What is metal powder:
Metal powder refers to a group of metal particles with a size less than 1mm. It includes single metal powder, alloy powder and certain refractory compound powders with metallic properties, which are the main raw materials for powder metallurgy.
Metallic elements are generally silver-white. When metal is under certain conditions, it is black powder. Most metal powders are black.
Application range:
Metal powder can be used as raw material for powder metallurgy products, or it can be used directly.
Double cone dryer is a new type of dryer that integrates mixing and drying. The condenser, vacuum pump and dryer are matched to form a vacuum drying device.
Working principle:
The double cone dryer is a double cone rotating tank. In the vacuum state, steam or hot water is introduced into the jacket for heating, and the heat contacts the wet material through the inner wall of the tank. The water vapor evaporated by the wet material after absorbing heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank is in a vacuum state and the rotation of the tank makes the material constantly turn up and down, inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.
Product features:
The drying speed is fast, generally only a few seconds to more than ten seconds, with the characteristics of instant drying. The temperature of the droplets during the drying process is relatively low, which is particularly suitable for the drying of heat-sensitive materials and can maintain the color, aroma and taste of the materials. In order to prevent the wall sticking phenomenon of the drying tower, this device is equipped with a special structure to effectively prevent the wall sticking phenomenon of the product. The unique finished product air delivery system separates the dried finished product from the hot and humid air in the system in time, avoiding the possibility of moisture absorption or agglomeration of the dried finished product. The boiling point of the material solution under vacuum is reduced, which increases the heat transfer driving force of the evaporator, so the heat transfer area of the evaporator can be saved for a certain heat transfer amount; the heat source for the evaporation operation can be low-pressure steam or boiling hot steam; the evaporator has little heat loss and can be disinfected before drying. No impurities are mixed in the drying process, which meets GMP requirements; the use of a condenser can effectively recover the solvent in the material.
