The vibratory separator is mainly used for the classification of spherical solder powder (3A grade spherical solder powder ) and the screen is generally composed of two layers: the upper layer of screen with 325 meshes and the lower layer of screen with 500 meshes. The powder screened by screen with between 325 and 500 meshes is the required product. In the early stage of putting the screen machine into use, the working effect has been not ideal because of the main problems of easily torn screen, high blocking rate for screen hole , difficulty to clear the screen and low screening efficiency.
In view of these problems above, we have made a reason analysis of the characteristics and use of the sieve machine's own structure, the main reasons are below:
a. Insufficient or uneven tensioning of the screen.
b. The vibration motor is not steering correctly.
c. Material accumulation.
d. Containing a large number of particles close to the separation point.
Improvement measure The main disadvantages of changing adhesive bonding technology of the screen are as follows:
a．At least two operators are required to press or demount the heavy screen vertically onto or off the grid.
b．Inconvenient operation. The edge of the screen frame should be vertically aligned with the edge of the grid. The strength should not be too large or too small, otherwise it will cause the crease of the screen.
e. Material's spherical particles producing static electricity or agglomeration causing the serious clog of the mesh.
Improvement measure
The main disadvantages of changing adhesive bonding technology of the screen are as follows:
a．At least two operators are required to press or demount the heavy screen vertically onto or off the grid.
b．Inconvenient operation. The edge of the screen frame should be vertically aligned with the edge of the grid. The strength should not be too large or too small, otherwise it will cause the crease of the screen.
In addition, the force should be uniform along the periphery of the mesh otherwise the loose part would pile up easily in the process of use for the uniform tension of the screen . Moreover, the screen mesh would tear easily due to the uneven stress on the whole screen surface therefore it is necessary to improve the paste technology of the screen mesh. After the improvement, the labor intensity ,in the bonding process of the screen, would be reduced so great that one person can set the hoop on the grid. Furthermore, the tensioning of the screen mesh is also so flexible that the strength of the screen mesh can be adjusted by the hoop bolt beside the tensioning of the screen is also uniform.
Changing the way to clean the screen
The vibratory separator mainly depends on the constant beating of the elastic balls to prevent materials from blocking the mesh in order to clean the mesh. However, in the process, the blocking of the screen holes are particularly serious, which shows that this scheme is not effective, and the bounce height and strength of the balls are not easy to control so that they would produce the damage to the screen. After the study, the ultrasonic vibration was used to replace the elastic ball to clean the screen, which is the organic combination of the ultrasonic generator, ultrasonic transducer and vibrating screen.
