Ⅳ. Installation

1、Installation datum hole

Figure2. datum hole

2、The installation should be based on formation, firmly. Equipment installation at the end of 6-M16 foot pads correction with the level of Department to ensure that the level of the state machinery at the bottom, and then fastening nut anchor bolts. 

3、 In order to facilitate maintenance and inspection, the machine is not less than four weeks should be 1m left of the space. 1.5m above the machinery space should be left in order to replace the bearings when the machine spindle can be removed from the top of the vertical. Figure 3.

Figure 3. Installation space of equipment

Ⅴ. The boot preparation 
1, open the side of the machine base plate, according to the following checks: 
(1) check the Triangle will be tight round the bolt, and each round of V-belt in the correct location. 
(2) to check the degree of tension of the Triangle. 
(3) Triangle with his hands moving slowly round plate, check whether indoor roller white foreign body, especially the metal debris. If so, be clear. 
2, so that under no-load motor operation, according to the following checks: 
(1) motor rotation direction, down from the previous observation, running clockwise Pulley. 
(2) whether there is any abnormal noise machines and vibration. 
(3) whether the overheated bearings throughout. 
(4) whether the motor ammeter showed abnormal

3, air-conditioning 
Equipment in the near vicinity of the wind pipe (see Figure 4), the user network to install wind suction bran should be made for air-flow valves. No-load test, the regulation of air volume, so that pressure gauge shows the value of the machine in the water column -100 ~-150mm range

Figure 4

Ⅵ. Operation

1, After the boot prepared , the startup procedures are as follows

  Start bran-suction fan     （be attention to the air volume）

2. Adjustment of the clearance in whitening room 

The whitening pressure of whitening room in this machine is adjusted by the clearance between huller blade and sand roll ( Figure 5)

Figure 5. The clearance of huller blade and emery roll

Due to sand abrasion and the need to adjust the roll clearance can be removed to build the frame and the side cover, remove the screen and the framework (see Figure 6). Knob and then release the lock nut and rotating the knob to adjust the clearance between huller blade and sand roll. Increasing clearance clockwise rotation, counterclockwise rotation decreases clearance that can be used to check special 6mm feet measured (see Figure 7)

Bearing 

Rotation, respectively, all parts of the machine, check whether there is any abnormal sound. 
Continuous operation for more than 10 minutes to check whether the site bearing abnormal temperature rise. 
   The anomaly of the bearings, should be replaced 

Weekly

Huller blade

  Wear a huller blade above 1 / 3  should be replaced

Every 3 months

Screen

  Broken or deformed should be replaced

Every 3 months

Sand roll

  12mm diameter Emery roller weared should be replaced

Every 3 months

Ⅷ. Replacement of wearing parts

1. replace Screen(see figure 6)

（1）unload the covers;

（2）take off 3 Screen-Frames;

（3）loose the plate of frame;

（4）unload the Screen-Frame； 

（5）replace the sieve。

2. replace emery roller

After unload the Screen-Frame:

(1). Unload the flowrate controller

(2). Screw off the bolt , take off the thruster ( see figure 8)

(3). Take off the roller one by one. Then replace it

Figure 8. unloading of Emery roller

3. Replace huller blade (see figure 9)

Unload 3 sets of Screen-Frame covers first,

• （1） Turn off two knobs； 

（2）unload the base plate，repalce the huller blade。

resolution

Flow rete decreasing

• 1、 Feed valve blockage
• 2、 Thruster wearing；
• 3、 Emery roller wearing； 
• 4、 Huller blade wearing；
• 5、 V-belt creep。

• 1、 Clean the foreign matter；
• 2、 Replace wearing parts；
• 3、 Replace Emery roller；
• 4、 Replace huller blade；
• 5、 Increase tension of V-belt

Broken rice increasing

• 1、 Low quality of material；
• 2、 High pressure；
• 3、 Clearance to small；
• 4、 Emery roller wearing

• 1、 Decrease flow rate&steelyard weight
• 2、 Decrease steelyard weight；
