A dust-collecting box 3 is provided on the side wall of the crushing chamber 1, and a dust-collecting pipe 5 is provided between the dust-collecting box 3 and the dust-collecting plates 8. This design uses the multiple dust-collecting holes 81 on the pair of dust-collecting plates 8 to collect the dust generated by the crushing rollers 10 crushing molten quartz through the dust-collecting pipe 5 into the dust-collecting box 3. This provides good dust removal, prevents dust from being inhaled by personnel, and improves safety. The pair of dust-collecting plates 8 and the pair of guide plates 7 form a chamber. When the crushing rollers 10 crush the molten quartz, dust remains inside the chamber. The dust-collecting holes 81 on the dust-collecting plates 8 facilitate the extraction of dust from the chamber, enhancing the dust removal effect. The guide plates 7 are inclined downwards.

[0016] Reference Figure 2 and Figure 3 The dust collection box 3 is equipped with a filter screen 15 located above the suction pipe 5, and a suction fan 16 is installed on the top of the dust collection box 3. This design filters dust through the filter screen 15 to prevent dust from being discharged from the dust collection box 3 and remaining inside the dust collection box 3; the suction fan 16 facilitates the entry of dust into the dust collection box 3.

[0017] Reference Figure 2The dust collection box 3 has a cleaning ramp 13 on the lower inner wall, and a cleaning port 31 connected to the cleaning ramp 13 on the side wall.
