For example, the conventional three-roller has the diameter of 150mm, the rotating speed ratio is 1:2:3, and the linear speed ratio of the roller surface of the three rollers is 1:2: 3; in the unequal-diameter three-roller, the diameters of a feeding roller 6, a middle roller 7 and a discharging roller 8 are respectively 100mm, 150mm and 200mm, the rotating speed grade ratio is 1:2:3, and the linear speed ratio between the rollers is 1:3: 6; the larger linear velocity difference is formed, and the shearing force to the material is improved.
Example 2
FIG. 4 is a schematic view of the overall structure of a unequal-diameter three-roll grinder in which three rolls are arranged in a non-linear configuration; figure 5 shows a schematic of an arrangement of three rollers. The difference from embodiment 1 is: the axis connecting line between the feeding roller 6 and the middle roller 7 and the axis connecting line between the middle roller 7 and the discharging roller 8 are arranged in a non-linear shape. This unequal-diameter three-roller grinding machine can adopt prime mover 1 to provide power for pan feeding roller 6, intermediate roller 7, discharge roller 8, and pan feeding roller 6 adopts the gear connection of different transmission level ratios with intermediate roller 7, intermediate roller 7 adopts the gear connection of different transmission level ratios with discharge roller 8, refer to fig. 5, then through setting up the gear of different transmission level ratios, the control of present roller relative motion's linear velocity size makes speed control more convenient.
Example 3
The unequal-diameter three-roller grinding machine is more suitable for grinding materials (such as printing ink and coating materials) sensitive to temperature increase. Referring to fig. 6, the unequal-diameter three-roller grinding machine comprises a frame 2, a feeding roller 6, a middle roller 7, a discharging roller 8 and a prime motor 1, wherein the feeding roller 6, the middle roller 7 and the discharging roller 8 are sequentially mounted on the frame 2 through a bearing mounting seat 5, a discharging roller scraper 4 is arranged on one side of the discharging roller 8, and the cutting edge of the discharging roller scraper 4 can be adjusted to press the discharging roller 8; the diameters of the feeding roller 6, the intermediate roller 7 and the discharging roller 8 are not completely the same or different; the axis connecting line between the feeding roller 6 and the intermediate roller 7 and the axis connecting line between the intermediate roller 7 and the discharging roller 8 are arranged in a V shape; of the feed roller 6, the intermediate roller 7, and the discharge roller 8, the larger the diameter is, the larger the linear velocity of the relative movement of the roller surfaces becomes.
The V-shaped arrangement in the embodiment refers to a V-shaped structure with an upward opening or a V-shaped structure with a downward opening, that is, the feeding roller 6 and the discharging roller 8 are positioned on different left and right sides of the middle roller 7, and the feeding roller 6 and the discharging roller 8 are positioned on the same upper and lower sides of the middle roller 7. Fig. 6 shows the V-shape with the opening facing upwards. In this embodiment, the central connecting line of the three rollers is in a V shape, and the middle roller 7 protrudes downwards, so that compared with the linear arrangement, the protruding length is longer, and the material has a longer running length after being ground for the first time, so that better heat dissipation can be performed before being ground for the second time. In this embodiment, it is still further preferable that the diameter of the intermediate roller 7 is increased, the diameter of the intermediate roller 7 is set to be larger than the diameter of the feeding roller 6 and the diameter of the discharging roller 8, the diameter of the discharging roller 8 is larger than the diameter of the feeding roller 6, the conveying length between the first grinding and the second grinding is further increased, and after the second grinding, the material is discharged by the discharging scraper via the upper convex surface of the discharging roller 8 with a long area. The extrusion and shearing action of grinding, the material can produce great temperature rise, on the long convex surface down of intermediate roll 7 and the long convex surface up of discharge roll 8, the heat of the thin layer material after grinding gives off fast. The material temperature emission is good, and the material temperature does not accumulate too much.
And (3) comparing the heat dissipation effects of the rollers with equal diameter and unequal diameter, wherein the sum of the diameter values of the three rollers is equal, and the relative movement linear speeds of the roller surfaces of the corresponding rollers are the same, and fig. 7 is a heat dissipation effect comparison graph. It can be seen that through the optimal arrangement of this embodiment, the diameter of intermediate roll is the biggest to make the material from the first grinding after, the length that will operate is longer, and heat radiating area is bigger, and the radiating effect is better.
Example 4

Compared with the linear arrangement, the concave length of the middle roller 7 is reduced. After the first grinding, the material passes through the inner convex surface of the intermediate roller 7 with shorter length, and the running length is shorter, so that better heat preservation can be carried out before the second grinding. In this embodiment, it is further preferable that the diameter of the intermediate roller is smaller than the diameter of the feeding roller and the diameter of the discharging roller, and the diameter of the discharging roller is smaller than the diameter of the feeding roller. After the first grinding, the materials pass through the short inner convex surface of the middle roller 7, and after the second grinding, the materials pass through the side convex surface of the discharging roller 8, so that the materials are rapidly collected by the scraper, the heat dissipation of the materials is small, and the heat preservation effect is obvious.
And (3) comparing the heat preservation effect of the rollers with equal diameter and unequal diameter, wherein the figure 8 is a heat dissipation effect comparison graph, the sum of the diameter values of the three rollers is equal, and the relative movement linear speeds of the roller surfaces of the corresponding rollers are the same. It can be seen that through the optimal setting of this embodiment, the diameter of intermediate roll is minimum to make the material from the first grinding after, the length that will operate is shorter, and heat radiating area is littleer, and the heat preservation effect is better.

The side V-shaped arrangement can be modified by one skilled in the art to suit the heat dissipation or the grinding of materials to be insulated, based on the principles and teachings of examples 3 and 4. The diameter can also be correspondingly set, if the diameter size relation of the feeding roller, the middle roller and the discharging roller is that the diameter of the middle roller is larger than that of the feeding roller and that of the discharging roller is larger than that of the feeding roller, or the diameter of the middle roller is smaller than that of the feeding roller and that of the discharging roller is smaller than that of the feeding roller.
