Abstract

The invention discloses a vertical pulverizer for grinding ultrafine powder. The vertical pulverizer for grinding ultrafine powder comprises a mechanical mechanism and a hydraulic mechanism, wherein a proportional valve control amplifier (16) of the hydraulic mechanism comprises an input interface unit (18) connected with an electric controller (17); the input interface unit (18) is connected with a signal processing unit (19); the signal processing unit (19) is connected with a power amplifying unit (20) connected with a proportional speed regulating valve (15); the proportional speed regulating valve (15) is provided with a displacement sensor (21) connected with a signal conditioning circuit (22); the signal conditioning circuit (22) is connected with the signal processing unit (19). The vertical pulverizer for grinding ultrafine powder, which is provided by the invention, can effectively prevent equipment failure caused by motor overloading; meanwhile, the hydraulic mechanism provided by the invention has superior stability and reliability, and the powder fineness and consistency after grinding are very ideal.

Description

technical field [0001] The invention relates to a vertical pulverizer for grinding ultrafine powder, in particular to a vertical pulverizer for grinding ultrafine powder such as ore, grinding powder and grain. Background technique [0002] Vertical pulverizers are generally used for crushing ore, grinding powder or grain, etc. Its working principle is that the hydraulic cylinder drives down the ore, and the motor drives the pulverizing hub to rotate while pressing down, further improving the pulverizing effect. However, the structure of the hydraulic mechanism of the existing vertical pulverizer is unreasonable, resulting in poor steady-state control characteristics and weak anti-interference ability of the hydraulic mechanism, resulting in instability of the system during work, making the pulverizer grinded The fineness and consistency of the powder are not good, which is the key problem restricting the breakthrough of ultrafine powder pulverization technology.
