The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large of an angle causes boiling in the crushing chamber. This is where the jaw plates cannot grip onto the rock, and it keeps slipping up and down, avoiding being crushed.
Hammer mills and impact crushers. One of the most versatile crushers available, hammer mills and impactors can be primary, secondary, and tertiary crushers. Hammer mill crushers use continuous hammer blows to shatter and disintegrate material. They are typically horizontal rotating in an enclosed cylinder casing. The hammers are attached to …

The hammerhead wearing grade is a classification method to indicate the hammerhead metal wearing conditions of a hammer crusher. According to this standard, the hammerhead wear is determined and divided into three grades, 1, 2 and 3. Grade 1 indicates the smallest amount of wear, while grade 3 indicates the largest amount of wear.
