When it comes to the working principle of a sand making machine, there are two key aspects: material feeding and the sand-making process.
In summary, a sand making machine crushes and grinds the raw material into the desired size of sand particles by applying force and impact. This crushing and sand-making process can be adjusted according to specific application requirements to produce sand that meets particular specifications.
- Material Feeding:
- Raw Material: The working principle of a sand making machine revolves around processing raw materials such as rocks, ores, and mineral powders. The raw material should have a certain hardness and particle size.
- Feeding Method: The raw material is fed into the sand making machine through a vibrating feeder or a belt conveyor, among other methods. During the feeding process, the raw material is evenly distributed onto the feed opening of the sand making machine.
- Crushing/Sand-making Process:
- Crushing Chamber: Inside the sand making machine, there is a crushing chamber consisting of one or multiple rotors and stators. The rotor often comes with hammers or blades to apply impact or shear forces.
- Crushing Action: When the raw material enters the crushing chamber, the rotor starts to rotate, applying impact, compression, and crushing forces. The raw material is crushed into smaller particles between the high-speed rotating rotor and stator.
- Sand Generation: During the crushing process, the raw material particles undergo further fragmentation and grinding due to the high-speed impact and collisions between the particles and the rotor. Eventually, most of the raw material is crushed into the desired size of sand particles.
- Grading and Screening: In some sand making machines, there are grading screens installed to separate sands of different sizes. This helps to produce sand that meets specific size specifications.
In summary, a sand making machine crushes and grinds the raw material into the desired size of sand particles by applying force and impact. This crushing and sand-making process can be adjusted according to specific application requirements to produce sand that meets particular specifications.
