Heavy plate feeder operating procedures and maintenance

Heavy Mobile crushing plant and maintenance procedures are as follows:
A machine is in use should always maintain a certain chain plate thickness of the material , generally not less than 500 mm , not in the emptying state board discharge directly

to the chain . When you can not avoid when emptied , before unloading Lay a layer of debris in the chain plate to prevent the direct impact of the chain plate , when the bulk

material

Clogging material in the form of coal screening machine rows of blasting is not permitted at .
2 machine installation rear discharge opening to the distance between the chain plate , not less than 1.5 to 2 times the largest block of material , to ensure smooth flow of

materials to improve the service life of the chain plate . Steeplechase after installation should be blocked on both sides of the chain plate gap is left between 8-13 mm , Mian

materials to avoid spills, and the resulting material and sideboard

Friction, produce sound , stopped plate chain plate surface with the bottom edge to keep the distance of 5-10 mm , to prevent material spills, tensioning device axis line from

the silo wall should leave some space is generally 350-500 mm , easy maintenance disassembly.
3 crawler chain pitch wear to greater than 7 mm , the sleeve should be transferred to an angle or should be replaced with a new chain.
4 Remove cover up , first loosen all the screws , but do not remove all the screws , remove the galvanized screws and washers , the removed screw into the front of the shop help

pressure ring screw hole , gently tap head make up sets loose, then pull out the screws , pull up sets that followed .
5 Install sets up when the original installation of the joint surface should be cleaned evenly coated with a thin lubricant ( excluding two alumina ) , will set up screw wrench

force away from the cross- check by diagonal evenly tightened.
6 Install bearing spindle device , the minimum radial clearance should ensure that 0.08 mm or so, reduce the amount of radial clearance between the 0.09-0.11 mm can, bearing

tensioning device should ensure that minimum clearance of about 0.55 mm , and its diameter to reduce the amount of 0.06-0.07 mm

Rooms can be.
7 Replace the chain board, chain plates bolted with track links , each bolt tightening torque for the 750-900N.M.
8 The operator should be familiar with the machine's structural principle , each class should be checked before each part operation is normal, chain plate bolts are loose , the

examination was normal before starting operation .
9 . Properly lubricate the bearings and gear , and regularly replaced with new oil.
10 Note Check the chain plate work , especially without loosening bolts to maintain proper chain tension , if found wandering through the tensioning device should be adjusted .
11 does not occur during normal operation and fault sound should stop immediately , carefully examine the causes, discharge failure.
12 In addition to pay attention to the use of routine maintenance , but also regular inspection, maintenance and timely replacement of worn parts.
