A plurality of lifting rods 29 are at the inner surface longitudinal extension (being understandable that in order to simplify accompanying drawing, only the lifting rod 29 of some is identified among Fig. 1) of outer wall 34.
The inward flange 33 of discharge end walls 28 partly defines central opening 36, passes the slurry of gudgeon and discharges grinder 20 by described central opening 36, and slurry discharge grinder 20 usefulness arrow B identify in Fig. 1.
In the prior art, grinder 20 also comprises the discharging terminal inner lining 38 that is assemblied on the discharge end walls 28, and discharge end walls 28 and discharging terminal inner lining 38 are along with the rotation of housing 22 is rotated around central axis 24.Discharging terminal inner lining 38 also comprises pulp lifter (Fig. 1 is not shown) usually, and pulp lifter is assemblied on the discharge end walls 28, and partly defines a plurality of chambers 40 between described pulp lifter.As known in the art, chamber 40 is covered with by sieving grid 42 and is used for the screening the pulp material, and when slurry flowed into chamber 40, the sieving grid only allowed the particle below the size of regulation to pass through.
Usually, charging 45 approximately occupy vome of shell bottom 1/3rd or still less, for housing, discharge end walls and discharging terminal inner lining are positioned on the housing and rotate, chamber moves flooding between (or partly flooding) state and the rise state, slurry flows under the influence of gravity into chamber at described floodage (or half floodage), and at described rise state, the slurry in each chamber is sent from described chamber under the gravity effect.As an example, the charging shown in Fig. 1 45 has the degree of depth " D ".
