Each side shell is connected with the same end of the outer shell and the inner shell.
In this embodiment, the inner housing is inclined with respect to the main housing 140, so that a certain interval is provided between the inner housing and the main housing 140, so that the collecting device is conveniently placed under the sand discharging housing 150 to collect the material, and the material is prevented from flowing to the outside along the outer wall of the main housing 140, thereby causing waste.
In some embodiments of the present invention, as shown in fig. 1 and 2, the euro-pendulum type pulverizer 10 having a sand making function further includes a support frame 160, and the support frame 160 connects the outlet end of the sand discharge channel 130 with the second casing section 142.
When more material is discharged through the sand discharge passage 130, a large downward pressure is applied to the sand discharge housing 150 for a long time, and the sand discharge housing 150 is connected with the main housing 140 only through its upper end, so that the connection may be unstable, the sand discharge housing 150 may be loose, or even the sand discharge housing 150 may fall off. Therefore, the supporting frame 160 provided in this embodiment can perform the function of lifting the sand discharging housing 150 upwards, and can form a good supporting function for the sand discharging housing 150, so as to prevent the sand discharging housing 150 from loosening and even falling.

The scraper knife assembly 125 is used to feed material entering the bottom of the main housing 140 between the grinding roller and the grinding ring 124 as the main shaft 121 rotates.
In some embodiments of the present invention, as shown in fig. 1 and 3, the analyzer 200 further includes an analyzer housing and a rotor 210 mounted within the analyzer housing. In operation, the powder-containing gas enters from below between the analyzer housing and the rotor 210. Due to the rotation of the rotor 210, an eddy flow field is formed around the rotor 210. The particles near the rotor 210 are subjected to the action of inertial centrifugal force and air viscosity, and when the air viscosity is greater than the centrifugal force, the particles enter the rotor 210 and are selected as acceptable products. When the air viscosity is smaller than the centrifugal force, the powder particles are thrown to the inner wall of the shell of the analyzer to become unqualified products, and fall under the action of gravity.
