Rotation connection is the length direction supporting plate identical with ball grinding cylinder of arc in the lower section of ball grinding cylinder setting section, and supporting plate is along ball
The length direction of mill tube tilts gradually downward, and level-one ball milling chamber be less than at a distance from supporting plate two level ball milling chamber and supporting plate away from
From fixed with the affixed sealing plate of ball grinding cylinder side wall at the both ends of supporting plate and both sides, sealing plate, supporting plate, ball grinding cylinder side wall are formed
Expect chamber, the side wall of the level-one ball milling chamber and two level ball milling chamber of expecting intracavitary is sieve, mesh size and the two level ball of level-one ball milling chamber
Mill chamber is identical, and material is opened up on the side wall for expecting the level-one ball milling chamber and two level ball milling chamber outside chamber and on the sealing plate of supporting plate lower end
Door；It further include the driving mechanism of drive shaft rotation.
Preferably：The driving mechanism includes the gear wheel being set in outside shaft, is arranged outside gear wheel and is driven by motor
The pinion gear being meshed with gear wheel.
Preferably：In the lower section of supporting plate, splicing groove is set.
The utility model has the beneficial effects that：The utility model is conducive to the refinement grinding of material, if by first grinding
Material can meet when needing, directly material is discharged, if material need to be refined again, place to two level ball milling intracavitary needed for
Abrasive body, by primary grinding and by sieve material, particle size range smaller, it is easier to be refined, this practicality
Novel can crush the refinement of material is divided into two steps, and the first step is will be random, the larger material primary comminution of Size Distribution,
Its particle diameter distribution is set to become smaller, second step is by crushing material to required size.

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figure 1, Figure 2 and Figure 3, the utility model includes horizontal cylindrical ball grinding cylinder 1, in ball grinding cylinder 1
Demarcation strip 10 is arranged in portion, forms level-one ball milling chamber 11 and two level ball milling chamber 12, is connected at the both ends of ball grinding cylinder 1 and shaft 4 is arranged, and two
Holder 8 is arranged at the both ends of ball grinding cylinder 1 in the axis collinear of the shaft 4 and ball grinding cylinder 1 at end, and shaft 4 is rotatablely connected with holder 8,
The lower section setting section of ball grinding cylinder 1 is the length direction supporting plate 7 identical with ball grinding cylinder 1 of arc, and in the lower section of supporting plate 7, setting connects
Hopper 9, supporting plate 7 tilt gradually downward along the length direction of ball grinding cylinder 1, and level-one ball milling chamber 11 is less than at a distance from supporting plate 7
Two level ball milling chamber 12 is fixed with the affixed sealing plate 3 of 1 side wall of ball grinding cylinder at the both ends of supporting plate 7 and both sides at a distance from supporting plate 7,
Sealing plate 3, supporting plate 7,1 side wall of ball grinding cylinder form material chamber, and the side wall of the level-one ball milling chamber 11 and two level ball milling chamber 12 of expecting intracavitary is
