Kickstart – a method of soft starting a motor which uses a high
level of current for a short period at the beginning of a current limit
or current ramp start.
Locked rotor current – the amount of current a motor will draw in
locked rotor situations, including full voltage starts. Locked rotor
current is described as a percentage of full load current.
Locked rotor time – the maximum amount of time a motor can
safely run at locked rotor current.
Locked rotor torque – the amount of torque a motor will produce
at locked rotor current (such as a full voltage start). Locked rotor
torque is described as a percentage of full load torque.
Mill, ball – a machine which grinds or mixes materials such as
ores, chemicals, ceramics and paints. The machine consists of a
horizontal cylinder which is rotated, causing the grinding medium,
commonly stainless steel balls, to repeatedly crush the material
inside into a powder.
Mill, hammer – a machine which crushes material into smaller
pieces. Hammers attached to rotating disks repeatedly strike the
material until it is small enough to fall through openings at the
bottom of the mill.
Mill, roller – a machine which crushes material into smaller pieces.
Material is passed between two horizontal rollers which rotate in
opposite directions, crushing the material into smaller pieces.
Milliscreen – a machine which separates solids from slurry, using
an inclined rotating drum with perforated sides.
Mixer – a machine which combines ingredients.
