Brakes In Belt Conveyor
Dear Mr.Dasgupta,
Types of brake used is depend upon application only.DCEM brake is very reliable & used very offen within the permissible limit of torque. In case of long distance conveyor Thrustor brake is used. ACEM is used where instant stopage is required.In crane it is used.Cost of DCEM brake is marginally higher.
Regards.

In many large overland and downhill conveyors hydraulic caliper brake systems are used and preferred over thrustor systems. DC and AC on-off brakes do not meet the technical needs. ■

Add thoughts:
1. The conveyor design can contribute to lagging failure such as introducing drive slippage using poorly conceived takeup designs or not getting the forces correct
2. Most, if not all, hot vulcanized lagging is superior to cold bonded when measured for overall performance
3. Hot vulcanized lagging must be evaluated for its final form - the autoclave taping distorts the surface dimesions which can lead to belt mal-tracking
4. Product properties such as red muds (iron ore fines, bauxite fines, nickel and brown coal (lignite)) and their influence on the coefficient of friction and material buildup.
5. Item 4 points to load sharing problems as well ■

I think this is a first. The above comment was addressing a question on lagging. I do not know how this jumped. ■
Brakes in Belt Conveyors
It has been observed that in many applications of belt conveyors either DC electromagnetic (DCEM) or thrustor brakes are used. In some cases, even AC electromagnetic brakes (ACEM) are used. I would request you to help me for the following:-
1. Technically which type of brake is better for belt conveyors i.e., DCEM or Thrustor or ACEM, for same braking torque?
2. Costwise which one is better over other types (among DCEM, thrustor and ACEM)
3. Can I have a comparative statement for these three types of brakes ■
