The clearance of the pressure roller and the ring mode is one of the important parameters adjusted during granulator operation. The adjustment process is also one of the important adjustment steps before granulator operation, and the reasonableness of the gap adjustment directly affects The performance of the granulator. The correct adjustment will enable granulator to get the maximum production and manufacturing cost, save product cost, and improve economic benefits.

In general, the rotation direction of the ring mold is a clockwise direction, such as the granulator with two pressure rollers, the maximum eccentricity of the left side pressure roller should be turned on when the pressure roller is started. The maximum eccentric convex side of the right side pressure roller is mounted on the upper left space of the ring mold, and the rightmost half of the ring mold is mounted; if it is equipped with a plurality of pressure roller granules, it should also be guaranteed as an eccentric regulating block edge. When the opposite direction of the mold is rotated, the pressure roller should move in a direction in contact with the ring die, otherwise the pressure roller is not installed correctly, and should be reinstated according to the above requirements.

The gap of the roller and the ring mold is generally 0.3 mm to 0.5 mm, and the outer surface of the pressure roller is usually made when adjusting. The inner surface of the ring mold is slightly contacted, and it is similar to that of the ring mold. Under normal circumstances, the clearance of the plurality of the mold is small, the two are large; the new pressure mold clearance is small, the old pressure mold gap is large, if the pressure roller and the ring die are too small, the pressure roller is The ring mold is easily wear, and the noise is large, it is, and the clearance is too difficult to produce difficulties.

However, the circularity of the ring and pressure rolls will generally be slightly deformed, and the maximum outer outside of the pressure roller is applied. The diameter is in contact with the minimum inner diameter of the ring mold, and the gap is still 0.3 mm to 0.5 mm. This adjustment is often referred to as a jumping contact adjustment. Additional radial force (impact load) and abnormal metallic friction occurred.

The rolling rolls, ring molds are installed by cantilever beams, and the effect of additional radio force, one It is the cantilever support rod shake, and the rotary roll is conveyed against the ring mold, so that the ring mode is subjected to periodic alternating stress, and the reticulation of the ring mold is loose, so that the screw of the fixed ring mold is subjected to shearing stress, long-term Under the effort, it causes shear breakage in the root of the screw. The second is that the extra radial force passes to the bearing through the pressure roller, although the bearing for supporting the pressure roller rotates with a cone column bearing to withstand a certain radial and axial load, but the bearing length time is prone to the bearing under normal load. Inner and outer rings, rollThe shaping deformation of the topical stress exceeding the material of the bead working surface failed to show the shape of the yield limit of the material, and the inner and outer ring of the bearing and the uneven uneven wear pits were significantly uneven, and once the shape of the shaped deformation fails, the bearing shirt torque increased, rotatedPrecision decline, such as the shape of the shaped deformation exceeds a certain value of the bearing temperature rapidly, the greases are scrateched, the bearing holder is deformed, and the bearing card is dead.Since the pressure roller bearing is rotation of the inner ring fixed outer ring, if additional impact load is pronounced, the incoming bearing holder will obviously discover the injuries.

The gap between the pressure roller and the ring mold not only affects the difficulty of the granulator, but also affects the granulator.The life of itself, during the granulator operation, frequent ring-mold fixed screw breakage and pressure roller bearing damage, in the case of no other obvious cause, generally ring-mold, the pressure roller is lost, the gap between the twoSmall.
