The speed of a sieving machine can vary depending on the type of machine and its specifications.
For throw-action sieving machines, the speed is typically measured in revolutions per minute (rpm) of the nozzle. The range of speed for these machines can be between 5 and 55 rpm. This speed is important as it affects the distribution of the sieving sample over the whole sieving surface and the acceleration of the particles in a vertical direction. The throw-action motion allows particles to carry out free rotations in the air and change their positions, potentially allowing larger particles to pass through smaller mesh widths if they change their direction.
On the other hand, for air jet sieving machines, the speed is not explicitly mentioned in the provided references. The operating principle of these machines is based on the use of an air jet that drags the fine particles through a sieve. The sieving range for these machines is typically between 5 to 10 to 4000 microns. The performance of air jet sieving machines is often considered to be extraordinary, making them essential for quality control processes in various industrial sectors.
In terms of the working principle of sieve shaker machines, these machines use a vibration motor to generate vertical vibrations that transmit through the vibrating plate to the screen frame. The material particles smaller than the aperture of the screen are sieved to the lower screen frame, allowing for the separation of different particle sizes. The speed of the vibration motor determines the intensity of vibrations, which in turn affects the sieving efficiency and accuracy.
Overall, the speed of a sieving machine can have a significant impact on the sieving process, including the distribution of the sieving sample, acceleration of particles, and separation of different particle sizes. It is important to consider the speed specifications of the specific sieving machine being used in order to optimize the sieving results and ensure reliable and repeatable outcomes.
