FEM Standard Belt Conveyor Rollers
DIN Standard Belt Conveyor Roller Impact Conveyor Roller For Coal Mine
Conveyors are often seen on construction sites,
especially coal mines. The development of the conveyor is changing
step by step. From the conveyor to the belt conveyor, the idler is
an important part of the belt conveyor. The work of the belt
conveyor is completed mainly by the function of the idler. There
are many kinds of rollers and a large number. It accounts for 35%
of the total cost of a belt conveyor and generates more than 70%
resistance, so the quality of the roller is particularly important.
Although rollers are often bought in the market, some are cheap and
some are expensive. Whether it is expensive or cheap, everyone must
buy good quality. You don't have to say that you get what you pay
for, but the premise is that the quality is good. Because the role
of the roller is to support the weight of the conveyor belt and the
material, the quality must first be guaranteed.
The roll operation must be flexible and reliable.
Reducing the friction between the conveyor belt and the idler
roller plays a key role in the life of the conveyor belt, which
accounts for more than 25% of the total cost of the conveyor.
Although the roller is a small part in the belt conveyor and the
structure is not complicated, it is not easy to make a high-quality
roller.
What is the working principle of the roller?
Generally, the machine has its own working principle to complete
the work. The idler roller drives the tube body of the idler
roller, the bearing seat, the outer ring of the bearing, and the
seal ring to rotate through the friction between the conveyor belt
and the idler roller, and realizes the logistics transmission
together with the conveyor belt.

The trough roller has the characteristics of corrosion resistance:
1. both acid, alkali and salt are difficult to corrode.
2. Trough roller has strong hardness: strong abrasion resistance.
3. Good sealing: The trough roller is fully sealed, and both ends
are equipped with plastic labyrinth seals. The oil and grease will
not leak, which can make the rolling shaft long-term; the trough
roller is in a fully sealed state.
4. Ceramic surface of trough roller: an oxide film is formed, the
surface is smooth, does not adhere to the material, and the
friction coefficient in contact with the conveyor belt is small,
which reduces the driving force of the winding.
5. Long service life of trough rollers: trough rollers are 2-5
times longer than steel rollers, and can reduce belt wear, belts do
not run sideways, and extend belt life.
6. Low operating cost: trough rollers can reduce the overall cost
of belt conveyors and reduce maintenance man-hour
