其分为两种材料，一种采用铸铁螺旋凸棱制造，其造价成本低、较好的耐磨性能

It is divided into two materials, one is made of cast iron spiral ribs, which has low cost, good wear resistance, long service life and convenient maintenance. The disadvantage is that the gripping force is small. The use of spiral ribs mainly allows the ears to rotate and move, which is conducive to the adjacent ribs to grasp the ears well. The other is the common rubber with high wear resistance, because the friction coefficient of rubber is larger than that of metal, it has better grasping ability, high peeling rate, good elasticity of rubber and can reduce the damage to corn. The disadvantage of the problem of shattering is that the cost is high. Because the axial movement resistance of the cast iron roller is smaller than the axial movement resistance of the corn ear, its productivity is reduced. In view of the above reasons, a combination of cast iron roller and rubber roller is used for peeling roller.

It is divided into two kinds of materials, one is made of cast iron spiral convex, its cost is low, better wear performance, long service cycle, convenient maintenance, the disadvantage is that the grip force is small. The use of helical convex prism is mainly to allow the fruit spike to rotate and move, which is conducive to the adjacent convex prism to grab the fruit spike very well. The other is a common rubber with high wear resistance, because the friction coefficient of rubber is larger than the friction coefficient of metal, has a better grasping ability, high netting rate, the elasticity of rubber can also reduce the damage to corn and granulation problems, the disadvantage is high cost. Because the axial motion resistance of the cast iron roller is less than the axial motion resistance of the corn spike, its productivity is reduced. For the above reasons, a combination of cast iron rollers and rubber rollers is chosen for peeling rollers.

It can be divided into two kinds of materials, one is made of cast iron spiral rib, which has low cost, good wear resistance, long service cycle, convenient maintenance, and the disadvantage is small gripping force. The spiral ridge can make the ear rotate and move, which is good for the adjacent ridge to grasp the ear. The other is the common rubber with high wear resistance, because the friction coefficient of rubber is larger than that of metal, it has better grasping ability, high peeling rate, good elasticity of rubber, at the same time, it can reduce the damage to corn and the problem of falling grain, but the disadvantage is the high cost. Because the axial movement resistance of cast iron roll is less than that of corn ear, the productivity of cast iron roll is reduced. In view of the above reasons, the peeling roll composed of cast iron roll and rubber roll is selected.<br>
