JFSS series of new compound vibrating screen is developed by our company independently. A new type of energy-saving compound vibration equipment, obtained the national patent 2009.The machine is mainly used in blast furnace, sinter raw material plant, coal, ore and so on.
Secondly, the characteristic of structure
JFSS series of new compound vibrating screen is mainly composed of sieve tray feed, the export of the material on the screen, the export of the material under the screen, the screen box, enclosures, dust extraction port, the composition of the damping device and the excitation source.
Compared with previous vibrating screen, the screen has the following advantages:
1, In the sieve sieve box back-to-back arrangement, the adult shape, compact structure, and can effectively reduce the area is small and rational use of space;
2. The article by rod sieve structure, and the design of the self-cleaning device.The high rate of sieve holes, free of clogging, high screening efficiency;
3. The top of the screen box is provided with a sealing cover, so that under the sealed condition for screening operation in the whole work, can effectively prevent the dust flying around the screen;
4. The screen box with the dust extraction port, can be sucked dust arising from the work of vibrating screen, greatly reduce dust caused by the screening of materials, the effect of dust.
5. The design of the inlet gate, can effectively control the diversion of materials, adjust the amount of material flow on sieve material on both sides, to make the material balance.
6. The screen box can be supported on the fixed base can also be supported with a walk on the bottom of the walking wheel and rail tongs.
Three, installation and commissioning
1. The installation of vibrating screen, the channel is fixed on the basis of the chassis, so that the same end (feeding or discharging side) on both sides of the bearing surface of the bearing seat in the same horizontal plane, the error is less than 2mm.
2. The bottom of the frame with the wheel when installed, will be placed in orbit by the walking wheel, and the same end-bearing surface on both sides should be in the same horizontal plane, the error is less than 2mm.
3. The support seat of the composite spring, To make the boss on the bearing block hole into the spring, And then the lifting of screen box, Be sure to both the upper and lower hole of the composite spring on the supporting plate convex platform, will be the screen vertically, within the combined spring, the screen horizontally at the state level.
4. All spring should be in a vertical position, there shall be no skew, if there is skew, the location of the lower leg should be adjusted to spring.
5. Between the vibrator and the motor and the base mounting bolts must be tightened.The rotation direction of two series isolator must be the opposite.
6. After the factory vibrating screen, such as the installation of more than 6 months, the bearing before installation must be within the vibrator to remove for cleaning, new lithium-base grease lubricating grease (No. 2).Vibrator by re-installed, rotating eccentric block by hand, there shall be no resistance is too large or the phenomenon of death, or should be adjusted timely find out the reasons.
7. The situation of all the fastening bolts installed should be checked.
8. The no-load test run for 4-6 hours, the working temperature of the bearing of vibrating machine should be checked after commissioning, the requirement of bearing the highest temperature of more than 75 degrees Celsius.You should also check the vibration of the screen surface and tighten the situation, found that tighten loose a timely manner.
Four, use and maintenance
1. The order of the start-up screen: If dust collector dust removal device should be run, and then start vibrating, to be functioning after the permit to the screen surface feeding, stop the order to the contrary.
2. In the course of operation to check whether the movement of the screen smooth, if not working properly or has abnormal noise, screening should be stopped in time, find out the reasons, troubleshooting.
3. In the course of using, If there is a need to adjust the time of exciting force, To adjust the balance weight block through the addition and subtraction, But it should be noted that the balance weight block vibration exciter on both sides of the screen box are addition and subtraction at the same time, the same thickness and weight, the balance weight block filled by each group must be consistent.
4. The vibration of bearing the use of 2 lithium base grease, under normal circumstances, a grease refueling every 1-2 months.The use of a vibrator 6 months after the examination of the situation of oil, for example, found that become dry, or have a hard time, should be cleaned to replace oil.The bearing should be clean and check each year at a time.
