The wear-resisting roller shell of described milling roller outer setting, roller shell adopts rich chromium cast iron or steel-casting to add resurfacing welding material.
The described upper preparation of the dish abrasion-proof backing block that rolls, liner plate is by many combinations, and liner material quality is that rich chromium cast iron or steel-casting add resurfacing welding material, rolls dish and is connected with the reductor output flange, and motor drives reductor by shaft coupling and rotates together with mill.
Described inner sieving mechanism is comprised of screen frame (unit), sieve, stationary ring, and it is fixed on upper body by adjusting device.
Abrasion-proof backing block is equipped with in described upper shell inside, and liner material quality is 16Mn or casting wear-resistant liner plate.
Abrasion-resistant lining plate is equipped with in described lower house inside, and liner plate is the casting wear-resistant plate.
Described scraper plate is arranged on the below of rolling dish.
Described apparatus for examination and repair is comprised of maintenance hinged-support, maintenance cylinder.
Operation principle of the present utility model is: the raw material that sand processed is used enters from upper shell central feeding mouth, rolling dish rotates together by the driven by motor reductor, material is under the grinding pressure and shearing force effect of milling roller, material is first broken again through the shearing force shaping of milling roller through rolling of milling roller, make material become the discharge gate that fine grained forms from the rotating ring that rolls the dish outside and the stationary ring inner sieving mechanism and be discharged into lower case, and the part bulk materials that escape in the milling roller gap without fragmentation is got back to by the inner sieving mechanism gear and is rolled in dish, continue grinding and enter lower case to qualified sand material, the sand material discharging opening from lower house under the effect of scraper plate that enters lower house draws off.The grinding pressure of milling roller pressurizes by master cylinder in addition, and this pressure can be adjusted arbitrarily, and the grinding speed of raw material to be the gap length that rotating ring by rolling the dish outside and the stationary ring on inner sieving mechanism form adjust.
The beneficial effects of the utility model: size and rotating ring and the stationary ring gap of the rolling pressure by adjusting milling roller, can adjust easily sand-grading, control rational modulus of fineness, adjusted the content of stone powder in the Machine-made Sand, simultaneously under grinding pressure and shearing force effect, the Machine-made Sand faller gill shape of producing is less, and particle shape is good.The utility model is by dry production in addition, controlled content of stone powder suitable in the Machine-made Sand, optimized the grating of Machine-made Sand, saved water resource simultaneously.
