4.4.3 Insulation of the bottom of the component section
of the oil tank unit
The component section of the oil tank unit is normally open at the bottom to
provide good ventilation and cooling of the oil pumps. In the winter it might
be necessary to insulate the tank to keep the oil at working temperature and
prevent pressure drop.
4.4.4 Additional oil heaters
In order to heat the oil to the correct temperature, it can be necessary to
install extra heaters. Installation is easiest if this equipment is ordered
together with a new crusher, but extra heaters can also be fitted in the tanks
of older crushers.
4.4.5 Diesel heating system
In plants without 24-hour electrical power, a timer-controlled diesel heating
system can be used. The system starts heating the oil up to three hours before
electrical power is available.
The tank unit is prepared for diesel heating.
The diesel heating system uses a 12 V DC supply.
