OPERATION OF THE MILL GRINDING MILL

The Mill is fitted with two controls for adjusting the output and the fineness of the ground material i.e. THE REGULATING WHEEL and THE FEED CONTROL SCREW. 

 

THE REGULATING WHEEL is for adjusting the distance between the plates to achieve the required fineness. On starting the mill the regulating Wheel should be turned clockwise until the plates just touch. The setting for the material being ground is then made by turning the wheel a few notches either way, the wheel being locked in this position by the click. 

 

THE FEED CONTROL SCREW is for regulating the rate of flow of material by adjusting the angle of the feed hopper. The ground material will vary with the feed rate as well as with the adjustment of the plates. If a fine ground material is required a low feed rate should be. 

The nut on the Feed Control Screw should be locked with the wing nut after setting. If it is required to stop the flow of material, the Feed Control Screw can be lifted up and the cross pin engaged in the slot provided to hold it in the off position. 

 

GRINDING DRY MATERIAL Start the mill and adjust the regulating wheel until the plates just touch. Feed the material into the plates. After the required setting, close the plates two or three notches. Adjust the Feed Control until the required fineness is obtained. If the sample is not fine enough, close the plates further two or three notches; if the Click Holder which carries the Regulating wheel open away from the front, tighten the springs so that the click holder closes. 

 

IMPORTANT Before closing the plates the material to be ground must be fed into the plates and the plates must be opened before shutting off the feed to prevent the plates being damaged by running together. 

 

KIBBLING Start the mill and adjust the Regulating Wheel until the plates just touch. Open the plates a few notches. Adjust the feed to give required fineness. A high output of kibbled material will be obtained. 

 

GRINDING WET MAIZE Start the mill and adjust the Regulating Wheel until the plates just touch Open the plates one or two notches. Adjust the feed to give required fineness.
