Smelting ore rod mill is a typically
grinding equipment in mineral processing industry, commonly
used in metal or non-metal mine industry, at the same time, in
water conservancy engineering department, building materials,
chemical plant in the power sector and other industries. It is used
for all kinds of ores and rocks.
There is grinding material medium—steel
rods inside rod mill barrel and it is named from
this.
The main working principle of rod mill
is the cylinder using horizontal installation method, on the two
large bearings, through the low speed rotation and all kinds of raw
materials.
There
is a certain amount of grinding medium of mine inside the rod mill
cylinder . Friction force and the centrifugal force make these
medium back and forth inside the cylinder reciprocating rotation
,to be promoted, ditching ,and drain. At this time from the feed
port injection needs to be constantly grinding of raw materials.
The material will be moving to bump ,crushing the grinding medium.
Then shredded raw material discharge barrel with continuous feeding
and this momentum to reach the next level operation process
.
Rod
mill was conducted by motor driven rotary . It relies mainly on the
speed reducer and reducer around the big gear deceleration rotation
,or directly use the low speed synchronous motor through the large
gear deceleration turning around.
Large
rod mill are always equipped with a slow rotation device . When
turning , maintenance or loose load , this device can make host
reached 0.*5 RPM speed , and can be through the roof rotary
department for maintenance
