As a material forming equipment, the briquettes press is widely used in major factories. Everyone knows that in order to ensure the molding effect and production efficiency of materials, the parameters and quality of the briquetting machine must be considered, but the problem that is often overlooked is the requirements for materials. It is also necessary to meet the requirements of the quality. The following editors have sorted out the requirements for the materials of the briquetting machine for your reference.
- The requirements of the briquetting machine for the material
- Particle size of the material: The particle size of the material to be formed should be between 80 and 200 mesh, so as to ensure that the pores between the material particles are uniform, and the material is more compact and stronger after pressing.
- The purity of the material: the higher the purity of the material, the less chance of impurities in it, the longer the service life of the briquetting machine, and at the same time it can avoid the situation of virtual balls, thereby improving the production efficiency, otherwise the stones or metal particles in the material It may cause premature damage to the roller skin of the ball press.
- The ratio of raw materials: The ratio and composition of raw materials directly affect the molding quality of materials, especially dry powder materials, which need to be proportioned with binders before pressing to ensure that the material particles can be combined with each other and remove air.
- Humidity of materials: adding a certain amount of water can increase the ball formation rate of dry powder materials to a certain extent, but for materials that already contain a certain amount of water, although a larger water content can increase the ball formation rate, it does not. It will reduce the strength of the pellets and cannot meet the subsequent transportation and use requirements.
- Material supply before pressing: Whether it is dry powder material or wet powder material, in order to ensure the quality of molding, it is necessary to provide a uniform, continuous and stable material supply; too much material will cause the briquetting machine to eat too much material. Increase the burden on the motor, too little will cause a virtual ball into a ball.
- Pretreatment of materials before molding
It can be seen from the above content that the molding of materials is not only a matter of the briquetting machine equipment, but also the various requirements of the materials need to meet the molding requirements. Before entering the briquetting machine, what kind of pretreatment work does the material need to do?
- When the material enters the briquetting machine production line, the stones in it should be picked out first, and strong magnets should be used to remove the metal in the key position of the conveying equipment to prevent the stones and metal particles from damaging the subsequent crushing and briquetting machine equipment.
- Before the material is pressed, the particles should be crushed to the corresponding particle size by the crushing equipment, and then the appropriate particle size should be screened out by the screening machine, and those that do not meet the requirements should be returned to continue to be crushed.
- Before entering the briquetting machine, the crushed materials should also be mixed with binder or water in the mixer to meet the pressing requirements. After mixing, the screw feeding device is used to enter the briquetting machine uniformly and stably. to suppress.
What are the different points of attention when using the briquette machine at different stages?
The working environment of the ball press is harsh and the work intensity is high. There are different points of attention for the work of the ball press in different periods. Necessary maintenance and maintenance can prolong the service time and life of the ball press. Next, the editor will tell you about the different points of attention of the ball press at different stages.
- Test machine stage
Before the test machine, the relevant installation and preparation work must be done well. Plan and sort out the installation of the machine and the preparation of materials in advance. After starting the machine, it must be idling for a few minutes before loading. The significance of this process is to preheat the running-in of the machine. And if there is a problem, it can be fixed and solved in time. It is very troublesome and inconvenient to solve the problem after the material is loaded and produced. - Preparation before production
Check whether the circuit is connected normally and whether the raw materials are adequately prepared. In the case of lack of raw materials, the limited balls are unstable. Only by ensuring sufficient materials can ensure that the limited balls are robust and not easily broken. - Production stage
In the production process, the feeding time of materials must be adjusted. If the supply is insufficient, the pressed ball will be unstable, so when feeding the material, it should be determined according to the situation of the ball. The strength is better. If the strength is too small, the strength is not good. If it is too large, it will cause the motor to be bored, causing the motor to be overloaded, and it is easy to damage the motor or burn the motor. Time monitoring conveyor orientation is normal. When the conveyor orientation is abnormal, it is necessary to adjust the base support. If there is a deviation, it should be corrected in time. If it is to the left, the left side should be tightened, and if it is to the right, the right side should be tightened until it does not deviate. - After production
In the process of pressing the ball, there will be a lot of dust and other dirty substances. After use, it must be mechanically cleaned. Check whether the machine is faulty, such as whether the screws are loose, etc. In many cases, major faults are caused by small problems. Therefore, we must clean and test the equipment after production.
