1- 40T/H Pulverized Coal Production Line Energy Saving High Degree
Of Automation
Our Pulverized Coal Preparation Production Line is composed of Raw Coal Storage & Transportation System, Grinding
System, Dust Collecting System, Electrical & Instrument Automation
System. By the consideration of safety protection for equipment and
system, explosion venting valve and nitrogen protection port are
adopted at hot air inlet pipeline of Air Swept Coal Mill and coal
air output pipeline. Speed of Powder Separator is regulated by VVF,
the output fineness could be controlled by adjustment of frequency
converter by remote control.
OUR ADVANTAGE
1. Saving Energy
Air swept coal mill is an ideal coal processing equipment that can
both grind and dry, with characteristics of high efficiency, energy
saving, environmental protection, 8% and above of its grinding coal
can pass through the 200 mesh screen, and the water content can be
under 2%, it is an ideal grinding equipment for coal powders that
are used in industrial furnaces and rotary kilns and other
equipment.
2. Uniform particle size
The improved O-Sepa classifier is a kind of high-efficiency
classifier developed on basis of the technology of common O-Sepa
classifier and using the most advanced technology in the world. The
distribution of finished particles is more uniform, while the
particle size ratio is more reasonable.
3. Environmental protection
Effective measures have been taken to guarantee strict environment
protection standards. Different efficient dust collectors are set
at all dust producing points according to different characteristics
of waste gas.
4. High degree of automation
There is no manual operation in the process of mill running, which
realizes the automatic control with long-term, stable, effective,
makes milling process more stable, realizes fine work of
production.
