[0024] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0025] according to Figures 1 to 3 As shown: This embodiment provides a crushing and double stone mill combined flour mill, including a grinding mechanism, the grinding mechanism includes a first powder sifter 401, a second powder sifter 402, a roller grinding mill 300 and two groups of stone grinding mills 500, and a wind conveying system for connecting various devices of the grinding mechanism, wherein:

[0026] The raw material inlet of the roller mill 300 is connected to the silo 100 through the powder lifting mechanism 200, so as to convey grain as raw material to the roller mill 300. The powder outlet of the roller mill 300 is connected to the raw material inlet of the first powder sifter 401 through the powder lifting mechanism 200. The roller mill 300 can improve the grinding efficiency and achieve the primary grinding effect. At the same time, the first powder sifter 401 is used to complete the output of the finished flour in the primary grinding stage.

[0027] The discharge port of the first powder sifter 401 is connected to the raw material inlet of the stone mill 500 through the powder lifting mechanism 200, and is used to transport the flour that does not reach the processing accuracy to the stone mill 500 for re-grinding. The raw material inlets of the two stone mills 500 are connected to the same powder lifting mechanism 200. The stone mill 500 includes two symmetrically distributed ones, so that the powder outlets of the two stone mills 500 are located at the same position. In this way, the re-grinding efficiency of the stone mill 500 can be equivalent to the initial grinding efficiency of a double-roller mill 300, so that the system operation is relatively stable and reliable, and a certain working efficiency is maintained. The powder outlet of the stone mill 500 is connected to the raw material inlet of the second powder sifter 402 through the powder lifting mechanism 200, and the second powder sifter 402 is used to complete the output of the finished flour in the re-grinding stage;

[0028] On this basis, the discharge port of the second powder screener 402 is also connected to the silo 100, and at the same time, a bin separator 101 connected and fixed thereto is provided at the inlet end of the silo 100. The bin separator 101 is connected to the raw material inlet of the roller mill 300 through the powder lifting mechanism 200 to meet the grain transportation. At the same time, the silo 100 can also store the unprocessed remaining materials. The silo 100 includes a plurality of units, which are respectively used to store unprocessed grains, recovered remaining materials, etc. An adjustable baffle connected to different units is provided at the bottom of the bin separator 101, and different materials can be transported to different units through the bin separator 101;

[0029] The powder outlets of the first powder sifter 401 and the second powder sifter 402 are respectively connected to the flour outlet 600 , so that the finished flour products of the primary grinding stage and the secondary grinding stage are outputted through the same flour outlet 600 .

[0030] The wind conveying system includes a fan 700 and a wind conveying pipeline 701 connected to the fan 700. The wind conveying pipeline 701 is respectively connected to the first powder screener 401, the second powder screener 402, the roller mill 300, the stone mill 500 and the powder lifting mechanism 200 to meet the negative pressure conveying effect between the modules.

[0031] The powder lifting mechanism 200 includes a brake dragon 201 and an air shutoff 202 which are connected to each other. The air shutoff 202 is installed at the bottom end of the brake dragon 201 and is respectively connected to the raw material inlets of the first powder sifter 401, the second powder sifter 402, the double-roller mill 300 and the stone mill 500 for conveying materials to meet the lifting and conveying needs of grain, flour and residual materials in each link. An air volume regulating device 203 is installed at one end of the brake dragon 201 which is connected to the wind conveying system. The air volume regulating device 203 is used to adjust the wind force of the powder lifting mechanism 200 to control the conveying and separation effects of each module.

[0032] For the above-mentioned crushing and double stone mill combined flour mill, in order to meet the requirements of a crushing and double stone mill combined flour mill with a stable assembly structure and small space occupation, the following method is adopted for the installation of the stone mill 500, the first powder sifter 401, the second powder sifter 402 and the fan 700 in its specific assembly structure:

[0033] The stone mill 500 is mounted and fixed on the first base 801, and the first base 801 is respectively mounted on the bottom of the corresponding stone mill 500;

[0034] The first powder sifter 401 and the second powder sifter 402 are fixedly mounted on the second base 802, and the second base 802 is located on the left side of the stone mill 500 and is vertically distributed as a whole. The first powder sifter 401 and the second powder sifter 402 are mounted on the left side of the second base 802, and the first powder sifter 401 and the second powder sifter 402 are arranged in parallel in front and back positions;

[0035] The fan 700 is fixedly mounted on the upper part of the third base 803, which is equivalent to the installation height of the wind power transmission pipeline 701. The third base 803 is fixedly mounted on the upper part of the stone mill 500;

[0036] At the same time, the second base 802 is fixedly connected to the first base 801 and the third base 803. In this way, on the basis of space utilization, each device is connected as a whole through the corresponding base connection position, and each device will not move individually, thereby meeting the assembly requirements. At the same time, the installation of the powder lifting mechanism 200 and the wind conveying pipeline 701 can be assembled based on each base, which ensures the assembly accuracy and is conducive to the stable operation of the system.
