When the tablet press produces tablets, a large amount of dust is generated in the tablet press chamber, which increases the resistance when the upper and lower punches are running, causes damage to the upper and lower guide rails, wears the punch tail, and dust enters the electric cabinet to cause electrical failure. We can analyze the problem from the working principle, the parts that generate dust during the tableting process and the cause, which can reduce the dust pollution. There are four reasons why the tablet press produces dust:

(1) Dust generated during manual feeding.

(2) During the upper punching process, the equipment operates normally, and the dust generated by long-term operation will enter the electrical cabinet and cause electrical failure.

(3) Under the normal operation of the equipment, the dust generated during the tablet punching process of the medical tablet press is inhaled by the powder suction port, but a certain amount of dust will still adhere to the bottom of the middle mold and the lower punch. The lower punching hole enters the guide rail of the lower die, and is mixed with lubricating oil to form mud. If it is not cleaned for a long time, it will pollute the environment of the tablet pressing room.

(4) The fine powder leaked from the feeder of the tablet machine during normal operation will follow the rotation of the turntable and enter the lower rail through the gap between the turntable and the platen, and the inhaled dust will dry up the lubricating oil, causing The wear of the lower rail guide and the lower rail guide reduces the service life of the guide rail.
