Product Description
The rod mill is an important industrial equipment, mainly used for
fine crushing and grinding of materials. Its working principle is
that the motor drives the cylinder to rotate. Inside the cylinder,
steel rods are installed as grinding media. Under the impact and
grinding action of the steel rods, the materials are crushed.
Structural composition
It is mainly composed of a motor, a main reducer, a transmission
part, a cylinder part, a main bearing, a slow-speed transmission
part, a feeding part, a discharging part, a ring seal, a thin oil
lubrication station, large and small gear jet lubrication, a
foundation part, etc.
Working principle
The motor is driven by a reducer and the surrounding large gear for
reduction transmission, or directly drives the cylinder to rotate
by a low-speed synchronous motor.
Under the action of centrifugal force and friction, the grinding
media are lifted to a certain height and then fall to crush the
materials.
Application field Of Ore Grinding Mill
Mining: It is used for crushing and grinding ores, providing basic
raw materials for subsequent mineral processing procedures.
Building materials: In the cement production process, it is used
for grinding raw materials such as limestone and clay.
Chemical industry: Conduct refined processing on chemical raw
materials to ensure product quality and performance.
Feature Of Ore Grinding Mill
- The cylindrical mill adopts the driving type edge-driving,
center-driving, edge-driving with multi-point meshing, etc; driven
by asynchronous motor reducer pinion and gear as well as
synchronous motor air lclutch pinion and gear.
- Generally supported by static-dynamic pressure bearing on both
ends. Fuuly closed self-aligning 120o osculation rocker bearing is
used. Also single or double slipper staic- dynamic bearings can be
used. The bush is made by NC machine.
- The large open gear is designed using AGMA standard, Equipped with
reliably sealed gear housing and grease ahtomatic spraying
lubrication system.
- The shell is key part of a mill. Carry out finite element analysis
on it with computer to ensure the reliable operation;
- The shell is automatically welded, ultrasonic inspected, wholly
annealed and machined by large special machine tools on one
chucking; there special seal on static-dynamic connection parts ,
ch as feed and discharge hoper, trunnion, etc, to prevent oil and
slurry leakage;
- The liner is of wear-resistance material mad by our company, wich
has been specially heat-treated, with high hardness and long
service life. Also other wear-resistance casting or rubber liner
can be used;
- There are slow speed drive for medium and large mill;
- The high and low pressure lubricating station is equipped for
medium and large mill;
- The control and protection system is controlled by PLC.
