HOSES
The hoses between the lubricating and
adjusting equipment and the crusher should be
properly fastened in every point, where they
can be affected by rubbing. Points affected by
rubbing should be covered with rubber plates
etc. when necessary.
The minimum bending radius of hoses (R) are:
— Adjusting oil hose
R = 560 mm (22")
(LOS 5-4 KP31.5)
— Lubricating oil hose R = 310 mm (12")
(SAE 100 R1T-20)
— Return oil hose
R = 600 mm (24")
(LVU 075)
The return oil hose of circulating lubrication
should descend all the way from the crusher to
the lubricating equipment. The depression
should be at least 50 mm by every meter
(0.6"/ft) of length of the hose. The sag of the
hose should not exceed 50 mm (2"), to allow
the crusher to breathe via lubricating
equipment after having been stopped (figure
4.8.1). High sag acts like a water seal in return
hose compelling the crusher to breathe via the
dust seal area and to suck the silicious dust into
the crusher.
