Embodiment Construction

[0024] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0025] like figure 1 As shown, a control method of a ball mill comprises the following steps:

[0026] Step 1) Detect the oil level at both ends of the bearing box of the ball mill through the oil level detection device, and the temperature detection device detects the oil temperature of the oil tank. When the oil level reaches a preset value and the oil temperature is lower than the preset temperature, the upper computer controls the ball mill to start; When the oil level or oil temperature exceeds the preset value range, the upper computer interface will remind or directly control the stop of the ball mill, and start the vibrating motor and the anti-rotary material level switch located at the material inlet of the ball mill.

[0027] When the oil level at both ends of the bearing box is above 30%, and the temperature of the oil tank is lower than 80°C, the up...

Abstract

The invention discloses a control method of a ball mill. The control method can prevent problems generated in a production process of the ball mill to affect production, so that the loss of the ball mill is reduced and the production efficiency is improved. The control method comprises the steps: detecting the oil levels at two ends of a bearing box and the oil temperature of an oil tank, and starting the ball mill when the oil level achieves a predetermined value and the oil temperature is lower than a predetermined value; if the oil level exceeds the predetermined value, reminding or stopping the ball mill, and starting a vibrating motor and an impeding material level switch; normally operating the ball mill, acting the impeding material level switch and starting the vibrating motor to charge the material smoothly; when the impeding material level switch acts over the predetermined time, starting an alarm device connected to an upper computer, closing a charging gate and starting a bypass reamer; detecting the air pressure of a feed inlet/out, wherein when the air pressure is in a predetermined value range, the ball mill is operated normally; when the air pressure exceeds the predetermined value range, alarming and reminding or stopping the ball mill to operate, closing the charging gate and starting the bypass reamer.

Description

technical field [0001] The invention belongs to the field of gypsum board production, and in particular relates to a control method of a ball mill. Background technique [0002] In the production process of gypsum board, the ball mill of the pulverizing system is the key equipment of the clinker system, and ensuring its stable operation is related to the possibility of subsequent stable production. The existing control system does not take corresponding fault prevention and protection measures for the equipment. The frequent faults are the material blockage at the inlet and outlet of the ball mill, the lubrication of the ball mill is not timely, and the equipment is damaged. Contents of the invention [0003] The object of the present invention is to provide a control method of a ball mill, which can prevent the above problems caused by the ball mill in the production process from affecting production, reduce the loss of the ball mill, and improve production efficiency. ...
