The mode of operation of described vertical type material falling prevention three-roll grinder is that hydraulic PLC controls.
Described vertical type material falling prevention three-roll grinder adopts computer to control, and can be furnished with compensation data directly at the liquid crystal display display control, and formula is set, water temperature is set supervisor, and dynamic menu is more directly perceived, and is more convenient to operate; Described slow roller 4 is 1:4 with the speed ratio of described central roll 5, described central roll 5 is 4:13.19 with the speed ratio of described fast roller 3, this speed is comparatively more suitable than arranging, both can guarantee the abundant grinding of material, can guarantee the stable operation of roller again, the phenomenon because of the excessive velocities driving do not occur, can not reduce because speed is too slow grinding efficiency yet.
Described fast roller 3 is all consistent with the material falling direction at the velocity attitude at tangent place with described central roll 5, and described slow roller 4 is all consistent with the material falling direction at the velocity attitude at tangent place with described central roll 5; In the tradition three-roll grinder, turning to of described central roll 5 and described fast roller 3 is opposite with the material falling direction, and because material viscosity is inadequate, the material on central roll is difficult to be delivered on fast roller; And the direction of rotation of the described central roll 5 of three-roll grinder of the present invention and described slow roller 4 is all consistent with the material falling direction, is convenient to material and enters between two rollers, realizes grinding fully, and effect is better.Described fast roller 3 is connected by gear with described central roll 5, and described central roll 5 is connected by gear with described slow roller 4.
Described vertical type material falling prevention three-roll grinder also comprises the blade 10 that is arranged at described fast roller 3 one sides, described blade 10 is close on described fast roller 3 surfaces, when described fast roller 3 rotates, the material that sticks on described fast roller 3 will be scraped, and guarantees that all materials through grinding finally all drop in described blanking device 11; The blanking device 11 that is arranged at described fast roller 3 downsides and arranges with respect to described frame 13 sidewall slope, be arranged at described frame 13 bottom motors 2, between described motor 2 and roller, by belt, connected, and described motor 2 connects described fast roller 3 by triangle V band.
A kind of improved grinding method, be applied in described vertical type material falling prevention three-roll grinder, and the method comprises the steps:
During processing materials, material is poured between described slow roller 4 and described central roll 5, described slow roller 4 and described central roll 5 rotate material are ground;
In process of lapping, judged whether that material drops;
In process of lapping, if there is material to drop, the material that drops can drop between described fast roller 3 and described central roll 5, by described fast roller 3 and described central roll 5, is rotated the material that drops is into ground;
If material does not drop, the material that ground between described slow roller 4 and described central roll 5 can be taken between described fast roller 3 and described central roll 5 by described central roll 5, by described fast roller 3 and described central roll 5, is ground;
After grinding end, described blade 10 can drop in described blanking device 11 it by under material scraper, and blanking device is in reciprocating motion always or with slight vibration, the material after guaranteeing to grind falls in magazine smoothly.
Note, above are only preferred embodiment of the present invention.Skilled person in the art will appreciate that and the invention is not restricted to specific embodiment described here, can carry out for a person skilled in the art various obvious variations, readjust and substitute and can not break away from protection scope of the present invention.Therefore, although by above embodiment, the present invention is described in further detail, the present invention is not limited only to above embodiment, in the situation that do not break away from the present invention's design, can also comprise more other equivalent embodiment, and scope of the present invention is determined by appended claim scope.
