Questions Asked in Disintegration Feeder Operation Interview
Q 1. Explain the principle of operation of a disintegration feeder.
A disintegration feeder, also known as a primary crusher or pre-crusher, is a piece of equipment designed to reduce the size of large, bulky material before it enters subsequent processing stages. Its principle of operation relies on the controlled application of force to break down the material. This force can be achieved through various methods, including impact, shear, compression, or a combination thereof. The material is fed into the disintegration chamber where the breaking action occurs. The reduced size material is then discharged from the feeder. Imagine a rock crusher – it takes large rocks and breaks them into smaller pieces; that’s the core principle at play.
The key is controlled reduction. We don’t want to pulverize everything instantly; instead, we aim for a specific size distribution suitable for the next stage of the process, whether it’s milling, grinding, or further processing. This controlled size reduction improves efficiency and reduces wear and tear on downstream equipment.
Q 2. Describe the different types of disintegration feeders.
Disintegration feeders come in various designs, each tailored to specific material properties and processing needs. Some common types include:
- Hammer mills: These use rapidly rotating hammers to impact and shatter material. They are effective for brittle materials.
- Jaw crushers: Employing a reciprocating jaw mechanism to compress and crush the feed. They are robust and handle tough materials well.
- Cone crushers: These use a rotating cone to crush material between the cone and a stationary mantle. They are known for their high capacity and relatively fine product size.
- Roll crushers: Utilize two counter-rotating rolls to squeeze and crush material. Suitable for materials that are not extremely hard or abrasive.
- Impact crushers: Employ high-velocity impact to break the material. These are effective for a wide variety of materials.
The choice of disintegration feeder depends on factors like material hardness, moisture content, desired output size, throughput requirements, and budget constraints. For example, a hammer mill might be suitable for relatively soft materials like coal, while a jaw crusher would be better suited for hard rocks.
Q 3. What are the common causes of jams in a disintegration feeder?
Jams in disintegration feeders are a common operational headache. Several factors can contribute to these disruptions:
