ZSL series of large-scale cold sinter is a two-axle linear vibrating screen Two bunches of universal coupling by two electric motors to drive the vibrator is doing the reverse self-synchronization operation Makes the screen box produce linear vibration of large amplitude Motor vibration, the vibration screen with large capacity, reliable operation, easy to adjust amplitude, the dynamic load of the base of the workshop and so on.It has been widely used in metallurgy, mining, coal, ports and other industrial sectors.
The series vibrating screen is comprised of screen box, vibrator, spring, isolation, and two-stage vibration isolation spring, the motor and the frame and so on.
Screen frame parts composed of screen frame, screen surface and fastening device.The manufacture of high-quality steel side plate with a piece of screen frame, Side plate, reinforced plate and beam, the vibration the chassis connection between the use of high-strength bolt rivet connection with self-locking nut or ring groove, strong and reliable.
The vibrator is usually installed on the lateral plate, on both sides of the upper part of the screen frame On the vibration of structure is made, a vibrator can also be arranged in the frame of the cardan shaft coupling vibrator using labyrinth seal, lubrication.ZSLF series of vibrator for flange type (also known as mosaic).
Motor installed on the fixed bracket, connected with universal coupling vibrator, motor vibration.
ZSL series of large-scale cold ore sieve are equipped with vibration isolation and two-stage vibration isolation spring.
ZSL series of screening for single-layer screen surface, at the same time the company also produces a variety of models of double-deck large cold sinter screen.
Installation and commissioning
Before installation, check the parts in good condition, complete, and the installed base to conduct a comprehensive clean-up and to check on the screen.
To install the basis of pre-embedded steel plate and anchor bolts by a user-owned, A vibration isolation spring support under the four block embedded within the plane should be in the same horizontal plane on the supporting plate, Flatness error is less than 5mm in the direction of the length, the width of the flatness error is less than 2mm, steel should be the supporting beams.
Motor bracket should be based on when in the height adjustment of the motor and the vibrator, and then carried out the secondary pouring.
Each part of the vibrator is installed, To adjust the relative position of all time, after the secondary vibration isolation spring showed the vertical state, the spring support and lower support plate spot welding in prison.When welding, welding on both sides of the spring support only, not allowed to weld the two ends of the spring support.
With the screen box, vibrator has been installed in the factory and shipped together.The installation should be on the original Assembly to carry out inspection on site, And re torque the bolts, If the installation has exceeded the time of delivery of equipment 6 months, Vibrator should be open, The various parts cleaning and re-Assembly, In the injection of bearing box 2 of the synthesis of lithium base grease, when the re-install the vibrator, to ensure that the symmetry center line of the eccentric block with the axis in the same plane.After the completion of the vibrator assembly, rotating eccentric block by hand, if the resistance is too large or there is sticking phenomenon, we must find out the cause to be adjusted.
The axis of the motor and the vibrator axis should be in the same vertical plane, Taking into account the vibrating screen spring compression deformation after strip material increase, the installation should be below the vibrator motor axis axis 3-5mm.
Machine parts must be reliable, all the bolts may loose.Part of machine vibration the vibration direction in the space between and around the fixtures should be greater than 90mm in the lateral direction should be greater than 50mm.
The vibrating load test run time of 6-8 hours, commissioning, the requirements of smooth vibration, no horizontal swing and abnormal noise.If the above-mentioned problems, should be timely checking reasons, troubleshooting.
The rotation direction of two electric motors should be the opposite, such as rotating in the same direction, the power supply wiring should be changed if an electric motor, so that the two electric motors rotating in the opposite direction.
After the commissioning of vibrating screen for 6-8 hours, you should check the fastening of the sieve plate and a vibrator, such as the discovery of tightening loose a timely manner, the work of the vibration of bearing temperature should be 75 degrees Celsius.
Use and maintenance
Vibrating should avoid starting with material should be starting and running smoothly again after feeding.The stop line should stop feeding, all on screen surface finish and then stop.
In the process of vibrating screen work, should be used to observe the motion of sieve is stable, if not operating properly or have a crash should immediately stop checking.
Should always check fastening bolts around on the screen, and if it is found loose, timely tighten it.
The vibration of bearing the use of 2 synthetic Lithium-based grease lubrication.A lubricant filling each month under normal circumstances, no more than the amount of oil bearing cavity volume from 1/3 to 2/3.After six months the use of a vibrator, should be examined for the case of oil, such as grease, become dry, or have a hard time, it should be cleaned immediately, replacement of lubricating oil and grease.The bearing should be washed once a year.
