Both the reversible hammer crusher and the ring hammer crusher are commonly used crushing equipment in electric coal crushing, coal washing plants and other common crushing models. Toothed roller crushers are also commonly used in the field of coal gangue crushing, but they are coarse crushers. What is the difference between the reversible hammer crusher and the ring hammer crusher as common fine crushing equipment in the coal crushing field?
The first is that the machine structure is different. The ring hammer and tooth hammer used in the ring hammer crusher, and the alloy hammer head of the type used in the reversible hammer crusher with the hammer head and the hammer handle separated. Its typical feature is that it can be reversed and reversed after the hammer head is worn. Save half of the maintenance time.
Another big difference is that the reversible hammer crusher has no plate device. The discharge adjustment depends on the gap adjustment between the hammer head and the impact plate, so materials with a water content of more than 10% and less than 15% will not be blocked. The ring hammer crusher has a pen board at the bottom of the discharge, which cannot crush materials with large water content.
The adjustment of the discharge fineness of the ring hammer crusher depends on the size of the screen hole of the bottom grate plate. The advantage of ring hammer crushing is that the output is large, and the inertia of the rotor is used to crush, and the throughput is large. But it can only crush softer materials. The reversible hammer crusher can crush harder materials. After the hammer head is improved, more are used in the machine-made sand production line.
