Heavy plate feeder operation and maintenance and overhaul procedures

The operator should be familiar apron Vibrating feeder structure and application , each class should be checked before the operation plate feeder parts are normal, chain plate connecting

bolts are loose , no abnormal before starting operation . Here to introduce you to heavy plate Pan feeder in operation England note , and

Its maintenance and repair procedures.
1 Use the board in the chain should always maintain a certain thickness of material , generally not less than 460 mm . The state is not allowed to unload directly to the chain

plate discharge, when emptied can not be avoided when the chain plate before unloading Lay a layer of debris, to prevent the direct impact of the chain plate , when the bulk

material clogging

Is not allowed to use the form explosive discharge ;
(2) Install the rear plate feeder spout top to the distance between the top of the chain plate not less than two times the largest block of material , to ensure smooth flow of

materials to improve the service life of the chain plate . To avoid spills and the materials and materials generated by the friction caused by the sound baffles , guide plate

should be installed on both sides of the bezel with the chain plate

A gap left between 50-100 mm . The bottom edge of the guide plate from the surface of the chain plate maintained at 10-25 mm , to prevent material spills, tensioning device away

from the axis of the silo wall should leave some space , usually 350-500 mm , ease of maintenance disassembly ;
3 apron feeder chain pitch inside track pin bushing wear to greater than 7 mm , the sleeve should be transferred to a new angle or replace the chain ;
4 plate feeder disassembly expansion sets , first loosen all the screws , but do not all of the screws removed. Remove galvanized screws and washers , the removed screw into the

holes before the pressure in the auxiliary ring , gently tapping the screw head , so get moving expansion sets , then pull out the screws , expansion sleeve that is pulled along

Out ;
5 mounting plate feeder expansion sets , should the original installation of the joint surface clean , evenly coated with a thin layer lubricants ( excluding molybdenum

disulfide ) , the expansion sleeve screws with a torque wrench by diagonal cross evenly tighten ;
6 apron feeder unit bearing mounted head , the minimum clearance should ensure about 0.08 mm , radial clearance reduction in the amount of 0.09-0.11 mm can be. Rolling tail unit

should ensure that minimum clearance of about 0.055 mm , the radial decrease in the amount to between 0.06-0.07
