Rotary Grate Magnets for Powders & Poor Flowing Bulk Solids
Rotary grate magnets remove ferrous metal from dry powders and other bulk solids that have poor flow characteristics. These types of solids also have a tendency to bridge and choke, when using stationary tube style magnetic separators. Sizes range from 8″ by 8″ up to 18″ by 18″ outlets with custom designs available to fit your exact specifications.
Magnets, such as these large tube rare earth magnets, are used inside of recycling systems that process recoverable materials like paper. This type of magnet would be installed after the paper shredding step inside of the recycling stream. The magnets catch stray nuts, bolts, staples, paper clips, and other metal objects before they reach downstream grinding equipment. They also collect fine metallic particles to ensure a metal-free, recycled paper product. Removal of the collected metals is accomplished using the EZ-clean and self-cleaning design on the magnet.
This video shows a magnetic drum that removes ferrous metal from a recycling system. These rugged types of magnetic separators have a heavy-duty manganese wear shell that protects against damage from large or sharp objects.
First, an empty valve bag is placed on the valve bagging machine spout. During the fill cycle, the low frequency oscillating (or reciprocating) densifier is activated to settle and densify the material inside the valve bag. This allows for complete filling of the bag to reach a set point weight. Other types of densifiers are also available.
A bag flattener conveyor is designed for flattening both filled valve bags and open mouth bags to make them more uniform in shape to stack on a shipping pallet. They are flattened as they move through two conveyors with the upper conveyor applying adjustable force to the top of the bag. Typically, the bag flattener also acts as an incline conveyor that elevates the bags to the inlet of a palletizing station.
An ultrasonic valve bag sealer is a specialized piece of equipment designed to provide a clean and efficient solution for sealing valve bags. The process involves sealing the bag before it is discharged onto a conveyor, which minimizes product spillage and migration to the surrounding environment. The sealer hermetically seals filled bags with an ultrasonically sealable valve sleeve, ensuring a high level of cleanliness during operation.

Valve Bag Sealer
An auger filler integrated with an ultrasonic valve bag sealer is a versatile machine that can bag and seal a variety of powders, especially those requiring quick cleanout between packaging runs. The machine shown in the video is ideal for sanitary uses or for any application where cross-contamination must be prevented. It uses an auger to fill valve bags with powdery products and ultrasonic technology to close and discharge the bags.
This type of auger filler is designed to handle a bag filling weight range of 20-110 lbs. and can achieve a production rate of 1-3 bags per minute, depending on the material and bag size. It can accommodate a material density range of 20-75 lbs. per cubic foot. The auger filling machine can operate in semi-automatic (operator-assisted) or fully automatic modes and is compatible with sonic sleeve paper and plastic film bag types. After filling and sealing, the bags drop onto a wire mesh discharge conveyor and then move toward a manual palletizing or robotic palletizing system.
Examples of materials that can be bagged with this machine include flour, bakery mixes, cocoa, spices, pepper, animal grade pharmaceuticals, and nutraceuticals. The interior moving parts, such as the auger and agitator blades, can be easily removed for cleaning and inspection, making it a practical choice for industries that need to switch between different products frequently.
This simple, economical bag sealing system allows a single operator to fill and heat seal up to 4 plastic or foil bags per minute. The bagging system includes an 8 foot long bag closing conveyor, a clamp type heat sealer with mounting pedestal, and variable speed bag indexing controls to control the speed of the filled bag on the take away conveyor.
The filled bag heat sealing system can be used with most of the open mouth baggers that we sell.
Auger fillers convey golf course sand into 50 lb. valve bags at a rate of 1-5 bags per minute. They simultaneously fill and weigh the sand directly into the bags.
These types of valve bag filling machines are also used to fill bags with other types of powdery or small granular materials such as:
This material transfer system conveys the contents of a bulk bag into 10 to 100 pound valve bags. It can be used to transfer materials such as powders or small granules including finish cement, bentonite, barite, fertilizers, frac sand, powdered limestone, gypsum, powdered iron ore, oil drilling chemical powders, titanium dioxide, and more.
The CBE Series 200 Valve Bagging Machines are used to fill valve bags to weight ranges of 10 to 110 pounds with powders, granules, or flaked products.
The operator installs an empty valve bag and manually clamps it down to the bag filling spout. The operator then presses the start button and material enters through the top of unit into a surge hopper. The hopper contains a spiral agitator that promotes the flow of the material into the auger. The auger then turns on and off from the command controller to fill the valve bag to a set point weight. The bag clamp is then released and the operator removes the filled valve bag from the bag chair.
A US lime producer needed to replace 2 brute force vibratory screens at their limestone quarry due to constant failure of the drive bearings, lost production time, and maintenance costs. After discussions with plant engineering, a single unit with a natural frequency drive screen was selected to process crushed limestone at a rate of 650 tons per hour.
