It is suitable for desilting, desilting and desilting of tailings. Dewatering screen for dry discharge of tailings It is mainly used in tailing dry discharge and other technological processes, and the effect is extremely obvious. It is the landmark equipment of new generation tailings dry discharge.
Double motor self synchronization technology, universal eccentric block and adjustable amplitude vibrator are adopted in the dewatering screen of tailings dry discharge. It is mainly composed of screen box, exciter, supporting system and motor. Two unconnected vibrators operate synchronously and reversely. The centrifugal force generated by two groups of eccentric masses is superposed along the vibration direction and counteracted by reverse centrifugation, thus forming a single exciting vibration along the vibration direction and making the screen box move in a reciprocating straight line.
1. The vibration motor of the dewatering screen is easy to replace. The rubber spring on the base is used to reduce the vibration, so that the vibration amplitude is small and the vibration is slow, and it can be removed clean.
2. It can be customized according to the output and water content. The side plate of the fuselage has a reinforcing plate, the bottom is equipped with a support, the bottom is made with a horizontal bar, and the outlet is supported by a triangular steel plate. The plate is thick,
3. The vibration motor is fixed by high-strength bolts, and the bottom spring is rubber spring. The quality of the spring will affect the service life of the vibration motor. The density of the sieve plate is high, and there are reinforcing ribs in the sieve plate,
4. After welding, the welder shall strictly avoid welding holes, and the bottom shall be supported by channel steel.
5. In addition, the screen hole can be adjusted according to the needs, the equipment noise is small, and the dehydration effect is good.
6. Before delivery, the staff will debug it, whether the vibration motor is normal, whether the exciter is in good operation, to ensure the quality of products delivered to customers.
7. Additional value of dewatering screen: for products with low mud content, dehydration screen can be directly used instead of sand washing machine, which can save the cost of customers and achieve the same effect.
Tailing dry discharge dewatering screen is widely used in tailings dry discharge, concentrate dewatering, slurry concentration, chip removal, carbon slurry separation and other filtration and dewatering equipment industries. This machine is especially suitable for processing fine-grained minerals. It can also be used in combination with hydrocyclone. It can be widely used in tailing dry discharge and concentrate dewatering.
The successful application of tailing dry discharge dewatering screen can not only improve the safety and reliability of existing tailings dam, prolong the service life of existing tailings pond, solve the problem of long-term storage of tailings, but also play an important role in accelerating the popularization and application of the technology.
matters needing attention
(1) During the operation of the vibration motor, attention must be paid to the lubrication of the bearing. Under normal working conditions, the bearing grease should be replaced and the bearing, bearing chamber and bearing gland should be cleaned.
(2) After the motor is out of use or stored for more than half a year, the motor should be disassembled for maintenance and replaced with grease.
(3) After the accumulated operation time exceeds 5000 hours, the motor bearing shall be inspected. If it is damaged, the bearing shall be replaced with a new one.
(4) After the dewatering screen is stored for half a year or a long time, the insulation resistance of motor stator coil to ground shall be measured before use. When measured with 500V megger, the insulation resistance shall not be less than 20 megohm.
Before starting the machine:
(1) Check whether the fine mesh and coarse mesh are damaged
(2) Check whether the transportation support is removed.
When the machine is started:
(1) Pay attention to abnormal noise
(2) Is the current stable
(3) Is the vibration abnormal
After using the machine:
(1) Clean up after each use. Maintain regularly.
(2) Regularly check the coarse mesh, fine mesh and spring for fatigue and damage, whether the parts of the fuselage are damaged due to vibration, and the parts requiring lubricating oil shall be lubricated.
