Installation debugging and use The circular vibrating screen should be fixed on the specialized foundation by the embedded bolt. If there is no special foundation, the shockproof rubber sheet should be installed between the workbench and the engine base. The device should be guaranteed safe and reliable grounding line before use.
Note: after circular vibrating screen is installed, the transportation support should be taken down for fixing the vibrating parts and engine base.
Then set the supporting spring on the upper and lower spring seat circle located in the vibrating parts and engine base. The spring should be completely vertically embedded in the spring seat to keep the screen body balanced and the vibration of the sieve body parts does not have any rigid connection or contact closed to other objects.
Close the power switch to confirm the vibration motor synchronous rotating in the opposite direction with 10-20 minutes idling. At running time, if the device has any abnormal sound, it should be shut down quickly for inspection. After the equipment normally operate, a small amount of screening of materials can be put into the vibrating screen machine through the inlet to confirm the material discharging mouth direction, and then gradually increase the amount of the materials to the required.
When screening the materials, the materials should be put at the top of the vibrating screen machine inlet to ensure that the materials are uniformly distributed on the surface of the screen. It shouldn’t have big impact so as not to damage the screen mesh. Under special circumstances, such as the material strength difference is big, or the materials ratio is large) the used screen should be adopted as a buffer. Users can increase or decrease vibration force of the circular vibrating screen machine according to the layer number of sieve machine, material proportion (by adjusting the angle of vibration motor eccentric hammer on both ends to increase or decrease the vibration force) to make screen in the best sieving effect.
The stopped machine can generate the momentary resonance region. At this point, the amplitude and noise will increase obviously, which belongs to the normal phenomenon. The electric braking system can be deployed to improve it. The sieve surface must not have saved materials opening or closing the machine. Circular vibrating screen mesh need to be checked the tensioning, the damaged, if there are, you should instantly replace them.
Care and maintenance Operations personnel should be strictly in accordance with the requirements of the product use manual to correctly use circular vibrating screen equipment and do well in the plot of equipment, operation, tighten and corrosion and other daily work keep the equipment in the good performance and in the safe and reliable state. The device should be lubricated often with 3 lithium base grease lubricant two times a week. The worker should check whether there is any abnormal sound and abnormal heating phenomenon on vibration motor. The motor bearing temperature limit is 40 ℃higher than the environment temperature. If it is abnormal, the workers should add 3 lithium base grease lubricating oil or replace bearings. The vibration motor should be checked in the oil seal, bearing running after 1500 hours. If any injury occurs, it should be replaced immediately. In addition, every three months you should conduct a minor repairs and maintenance, 6 and 12 months for an overhaul. The disassembling and maintenance of motor should be operated by technical personnel with professional knowledge.
The circular vibrating screen should be often checked whether there is any loose on the fasteners at running time. Regularly check the cable or wear between the vibration motor and the power switch (change a vibration motor wire after two or three months).When it is necessary to replace cables, you should check whether the earth wire is good and it is strictly prohibited the motor running without anything.
