Dust will be generated during the crushing process of the modified calcium carbonate by the crusher body 2. After the dust suction pump 712 is started, the dust diffused from the feeding funnel 3 is sucked into the dust suction pipe 710 by the dust suction hood 711. The dust entering the dust suction pipe 710 then enters the dust collection pipe of the external dust collection device through the dust ventilation pipe 713. Subsequently, the dust enters the external dust collection device from the dust collection pipe, thereby achieving the dust removal effect and further achieving the environmental protection effect.
