Introduce the working process of the dust removal ash briquetting machine. When the dust removal ash briquetting machine is working, the materials must be effectively fed into the equipment. By pressing the rollers, the finished balls will fall off and be transported to the in-process warehouse through the conveyor. Common powder material filling methods include falling method, inhalation method, upper filling method, and lower filling method. Falling method: This is a more traditional method. The material is transported to the inlet of the dust removal pellet press through a box feeder, and the mixed powdery material is automatically fed into the equipment in a free fall manner. This method is used to fill the pellet. When powder is used, the filling speed and uniformity often depend on the cross-sectional area of the mold cavity and the speed of the powder. Inhalation method: Since the particle size of the powder used is generally between 40 and 200 μm, if the drop method is used, when the mold cavity is narrow, the powder will not enter easily and the speed will be slow, which will affect the efficiency of the forming machine. To improve this phenomenon, inhalation can be used. That is to say, when the powder filling box reaches the top of the mold cavity, the middle mold moves upward. This action causes the phenomenon of vacuum powder suction, which can speed up the powder entering between the rollers and ensure the completeness of filling. It is very helpful for filling materials with complex shapes and sharp corners, or thin-walled materials less than 1mm.
Filling method on the dust removal briquette machine: After the powder is filled into the pair of rollers, it is moved upward to the height of the mold surface. This is also very helpful for thin-walled parts, because the gap between the mandrel and the middle mold is small when forming thin-walled parts. It is easy to produce bridging phenomenon, which prevents subsequent powder from falling in. If the mandrel is first at the bottom, the roller space of the dust removal and briquetting machine can be increased to facilitate filling. After the filling is completed, these problems can be improved by moving it upward. Filling method under the dust removal ball press: After filling is completed, the middle mold moves upward again so that the powder moves downward relative to the mold surface. This prevents the powder from spraying outward when the upper punch moves downward and reaches the middle, and can reduce the Because the middle mold has a push-out angle or an arc angle, some powder gets stuck between the upper punch and the middle mold, causing powder pinching.
