Cooling raymond mill

The utility model relates to a cooling Raymond mill comprising a main machine, an analyzer, a cyclone collector and a fan, wherein an air return pipeline between the cyclone collector and the fan is internally provided with a circulating air flow cooling device which comprises certain quantity of heat exchange branch pipes, a cooling cavity, an air inlet cavity, an air outlet cavity and a casing; the heat exchange branch pipes are vertically distributed in the cooling cavity, and an upper port and a lower port of each heat exchange branch pipe are respectively communicated with the air inlet cavity and the air outlet cavity; the air inlet cavity is communicated with the cyclone collector via an air pipe, and the air outlet cavity is communicated with the fan via an air pipe; the sum of the cross sections of all the heat exchange branch pipes are larger than or equal to the cross section of the air pipe between the cyclone collector and the fan; and the upper part of the casing is provided with a coolant outlet communicated with the cooling cavity, and the lower part is communicated with a coolant inlet communicated with the cooling cavity. The cooling Raymond mill has obvious cooling effect and greatly improved milling efficiency, and is suitable for grinding of materials with the melting point temperature of lower than 70 DEG C; and the quality of powders made by the mill is obviously improved.
