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

Granulator As the production of important gear, its use and maintenance, upkeep is specifically crucial. Here's what Granulator use and upkeep, maintenance.

1, particular that mixed the basic perform approach

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

2, granulating process for focus 1. Material in the granulation have to undergo a conditioning, steam pressure would be to stabilize (4-8bar), as well as the steam ahead of the transfer must be as well as water quality, when the steam contains a whole lot of water, will result in granulation from the plug. Materials after conditioning, there have already been a certain degree of maturation, can substantially enhance the utilization of feed nutrients.

2. Granulation approach, the components need to constantly check the humidity and temperature. Humidity method to verify is: hand-Qing Nie, the material might be inside the piece also. Species as a result of granulation temperature to differ, to stabilize the handle in 75? 95 between.

3. After pelleting the particles have to not be excessive cooling or cooling just isn't adequate, if cooled also speedily, make material particle surface cracking, cool adequate, the temperature is too higher, material will absorb moisture causing mold block. Following cooling, the material need to be constant with all the area temperature.

3, ring die and roller selection

1. Ring mold material is normally carbon steel, alloy steel or Stainless steel , According to supplies corrosion and ring-mode intensity of operate to pick the ring mode from the material, on the corrosion of materials and a little ring mold hole typically use stainless steel ring mold. Roller material typically used inside the carbon steel or alloy steel. Or concave kind tooth might be employed for Pass.

2. Ring die compression ratio. Ring mold ring mold compression ratio is the powerful operating length and die diameter ratio. Raw materials and goods according to requirements formula to pick the ring mode from the compression ratio. Low compression ratio can improve production, lessen energy consumption, lessen the ring die and roller put on. Nevertheless, loose particles, of diverse lengths, feed powder price; contrary particle strong, smooth and shiny appearance, chalking modest, but high production fees. Customers can decide on in line with their requirements than the compression ring mold, animal pellet compression ring mold generally significantly less than ten, the ring die pellet feed aquatic compression ratio greater than ten.

Model for some little holes inside the ring, ring mold to make sure the strength on the premise of making certain a affordable compression, increasing the thickness of the ring mold and decompression of much more precise holes.

4, the appropriate operation, upkeep pellet mill

1. Ring die and roller gap adjustment ring for the new model and adjust the roller gap, the ring mold and need to be the highest roller slight speak to roller to achieve "may transfer non-transfer" state. If adjustments in the function of state, may possibly be appropriate ring mode and growing the stress roller, but definitely adequate is sufficient. Ring die and roller gap is also big, stress roller can not rotate, resulting in blocking pellet machine. Ring die and roller gap is as well tiny, will increase the ring die and roller wear, load up, a critical cause ring die and roller harm. Must promptly check the ring mold and roller gaps, at least verify after each and every four functioning hours. When adjusting the different rollers, pay focus for the path of each roller adjustment must be made relative to the pellet mill roller shaft torque and zero, in order that pellet mill from the asymmetry of energy.

2. Frequency of group maintenance Granulator each and every class need to be done before the inspection, check the transmission components, instruments, Valve Doors, raises oil (Jg with lithium lubricants), and take away iron on iron filings.

3. Correctly installed or replace the ring die and roller is actually a new model together with the new general roll, roll the old model with the old, in order to ring die and roller profiling state close towards the surface shape, ring die and roller of all related nearby space . To ensure that the entire force, and a ring mold material are extremely uniform, can increase production efficiency.
