The center distance of the hammer crusher is expressed in meters.
In order to avoid the counteracting force when the hammer crusher is working, it is necessary to make the mounted hammer head on the hanging pin shaft to avoid the counteracting force. That is, the balance condition of the hammer head is sufficient so that the position of the hammer head in the hanging pin hole meets the requirements of the following formula :L=fc|j, the distance between the center of the hammer head and the hammer head of the hammer head, and meters; J - hammer head to the suspension center of the extremely inertia torch, meters; F - the area of the hammer head, and the distance from the center of the center of gravity to the center of gravity. According to the above calculation, the hammer head suspension and the strike center distance installation can basically eliminate the counteracting force on the pin shaft. But, in fact, the performance of the hammer head is more complex, because hit the center position has great randomness, the place such as hammer head and the shaft pin of wear may also affect balance condition and so on, and this in the above formula to reflect completely, so in practice should fully consider the impact of these factors.
Hammer crusher is used for crushing and abrasion weak material. The compressive strength of the material is no more than 100MPa, and the moisture content is less than 15%. The crushed material is coal, salt, baiya, gypsum, tile, limestone and so on. It is also used for breaking wood, paper or broken asbestos-cement to recover asbestos fibre, etc. The new type high efficiency hammer crusher has the absolute advantage in limestone crushing.
