Small crusher is characterized by small size, low noise, easy to use and a wide range of crushing, it is because of these outstanding characteristics are recognized by everyone, and it is precisely because these characteristics just meet the requirements of family use so gradually into the family. With a small crusher to deal with some daily Chinese herbs or grains effect is very good, here I give you a brief introduction to some of the knowledge about the home crusher and common fault treatment methods, hope to help you correctly understand and choose this novel home machinery.
The so-called small mill generally refers to the operation power of less than 2 kilowatts, small volume, desktop or mobile mill, according to the application of different names are also different laboratory mill, Chinese medicine mill, household mill, etc. The pulverization method of the small crusher is through a closed grinding tank high-speed rotation of the angular blade through the lower part of the grinder motor shaft directly driven, the material in contact with the high-speed rotation of the grinder blade is broken by impact, to achieve the purpose of the crusher. Generally speaking, after the use of the crusher for a period of time, because the seal of the upper bearing part of the crusher will slowly produce a gap with the use of very fine dust into the motor bearing, causing the noise and vibration of the crusher to increase, and the temperature to rise rapidly in a short time. In practical applications, because of the use of ultra-high speed DC motor, the heat is also high, the main heating part is in the carbon brush and commutator and tank, the carbon brush contacts the surface of the commutator in the energized operation of the motor, the power supply outside the motor (generally DC excitation current), through the slip ring (on the rotor, with the rotor running together), Provides to the rotor winding (field winding)., the role of current reversal, so that when the rotor rotates, the inflow of direct current from one end of the rotor to keep flowing, so that the motor rotates in one direction. The carbon brush is in good contact with the rotor of the motor, and the carbon brush is connected with the power supply to provide electrical energy for the rotor. Because the carbon brush is in contact with the commutator for a long time, it produces wear, when the length of the carbon brush reaches the point where it needs to be replaced, the supporting spring behind the carbon brush will no longer work, which may cause poor contact between the carbon brush and the commutator, and the situation that the mill is powered on does not start, when these problems are encountered, as long as the new carbon brush is replaced, the rotor head can be cleaned with alcohol. In practical applications, the push-button switch will also cause the internal power contact ablation of the switch due to frequent stop, when one of the contacts inside the power switch occurs after poor contact, the crusher will not start again after pressing the button on the switch box, these problems can only be replaced by the switch box to solve. The power cord of the small mill has two connections, one is that there is a 3-pin power cord jack on the power box of the mill, and we only need to insert the power cord allocated in the mill accessories into the jack; Another connection is to introduce the power cord directly into the power box of the crusher, so that you do not always have to worry about one end of the power cord loosening. As a crusher commonly used in laboratories, clinics and homes, small shredders have been known for their ease of use and reliable quality.
