Tablet press common problems and solutions

Now many enterprise tablet press is the lack of care, usual time employees are all busy with production and neglect the maintenance of the machine. So ordinary machine problems because of a little trouble, and cause the machine service life, today Jin Zong medicine machine small make up several tablet press share common problems and processing methods: 1 particle distribution uneven thickness, pressure were different particle velocity, which results in the pack to the particle thickness uneven inside the die hole, such as coarse particle more amount of light, the fine particles is more heavy. Solution: should will go to too much powder particles blending or screen. 2 if there is a fine powder adhesive punch and cause hanging when rushing can make the weight range is larger. Down at this time the rotation is not flexible, should be timely check, remove the punching die, clean up the stamping and die. 3 particles liquidity is not good, when the amount of particles flow into the die in waxing, caused by excessive weight difference and overrun. Solution: should resume granulating or join a suitable flow aid such as micro powder, silica gel, improve particles liquidity. 4 particle stratification. Solve the granular layer, reduce the granularity is poor. 5 of the smaller tablets materials choose larger particles. The solution: selecting the appropriate size of particles. 6 hopper blocked, this kind of phenomenon often occurred in wet sex strong sticky or drugs. Should increase hopper dredge, keep the tablet environment is dry, and appropriate to join the flow of aid to solve. 7 large difference of material in the material storage and control within 50%. 8 feeder imbalance or not installed in place, causing uneven packing. 9 scraping powder plate uneven or bad installation. The solution: leveling. 10 take forced feeder, forced feeder dial wheel speed and rotary speed does not match. The solution: the consistent. 11 anastomotic punch and the die hole is bad, such as down under the peripheral leakage between the die wall more powder, the 'dry' occur down, causing insufficient filling materials, and this should replace the punch and die. Under 12 different length and super bad, cause uneven filling quantity. Solution: repair the poor, poor within + / - 5 microns. Thirteen zone of damping, damping screw adjust the damping force of the poor. To readjust. 14 rail wear or filling filling mechanism is not stable. Solution: replace or solid. 15 for production, rotary speed too fast, filling quantity shortage. Especially when large pressure, due to lower speed, to ensure adequate filling. 16 tablet machine vibration is too large, loose structure, unreasonable assembly or repackaging; Tablet press set pressure and reduce the pressure.
