6.6 Over-pressure system
The cone crusher and the oil tank unit are equipped with a common over-
pressure system to exclude dust from the equipment. A correctly functioning
over-pressure system is important for the performance of the crusher.
Normally the system consists of a blower and two hoses: one from the
blower and one from the tank unit. The hoses are joined in a T-connector on
the crusher bottomshell. The lengths of the hoses depend on the position of
the blower and tank unit.
As an alternative to the blower installation, a connection can be made to a
compressed air system via a regulator and a filter. If possible, the regulator
and filter should be installed in a heated space.
CAUTION! It is important to install the blower in a dust free environment. Dust will
damage the blower and result in malfunction of the cone crusher.
a) The blower (1) can be mounted horizontally or vertically. If a regulator
assembly (2) is used, it must be installed horizontally.
b) When connecting the blower motor, make sure that the direction of
rotation corresponds to the arrow on the blower housing. If the direction
of rotation is incorrect, the output of the blower will be insufficient.
c) Measure the hose lengths required and cut the appropriate lengths from
the hose coil supplied with the crusher.
d) Connect one hose (3) between the crusher T-connection (4) and the hose
coupling on the blower (1) or regulator (2). Use hose clips.
e) Connect a second hose (5) between the crusher T-connection (4) and the
tank over-pressure coupling (6). Use hose clips.
Minimum and maximum length of hoses 2–15 m
Minimum and maximum pressure 600–1000 Pa
Minimum blower capacity at 600 Pa

NOTE! Hoses, pipes and pipe fittings are not supplied by Sandvik.
NOTE! The air which is introduced into the crusher and the tank must be free from
moisture and dust.
NOTE! Install the blower or regulator at least 0.5 m above the oil tank unit. This will
prevent oil running back to it from the tank.
