본 발명은 공기압을 이용한 분쇄광물 이송방법 및 이송장치에 관한 것으로서, 상세히 설명하면 파이프내에서 고압공기를 불어넣으며, 고압공기의 작용과 파이프내의 프로펠라가 가속되어 분쇄광물을 원하는 장소까지 이송시킬수 있는 공기압을 이용한 분쇄광물 이송방법 및 이송장치에 관한 것이다.The present invention relates to a method and a transfer device for grinding minerals using pneumatic pressure, which will be described in detail, injecting high pressure air in the pipe, the pressure of the high pressure air and the propeller in the pipe is accelerated to transfer the grinding mineral to a desired place It relates to a grinding mineral transfer method and a transfer device using.

일반적으로 공기를 이용한 분쇄광물의 운송방법으로는 분쇄광물을 투입구에 투입한 후, 고압공기로 배출하는 방법과 진공 흡입식의 방법이 이용되고 있으나,In general, as a method of transporting crushed minerals using air, pulverized minerals are introduced into the inlet, and then discharged into high pressure air and vacuum suction method.

고압공기 배출방법은 비중이 높은 광물을 운송할 수는 있으나 투입구에 별도로 투입장비가 투입하고 이를 고압공기로 송풍하여 배출하는 불편이 따르고,The high pressure air discharge method can transport minerals with high specific gravity, but it is inconvenient to separate the equipment into the inlet and blow it out by high pressure air.

진공흡입 방법은 일정한 밀폐장소로의 흡입만이 가능하여 분쇄광물질을 야적장 등에 운송할 수 없는 불편이 있어서 콘베어를 사용하는 것이 보편화된 실정이다. 최근에는 파이프내에서 공기를 이용하는 방법이 많이 개발되고 있다.Since the vacuum suction method only allows suction into a certain sealed place, it is not convenient to transport the crushed minerals to a yard, etc., and therefore, it is common to use a conveyor. Recently, many methods for using air in pipes have been developed.
