1.2 The motor bracket is not installed & the motor is directly fixed on the foundation of the floor and located at the left lower part of the exciter, resulting in the tension of the v-belt and the skidding in the operation process. For this reason, the motor bracket is reinstalled to make the central line of the motor pulley and the central line of the exciter pulley be basically on the same horizontal plane, ensuring that the v-belt is always tension and does not slip.
1.3 The dust cover is not equipped with dust removal pipe, which causes the inside of the vibratory separator to be in a positive pressure state and the dust escapes, thus polluting the environment.
2. The commissioning problems of vibratory separator
2. 1 No-load starting motor easy trip. The first stop check each part of the vibratory separator soft connection, no collision phenomenon: then check that the electric control system, find relay capacity is only 32 and A motor rated current is 30.1 A, small relay capacity. To replace A 46 A relay, will the set values for the trip to 32 A, again start
vibratory separator without tripping. The vibratory separator non-loading operation is normal, and the electric information is 13 A load current, load current is 15 A.
2. 2 After load test the vibrator side seal has the phenomenon of oil leakage, remove the balance wheel after downtime, isolation ring and sealing plate, check the oil seal found within the oil seal lip soft, small amount of interference. To replace a new oil seal (gently attention when installing isolation ring spinning, prevent oil seal lip turns up and cause oil leakage), to test, the leak phenomenon is disappears.
3.Inspection the capacity of vibrating screen
Original parameter: treated materials is limestone (water content < 3%, loose density 1.35t/m3). The information of vibiratory separator is that the size of upper screen hole is 20mm*20mm, the size of lower screen hole is 10mm*10mm. The screening capacity is 100~150t/h.
The screening capacity of the type 2YAX1536 vibratory separator is calculated as, Q = MqoBoLρ
Where, Bo refers to the efficiency width of the
vibratory separator. L refers to the efficiency length of the vibratory separator. qo refers to the capacity of the unit part, the capacity of upper screen is 28m3/m2*h), the capacity of lower screen is 19m3/m2*h). P refers to the loose density of the limestone, 1.35t/m3. M refers to the screen efficiency correction factor, it can be calculated according to the following empirical formula.
M=100×(1-ηn)/7.5=100×(1-0.9)=1.33
Where, ηn refers to the screening efficiency, it is 90%
The capacity of the upper screen: Q1= 1.33×28×1.53×3.6×1.35=276.9t/h
The calculation results show that the processing capacity meets the requirements of 100-120t /h. If the type selection of fine crushing machine increases in the future, 5mm screen mesh can be selected for the lower layer, then: The capacity of the lower screen: Q3= 108.8t/h
The calculation results show that if the particle size of the finished product is controlled within 5mm, it can also meet the processing capacity of 100-120t /h.
