How to solve the powder leakage of the tablet press

High-speed tablet press machine(with a forced feeder). During batch compression, it is found that the powder-feeding device is in contact with the large plate and the powder leakage is serious. How can I solve it?

     It is estimated that the platform under the powder-feeding device is not flat with the large plate, coupled with a certain amount of pressure during the tableting process, the particles have better fluidity and less fine powder. The level of the platform and the large plate is adjusted, and the powder is still leaking. solve?

　　 Why is there a serious leakage of powder when there is less fine powder? Is the size of the particles relatively small? We use the rocking granule mechanism to compress the tablets, and there is basically no problem of powder leakage. The high-speed tablet machine machine guesses that if the granulation is fluidized bed granulation, the particles themselves will be small, and this phenomenon will occur.

Check the manual of the tablet press machine you purchased. The above will indicate the amount of fine powder that the device can accept (usually 100 mesh is the fine powder). If your variety exceeds this amount after granulation, it means that the equipment is not selected. If you choose it, you can only improve the process or change the equipment; if it meets the particle requirements of the equipment, then it is a problem with the equipment. Generally speaking, the turntable of domestic equipment (that is, the large plate) will have a difference in height due to the processing technology. In contact with the feeder, there is indeed a large gap in the other part. This is one of the main gaps with the tablet presses such as Ima and Fit Bosch. In this case, there is really no good way.

　　The process of direct compression, the diameter of the material is 90% of the 40 mesh, and the main problem is the gap.
