Main Usage:
The machine is made up of three parts:main machine,auxiliary
machine and electric
control box. It has the properties of wind selection,having no
sieve or net,and an
even granularity of the processed materiaLThe production process
going on
continuously,the machine can undertake the grinding of chemical
products.food
medcine,medicament,cosmetics,plastic,dyestuff,
resin,cotourant,grain,etc.
Working Method:
The material enters the grinding chamber via the funnel and spiral
conveyor where it is sheared and broken by the fast-rotating
blades.The powder passes the guide
ring and enters the classification chamber. As the classification
wheel is in revolution,both the air force and centrifugal force act
on the powder. As the particles whose diameters are greater than
the critical diameter (diameter of the classification particles)
have a great mass,they are thrown back into the grinding chamber to
be ground again,while the particles whose diameters are smaller
than the critical diameter enter the cyclone separator and bag-type
collector via the material exit pipe by means of negative pressure
wind conveyance.The discharge material meets the requirement for
the product.
Specialty:
1.The design is compact and structure reasonable. The machine is
equipped with an internal classification mechanism so that grinding
and classification are carried
out simultaneously,thus reducing energy consumption.
2.Euipped with a draught fan,which dissipates the heat in the
machine continuously,the machine is fit for the grinding of thermal
sensitive materials.
3.Having a great adaptability and narrow granularity
distribution.The granularity of the product is even and fineness
may reach 80-320 mesh.
4.Regulate the speed of the classifier or amount of the air without
stopping the machine and evenly distributed products of the
required granularity will be obtained.
5.The top cover of the main machine is opened with pneumatic
springs and the body is contructed in such a way that it may be
opened to two sides so that no
hindrance will be met in cleaning and servicing the internal parts.
6.The main grinding parts are made of high-grade alloy tool steel
so that the service life or change cycle of the wear parts is
greatly lengthened.
7.High-speed precision bearings imported from abroad are adopted
for the bearing system so that the whole machine runs smoothly with
little vibration and noise.
8.The pipes are of quick-detachment construction,making detachment
and cleaning quick and convenient.
9.Equipped with a cyclone separator and a collector,so there is no
powder flying during production.The dust collecting bag can
effectively collect the fine powder in
the air current so as to meet the requirements for cleanness and
environmental protection in waste gas discharge.
10.The fine powder collected by the dust collecting bag can be
effectively recycled.thus the material loss is reduced.
