Equipment Summarize

2.0 Summarize GT series dewatering screen is widely used in coal preparation, mineral processing, building materials, construction, electricity and chemical industry products classification purpose, dehydration, tailings recovery. 2.1 Working principle 。GT series dewatering screen has the vibration motor with the same performance parameters as excitation source, when two sets of vibration motor in the same angular velocity do reverse operation, the inertial force produced by an eccentric block in a particular aspect torepeated stack or offset, so as to produce a great shock, driving the screen box along the straight line track to do periodic reciprocating motion, make the materials on screen mesh from input to output to do gradually vibrate, during the vibrating process the part less than the screen hole (water) through the sieve hole falls, the rest from the output falls, so as to achieve the purpose of classification, dehydration.

3.1 Exciter

This machine excitation source is two spindle parallel vibration motor, the two motor reverse rotation, produce the resultant force driving along the straight line screen box track reciprocating motion.

During the Installation or adjustment, maintenance of this department should prevent turning

device wounding ！

The vibration motor ’s every end is driven by a main eccentric block and a rotating vice eccentric block made by adjusting the two eccentric block size to change an angle, then adjust the vibration motor excitation force size, and the vibrating amplitude values (see the vibration motor instruction). Two motor four groups of eccentric angles, and the direction of the eccentric on the motor must be identical

weight plate of four eccentric plate must be same to avoid unnecessary losses！ After adjustment of auxiliary weight plate, must ensure no unimpeded situation of rotating equipment before start！

3.2 Screen box Cabinet side panel is made from quality blending steel, the central space of two side panel is connected with thick-walled seamless steel pipe, steel pipe ends are connected with box side panel by high-strength rivets forming frame type screen box. This structure can ensure the whole rigidity of screen box more solid, and much more difficult to be cracked and so on. 3.3 Screen mesh This machine has the polyurethane frame screen with’ the high wear-resisting blockingproof performance. According to the actual situation the screen hole size could be used by 0.1 2 mm occasions). 3.4 Brackets Brackets is welded by frame steel, which support the weight of entire screen machine and extra work loading. Adjust the relative height of front-brackets, back-brackets for vibrating screen to Lipu heavy industry co.,ltd

change inclination of screen surface.

If need to adjust the angle of the vibration sieve, only need put pad with different thickness under front-brackets or back-brackets.

After adjustment must ensure that two former and latter brackets have the same level height

3.5 Damping device Because of huge exciting force when vibrating works, adopting spring to separate vibrating screen equipment and bottom bracket ,could effectively reduce the vibrating impact on bottom base. 4 Main technical parameter Chart 4.1

5.1 Equipment installation Firstly install the brackets of screening machine on the top of embedded iron based on construction drawing, then place damping spring on the brackets and using lift equipment to lift screening box whose height should be higher than damping spring by 200mm,and then adjust the relative position of screening box and brackets till two units cope with each other completely, finally place screening box on top of spring slowly. 5.2 Equipment commissioning

STOP

To avoid unnecessary losses, must stop machine to do inspection if there is any emergency and exceptions！ Electric wires must be operated by professionals！ Two motor must reverse rotation!

（1）After equipment installation, should check fastening condition of all bolts; Check the relative position of screen box, feed chute and discharge chute to ensure no possibility of collision. （2）Check whether electrical wire is correct. （ 3） In four hours of the test run, vibration motor temperature will be gradually raised, and balance. Usually, bearing temperature rise should be less than 40 degrees. If found bearing has a sharp rise in temperature and must stop to check reasons. （ 8） Check all the fastening condition of bolts for screen machine. （ 9） Check whether there is abnormal noise of the screen,. （10）If there is no exception after 8 hours test running, the screen machine installation should be qualified. 6

Manual

Operators of screening machine should completely know the structure and working principle of equipment. Before starting screening machine, should make good preparation and check the condition of coupling to ensure screen mesh and other parts are in good condition.

6.2 How to start&stop screening machine. Screening machine is generally used in crushing&screening or washing process, and should be starting&stopping based on idle-load, therefore need to comply with reverse-process starting and along-process stopping. Screen machine starts, need to close knife switch, connect wire with grid, then press start button and one-time starting should be done. Except special circumstance, screen machine is not allowed to stop with mineral products. Usually press stop button to stop running of machine.

（1）Checking the accumulation of material, whether form screen box, feeding equipment and discharging equipment collisions. （2）Checking screen surface tightening and wearing condition. （3）Checking whether the screen hole are blocked and the accumulation of material. （4）Checking fastening condition of connection bolts。

（5） When screen operates, check whether products is uniform distribution of screen surface. 3 ）Support device （1）Check whether spring be fracture or broken. （2）Check whether products is accumulated around spring. （3）Check whether compression condition of each spring is uniform. （4）Check whether any cracking of weld connection exist. 7.2 Welding and gas cutting on screen box Generally welding and gas cutting is not allowed on screen box directly；Because welding and gas cutting would produce partial stress which would shorten screen box using life. In special circumstance, welding and gas cutting must be aware of follow：（1）As for cracking condition of side plate, must find the exact cracking end, and drill a hole of 5mm to prevent further expansion of cracks （2）When welding, be sure to make screen welding parts on the ground to prevent electricity current run through bearing. （ 3） Welding parts need warm-up in advance. （ 4） Grinding crack into groove shape, then adopt good quality electrodes for welding and make welding crack polished. （ 5） If must have gas cutting holes on screen box, the edge of holes should be polished, or equipment would be damaged because of intent stress. 8
