Crusher, jaw – a crusher with one fi xed side and one moving “jaw”. The
crusher is wider at the top than the bottom, and material is fed in at the
top and moves down as it is broken into progressively smaller pieces.
Crusher, roller – a crusher with two horizontal rollers which rotate in
opposite directions, crushing the material into smaller pieces.
Current limit – (1) a method of soft starting a motor by limiting the
maximum amount of current the motor can draw during the start. (2)
The maximum amount of current the soft starter will allow a motor to
draw during a current limit start.
Current ramp – a method of soft starting a motor by gradually increas-
ing the amount of current from a specifi ed point to the current limit.
NOTE: The Start Ramp setting will not necessarily match the actual
motor start-up time.
Debarker – a machine that strips bark from logs.
Decanter – a type of centrifuge.
Edger – a machine that cuts large pieces of timber into usable sizes.
Escalator – a type of conveyor which is used to move people up or
down, much like a moving staircase.
Fan, axial – a fan with blades that turn around a shaft, forcing air along
the shaft and across the axis of the fan.
Fan, centrifugal – a fan which pulls air in near the shaft and forces it
out through an opening in the outer edge of the fan casing.
A centrifugal fan produces more pressure for a given air volume than
an axial fan.
Fan, radial – see Fan, centrifugal.
Full load current – the amount of current a motor will draw when
operating fully loaded at full speed with nominal voltage/frequency.
Full load torque – the amount of torque a motor will produce when
operating at full load current.
