<p>The hammer type crusher rotor is made of a stack of discs, with fixed stays at their centre on a driving shaft. Regularly, near their periphery, are fitted oscillating hammers (7). The discs (1) are made jointed and each has two diametrically opposed openings (8). Each is crossed by a support shaft (6) of the hammer and the openings are shaped to allow rotation of the hammers inside. A filling piece (9) is fitted inside an opening when it does not hold a hammer. It is of the same and fits the opening exactly.</p> |
