5. Microphone Installation
The microphone fitted with two holes (diameter 13mm) 120mm spacing,
has to be set with a rigid support.
Firstly, the needed cable length has to be determined and the microphone interface must be
assembled.
The cable has to be protected by a sleeve up to the microphone connector.
It is advisable to set firstly the microphone on a temporary support in order to find the place, where
the maximum signal is obtained.
Picture 1 : Microphone system dimensions
Warning!
The microphone cable must be absolutely protected against electro magnetic
perturbation (avoid same cable path for power cable especially from motor).

The microphone has to be placed under the mill at the ball’s impact point.
The impact point is situated more or less at the “four o’clock” position (120° to 140°).
Longitudinally, the area to monitor is situated at approximately 1 to 1.5m from the diaphragm,
or at 2/3 of the first chamber.
Figure 2 : Mill description
Figure 3 : Microphone placement (Ball’s impact)
The microphone interface must be installed closer to the mill in order to have the best capture
of the signal and in order to minimize the others mill influences when all mills are installed in
the same room.
The microphone support must be a solid construction because any accidental displacement
which could cause irremediable damage.
The microphone head is adjustable to 360°. A vertical or horizontal support can be used.

IN THE CABLE GLANDS
7.1. CABLE PREPARATION
The interfaces are connected by shielded cables. These cables pass through shielded cable
glands.
Prepare the cable like below
7.2. CABLE MOUNTING
Contact disks (D): Nickel plated brass.
The threaded connector connects the shielding braid to the earthed unit.

Cable C
Cable characteristics: (c)
Shielding: braided copper
Maximum distance: 500 m
Wire resistance: < 40 /km
Important:
The cable shielding (c) must be connected
at both ends to the corresponding terminals
for the differential voltage to be lower than
30 V
