Airflow pulverizer is equipped with powder modifiers to reach ideal effects on powder.
According to the physical properties of graphite (natural graphite, artificial graphite, spherical graphite), the high-precision stream pulverization classifier is used to accurately control the grading particle size, and different models can be selected depending on the amount of consumption. According to the material characteristics, natural graphite can select the MQW series gas flow grinding, and the artificial graphite grading can select the FW series airflow classifier, spherical graphite shaping can be selected from the CSM series mechanical ultrafine pulverizer - graded impact grinding.
The ultrafine powder is modified, and the gas flow pulverizer can be used to use the modifier, in the collision of the powder in the gas stream pulverizer, the powder modifier is modified to the powder. To achieve the ideal effect of customers.
1. Use of powder modifier:
In order to cooperate with
using powder modifier, only in powder Under the silo, the metering pump can achieve a uniform speed premix or the effect of spray feed in the airflow pulverization system. The addition is the crush region, the grading area, and the distribution system.
2. Surface modification technique of airflow pulverization
According to different additions of powder modifiers, the integrated process can be divided into the following Two processes:
(1) Dry mixing and crushing modification process
First, the materials and modifiers are uniformly mixed in the mixed apparatus, then directly The airflow crusher is pulverized, the main process parameters are crushing pressure, feed speed, grading speed, powder usage, modified temperature, etc. The process is simple, and the conditions are easy to control, and it is common in the study.
(2) Airflow Crushing Modification Process
The modified process is directly sprayed into the gas flow pulverizer directly into the gas flow And directly in contact with the pulverized particles in the pulverization chamber to achieve the purpose of the surface modification of the powder. A powder modifier adding device is required. The device typically atmosphere into the crushing chamber through the nozzle to complete the modification of the powder particles by the nozzle. This process process is simple to achieve continuous operation compared to dry crushing modified processes.
