The GPM series RDF forming machine is a solid waste terminal resource utilization equipment developed by GEP, which combines the advantages of similar products. The original design of pressing wheel, module, anti stuffiness machine, full-automatic oil pump, etc., makes it have the advantages of reasonable structure, high production efficiency, low energy consumption, strong adaptability, simple operation, reliable performance, easy movement, etc., so it is widely used in the production line for resource disposal of industrial leftovers in shoe clothing processing plants, paper scum, domestic garbage, agricultural and forestry waste and other raw materials generated in the processing of Paper mill. The RDF fuel produced is in granular form, with a diameter of 30mm and a length of about 50mm. Its moisture content is controlled at around 13%, and its heat generation is close to that of coal, making it easy to store. It is popular among garbage power plants and cement plants.
Structural Composition
The RDF forming machine is composed of a frame, an electric motor, a feeding port, a transmission system, a pressure roller, a ring mold, an electric heating ring, a discharge port, and other parts.
Operational Principle
The forming molds are tightly arranged in a circular layout, forming a material forming channel between two adjacent molds. In this way, the entire machine forms a radial distribution of material forming channels. The forming press wheel performs planetary motion under the driving force, driving the material to be fed into the mold inlet. As the pressure roller gradually approaches the point of cutting into the mold, the fed material is squeezed into the mold channel under the normal pressure of the pressure roller, and continues to stack within the channel to form pressure. Finally, it exits the mold as a finished product and completes the entire forming process.
Requirements for Raw Materials
The raw materials shall not be mixed with substances such as soil, sand, stones, metals, etc. to ensure the quality of the finished product and the safety of the use of molds and rollers; The length of raw material crushing should be controlled within the range of 50mm~80mm to ensure the minimum resistance between the machine and the module during production, reduce reactive power loss, and increase production yield; When inputting raw materials, it is necessary to continuously maintain a constant amount and mix evenly to ensure smooth machine operation.
Fault and Handling
The main machine is blocked | 1. The material has low water content 2. Excessive supply, resulting in overload 3. Entering hard objects such as iron blocks 4. The module and pressure wheel are severely worn, causing difficulty in discharging. | 1. Adjust the moisture content of the raw material at any time according to the density of the pressure block 2. Reduce supply 3. Remove hard objects such as iron blocks 4. Adjust the clearance, repair or replace the module and pressure roller |
The discharge hole does not discharge | 1. The discharge hole is blocked 2. Improper module gap | 1. Clean the materials in the mold 2. Adjust the gap, repair or replace the module |
The finished product does not form blocks | The moisture content of the raw material is too high, and the aging reaction time is short | Adjust the moisture content of the raw material, increase the aging reaction time, and have at least three types of moisture content for debugging |
