Pelleting pellet machine upkeep and maintenance - pellet mill - the pharmaceutical industries

Granulator As the production of important equipment, its use and maintenance, maintenance is especially critical. Here's what Granulator use and upkeep, upkeep.

1, that mixed the general work approach

Silo - feed screw - Conditioner - granulating pellet machine - cooler - finished warehouse.

2, granulating approach for attention

1. Material inside the granulation need to undergo a conditioning, steam stress would be to stabilize (4-8bar), as well as the steam prior to the transfer must be in addition to water good quality, if the steam contains a great deal of water, will trigger granulation on the plug. Components after conditioning, there happen to be a certain degree of maturation, can significantly improve the utilization of feed nutrients.

2. Granulation approach, the components should constantly check the humidity and temperature. Humidity strategy to verify is: hand-Qing Nie, the material could be inside the piece as well. Species as a result of granulation temperature to differ, to stabilize the manage in 75? 95 in between.

3. After pelleting the particles need to not be excessive cooling or cooling just isn't sufficient, if cooled also rapidly, make material particle surface cracking, cool adequate, the temperature is as well higher, material will absorb moisture causing mold block. Right after cooling, the material must be constant with all the area temperature.

3, ring die and roller selection

1. Ring mold material is typically carbon steel, alloy steel or Stainless steel , In line with components corrosion and ring-mode intensity of operate to select the ring mode of the material, around the corrosion of components and a tiny ring mold hole generally use stainless steel ring mold. Roller material normally utilized within the carbon steel or alloy steel. Or concave kind tooth may be used for Pass.

2. Ring die compression ratio. Ring mold ring mold compression ratio may be the powerful operating length and die diameter ratio. Raw supplies and goods according to specifications formula to pick the ring mode from the compression ratio. Low compression ratio can increase production, minimize power consumption, minimize the ring die and roller wear. Nevertheless, loose particles, of diverse lengths, feed powder rate; contrary particle solid, smooth and shiny look, chalking little, but high production expenses. Users can decide on in line with their needs than the compression ring mold, animal pellet compression ring mold normally much less than ten, the ring die pellet feed aquatic compression ratio more than ten.

Model for some little holes in the ring, ring mold to make sure the strength on the premise of guaranteeing a reasonable compression, rising the thickness of the ring mold and decompression of much more accurate holes.

4, the appropriate operation, maintenance pellet mill

1. Ring die and roller gap adjustment ring for the new model and adjust the roller gap, the ring mold and ought to be the highest roller slight contact roller to attain "may transfer non-transfer" state. If adjustments inside the operate of state, might be acceptable ring mode and increasing the pressure roller, but undoubtedly sufficient is adequate. Ring die and roller gap is as well massive, pressure roller can not rotate, resulting in blocking pellet machine. Ring die and roller gap is as well little, will enhance the ring die and roller wear, load up, a severe cause ring die and roller harm. Need to promptly verify the ring mold and roller gaps, at least verify as soon as every four operating hours. When adjusting the numerous rollers, spend consideration towards the path of each and every roller adjustment need to be made relative towards the pellet mill roller shaft torque and zero, in order that pellet mill in the asymmetry of power.

2. Frequency of group upkeep Granulator every single class should be carried out before the inspection, verify the transmission elements, instruments, Valve Doors, raises oil (Jg with lithium lubricants), and take away iron on iron filings.

3. Appropriately installed or replace the ring die and roller is really a new model with all the new basic roll, roll the old model with all the old, in an effort to ring die and roller profiling state close towards the surface shape, ring die and roller of all equivalent nearby space . To ensure that the entire force, as well as a ring mold material are very uniform, can enhance production efficiency.
