Ferential transformer to create an electrical signal to be applied to a appropriate measuring implies for example a meter for delivering an indication in the size from the outlet gap. In an illustrative embodiment of this invention, the measuring implies is adapted to control the vertical movement of the primary shaft from the lowest price sand making machine to adjust the outlet gap, as a result enabling minerals to be crushed to a predetermined size.

As standard devices for measuring an outlet gap of a sand making machine, a scale is utilized to actually measure the gap, or in case of remote measurement, there's employed a selsyn transmitter, a selsyn receiver, a potentiometer or the like. These standard forms of measurements described, having said that, tend to lead to troubles as a consequence of complex building in mounting stated selsyn transmitter or the like on a key shaft of a sand making machine, and besides, demands massive capacity for attaching mentioned apparatus which inevitably makes the whole sand making machine bigger than desired.

It's, for that reason, an object of the present invention to supply a gap controlling device for any sand making machine which is easy in mechanism and enables an outlet gap provided inside a cone crusher to be measured and controlled with accuracy.

It is actually an additional object from the present invention to supply a gap controlling device for a sand making machine which is often compactly mounted on a cone crusher requiring no added capacity for attaching exactly the same advantageously from the economical point ofview.

It can be a still additional object from the present invention to provide a gap controlling device for a sand making machine which could be remotely and automatically controlled.
