Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, the grinding device in a kind of production of food-grade calcium carbonate, including discharge tank 1 and it is located under discharge tank 1
The conveyer belt apparatus 2 of side, 2 end of conveyer belt apparatus are equipped with ring grinding roller 3, and the 3 discharge port lower horizontal of ring grinding roller is equipped with
4.1 surface of roller of roller conveying apparatus 4, the roller conveying apparatus 4 successively offers the first sieve pore 4.2 along conveying direction
With the second sieve pore 4.3, aperture of the aperture less than the second sieve pore 4.3 of first sieve pore 4.2,4.2 lower section of the first sieve pore
Equipped with the first receiving hopper 4.4, the second receiving hopper 4.5 is equipped with below second sieve pore 4.3,4.1 inner surface of roller is equipped with
Helical orbit 4.6,4.1 discharge port of the roller lower section are equipped with material conveying trolley 5；It is set between the discharge tank 1 and conveyer belt apparatus 2
There is the first dust hood 6, is equipped with the second dust hood 7, first dust suction between 3 feed inlet of the conveyer belt apparatus 2 and ring grinding roller
Cover 6 and the second dust hood 7 are connect by air draft pipe 8 with 3 feed end of ring grinding roller, and the air draft pipe 8 is equipped with air pump 9.
Preferably, feed hopper 10 is additionally provided between 3 discharge port of ring grinding roller and 4.1 feed inlet of roller.
Preferably, third dust hood 11, the third dust suction are additionally provided between 3 discharge port of ring grinding roller and feed hopper 10
Cover 11 is connect also by air draft pipe 8 with 3 feed end of ring grinding roller.
The present embodiment working principle is as follows:
Calcium carbonate mineral to be ground is unloaded on conveyer belt apparatus 2 by discharge tank 1 first, and then conveyer belt apparatus 2 will
Calcium carbonate mineral is delivered to 3 feed inlet of ring grinding roller, then into carrying out process of lapping in ring grinding roller 3, the calcium carbonate after grinding
Powder enters in feed hopper 10 from 3 discharge port of ring grinding roller, and the roller of roller conveying apparatus 4 is then entered by feed hopper 10
In 4.1, with the rotation of roller 4.1, calcium carbonate powder advances along helical orbit 4.6, while the lesser powder of partial size is from the
