1. The center feeding falls with the material: the material enters the crusher through the feed hopper, and the material cone falls to the powder tray, and is divided into two parts by the powder feeding tray. A part of the bulk material by the middle of the plate into the high-speed rotation of the impeller, the impeller is quickly accelerated, then high speed  out from the impeller, with the bulk of another part of the material under impact plate scattered around the broken, and then together to impact crushing cavity lining materials, by oblique impact to rebound at the top of the crushing chamber, downward movement to change direction, and emitted from the impeller material to form a continuous material screen. Thus, the material is broken, rubbed and ground in the crushing chamber for crushing purposes. The crushing material will leave the crushing chamber under the action of gravity and unload in the unloading hopper of the lower casing. The wall of the crushing chamber is provided with an upper and a lower protecting plate, so as to protect the casing from being impacted and worn. This is the “rock stone”; if the strike plate for a week under the shield, the materials is directly impacted by the week on the guard plate and broken, this is the center of the feed “hot stone”.

2. Center feed and center feed with waterfall down the working principle of material is basically the same, the difference is the center when the feed will be cone removed, all materials from the feeding port directly into the bulk material plate, scattered by the tray and then broken impeller directly into the middle.
