grinding balls & lining bricks
series |
To
catch the home and abroad customers’
rapid increasing demand of grinding
media,we develop three series
of grinding balls and lining
bricks with high alumina Balls
series:92%and95% alumina;Micro-crystal
medium-alumina balls series:65%~75%
alumina and silicon carbide
high alumina balls:60%~70% aluumina(also
called brown medium alumina
balls).The customers can choose
the best series that most suitable
for them according to the produce
demand. The detailed information
please refer to the TABLE-1,TABLE-2
and TABLE-3.Characteristics:
High alumina & Micro-crystal
medium alumina.
◆High
wear-resisting:The alumina balls’
wear-resisting is higher than
the common ceramic balls’.When
it is working,the ball will
not pollute the grinded materials
,so it can keep the purity and
improve the stability of grinded
materials especially the ceramic
glaze.(高铝球)
◆High
density:the high density,high
hardness and the high grinding
characters save the grinding
time,enlarge the smashing room.So
it can improve the grinding
efficiency. |

Ceramic balls |
|
The ceramic balls are broadly
utilized as the covering or supporting
materials of the catalyst in the reactors
and the packing in the columns in
such varied areas,for example,petroleum,chemical
industry,chemical fertilizer,natural
gas and environmental protection etc.Upon
request ,we select the optimum packing
for the particular problem or application
as well as the optimum material and
size.
Ceramic balls property
According to the alumina content
different,we have five kinds of balls,the
detailed specification as the table. |
