Lesson 09 – Tablet Compression Copy

Question 1 of 10

1. Question

Mechanical (paddle) and gravity style feeders are designed to guide powder into the dies to achieve

To over-fill the die with blended ingredients
To under-fill the die with blended ingredients
To reduce the flow of the blended ingredients
Feeders are designed to blend ingredients a little more before filling the dies.

Question 2 of 10

2. Question

Pre-compression is defined as a way to

De-aerates and extends dwell time
Improves weight control
Improves tablet ejection
Controls the machine speed

Question 3 of 10

3. Question

The Weight/Dosing station

Pushes the excess overfilled ingredients to archive achieve the proper volume of fill, which is equal to the actual final tablet weight.
Has high speed check-weighing scales that are designed to adjust the volume each die
This is an optional device that isn’t needed to make a good tablet
This is a fixed adjustment that is pre-set and should never be changed by the operating technician

Question 4 of 10

4. Question

A scraper blade is designed to function as follows:

The scraper is spring loaded so that it scrapes the die table cleanly to assure accurate volumetric die fill.
The scraper blade should always be set with a clearance to allow excess powders to flow under it
The scraper blade helps remove air from between the particles
The scraper blade only needs to be used during the cleaning process.

Question 5 of 10

5. Question

Final compression is performed under the following device

The main compression upper and lower pressure rolls
The pre-compression upper and lower pressure rolls
The ejection cam
The upper raising cam

Question 6 of 10

6. Question

Tablet hardness variations can occur from

Weight, thickness, machine speed, punch penetration and pre-compression
The length of the upper raising cam
The speed of the lower pressure roll
Only from the speed of the paddles in the feeder

Question 7 of 10

7. Question

Tablets may break-apart during ejection for all the following reasons except

Machine speed, and the take-off blade position
Compression force and die wall ID ( inside diameter) condition
Variations in Over-all lower punch length and the amount of lubricant in the formula
Too many Upper punches

Question 8 of 10

8. Question

The most important tablet attribute is:

Tablet Weight
Tablet Thickness
Tablet Hardness
Tablet Friability

Question 9 of 10

9. Question

As the tablet press speed increases, tablet hardness will typically

Decreases and get softer
Increase and get harder
Will not change
Will only effect disintegration

Question 10 of 10

10. Question

Some rotary press turrets turn clockwise and some turn counterclockwise

True
False
