Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a raw material grinding equipment with controllable hydraulic pressure. Background Technology

[0002] A ball mill is a device used to further pulverize materials after they have been crushed. This type of ball mill uses a certain number of steel balls as grinding media inside its cylinder. It is widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics.

[0003] The existing Chinese patent with publication number CN118045673B discloses a cement raw material grinding equipment, which relates to the field of grinding technology. It includes a support plate and a grinding assembly. The grinding assembly is mounted on the support plate, which also houses a drive assembly, a feeding assembly, and a conveying assembly. A scraping assembly is mounted on the conveying assembly. Both the drive assembly and the scraping assembly are connected to the feeding assembly. The drive assembly is connected to the grinding assembly. The feeding assembly includes a fan, which is fixedly mounted on the support plate. The conveying assembly includes a support box and a conveying unit. The support box is fixedly mounted on the support plate, and the conveying unit is located on the support box. A second filter screen is installed inside the support box, located below the conveying unit. The support box has a cavity interior and an air outlet connected to the air inlet of the fan. This invention facilitates the replacement of grinding media and solves the problem of air pollution caused by powder being thrown up during unloading.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, cement raw materials require grinding equipment during processing. Traditional ball mill control methods mostly use motor drive, but when operating in environments with high pollution levels, the motor may frequently fail, leading to high subsequent maintenance costs and affecting overall work efficiency. Furthermore, when using motor drive, it is impossible to accurately control the operating parameters of the ball mill and provide stable driving force. All these problems affect the use of the equipment. Utility Model Content

[0019] 1. This utility model replaces the original motor drive with a hydraulic motor drive by modifying the overall device. A proportional valve and amplifier are installed on the upper end of the hydraulic motor, which can convert mechanical energy into hydraulic energy to drive various actuators. The proportional valve receives electrical signals from the amplifier. These signals are amplified by the proportional amplifier and then output current proportionally to the proportional electromagnet of the proportional valve. After receiving the current, the proportional electromagnet generates a corresponding output force and pushes the valve core to move proportionally. In this way, the proportional valve can accurately control the flow rate and change the direction of the liquid flow, thereby achieving precise control of the position or speed of the actuator. This effectively prevents the problems associated with traditional ball mill control methods that often use motor drives. However, in environments with high pollution levels, the motor may frequently fail, leading to high maintenance costs and affecting overall work efficiency. Furthermore, motor drives cannot accurately control the operating parameters of the ball mill and provide stable driving force. Attached Figure Description
