With the continuous increase in social needs, Hammer Pulverizer with TAR continues to improve in the use of performance, finished product quality, service life, etc., very well, which is well processed into microtes and even nanoscale fine powder, and it is already chemical. Food, pesticides, cosmetics, dyes, coatings, electrons, etc. have been widely used.
Hammer Pulverizer With Tar has a wide range of pulverized granularity, simple and convenient, but during the pulverization process, there is often a case where the crushing effect is different.
The crushing effect is mainly affected by the following factors:
The temperature and pressure of the gas ratio, the feed particle size, the working fluid, and the pulverization aid. The gas-solid ratio of the pulverizer in crush is an important technical parameter and an important indicator. If the gas is too small, the kinetic energy of the airflow will be insufficient, which will affect the fineness of the product. But if the gas is too high, not only will waste energy, but will even degrade the dispersion performance of certain pigments.
When pulverizing hard materials, there is a stricter requirement for the particle size of the feed. In terms of titanium powder, it is necessary to control 100 to 200 mesh when pulverizing calcination; the material after pulverizing surface is generally 40 to 70 mesh, and cannot exceed 2 to 5 mesh.
So, should you choose how high pressure when crushing? Those skilled, this is mainly dependent on the comminutability and fineness requirements of the material.
Technical parameters:
Finished granularity: D50: 0.8-5μm
Production capacity: 4.5 +/- 10% / T
In production, a certain number of materials must be maintained in the airflow grinding chamber. In the case where the flow rate of the pulverized gas is not changed, the material in the grinding cavity is large, the gradient current is large, and the material is small in the grinding cavity, the gradient current is small.
In addition, feed speedThe degree must remain uniform and stable, don't be too fast or too slow.
If the feeding speed is too fast, the device will overload.
Regular maintenance equipment, often check whether the air supply pressure meets the pressure required, and the gas flow grinding motor, after 3,000 hours of operation, or long-term shutdown and long-term storage, should be cleaned in a gas flow grinder nozzle and grindingThe inner wall of the cavity and attached to the material grading portion to prevent the effect of gas flow grinding on the grinding effect.
