The ball mill is an important component of the mineral process, understands and masters (familiar and can be used) it is not to see. The ball mill is a crushing key equipment after the material is broken. First, it is made of aware of its structure, the main motor, ball mill body, high and low pressure lubricating station, etc.
1, three points of the ball mill main motor:
(1) Start; the main motor power of the ball mill is large, the voltage level is high. The local operation of the mill is low pressure control. The high voltage distribution chamber is generally a certain distance from the grinding machine. The launch of the mill needs to output a signal through the PLC program, which is convenient for the high voltage distribution chamber to connect the shutter switch, and the intermediate relay is installed, and the passive signal node is provided. The main motor is started, and the high voltage distribution chamber needs to operate a host motor run signal on site, and this signal is connected to another intermediate relay and then the input point of the PLC. Because the high voltage distribution chamber and the grinding machine shuttle are far like signal unstable (explained: stable stability; no change), the installation of intermediate relays can provide a stable voltage signal in effect.
(2) Stop, the tripping switch of the main motor of the high voltage distribution chamber is also passed through the intermediate relay.
Note: The stop signal is to connect to the hopping switch of the main motor of the high voltage distribution chamber with the Close point of the intermediate relay. The function of the stop button can be implemented in the PLC. The ball mill is suitable for polishing various ore and other materials, which are widely used in different industries such as mineralization, building materials and chemicals, can be divided into dry and wet-forming milling methods. The normal working state makes this relay constant. Thus, when the accidental power outages between the grinding, the high-voltage distribution chamber still has power, the relay restores the normally closed state connection trip coil to achieve parking (PARK). As shown in Figure 1.
(3) emergency stop; the emergency stop button urgently used in the abnormal state of the equipment. The ball mill is a crushing key equipment after the material is broken. It can be cut (cut; cut off) a low-voltage supply contactor, and the PLC is powered off and then turned on the high-pressure cabinet trip (zhá) switch and stop the main motor. At the same time, the low voltage power supply start button, the stop button, the emergency stop button is powered by 24VDC, ensuring the safety of staff.
2, the starting compressed air station provides the clutch mechanism (Organization) to meet the requirements of compressed air;
3, manually pending the slow transmission clutch mechanism, starting a slow transmission motor, the mill cylinder Start slowly at the drive of the large gear and pinion; the grinder is simplified slowly for 3 to 5 minutes;
4, the main drag motor;
5, pneumatic clutch (CLUTCH) work, mill The cylinder rotates, the mill system enters the working state.
Notes: 1. The continuous operation time of air operation is not less than 12 ~ 24 hours, and the problem is found.Should be solved in time;
2, the air transfer test can be performed normally. The ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metallogenicity and glass ceramics, etc., dry or wet grinding of various ore and other wear materials. . The load trial operation should be carried out in phases. Feeding should be carried out by the discharge in the load operation to avoid unnecessary abrasive and damage to the steel ball and the cylinder liner.
3, the number of balls loaded commissioning 24 2/3 to 48 hours, check and retighten all bolts (composition: composition and the screw head). The ball mill is suitable for polishing various ore and other materials, which are widely used in different industries such as mineralization, building materials and chemicals, can be divided into dry and wet-forming milling methods.
engaged in energy-saving ball mill, ceramic (material: non-metallic minerals) ball mill, cone (Tapered) ball mill, mill equipment more than 30 years, with a ball mill advanced patent certificate more than 10, leading (lead) to the domestic industry Ball mill manufacturer, quality quality, perfect after-sales, escort your equipment and production!
