AQL defects during compression stage

(ankit kumrawat) #1

What is the possible reasons for black particles/spots in compressed tablets? And can we minimise it.

  1. Material problem (product itself)
  2. Machine problem (lubricants, oils)/ gasket shredding
  3. Accesories equipment problem
  4. Process generated- through attrition with machine parts
  5. During the process- due charring.
