Analytical RDF Rod Making Machine: How to Turn Waste into Practical Fuel

1).Definition of RDF rod making machine

RDF (Refuse-Derived Fuel) is refuse-derived fuel. RDF rod making machine is a device that processes recyclable waste (such as plastic, paper, sawdust, etc.) into fuel with a certain shape (usually rod-shaped). These RDF rods can be used as alternative fuels in industrial boilers, power plants, etc., to achieve resource utilization of waste.

2).Working principle and use steps of RDF rod making machine

1.Raw material preparation

First, collect suitable raw materials. For example, for raw materials containing plastic, make sure they are relatively clean and do not have too much impurities such as soil, metal, etc. Because impurities may damage the parts of the rod making machine. If it is wood chip raw material, its humidity should be controlled within a certain range, and the moisture content is generally recommended to be around 12% - 20%. Too wet sawdust will make molding difficult, while too dry sawdust may produce too much dust during the pressing process.

2.Crushing stage (if the raw material size is large)

Many RDF raw materials need to be crushed before entering the rod making machine. For example, if waste wooden furniture is to be made into RDF rods, it needs to be turned into smaller wood chips by a crusher first. This process makes the raw materials easier for subsequent compression and molding operations.

3.Conveying raw materials to the rod making machine

Use a conveyor belt or a screw conveyor to convey the prepared raw materials to the feed port of the rod making machine. During the conveying process, ensure that the supply speed of the raw materials is relatively stable. If the feed speed is too fast, it may cause blockage inside the rod making machine; if the feed speed is too slow, it will affect production efficiency.

4.Molding process

After the raw materials enter the rod making machine, they are pressed by the screw propeller or pressure roller inside the rod making machine. Taking the screw propeller rod making machine as an example, the screw propeller will continuously squeeze the raw materials forward, and under the action of the mold, the raw materials are gradually compressed into a rod shape. During this process, the temperature inside the rod making machine will also rise due to factors such as friction between the raw materials, which helps soften and mold some raw materials (such as plastics). The shape and size of the mold determine the final shape and size of the RDF rod. Generally, the diameter of the common RDF rod is between 30 and 80 mm.

5.Cooling and collection

1.The newly formed RDF rods are hot and soft. They need to be cooled by a cooling device (such as natural air cooling or water cooling) to harden them for easy collection and storage. The cooled RDF rods can be collected into a special container or conveyor belt through the discharge port, and then packaged or transported directly to the place of use.

2.When using the RDF rod making machine, the operator needs to strictly follow the instruction manual of the equipment and pay attention to safety, such as preventing the hands from being caught in the feed port or other moving parts. At the same time, the rod making machine should be regularly maintained and serviced to check whether the various parts of the machine are normal, such as whether the mold is worn and whether the screw propeller is loose.
