Methods to improve the effect of gas flow, there are these
Airflow milling for drugs, the drug particles after micronization mainly include: increase the specific surface area of the powder powder, a more compact PSD (particle distribution size), more uniform size, better powder control characteristics ( Suspension, dispersion and absorption), more predictable powder properties, color consistency, gloss, opacity.
The airflow pulverizer is a mechanical for pulverizing large-sized solid feedstocks to a required size. Depending on the size of the crushed or crushed material, the pulverizer can be divided into a coarse machine, a crusher, a fine mill, a superfine pulverizer. The external force applied to the solid during the pulverization process has four kinds of pressure rolled, cut, impact, and ground. The rolling is mainly used in thickness, smashing, suitable for crushing of hard materials and bulk materials; cutting is mainly used in fine breaking, suitable for toughness materials; shock is mainly used in smashing, fine milling, super fine mill, suitable The crushing of crispy materials; grinding is mainly in fine mill, ultrafine mill, is suitable for small pieces and fine particles.
Sometimes our way of operation and setting will make the crusher's crushing items are poor, whether it is to improve the speed of the extension or set parameters, it can't be Good effect, what should I do with this situation? Improve the feed speed, the principle of airflow pulverizer is mainly to rely on high-speed airflow to produce a strong collision between powder powder and powder and inner walls to achieve a crushing effect. If the feed is too small, it is unable to achieve a strong collision of frequency, so that the strength cannot be lowered. In addition, if the Draught Fan is too large, the internal negative pressure will also make the collision, and the opposite is not good.
If the above two methods cannot be a crusher to achieve a good crushing effect, it may be possible to clean the airflow pulverizer how to try the effect, and it is possible to be dust, which affects the efficiency of the work (Efficiency) and effect. The airflow pulverizer is pulverized by the negative pressure air flow caused by the fan, into the material collection system, filtered through the filter bag, the air is discharged, the material, the dust is collected, and the pulverization is completed. Widely used in chemical, minerals, metallurgy, abrasives, ceramics, refractory materials, pharmaceuticals, pesticides, food, health products, new materials and other industries. Gasflow pulverizer coarse mixed powder drives the turbine grading device provided by the top of the negative pressure air flow, forced by the fine powder, and is passed from the cyclone collectorAnd the bag dust collector capture, coarse powder is gravity, and the centrifugal force generated by the high-speed rotation of the hierarchical device is set to the four-wall and the settlement returns the pulverizing chamber to continue pulverizing. In addition, pay attention to these matters when using the airflow pulverizer, otherwise everything is empty.
1, during the production process, it is necessary to regularly inspect the temperature rise of bearing. When the temperature rise exceeds 50 ° C, it should be closed, and the reason is to be discovered and excluded.
2, when the new machine is running, the drive belt is easy to elongate, and should pay attention to adjust the appropriate looseness of the belt to ensure the work life of the belt (Lifetime). The airflow pulverizer changes the normal air of the gas source to nitrogen, carbon dioxide gas, which can make the unit become an inert gas protection device, which is suitable for pulverizing grade processing of materials such as flammable and explosive, easy oxidation.
3, the lossants should be inspected, and the quality and production of production (Produce) is replaced in time.
4, the blade, the lining should often inspect the wear (a basic type of component failure). If wear, production (Produce) decrease, the particle size is replaced, and the particle size is replaced.
5, host and grading flow bearing (Bearing) are grease lubrication, using 2 special grease, degree 265-295.
6, Bearing's change is 2000 hours, the amount of lubricating oil is filled with 1/2 (episode) or 3/4 (lower test) of the space in the bearing cavity. Otherwise, it will cause too high of the bearing temperature.
7. The spiral feeder has changed the lipide of 4,000 hours, and Cape Calcium (CA) base lubricants.
