Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model grinding device overlooking structure diagram.
Fig. 3 is the A-A schematic cross-sectional view of the utility model Fig. 2.
Specific embodiment
As shown in the picture, the utility model it include grinding device, select powder bucket 6 and one group of filter cloth 7, grinding device includes Cabinet 1, the first grinding roller 2 and the second grinding roller 3 are ground, the first grinding roller 2 and the second grinding roller 3 are movably arranged on respectively in grinding cabinet 1, And first forms milling gap between grinding roller 2 and the second grinding roller 3, the diameter of the first grinding roller 2 is greater than the diameter of the second grinding roller 3, grinds Charging cone bucket 4 is equipped at the top of tumbling barrel body 1, the discharge port of charging cone bucket 4 is located at the milling gap of the first grinding roller 2 and the second grinding roller 3 Top, grinding 1 bottom of cabinet are equipped with blanking cone bucket 5,
The top of powder bucket 6 is selected to be equipped with finished product powder outlet, and finished product powder outlet is connected with the suction opening of exhaust fan, choosing Powder bucket 6 is equipped with abrasive import close to the outer wall of finished product powder outlet, and abrasive import passes through delivery pipe and blanking cone bucket 5 Discharge port is connected, and the bottom of powder bucket 6 is selected to export equipped with large particle, selects and is provided with one group of filter cloth peace in 6 bottom outer wall of powder bucket Tankage, one group of filter cloth 7 are separately mounted in corresponding slot,
The discharge outlet of charging cone bucket 4 is provided with skewed slot 9.
The transmission shaft of first grinding roller 2 and the second grinding roller 3 passes through bearing respectively and bearing block is movably arranged on grinding cabinet 1 It is interior, be respectively equipped with the transmission gear 8 being used cooperatively on the first grinding roller 2 and the second grinding roller 3, and by transmission axis drive motor and Pulley transmission mechanism drives the rotation of the transmission shaft of the first grinding roller 2 or the second grinding roller 3, the rotation of the first grinding roller 2 and the second grinding roller 3 It is contrary.
Electroplated diamond abrasive grain layer is coated on first grinding roller 2 and the second grinding roller 3.
Filter cloth 7 is canvas.
The one end for selecting powder bucket 6 is truncated cone-shaped, and selecting the other end of powder bucket 6 is inverted round table shape.
The bearing block at 3 both ends of the second grinding roller is adjustable bearing seat 10, adjusts first by a pair of of adjustable bearing seat 10 Milling gap between grinding roller 2 and the second grinding roller 3.
Working method: the nanometer calcium carbonate semi-finished product after drying are added to the first grinding roller 2 and the second mill by charging cone bucket 4 At the milling gap of roller 3, since the discharge outlet of charging cone bucket 4 is provided with skewed slot 9, the discharge port for feeding cone bucket 4 can be made in this way Close first grinding roller, 2 blanking is more uniform to prevent nanometer calcium carbonate semi-finished product from overflowing, and grinds by the first grinding roller 2 and the second grinding roller 3 Nanometer calcium carbonate after mill is added to along blanking cone bucket 5 to be selected in powder bucket 6, and exhaust fan will select the gas in powder bucket 6 constantly to extract out, Nano calcium carbonate micro powder is extracted out by finished product powder outlet, and heavier particulate matter is fallen into the conveyer belt of conveyer by large particle outlet On, it is added in grinding cabinet 1 and is ground by charging cone bucket 4 again under the drive of conveyer.Filter cloth 7 can work in exhaust fan When air is constantly supplemented in powder bucket 6 to selecting, and prevent large particle from leaking out from selecting in powder bucket 6.When the first grinding roller 2 and the second grinding roller 3 when wearing, and adjusts the milling gap between the second grinding roller 3 and the first grinding roller 2 by adjustable bearing seat 10 to ensure to grind Grind precision.
