to fill fertilizer bags
A fertilizer bagging machine, such as the Gravity Flow Open Mouth Bagger (GWB), fills open mouth bags with dry, free-flowing and minimally dusty fertilizer granules at a rate up to 5-8 bags per minute (300-480 bags per hour). The bags most commonly used with this machine are an open top poly bag or a poly-lined paper bag. The bags are filled to a 50-pound target weight.
The CBE Model 250 Re-Bagger allows for recycling and repackaging of rejected material from existing open mouth and valve bags into valve bags. This bag filling machine is capable of filling up to 5 bags per minute.
The volumetric auger bag filler with a high intensity densifier is used for filling bags with light weight fibrous materials such as linted cottonseed hulls, cedar fiber and synthetic fibers.
The video below shows a robot that stacks filled 50 pound paper valve bags onto a wooden shipping pallet located on the floor per the programmed bag placement design. This robot was added to an existing bag filling system to reduce labor costs.

This flour bagging machine fills and seals valve bags at a rate of 3-4 bags per minute with good weight fill accuracy. Filling can be mostly dust free with this type of flour, but dust collection is still recommended. This is a proven design refined over many years to give users an accurate fill weight. It is ergonomically designed to reduce repetitive motions and have a quick fill time with convenient access for maintenance.

After the flood waters recede from a large storm like Hurricane Harvey, there will be many buildings and homes that will need to be repaired or completely demolished due to flood and wind damage. The resulting construction and demolition debris and material can be processed to separate and recover materials such as OCC, wood, ferrous and non-ferrous metals, rock / cement, dirt / ADC, plastics. Using an automated C&D Waste Recycling Plant can greatly decrease the manual labor necessary to sort through many thousands of tons of debris and waste.

Air-powered stainless steel vibrating tables are used to settle solids in sludge stored in 55 gallon steel drums. The customer wanted to remove excess moisture from the solids. Upon vibrating the drum, solids move to the bottom of the drum and the moisture is separated to the top of the drum where it can be removed before the lid is secured.
Wooden shipping pallets are shredded or ground up and are conveyed to a storage pile using a belt conveyor. An overhead self-cleaning magnet can be used over the belt conveyor to remove tramp metal, staples and nails before the material is fed onto the pile. The magnet can be designed to fit conveyor belt width and speed.
