Brief Introduction

Automatic Casting Grinding Balls Production Line adopts the sand coated metal mold type process technology, widely used to produce the chrome ball grinding media (mill ball), crankshaft, brake drum, wheel hub, casting ball, casting section, water meter case, engine cylinder cover and some other medium-small size of castings.

The grinding balls production line drives by hydraulic, pneumatic and electric method, PLC automatic control.

  • vibrating sand falling unit
  • sand blowing unit(double/four working position)
  • pushing mold/sending mold unit
  • delivery roll
  • pouring system 

Automatic grinding balls production line is the assembly line with sand molding device, tilting type pouring system, iron mold opening and closing position, flipping down material position, etc. The entire line is controlled by the PLC program, HMI can show the working situation directly from the touch screen so that to let the operator find out the problem easily from the program. You can find a working video bellow. 

The whole set of the grinding media making machine is divided into 3 parts: molding part, pouring part, and cooling part.
