Brown Coal Milling
* key decision making element is power consumption - needs to be as low as possible.
* Size of particle after milling or crushing 2 - 4mm.
* I have no problems with having a battery of say 5 units doing 100 tonnes each or 2 units doing 250 tonnes. I need a minimum of 250 tonnes in case of breakdown & maintenance.
Pls advise size of unit, and power consumption.

You will recieve a lot of recommendations and suggestions
before long but you have many issues not mentioned in your
inquiry; telling us what you need is fine by all means but we
have no grasp of your operating system.
The issues are simply to clarify and narrow your search needs
because there are collectively hundreds of possiblities/combinations
with regard to breakage and resizing as well as recirculation circuits of
required/desired
Everyone in the business wishes to save on energy costs when
crushing materials as this is one of the largest costs in conveying
sub bituminous and bituminous coals.
Help us, to help you, to help us, help you.
The puzzle starts here:
1. How is the coal in question handled and rehandled prior to
breakage?
a. What is the 500 T.P.H., Run Of Mine coal size if graded?
b. What type of controls, bin segregation, passive and active methods
of coal movement and flow do you now have?
c. What type of fire fighting/fire suppression systems are employed in
the event of a spontaneos combustion fire from coal dust?
d. How much plant area do you have to allow the installation, adequate maintenance
and repair for X number of units with these units in a parallel sizing arrangement
floor plan? You have to have the floor space, ceiling height room, and bridge or
jib cranes capacity to either allow the safe ingress of the largest part of the machine to be
removed and the replacement part lowered into place if a complete primary or tertiary sizing
roll is replaced with its bearing sets.
2. What type of physical plant do you have if any, or
are you at the beginning stages of building or upgrading facilities?
3. What maintenance are you capable of or able to manage
and or contract?
4. Are you financially capable of maintaining an adequate parts
and spares inventory for the 5 machines that you have made an
initial inquiry for?
5. If machinery space requirements are not an issue:
Will you consider or have you considered further flow
splitting to lower the tonnage per line to less than
100 tons per hour to reduce loading surges even further
to add life to the equipment in question?
The use of cast or flywheels produces much usable energy in primary
and secondary breakage crushing systems and there is no real
magic bullet when it comes to energy consumption with breakage
of ores other than using the primary breaker at its lowest setting to
create the smallest out feed size of material exiting the primary crusher.
If you do not have a primary tertiary crusher or crushers to presize the ore prior to
the initial secondary breakage your megavars consumption will not be reduced to any
great degree.
Many manufacturers provide an excellent crusher product for many ores and aggregates.
