Adjustment on SFSP66K/A Series Paddy Husk Hammer Mill

SFSP paddy husk hammer mill is a special paddy husk grinding machine and used as associated equipment of the rice mill and used for grinding of other paddy husk concerned.

Adjustment of hammers: the hammer in rotor is arranged symmetrically. When installing the hammers, which must be arranged strictly according to requirements, the different weight of two groups of correspondent hammers must be not more than 2 g, two edges of hammer can be used for grinding. After two angles of hammer are worn, replace this hammer. In order to apply the hammer and sieve plate much better, it is proposed that the rotation direction of grinder rotor is changed once each shift for increase the service life of the hammer and sieve plate. When replacing the hammer mill, open the operating gate, loosen the handle of sieve keeping mechanism, put down the sieve keeping mechanism, loosen the bolts on upper sealing plate at two ends of grinder by inner hexagon spanner and screw driver, dismount the upper sealing plate, pull out the split pin on pin shaft, take out the pin shaft, and replace the hammer. After replacing, reassemble the split pin (in assembling split pin may be damaged, if damaged, it should be replaced), and assemble the upper sealing plate.

Adjustment of sieve plate: according to fineness requirement of ground materials, select the sieve plate with corresponding aperture. The sieve plate on the grinding machinery should be replaced timely if worn through or damaged, the sieve plate is set in from two sides and held down by hold -down mechanism.

Adjustment of gap between hammer and sieve: two sets of pin shaft holes are designed on rotor hammer frame plate, 4 groups each set. The arrangement radius of two sets of pin shaft holes is different on hammer frame plate, thus, one set among them used respectively will obtain 12mm and 10mm (ex -works 12mm) gap between hammer and sieve, which can meet the different grinding demand (generally, it is required that the gap between hammer and sieve should be processed based on ex-works gap, if find out the troubles such as sieve blockage and unstable electric current etc, or if higher demand for particle size, the 10mm gap between hammer and sieve should be processed).
