3.3.2 The former approach must has complete cleaning, destine, magnetic separation, husking and paddy separation. The impurities, stones, metals mustn't enter in the whitening chamber in case any damage to the machine.
3.4. Installation method
3.4.1 Installation of main body
a)Put the machine on required the place, fix the machine by 6 foundation bolt M16, check if the machine is level, if not use spacer to leveling and tighten the bolts avoiding the noise. See the pic below
b)To make it easy to move and exchange parts, leave enough space(especially leave space for exchange main axle and bearing).


3.4.2 Installation of electric control
a)Put the electric box at appropriate position, close to the main body. Connecting the wires by present regulation.
b)Use 16mm2  copper wire.
c)The motor must under protection of overload and low-voltage, with reduction voltage starting.
d)Equipped with starting, stop switch and ampere meter. Specific value is 150:5(when use 37kw motor) and 100:5(use 30kw motor). Please choose current transformer accordingly.
e)Working time counter is recommended to maintenance timely.
DANGER Mustn't use worn wires.
Electric leakage can cause damage to goods and personnel
3.4.3  Chute installation should be workable, easy to maintenance and beautiful.
3.4.4 Installation of air net for bran collecting
Air blower 9-26NO-4.5A is recommended, the air net installation is suggested as follow

3.5 Checking power source
3.5.1 before connecting, make sure the voltage of machine is same with power source
3.5.2 after connecting wires, make sure it on correct connector
3.5.3  machine must has ground connection to avoid electric shock
3.5.4  this action must be done by qualified electrician

Chapter IV  Operation
4.1. Operating position
4.2. Preparation before Switching on: the follow steps must be taken especially before the first starting
4.2.1 Machine must be installed and connected according to the regulation.
4.2.2 Check whether the bolts and nuts are tightened up and whether the tension and parallelism of V-belt are proper.
4.2.3 Check whether the opening and closing adjustment of feed hopper and pressure door is flexible.
4.2.4 Check is the rotate direction of motor if correct ( faced with feeding port, the correct direction is clockwise).
4.2.5 checking if there is below situation when running without material
a) the temperature of bearings must be lower than 30ºC
b) If there is abnormal noise or vibration
c) If the electric current is normal
d) Check if there is vibration at ground, if yes, leveling each foot by iron rod.
4.2.6 Adjustment of air volume
      When running, the air suction volume should be about 2000m3/h in order to clean all bran.
4.3 Start and shut down
Start: start the posterior host--------start main machine-------running without material(test run)----------open feeding board--------adjusting flow------adjusting pressure gate
          When working, don't put anything on the machine.
         Shut down: stop posterior host-------close feeding board---------open pressure gate-------shut the power-------open access door-------clean
    4.4 Operation
4.4.1 Adjustment of feeding flow
If test-run is normal, put the pressure lump at the bottom, open the feeding board, fill the whitening chamber with material. When it starts to outletting stabilize the electric current and adjusting the flow, observing the ampere meter. Adjusting the whitening degree according to the rated current.
Notice: the actual current can't over rated current and it can't run full load too long.
4.4.2 Adjustment of whitening degree and broken rate
Usually, whitening degree is in direct proportion to broken rate, high whitening degree then more broken; low then less broken. After start the machine, when current is stable, whitening degree can be changed by adjusting the pressure lump.
Whitening degree also can be changed by adjusting the mobile blade, but this action must be done when the machine stops and the blade can above the screen for 1.5mm at most.
4.4.3 Adjustment of tightness of belt
To adjusting the tightness of belt by changing the position of motor plate.
Chapter V  Maintenance
5.1. Maintenance
    5.1.1.Check fastening of bolts and tension of belts regularly.
    5.1.2.Regularly replace lubricating oil and grease.
5.1.3. The outlet, Bran suction chamber, feed chute and Bran Suction pipe are places which accumulate bran and should be cleaned periodically.
5.1.4. Regularly check the following items
ItemsDescription Frequency
Overheating of Main BearingTouch the bearing block to check overheating after running for 10 minutes. When overheating detected, remove and check. Replace it if necessary.Weekly
Abnormal NoiseRun each units separately to exclude abnormal noises before starting.Anytime
V-belt tightness Press the belt by hand, if it can be pressed down 20mm, the V-belt tightness is appropriate Weekly
Sieve WearingUsable unless broken or deformedWeekly
Bran Accumulation inside the machineClean interiorsweekly
Bran accumulation in the bran pipeClean the bran in the bran pipePeriodically
Caution Maintenance and examination should be conducted only after the machine stops completely. (The spindle may run further for about 3 minutes after switching off the machine.)
5.2.  Replacement Sequence of easily worn Parts
5.2.1. Procedure of replacing sieve
Unscrew M10 bolt on the mobile deck support,
When exchange new sieve, please remove the grease.
5.2.2 Changing screw and emery roller
a)Open the access door on both sides, take away mobile deck support, remove the sieve.
b)Disassemble the locknut and lock washer.
c)Unscrew 6 screws M16, and remove the outlet bearing base by 2 threaded rods with length over 60mm.
d) Take away axle sleeve, feeding dial, emery roller and screw and install new ones.
5.2.4 Notice when reinstall
    a),Don't forget flat key when install screw and emery roller, and notice the installing order.
b),If there is blur between rollers, roller and screw, should remove the blur. The connecting point of each part should be smooth to avoid broken.
c),When replace parts of whitening chamber, must remove the blur that might cause broken.
5.3  Machine lubrication
5.3.1  Cycle
The lubrication of machine shall be carried out by fixed staff on a regular basis; the maintenance may be conducted at the production gap; it is required to lubricate the bearings every six months.
5.3.2  Lubricant product
Use the generic lithium-based grease; do not mix different types of lubricants to use after having chosen a certain type of lubricant, because this will reduce the service life of related components and affect the normal operation.
5.4  Check the tightness of fasteners
5.4.1  Inspection cycle
Check the degree of tightness of bolt and nut. Check one after 8 hours of work, and later fasten all for every 2,000 hours.
5.5 Trouble shooting
FaultPossible CausesRemedies
High percentages of broken Poor quality of raw materials
Screen blade is too thick and the shape edges have not been chamfered
There are burrs inside the whitening chamber The rotating speed is too high
Remove sharp edges and burrs
Replace motor pulley with small one

Abnormal Vibration
Fasteners loosing
Unbalances caused by uneven wearing of emery roller, Screw thruster or feed dial roller
Bearing wearing
Supporting points of machine do not touch the ground due to bad foundation level, 
Tighten all fasteners
Replace new spare parts
Replace the bearing
Shim and fasten the anchor bolts
Poor PrecisionParts wearing in whitening chamber(Emery roller, Screen blade ,etc)
Input too much
Belt slipping
Replace with spare parts and adjusting Screen blade
Adjust the Input
Tighten the belt
