9. Check whether the funnel is blocked or seriously worn
10. Check whether the hand wheel of oil immersed rheostat in electrical part is at zero position
11. Check the contact condition of motor carbon brush
12. It is not flexible to check the distribution box and operating mechanism
13. Check whether the pointer of ammeter is at zero. 1. Operation method of the equipment
(1) before operation, the equipment must be inspected item by item according to the inspection content
(2) start the oil pump first, and start the motor only after the return oil is normal
(3) pay special attention to the sound of motor and crusher when starting, and stop running immediately in case of any abnormality
(4) start feeding after normal operation of the equipment
(5) ore feeding must be stopped when the operation is stopped, and it can only be stopped when there is no ore in the crushing chamber
(6) stop the oil pump feeding
2. Start up operation sequence:
(1) first check whether the oil immersed rheostat is at the zero position and whether the short-circuit switch is open
(2) press the start button
(3) slowly transfer the hand wheel of the oil immersed rheostat to the starting position until the motor reaches the rated speed
(4) close the short circuit breaker
(5) observe whether the indication of ammeter is normal
(6) the motor shall not be started frequently, and generally it shall not be started more than three times continuously
3. Stop operation sequence:
(1) stop feeding before stop, and stop the crusher when all ores in the crusher cavity are discharged
(2) the operator presses the stop button
(3) turn the hand wheel of the oil immersed rheostat back to the zero position and open the short-circuit knife switch
(4) after power failure without notice or shutdown with load, the ore in the crusher cavity must be taken out to facilitate the start-up after power supply
The official definition of ball mill model and specification is a series of indicators reflecting the nature, performance and quality of the proct, which is generally composed of a series of letters and numbers with a certain number. For example, brand name, grade, composition, content, purity, size, etc. In short, specification refers to the size of performance indicators, and model refers to the name (or code) obtained from the collection of specifications and models
ball mill specification: if it is expressed by the diameter and length of the ball mill cylinder, it can be shown as φ two point two × 7m、 φ two point four × 13m、 φ three × 11 m, etc
ball mill model: also, according to the diameter and length of the ball mill cylinder, it is mqgg 1212, mqG 1212, mqy 1212, mqyg 1212, etc., in which the letter part indicates the abbreviation of the ball mill equipment, and the number part indicates the diameter of the ball mill cylinder. Take mqgg 1212 as an example: this model is a wet energy-saving lattice ball mill φ one point two × 1.2m
generally, there are many models and specifications of mine ball mills, which can be divided into large, medium and small types according to the level. Taking ferrous metals as an example, a large concentrator with a daily processing capacity of 3000t, a medium concentrator with a daily processing capacity of 900-3000t, and a small concentrator with a daily processing capacity below 900t
the commonly used mining ball mill equipment mainly includes
wet energy-saving lattice ball mill. This lattice ball mill mostly deals with coarse minerals and adopts large double row self-aligning roller bearing, which effectively reces the friction force and is easy to start. Compared with other ball mills, it can save 20-30% energy
small ball mills are mainly used in small and medium-sized development enterprises. The proction scale of such enterprises is small, and the investment cost of small ball mills is low, so the investment income of users is fast, and it will not cause a waste of resources. The main ball mill equipment and model parameters suitable for medium-sized concentrator are as follows:
the above introces the definition of mining ball mill model and specification, and the distinction of model and specification according to large, medium and small type selection, and shows the model, specification and parameters of ball mill according to each level, which can be used for reference. However, in the actual concentrator, the specific model and specification of ball mill selected by each concentrator should consider the nature of materials and beneficiation conditions. It is recommended to select qualified ball mill manufacturer for test selection< br />
