1. General Description of Operation Principle of Hammer Type Whirlwind Mill
When making physical inspection and chemical analysis of the grain quality, the grain departments normally pulverize the sample to be measured and detected.
JXFM110 model hammer type whirlwind mill is developed and produced by Shanghai Jiading Cereals and Oil Instruments Co. Ltd. (hereinafter referred to as the Company) under the cooperation with China National Cereals and Oil Quality Supervision and Inspection Center. The company has absorbed advantages of same category of foreign products, so that the product becomes a crushing equipment which has features of smart appearance, compact structure, convenient operation, stable running and long service life. The mill is suitable to be used in grain processing industry for pulverizing of intermediate and small size grains, such as wheat and rice with water content that meet national standards. The mill has following features:It can pulverize various grains with high efficiency and high speed. The sample grains are pulverized by means of high speed mill hammers (16800 r/min) into fine and uniform powder which enter into a stainless steel collector through a screening plate and then is fabricated into a sample powder.On the inner wall of the tank there stacked with a layer of domestically advanced sound absorbing material which makes noise to be lower than that of the same domestic and abroad products.There is an embedded temperature protector within the motor. Once the temperature of motor exceeds a set temperature limit, it would automatically stop running and start again when the temperature decreases to the normal value below the limit.The high speed air flow produced during pulverizing sample grains has a self cleaning effect. Therefore, no manual cleaning the mill cylinder is required generally during the interval between sample pulverizing operations.After going through sieves with different screening hole sizes, the pulverized sample powder is suitable for samples preparation and measurement and analysis of their various indexes, such as wheat gluten quantity and quality, falling number, near infrared compositions, grain viscosity and other fineness requirements etc..For large grain samples of irregular form (such as maize grains), a preliminary pulverizing by means of laboratory pulverizing mill or direct feeding pulverizing is required.The high speed air flow produced during hammer pulverizing could result in loss of water content in sample grains. Normally, a sample grains that contain 10 20% water would loss 5 10% water content during the pulverizing process.

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.
