Roller grinder

Abstract

The invention discloses a roller grinder, which comprises parallel rolling shafts, a grinding controller, a belt, a motor, a base frame, a metal fixing piece and a grinding tank, wherein the parallel shafts are fixed on the base frame by the metal fixing piece; the motor drives the parallel rolling shafts to rotate through the belt; the grinding controller is connected with the motor and is fixedly arranged on the upper part of the motor; a grinding ball is arranged in the grinding tank; the middle parts of the parallel rolling shafts are connected with sections of quartz parallel rolls through metal casings; the quartz grinding tank is arranged on the quartz parallel rolls; the quartz parallel rolls and the quartz grinding tank are arranged in the inside of a microwave emitting cavity; the upper part of the quartz grinding tank is provided with a microwave generator and a microwave controller respectively; the microwave generator is connected to the microwave controller; the synchronous operation of microwave selective heating and grinding improves the heating efficiency during grinding and reduces ore grinding time and ore grinding power consumption; and the equipment is low in temperature and easy and safe to operate.

Description

Technical field: [0001] The invention relates to a roller grinder, which is mainly used in the field of ore grinding, and in particular can satisfy the ore grinding operation under microwave heating conditions. Background technique: [0002] With the development of mineral processing technology, people's requirements for grinding equipment are getting higher and higher. Grinding machines commonly used in laboratories and industries are mainly used to grind materials at room temperature and in an air atmosphere to achieve a certain required particle size. When the material to be ground needs to be heated at the same time during the grinding process, it is necessary to add a heating device. At present, the existing grinding equipment mainly includes: parallel rolling shafts, grinding controllers, belts, motors, chassis, metal fixtures, Grinding jars generally use electricity, hot steam or heat transfer oil to heat the grinding jars and grinding materials through heat conducti...

AI Technical Summary

Problems solved by technology

When the material to be ground needs to be heated at the same time during the grinding process, it is necessary to add a heating device. At present, the existing grinding equipment mainly includes: parallel rolling shafts, grinding controllers, belts, motors, chassis, metal fixtures, Grinding jars generally use electricity, hot steam or heat conduction oil to heat the grinding jars and grinding materials through heat conduction. The heating process has no selectivity for materials, resulting in low heating efficiency and large heat loss during grinding.

In addition, the temperature of the heating device is relatively high, which affects people's operation and safe operation.

In actual scientific research and production, some processing requires selective heating and modification of materials during the grinding process, but existing grinding equipment cannot achieve this.
