Variable-frequency planetary ball mill

Abstract

The invention relates to a variable-frequency planetary ball mill comprising a machine shell, a frequency conversion control system, an electromotor, a driving shaft, a driving pulley, a driven pulley, a driving belt, a driven shaft, a mounted bearing, a rotary table seat, a ball milling pot sleeve, a ball milling pot, a presser, an observation bin, a rotary hinge and a door bracing rod, wherein the frequency conversion control system is located at the upper right side of the machine shell; the electromotor is located inside the lower right side of the machine shell; the lower end of the driving shaft is connected with the driving pulley through a key; the driven pulley is connected with the driving pulley through the driving belt; the driven pulley is connected with the lower end of the driven shaft through a key; the upper end of the driven shaft is fixed together with the rotary table seat through the mounted bearing; and the frequency conversion control system comprises a frequency converter, a control switch and an operation panel. The variable-frequency planetary ball mill can realize double functions including soft starting and slow starting and plays a role in protecting the whole equipment; and meanwhile the variable-frequency planetary ball mill has a function of continuous voyage while power failure and is capable of realizing man-computer interaction, strong in intuition as well as convenient and rapid in operation.

Description

technical field [0001] The invention relates to the field of powder grinding equipment, in particular to a variable frequency planetary ball mill. Background technique [0002] The planetary ball mill is designed for crushing, grinding, and dispersing powders such as metals, non-metals, organics, and Chinese herbal medicines. Its working principle is to use abrasives and samples to roll at high speed in the grinding tank to generate strong shear, impact, and Rolling achieves the purpose of crushing, grinding, dispersing and emulsifying materials; the planetary ball mill is equipped with multiple ball milling jars on the same turntable. Grinding balls in the tank collide with each other in high-speed motion to grind and mix samples. This product can grind and mix products with different particle sizes and materials by dry and wet methods. The minimum particle size of the ground product can be as low as 0.1 micron. It can well meet the requirements of various process paramete...

Problems solved by technology

[0003] Existing planetary ball mills use speed-adjustable motors or run at a single speed, manually stop running, and cannot set a program to form an automatic grinding scheme. When the ball mill is hard started, it will cause great damage to the equipment motor and transmission shaft, and the human-computer interaction is poor, not intuitive, and the operation is cumbersome; when it does not need to run at full load, it runs at the maximum output power, wasting electric energy
