Description

Technical Field

[0001] The utility model relates to the technical field of rock crushing equipment, in particular to a disc type stone crushing device. Background Art

[0002] In construction projects, gravel is often used as a filler in concrete. For different buildings and roads, the size of the gravel used is different. In the prior art, gravel is usually obtained by crushing rocks and then screening them. However, the existing screening device usually includes a number of screens stacked up and down, and the screen holes gradually become smaller from top to bottom. After crushing, the gravel is rolled and screened from the topmost screen, and the small gravel leaks down layer by layer, and then is separated from the first discharge port.

[0003] However, the above screening device has the following problems during actual use: the stones that leak from the upper layer after screening and fall into the lower layer are not on the leftmost side, but in the middle or right side, and the starting screening position of the stones in the lower layer is closer to the right, resulting in a shorter screening distance for the stones in the lower layer. Therefore, the situation in which large stones and small stones flow out from the same outlet is more serious. The obtained products often need to be screened multiple times to meet the particle size requirements, wasting work time.

[0004] In addition, the existing rock crushers usually crush rocks through two circular crushing rollers, which results in the majority of the crushed stones being of a certain size, rather than obtaining stones of different sizes more evenly, which in turn results in the existing rock crushing device having a mediocre crushing effect and requiring subsequent filtration through a screen, which prolongs the processing technology.

[0048] ⑥ Use the brush in the aggregate box to sweep the target aggregate into the charging box through the discharge port.

[0049] (2) Multiple groups in series

[0050] ① Determine the required aggregate size grouping according to actual project requirements. Figure 3 , the components are grade I aggregate (60≥d>40), grade II aggregate (40≥d>25), grade III aggregate (25≥d>10), and grade IV aggregate (10≥d>5);

[0051] ② Group the particles according to the determined particle size and assemble the instruments separately. One particle size group corresponds to one instrument, and the instruments are connected in series.

[0052] ③ Crush the aggregate according to the above method to obtain aggregate particles of different sizes.

[0053] ④According to the grading formula,

[0054] C u =d 60 / d 10 (1)

[0055]

[0056] C u: Soil inhomogeneity coefficient

[0057] C c : Curvature coefficient

[0058] d 10 : The mass of soil particles smaller than this particle size accounts for 10% of the total mass of soil particles

[0059] d 30 : The mass of soil particles smaller than this particle size accounts for 10% of the total mass of soil particles

[0060] d 60 : The mass of soil particles smaller than this particle size accounts for 10% of the total mass of soil particles

[0061] From an engineering point of view, soil with uneven gradation (Cu≥5) and a continuous gradation curve (Cc=1~3) is called well-graded.

[0062] 50g of grade I aggregate, 150g of grade II aggregate, 600g of grade III aggregate and 200g of grade IV aggregate were selected, and the particle size of the components was taken as the median of the interval.

[0063] Calculated according to the grading formula, Cu=10, Cc=2.5, which meets the requirements of good grading.

[0064] The present invention is not limited to the specific technical solutions described in the above embodiments.
