Safety Points While Operating the Grinding Machine

It is prohibited to open the operating gate until the grinding machine has been fully stopped; the safety mechanism of the access door is equipped with a locking cylinder for prevention of opening and a proximity switch for prevention of starting up after the door is opened. Do connect the electric circuit and air piping as required, ensuring that the cylinder locks the access door when the equipment is running, and the door cannot be opened until the equipment is stopped absolutely, and the equipment cannot be started up when the access door is opened.

It is forbidden to approach the rotating components by finger during running of the grinding machinery. The inspection, maintenance and cleaning work can only be done after the pulverizer rotor has been completely stopped.

If the coupling bolts between the convex cover and the grinding chamber and between the discharge outlet and the air pipe are not removed, do not pull the handle of the manual hydraulic pump so as to avoid any damages of the equipment.

When choosing the grinding machines with a hydraulic opening mechanism, it is a must to ensure there is no leakage at joints of each pipe, to avoid any danger due to pressure loss during operation. Customers should not adjust the guiding counterbalance valve at will, so as to avoid possible dangers.

When using the hydraulic opening mechanism to open the top cover for repair, do not turn the unloading valve of the manual pump at will, so as to avoid personal injury resulted from falling of the top cover.

Before power cut-off, do not open the junction box of the motor, so as to avoid personal injury resulted from electric shock. Set the rotating direction for the motor strictly according to the rotation direction indicating mark, so as to avoid any damages of the equipment.

Prevent tramp metals or other foreign sundries from entering the grinding chamber, so as to avoid any damages to the hammer blades and geared rings.

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).
