Saw Dust Loading Systems
Muza Sheet Metal Co. has been designing, fabricating, and installing Sawdust Loading Systems for years. Along with sawdust we transfer powder, metal, and various other dusts or partials. This increases production, reduces maintenance and clean-up and allows for collected materials to be recycled.
This works especially well in the wood dust industry where there is a high volume of wood dust and chips collected and the customer wished to either sell or transfer that product. Our systems take the product from the dust collectors to semi trailers. This in turn loads the semi trailers to be transferred off the customer’s site.
After waste materials are collected and transferred, various methods are used to load the waste into containers, trailers, boilers, storage bins, silos or to another manufacturing process. In low pressure air systems, rotary airlocks are used to drop material out of cyclones and filters. If many drop points are needed, screw conveyors can be added with motorized slide gates to distribute the waste. Design parameters similar to the ones used in conveying systems are also used in the engineering of Load-Out Systems. By determining the material characteristics, bulk density (lbs./ cub.ft.), volume capacity (lbs./hour), and desired feed rate, our project engineers can design the system most suitable to the customer’s needs.
Types of Waste Transfer Systems
A widely used, cost effective method to load-out waste into containers, hoppers, bins, silos, and trailers is with the use of screw conveyors. They are used to feed boilers and other equipment where a metered feed system is needed. Screws and augers are also incorporated into equipment specifically designed to unload silos and storage bins. Incline screw conveyors can then elevate the material to a point over an open-top trailer or other container. When the material is discharged into a trailer, a leveling screw can be added to distribute the waste evenly.
Trailer Blow-In Systems
A less expensive way to directly load waste material into a trailer is with the use of a low pressure blower system. A van trailer is parked and sealed at a “back-stop” where a positive pressure pipe blows waste into the trailer. A negative pressure pipe exits the trailer and travels back to the blower creating a close-loop. If any material does not settle in the trailer, it exits and loops back around.
