Single-stand Vs Double-stand crumbler
What operational advantages does a double-stand crumbler offer compared to a single-stand unit in terms of throughput and product consistency?l

The only operational advantage I can think of is that a double stand may allow for larger pellets to be produced thus increasing feed production – with the double stand the top pair would be set to provide a slightly reduced size, with the second pair set to complete the reduction to the desired finished size. If using a single pair crumbler the rolls must be adjusted to accepted the pellets without grinding them, which leads to fines generation, thus you may need to use a smaller diameter pellet die which will reduce feed production per hour. Also the need to change pellet dies leads to ‘down time’ resulting in decreased production rate.
