Diamond powder automation
Diamond powder monocrystalline diamond coarse particles by crushing, classification derived. Generally,
the moderately coarse material is crushed to a particle size of micron
or submicron three basic mechanisms, namely crushing, high mechanical
shock {(9m/see above) direct collision between moving particles and
grinding mill is a roller the main role in crushing impact of the role of both the amount of low-speed mechanical crushing equipment. On
methodological terms, using a ball mill for crushing process to produce
diamond diamond powder is the most commonly used method, High-speed
impact of the collision volume of the particles produced crushing,
shearing and grinding action and then the particles produce surface
broken. This fragmentation of Abrasive grinding wheel production method is advantageous because it can produce the ideal particle shape. Jet
mill, the biggest advantage is the speed limit from mechanical line,
capable of producing a high flow rate, especially supersonic jet mill
can produce several times the speed of sound velocity, which can have a
tremendous momentum, it is easier to synthetic diamond and sub-micron ultra-fine powder. From crushed principle that this model is used for the production of diamond powder are more promising.Diamond powder particle size classification is very important in the production process a step. It
involves diamond powder production efficiency and quality, currently
the most widely used in a diamond powder particle size classification
method is a natural sedimentation and centrifugation Diamond blade of
powder production process. Natural
sedimentation method is a direct application of Stokes' law separation
method, according to the same proportion of the particles settling in
the water due to different particle sizes are different principles, by
controlling the sinking height of the classification particle size and
deposition time, although the device Simple, easy operation, stable quality, but the production cycle is longer, labor inefficiency. To
this end, many foreign manufacturers have developed automated grading
equipment, the use of computer technology and frequency conversion
control technology, set up automatic mixing, automatic pump feed,
automatic and computer controlled four water circulation systems,
digital design, precise control and energy-saving electricity, can not be compared with artificial high efficiency, high reliability and good handling. Than
the artificial separation efficiency can be increased by 10 to 20
times, with a high degree of automation, fast sorting, sorting accuracy
accurate, no impurity contamination, no one is interfering factors,
product quality, stability, good reproducibility, labor intensity small business low labor costs, a large one-time feeding amount Ten significant advantages. In line with the powder industry in the future development direction.
