Examples
As shown in fig. 1 and 2, the utility model provides a grinding machine for calcium carbonate production, include: the device comprises a first grinding bin 10, a second fine grinding bin 20 and a third blowing bin 30, wherein the upper end of the first grinding bin 10 is connected with a feeding hole, two grinding rollers 11 connected with a driving motor are arranged in the first grinding bin, and the lower end of the first grinding bin is connected with the second fine grinding bin 20; the second fine grinding bin 20 is large at the upper part and small at the lower part, a grinding table 21 which is connected with a driving motor in an inverted round table shape is arranged in the middle, grinding arms 22 are arranged at two ends, and the lower end is connected with a third air blowing bin 30; the third blowing bin 30 is provided with a blowing pipe 31 and a dust suction device 32, the lower end of the third blowing bin is provided with a material receiving box 33, and the dust suction device 32 is connected with the material receiving box 33.
The upper end of the first grinding bin 10 is connected with a feeding hole, and the crushed small calcium carbonate blocks enter two mutually matched grinding rollers 11 connected with a motor to be changed into small crushed materials and then enter a second fine grinding bin 20 at the lower end; the second fine grinding bin 20 is large in upper part and small in lower part, an inverted circular truncated cone-shaped grinding table 21 is arranged in the middle, grinding arms 22 are arranged at two ends of the second fine grinding bin, the grinding table 21 and the grinding arms 22 are matched with each other to grind the crushed aggregates into powder, and the lower ends of the crushed aggregates are connected with a third blowing bin 30; the third blast bin 30 is provided with a blast pipe 31 and a dust suction device 32, the lower end of the blast pipe 31 is provided with a material receiving box 33, and the dust suction device 32 is connected with the material receiving box 33; the blast pipe 31 blows up the ground calcium carbonate powder, and the dust suction device 32 absorbs the calcium carbonate powder and then injects the calcium carbonate powder into the material receiving box 33. The method has the advantages that the degree of the required calcium carbonate powder is controlled to a certain degree according to the size of the blast air, the calcium carbonate powder is selected more finely, and the accuracy is higher.
As shown in fig. 1, the blast pipe 31 is externally connected with a blower, and the blast pipe is obliquely installed, and an air outlet of the blast pipe is obliquely opposite to the upper grinding table 21; the calcium carbonate powder is blown up better by inclining a certain angle.
