Quiz Questions Preview
Question 1
Which of the following statements about multi-station rotary presses is true?
Explanation
Multi-station rotary presses enhance production efficiency by utilizing several tooling stations that compress the material simultaneously, allowing for higher output.
Question 2
Which component of the single punch tablet press is responsible for adjusting the weight of the tablet being produced?
Explanation
The tablet adjuster is specifically used to adjust the volume of powder fed into the die, which directly controls the weight of the resulting tablets.
Question 3
What is the primary function of a tablet press?
Explanation
The primary function of a tablet press is to compress powders into tablets of uniform size, shape, and weight.
Question 4
Which component of a single punch tablet press is responsible for holding the powder before compression?
Explanation
The hopper is where the granules/powder mixtures are poured into before tableting or compression.
Question 5
In a single punch tablet press, which punch is static during the compression process?
Explanation
In a single punch tablet press, the lower punch is static while the upper punch exerts the compaction force.
Question 6
What are the three stages involved in the tablet production process?
Explanation
The tablet production process involves three stages: Filing, Compression, and Ejection.
Question 7
Which type of tablet press is also known as an eccentric press?
Explanation
The single punch tablet press is also referred to as an eccentric press due to its mechanism.
Question 8
The die cavity in a tablet press primarily determines which of the following characteristics?
Explanation
The die cavity determines the diameter, size, and to some extent, the thickness of the tablet.
Question 9
What is a significant advantage of the single punch tablet press compared to other types?
Explanation
A significant advantage of the single punch press is its ability to manufacture odd-shaped products.
Question 10
What is the role of the ejection adjuster in a tablet press?
Explanation
The ejection adjuster facilitates the ejection of the compressed tablet from the die cavity.
Question 11
Which type of tablet press has multiple tooling stations?
Explanation
The multi-station press has several tooling stations designed to increase the output of tablets.
Question 12
In which stage of tablet formation do the powder granules become compacted?
Explanation
During the compression stage, the powder granules are compacted into tablets.
Question 13
What is the function of the cam truck in a tablet press?
Explanation
The cam truck guides the position and movement of the punches during the tablet formation process.
Question 14
What kind of pressure does a single punch tablet press utilize?
Explanation
Single punch tablet presses utilize high pressure to control weight variations between tablets.
Question 15
Which of the following best describes the compression process in a tablet press?
Explanation
The compression process reduces the porosity of die content, forcing particles into close contact.
Question 16
How does the production speed of a single punch tablet press compare to a rotary press?
Explanation
Single punch tablet presses produce approximately 60-85 tablets per minute, which is slower than rotary presses.
Question 17
What is a primary consideration when designing a tablet press for production?
Explanation
Speed, capacity, and efficiency are crucial design considerations for tablet presses to ensure effective production.
Question 18
In a rotary tablet press, what is the advantage of applying compaction force through both punches?
Explanation
Applying compaction force through both punches in a rotary press increases uniformity and consistency in tablet production.
Question 19
What is the main benefit of using a rotary tablet press over a single punch press?
Explanation
Rotary tablet presses are designed to increase production output compared to single punch presses.
Question 20
What is the primary function of the upper punch in a single punch tablet press?
Explanation
The upper punch is responsible for compressing the powder in the die cavity to form a tablet, while the lower punch remains static during the compression process.
