Lower Tracking Kit - RTP 33

The RTP 33 Lower Tracking Kit from LFA Tablet Presses is an original spare part kit for your RTP 33 Rotary Tablet Press. Made from brass and designed to ware to avoid damaging your turret or tooling these part will need to be changed from time to time. The parts included in this kit are the Fill Cam, Ejection Cam and Dosing Cam

Fill Cam

The Fill Cam on the RTP 33 pulls down the lower punches to fill the Die Bores with powder. This part is built from brass and is designed to wear to protect the Tooling and the press. The main causes of a worn Fill Cam are:

• Tight lower punches due to buildup of excess fines in powder
• Use of incorrect Tooling with the wrong head profile
• Powder that mixes with oil/grease, which creates a sandpaper effect on the Fill Cam.

Before you order new fill cams for your rotary tablet press we suggest that you inspect your old ones. If they are ready to be replaced, there will be obvious signs of wear. Scrapes, scratches or discolouration in the surface can all be signs of your cams being out of tolerance.

Ejection Cam

The Ejection Cam for the RTP 33 Rotary Tablet Press ejects the tablets at the correct moment in the Turret's cycle. This part is not able to be tuned and is fixed in place. Over time this part can wear, and the tablet's ejection point can get lower until they are not ejecting correctly from the Die Bores. The three main causes of this are:

• Tight lower punches due to buildup of excess fines in powder
• High ejection forces that are caused by sticky powders clinging to the Die Bore's wall
• Powder that mixes with oil/grease, which creates a sandpaper effect on the Ejection Cam

If your tablets are not ejecting smoothly and there is obvious excessive ware to the ejection cam then it is time to replace it. This part is easy to replace requiring only 3 bolts to hold it in place.

Dosing Cam

The Dosing Cam on the RTP 33 is used to calibrate the press to produce the desired tablet weight. This is done by pushing excess powder out of the Die Bore after it has been filled. The main causes of a worn Dosing Cam are:

• Tight lower punches due to buildup of excess fines in powder
• Use of incorrect Tooling with the wrong head profile
• Powder that mixes with oil/grease, which creates a sandpaper effect on the Dosing Cam.

The signs of wear will include, inconsistent tablet weights and the inability to achieve smaller doses. You might also be able to see the ware on the cam it's self.
