Bins and Bin Systems are the industry standard for powder handling applications where close containment is required. Custom Powder Systems Bins and Bin Systems are used in virtually all powder handling and processing applications, and will be custom designed to meet your specific requirements.
- Close containment
- Ease of cleaning
- Off-line storage and testing
- Quick batch changeover
- Repeatable, homogenous blending
- Modular design for ease of transport and versatility
Custom Powder Bin Standards
The basic design of our bins meets most GMPS and “UN” codes withstanding drop tests, vibration and lifting test as well as design pressure test described in “UN” and DOT standards.
Aluminum 5052-H34 alloy, .125 thick top, shell and hopper. Legs and fork channels are from .250 thick materials. All material finishes are 2B mill finish on both sheet sides.
- Product contact welds, freehand buffed clean removing major weld smoke and splatter.
- Product contact welds, sweat welding by reheating the weld with the torch while not adding additional weld rod, smoothing the weld.
- Product contact welds, grind flush and polish with 80 grit to 40 – 80 RA.
- Product contact welds, grind flush and polish with 150 grit to 15 – 30 RA.
- Product contact welds, grind flush and polish with 320 grit to 10 – 20 RA.
- Product contact welds, mask off the area to be buffed and strip buff clean, removing major weld smoke and splatter.
- Non product contact welds, grind flush and polish with 80 grit to 40 – 80 RA
- Non product contact welds, grind flush and polish with 150 grit to 15 – 30 RA
- Non product contact welds, grind flush and polish with 320 grit to 10 – 20 RA
- Non product contact welds, mask off the area to be buffed and strip buff clean removing major weld smoke and splatter.
- Formed angle legs with bottom leg pads and welding to the body sheet.
- Tubular legs made from 4” diameter material.
- 5 ½” tall by 4 ¼” x 6 5/8 fabricated leg designed to fit the contour of the bin bottom.
Transitions from rectangular bin body to 12” diameter outlet with a 60 degree slope on the longest base side. Outlet of hopper has a ½” thick flange to mate with the valve. For added strength and appearance the top of the transition is formed up to allow a flat butt weld to the bin body.
Discharge valve is 12” nominal size butterfly valve. The seat and seals are White Nitrile. The seal design encapsulates the valve body and is also the seal between the flanges. The valve disc and body is polished Stainless Steel. The valve handle is designed with a full open detent and a full closed detent. The valve is designed for use on portable bins and the disc is machined to hold approximately 12 PSI to make manual operation easier.
The discharge valve operation is automatic using a handle with adapter mating with an adapter on the discharge station. When mated the valve can be opened and closed with a pneumatic actuator.
Nominal 22” diameter drum cover style top opening. Stainless Steel flat raised center design. Bolted and plated clamp ring operation. Gasket is white Sanoprene and stretches around opening before lid is attached (removable for ease of cleaning or replacement).
Top & Corners:
Top is a one piece formed design. Shell and top corners have a large 2” radius for ease of cleaning.
Stacking & Lifting:
4 corner combination leg positioners for stacking and lifting lugs for overhead handling are provided from ¼” thick material.
Custom Powder Systems attaches a data tag to each bin with a model number and serial number. References to these numbers identify the work order and drawing number on file with the company.
History of the IBC
The original IBC was made in 1937 from plywood in the Seattle area for the storage and handling of flour for the flour milling industry in the area. After WWII the originators got in touch with Beatrice Steel Tank in Nebraska, formed a partnership and named the new company “TOTE System”. The first metal containers where made from aluminum in 1948. The design was for a side door unit which allowed for the discharge of almost any powder including those with poor flow characteristics.
A discharge station called a pivoted hopper discharge was designed to match the bin’s door area and was used for 2-3 years. A new tilting discharge hopper was designed which improved the sealing and dust control. The tilting discharge or stationary hopper was used for many years and worked very well until the bins became dented and worn making them hard to seal.
Bottom discharge units where designed that used a transition hopper from the rectangular body down to a discharge valve. This design eliminated the problem of dust control and allowed for the discharge to close against the flow of product.
