Carding Machine
A machine which brushes raw or washed fibres to prepare them as textiles.
Centrifuge
A machine which removes solids from liquids or separates liquids from liquid mixtures with simultaneous removal of the solids.
Chipper
A machine used for reducing wood (generally tree limbs or trunks) to wood chips.
Circular Saw
A power saw having a disk-shaped blade, usually with a toothed edge.
Compressor, centrifugal / Compressor, positive displacement / Compressor, piston
Centrifugal compressors use a vaned rotating disk or impeller in a shaped housing forces the gas to the rim of impeller increasing the velocity of the gas. A diffuser (divergent duct) section converts the velocity energy to pressure energy. These are used for continuous, heavy industrial uses.
Compressor, positive displacement
See Compressor, reciprocating.
Compressor, piston
See Compressor, reciprocating.
Compressor, Reciprocating
Uses pistons driven by a crankshaft. Small reciprocating compressors from 5 to 30 HP are commonly seen in automotive applications and are typically for intermittent duty. Larger reciprocating compressors up to 1000 HP are still commonly found in large industrial applications, but their numbers are declining as they are replaced by less costly rotary screw compressors.
Compressor, screw
A machine which forces gas into a smaller space, using two meshed rotating positive-displacement helical screws.
Conveyor, horizontal
A system which carries materials or packages from one place to another, using a continuous moving belt.
Conveyor, vertical
A system which raises and/or lowers materials on a vertical plane, typically in buckets or scoops.
Crusher, cone
A machine which crushes material into smaller pieces. A cone crusher consists of inner and outer vertical crushing cones. The outer cone has its wide end upward, and the inner cone has its apex upward. Material travels down between the two cones and is crushed into progressively smaller pieces until it is small enough to fall out through the gap between the two cones at the bottom.
Crusher, jaw
A jaw crusher consists of a pair of vertical jaws. One jaw is fixed and the other moves back and forth relative to it. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed smaller and smaller as it travels downward until it is small enough to escape from the bottom opening.
Crusher, roller
A type of intermediate crusher consisting of a pair of horizontal cylindrical rollers through which material is passed. The two rollers rotate in opposite directions, crushing material between them.
CSX
CSX soft start controller s providing timed voltage ramp soft start and soft stop, and are perfect for fitting into existing motor control centres.
CSXi
CSXi compact soft starters providing the latest constant current start technology and robust TVR soft stop, to reduce electrical and mechanical stress on motors.d
Current Limit/Constant Current
  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 increasing the amount of current from a specified point to the current limit.
