Problems solved by technology
In the production operation, whether the operation of the ball mill is stable will directly affect the quality of the product. However, there are many negative problems in the current motor drive: (1) Since the starting load and starting current of the high-power motor are relatively large, it often causes the circuit to start. Power outage, sometimes the running interval is long, and the impact load when suddenly starting will also have a great impact on the life of the ball mill bearing and transmission gear pair; (2) There are a large number of particle dust pollutants floating in the operating environment of the ball mill, As a result, the motor rotor and coil are often adhered and corroded by pollutants, causing frequent failures of the motor; (3) Due to the high quality of the motor itself, it often causes inconvenience to the staff during maintenance or installation, and sometimes even causes injury to the staff production accident

Embodiment Construction
[0011] The present invention will be further described below in conjunction with drawings and embodiments.
[0012] like figure 1 , the system selects the common one-way hydraulic pump model 4 as the power component of the system, and controls the steering of the ball mill by using the three-position four-way electromagnetic reversing valve 9 . At the same time, considering the large mass of the ball mill itself, a low-speed high-torque hydraulic motor is used as the actuator, and if the speed of the hydraulic motor is appropriate, the deceleration device may not be used. In actual operation, the distance between the hydraulic motor and the hydraulic oil station can be increased to remotely control the ball mill.
[0013] Due to the large inertia of the low-speed high-torque hydraulic motor when braking, the control system uses the overflow bridge circuit to control the hydraulic motor. When the three-position four-way electromagnetic reversing valve 9 returns to the neutral...

A ball mill hydraulic control system based on AMESim uses a common one-way hydraulic pump model 4 as the power component of the system, and uses a three-position four-way electromagnetic reversing valve 9 to control the steering of the ball mill. The control of the hydraulic system of the ball mill is stable, the failure rate is low, and the pollution resistance is good, which reduces the danger during maintenance and reduces maintenance costs.
Description
technical field [0001] The invention relates to a ball mill hydraulic control system based on AMESim, which is suitable for the mechanical field. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. Ball mills are widely used in the production industries of cement, silicate products, ferrous and non-ferrous metals, etc. In the production operation, whether the operation of the ball mill is stable will directly affect the quality of the product. However, there are many negative problems in the current motor drive: (1) Since the starting load and starting current of the high-power motor are relatively large, it often causes the circuit to start. Power outage, sometimes the running interval is long, and the impact load when suddenly starting will also have a great impact on the life of the ball mill bearing and transmission gear pair; (2) There are a large number of particle dust pollutants floating in the operating en...
