Re: Conveyor Belt Ice Buildup
Not sure what you are using now but have you tried Liquid Heat. Check out the link below. Works well in Canada.

Re: Conveyor Belt Ice Buildup
Dear Mr.Trentaiken,
I do not know about the installation of conveyor-is it outside the building or inside the building?You can use additional drive to run the conveyor at empty during non-working time which may reduce the problem of ice building.

Heating Of Pulley
Dear sir
you can consider heating of pulley by providing heaters below shall connected thru slip rings . withthe help of rtd you can control the temperature of pully shell at about 20 degree centigrate.
function will be similar to electromagnetic pulley in this cse instead of magnetic coil heating coil will be provided.

Do you have one of these in operation or have information on one? ■

Dear sir
No we have not used same as there is no icing problem in india

Conveyor Belt Ice Build-Up
Dear Mr. Trentaiken,
ISPAT KARMET at KAGAKHSTHAN, they do not stop the conveyor to avoid build up of ice.They use only one drive. But I suggest you that you must use one small drive to run the conveyor during ideal time.
Regards.

Re: Conveyor Belt Ice Buildup
wow
Do not stop the conveyor waste power continously
provide another drive for ideal running again waste power and cluch in both drive
why all these just to remove ice
when other economical methods are available like liqid heat, salt rock or pulley heating are available pl donot sugest in case somebody is using same.
I also request you pl donot mind as this forum is to express your views here you are not consultant and vendor will listen to you

Pulley Heating
We currently use Liquid Heat but still experience ice build up from time to time.
It is a mater of more than just running the belt, we can keep the belt running and still experience Ice Build up. We experience temperatures down to -40 degrees (F).
There are two ideas I am pursuing.
1. An infrared type heater that only heats up the pulley only an will shut of at an amient of "x" degrees.
2. Or, develop a pulley that has built in stator, and rotor and heating coils that will generate its own electricity internally to heat the coils merely by it rotating and that will open the induction circuit once a temperature of "x" is reached. ■
Re: Conveyor Belt Ice Buildup
Dear Trentaiken,
Have you looked at the operation in the Alberta Oil Sands?
They use a special casted polymer for their lagging.
THe Rheinbraun coal field operations use an extruded polymer that looks similar to the Oll Sands. This polymer is applied to a rotating pulley when to lagging is applied from a fixed end tube fitting.
I can put you in contact with Syncrude's operating engineers to allow your further investigation if you have not already done so. ■
Syncrude
Not I have not been in contact with them. If you could send me that information I would appreciate it very much

Conveyor Belt Ice Build Up
Dear Mr.Khalid,
In ISPAT KARMET we have done some work resently.They run the conveyor continously to avoid ice build up.Mr. Trentaiken also written that they do the same.I want to refer my first reply where I have mention about the installation of conveyor-is it outside or inside.
In ISPAT KARMET the conveyors are inside the building & even then there is ice build up.
Mr. Khalid you are very alert about power consumption. In summer people installed A.C in the room.Can you say, it is wastage of power?If it is prime need , you have to use.In the yard conveyor, if you run the conveyor continously, there will be ice build up.
When I was in COLORADO, I saw the use of rock salt in the road as deicer.In belt conveyor system I do not have any experience.I heard about LIQID HEAT.But no experiance.
Regards.

Belt Location
Our Belt Line is located outside. The Liquide Heat product is more effective than rock salt. (More environmentally friendly also).
The largest issue is that the ice will build up on the pulleys. (Both Drive and Bend) IF it builds up unevenly it will track the belt off.
The solutions I see are:
1. A pulley material that Ice will not build up on. (This may work for a bend pulley where friction is not required. However I am not aware of a material that offers friction between belt and pullye but does not let ice "take hold"
2. Heating the pulley either internally or externally. ■
Conveyor Belt Ice Buildup
I am looking for some information on any type of pulley heating system. We have ceramic inlaid pulleys in place and our consumption of deicer is expensive and I am searching for any information on ways to heat the pulley in order to prevent ice buildup. ■
