4. Installation Guide of Hammer Type Whirlwind Mill
After unpacking, check various accessories and spares against the packing list and the accessories must be mounted on the main machine.
4.1 Place the main machine of hammer type whirlwind mill on a flat and sound
work stand surface.
4.2 Carefully read the operation manual and the operation precautions
printed on both sides of the whirlwind mill.
4.3 Take stainless steel collector (14) and unscrew the fixing screw (12) on the upper side of discharge pipe on right side of main machine. Insert the feed pipe on upper part of the collector into discharge pipe (13), fasten the screws after adjustment of collector angle. Put the air filter bag (11) around the big pipe on upper part of the collector.
4.4 Open the front door (7), loosen the circular connecting nut (3) on the upper of rubber sealing sleeve which locates on the upper part of mill cylinder and butterfly nuts at right side (16). Open the front cover (6) of mill cylinder and check if the mill hammer is loose. Then pull
and hold outer side of blades of mill hammer with left hand and fasten M16 stainless steel nut on the center shaft clockwise by means of a spanner with right hand. Check the size of screening plate (a screening plate with hole size Æ0.8mm is mounted when delivered). Close the front cap (6) of mill cylinder and fasten butterfly nut (16) and circular nuts (3), then close the front door (7).
4.5 Check if the voltage of power supply meets requirement and then connect the plug with power supply socket.
4.6 Check if the rotational direction of mill hammer is in coincidence with that pointed out by arrow on the front cover of mill cylinder (counter clockwise).
4.7 Pull down the spring clamp (15) of the collector with left hand and take out the sample cup on lower part of stainless steel collector with right hand. Then pour out the foreign object in the cup and lightly rotate it several times leftwards and rightwards after replacing it back to prevent leakage.
4.8 Install the transparent feed hopper into feeding head (10) and press it soundly. Totally open adjustment plate (2) of stainless steel throttle valve.
4.9 Press the green start button (8) on lower left side. For the first time application, let the motor running idly for 2 to 3 minutes.
4.10 Press the red stop button (9) to stop the machine.

5. Operational Guide of Hammer Type Whirlwind Mill
5.1 Before operation of hammer type whirlwind mill, it should be confirmed that the operation voltage is AC 220 ± 10 V with frequency 50 Hz. The current capacity of power supply socket should be equal to or greater than 10 A.
5.2 Before putting sample grains into feed hopper, it should be confirmed that there is no small metal pieces or other hard object within the sample grains.
5.3 The hammer type whirlwind mill should be placed on clean, dry, well ventilating, level and sound stand to ensure normal running of the equipment.
5.4 After connecting to power supply, the start button should be pressed only after having adjusted the throttle valve on feeding head to the maximum position. After normal operation of the whirlwind mill, pour the sample grain into feed hopper and then adjust the throttle valve to let the sample grain gradually enter into mill cylinder. The entering speed of grain should not be too fast, to avoid the blocking operation.
5.5 After having pulverized the sample grain, let the mill operate with time delayed for 40 to 60 seconds to clean the mill cylinder automatically, and then press the red stop button to stop the mill.
5.6 The quantity of pulverized sample grain for each time is 200 to 300 g.
5.7 The feed speed could be adjusted by the adjustment plate of throttle valve on the feeding head. The feed speed depends on water content within the sample grain. The greater the water content in the sample grain is, the slower the feed speed should be. For 300 g of wheat grain with standard water content, the normal pulverizing time is about 90 seconds. If there
is abnormal sound from the motor, it means the feed speed is too high.
5.8 For sample grain with high water content, the feed speed should be very low. Otherwise, the dough would be burnt due to high temperature within mill cylinder. If this phenomena has happened, the mill cylinder and whole powder discharge duct should be cleaned immediay.
5.9 If an automatic feeding device is used, the feed quantity of sample grain could be adjusted by the speed regulator, so that the necessity of controlling feed quantity of sample grain by means of manual adjustment of throttle valve could be totally excluded.
5.10 After finishing pulverizing of sample grain, the upper part of collector must be beaten several times with a small wood stick. Then take out the sample grain cup and screening and weighing as required.
5.11 If falling number or the index in relation to water content is measured, the weight measured by means of scale must be corrected to that at the standard water content.
6. Description of Circumstances where the Hammer Whirlwind Mill is not Applicable
6.1 The hammer type whirlwind mill is not suitable to be applied to pulverize sample grains with high water content, high viscosity, high oil content and high cellulose. Otherwise, not only the pulverizing effect would be not satisfactory, but also the machine would possibly be damaged and even motor could be burnt out.
6.2 A single phase capacitor started motor is used on the hammer type whirlwind mill and its output power is 750 W. It cannot be used to start with load and for long time full load running. Otherwise, the temperature within mill cylinder would rise rapidly, or the motor would be damaged due to overloading.
6.3 The hammer type whirlwind mill is not applicable to pulverize the sample grains with high hardness, large size or irregular form. If such sample grains must be pulverized with the whirlwind mill, they should be first processed by preliminary pulverizing and then pulverized by the whirlwind mill.
7. Trouble Shooting of Common Failures, Service and Maintenance of Hammer Whirlwind Mill
7.1 Cleaning
If abnormal sound or low powder output efficiency (powder output lasts for long time) is heard or observed during the application process, it means that the machine should be stopped for cleaning. The cleaning should be done as following:
7.2 Replacement of Screening Plate
7.3 Replacement of Mill Hammer
If the mill hammer is worn out seriously or deformed under the effect of a force, it should be replaced according to following procedure:
7.4 Locking up and Replacement of Driving Belt
After long term operation of hammer type whirlwind mill, the driving belt would definiy elongate and be worn out, resulting in slipping of belt or low working efficiency. At this time, it is necessary to adjust belt tension or to replace the driving belt as following:
7.5 Start failure
7.6 Tripping of internal heat protector within motor due to overheating of
the motor
Wait for some time and restart the motor after it is cooled down.
7.7 Burning out of Motor due to Overloading
Remove the motor and send it to the Company for repair.
