Rotary Tablet Press Maintenance and Spare Parts

Overload protection system

Overload Protection System Fault Analysis and Solution: The main reason of the frequent alarm is compression pressure overload or the pressure setting of overload protection spring is too small, the solution is to adjust the pressure hand wheel, reduce the pressure or increase the overload protection spring set pressure.

Gear box

Gear box is composed of a worm wheel, worm and the cabinet, the common fault analysis and solutions: gearbox oil leakage is mainly caused by the flange screws loosen or seal aging, the solution is to tighten the flange screws or replace the seal and sealant.

Electrical parts

(1) A few minutes after boot is down: mostly because of excessive pressure makes the overload, the pressure should be reduced, re-start.

(2) The oil pump does not oil or oil too much: oil pump do not oil so that the guide rail, punch and other parts are not lubricated, oil too much will pollute tablets, mostly the reason is because the drive parameter setting problem, reset the inverter parameters to adjust the oilling time.

(3) Auxiliary power is no power: mostly because of line problems, check the line resolved.

(4) Tachometer, counter does not display, key failure, the panel bad, bad axial fans, warning lights broken, bulb is broken, rectifier bridge burnout. Electrical component failure have line problems, must be inspected lines, electrical parts damaged must be replaced to solve.

Auxiliary section

The auxiliary part is the vacuum cleaner, the fault is mostly host connection or improper configuration, specific problems can be investigated to solve.

Rotary tablet press machine maintenance and spare parts

Failure of the rotary tablet machine appears in the use process, a considerable part because of maintenance caused by delay, maintenance should pay attention to the following aspects:

(1) The tableting chamber should timely clearance. Rotary tablet press after working hours, tableting interior will be full of fine powder of materials, the powder adheres to these tiny punch, punch hole and the hole in the mold, it will cause the plug punch, punch rotation is not flexible, noise, even weighing instability and other mechanical failures, such as broken punch, broke feeder and so on. So, in a rotary tablet press working process should be regularly cleared compression chamber, suggest at least once per shift.

(2) Periodic inspection and maintenance the work pieces which easy to wear. Guide rail, roller, tablet press punch dies and other wear parts should be checked or lubrication and maintenance, preventive maintenance of equipment.

(3) The purchase of spare parts. Punch dies, the mold top wire, bridge plate, feeder, rail assembly, the upper and lower press wheel and shaft and other parts, a certain amount of spare parts should be purchased based on the production situation, to prepare for emergencies.
