Supply spiral classifier low weir spiral classifier classifier blades

Purpose and application scope of spiral classifier:
The screw classifier is a grading equipment It is a kind of mineral processing machine that carries out mechanical classification by virtue of the principle that the solid particles have different sizes, shapes and specific gravity, so the settling velocity in the liquid is different
The machine can only be operated after the operator is clear about the structure and working principle of the spiral classifier
  After the spiral body rotates, the ore slurry can be fed to gradually increase the ore feeding amount
  When the screw body is in working state, if it needs to stop immediately in case of special faults (such as jamming and overload), immediately lift the screw body out of the pulp surface, never allow the screw body to press in the pulp, and quickly open the ore discharge valve to avoid siltation
  When starting again, the spiral body must be lowered to a certain position before it can be rotated Mobility
  If the machine needs to be stopped during use, it should be stopped first
When the machine needs to be stopped, the feeding should be stopped first
The machine can not be stopped until there is no material in the process classification
Structure and working principle of the machine:
  The machine is composed of conveyor, spiral, trough, lifting mechanism, lower support (bearing bush) and ore discharge valve
  Description of main structure;
  Conveyor; The coupling of 30500750 motor reducer drives the screw shaft

  Model 1000 consists of motor and reducer
The bevel gear drives the helical shaft
1200 and 1500 models are driven by motor reducer and cylindrical spur gear

  Spirochetes; It is composed of hollow shaft, spiral blade and support
Hollow shaft is made of seamless steel pipe (A2 or 2\
  Spiral blade; It is made of A3 steel plate or white cast iron
It is a vulnerable part and must be replaced according to the wear condition

  Tank body; It is welded by A3 steel plate, which shall not be cracked or penetrated after welding

  Lifting mechanism; It is divided into two types (1) hand turbine reducer, and the spiral body is lifted and lowered by steel wire rope

  (2) The motor, reducer and spiral body are lifted and lowered through the bevel gear screw rod

  The lower support or intermediate bearing bush frame and support screw are divided into two structures
