The Roll Grinder is a metal cutting machine divided into subsystems, including a load-bearing system, a drive system, a grinding system, and a measuring system. Roll grinders offer over 97% availability to keep the rolling mill production lines in operation. In Roll Grinding applications, the roll diameter is greater than the wheel diameter. The amount of stress between the wheel and roll at the point of contact determines the grinding outcome. Roll Grinding removes cracks or cuts. The operational factors affecting Roll Grinding are Wheel speed, Roll speed, Traverse rate, Sequential Infeed rate, and the type and flow of coolant application. A Grain Huller or rice husker is an agriculture machine that automates removing the trash of rice grains. The Grain Huller is grain processing machinery and equipment that removes the husk from the paddy and makes brown rice. The Grain Huller machine can take off the rice husk, reduce the bursting of the rice grains and the damage to the skin, and try to keep the brown rice intact. A multi-function Grain Huller machine is a new generation product-designed on the base of the N-series of rice milling machine.

Roll Grinding
The use of the Grinding machine is to manufacture precision rods, tubes, bearing races, bushings, and many similar parts. Roll Grinding Machines are high precision machines installed in steel, aluminum, and paper mills and precision machine shops to grind smooth and textured rolls to tight tolerances. The success of Roll Grinding depends on many factors, such as the knowledge and experience of an operator, the condition of the roll grinding equipment, and preventive maintenance of equipment, which all contribute to the surface finish requirements. The following steps should be taken before grinding any roll, including Crown measurement, Roll hardness, and Roll diameter.

Grain Huller
Grains with hulls are bulkier and less dense. The Grain Huller is mainly composed of a hopper feeding device, machine head device, chaff separation chamber, gearbox, rack, and so on. Grain Huller can take off the rice shell, reduce the damage to the rice grains and the skin, and try to keep the brown rice as complete as possible. Grain Huller also reduces traditional models’ volume and energy consumption and provides convenience and practicability for households and small and medium-sized commercial Grain Huller. Grain Huller hulls not only rice but also hull many other grains such as soybean, wheat, maize, pea, cowpea, sorghum, etc.
