Description
A coal
pulverizer is a main auxiliary equipment in coal powder furnace. In
addition to be widely used in coal–fired power plants, it is also
applicable in such an industry as cement, metallurgical and
chemical industries, etc. Its function is to dry, crush and finally
pulverize coal into coal powder for ease of coal combustion in
furnace.
The
pulverizers are generally classified as three categories: low speed
pulverizer, middle speed pulverizer and high speed
pulverizer.
A ball
grinding mill (i.e. ball mill) belong s to low speed pulverizer. A
ball grinding mill is equipped with a number of steel balls in its
rotary tumbler. Revolution: ****5 r.p.m. Pieces of coal are crushed
and grinded into coal powder by the help of steel balls while it
slowly rotates. This kind of pulverizer is suitable for wide range
of coal sort, especially hard smokeless coal. Moreover it is
reliable in operation. But its disadvantages are big volume, heavy
weight, high energy consumption and much noise.
Revolution for middle speed pulverizer generally
ranges from *****0 r.p.m. it has several structure types. It has
such a strong point as compact structure, low energy consumption,
relatively low noise, and easy operation and control. Its weak
points are complex in structure and manufacture, high in
maintenance cost, and unsuitable for hard coal.
A high
speed pulverizer basically consists of a high speed rotator and a
shell. Its revolution generally ranges from **0 to ***0 r.p.m. This
kind of equipment is of following features: simple structure,
compact arrangement, relatively low primary investment.
Unfortunately the wear and tear of equipment is a problem, thus
continues operation time is comparatively short. It only suits
smoke coal which is easy in grinding, rather than hard smokeless
coal.
Obviously there are many wearable and expendable
parts in these pulverizers. We can provide these spare parts at
relatively low prices as per customers’ requirement.
