The use of bucket elevators attention


In order to better enhance the life of the machine , reduce maintenance costs and improve the use of personnel safety factor , bucket elevator is used to note:
1 , the operator must comply with the "no -load starting , no-load stop " principle. That is the first boot, to be operating normally , give the material ; parking in front of the material inside the machine should be emptied .
2, the work , the feed should be uniform discharge pipe should be smooth in order to avoid congestion. If the issuer blockage, should immediately stop feeding and stop, pull the base flapper , remove the blockage . Note that this time can not directly hand into his base .
3, the normal working hours , the hopper should be in the barrel with an intermediate position , if there is deviation phenomenon or bucket belt is too loose and cause friction collision hopper and barrel , it should promptly be adjusted through tensioning device .
4 , to prevent large foreign matter into the base, so as not to bash hopper, Bucket Elevator affect normal operation . No delivery by the beginning of cleanup materials, feed inlet mesh grilles should be added to prevent the rice straw , wheat straw , rope and other fibrous impurities into the wound caused by blockage base .
5, such as sudden downtime should be first base material accumulated in the discharge and then boot .
    6 , should be checked regularly to enhance the tension level with hopper , hopper and the hopper is firmly connected with , if found loose, fall off , hopper skew and breakage , should be promptly repaired or replaced in order to avoid more serious consequences .

Mill operation and routine maintenance

The role of the Flour Mill at the heart of the production line , so the mill operation and maintenance management level is directly related to the level of mill performance of the play, determines the quality of products, flour yield , yield and other technical and planning indicators , and will affect the labor intensity of various positions .
In the same production line , different operators have different results . Seen, workers in the flour milling important role in the production process .
1, to improve the level of milling machining operations are key to the production of flour .
With the continuous development of science and technology , flour production technology and production equipment and more advanced . But even the best production technology and production equipment also need people to operate , requiring both to understand the principle , but also practical experience of the operator , according to raw materials , milling processes, the technical characteristics mill , accurate adjustment of powder Road , proficiency in various systems mill, milling to achieve the desired effect .
2 , determine the appropriate Ⅰ B traffic is the most important part of production operations
3 , Roller Mill operation from regulation is the focus of the entire production
Rolling mill from regulation, is the most important operating mill content. In actual production , road and roller flour technical characteristics are generally relatively stable . When the quality of raw materials , climatic conditions and grinding teeth old situation changes , you need to adjust the rolling distance or Ⅰ B flows with adaptation , so that parameters of each product is always in coordination stable state.
4, in the mill operation, the higher quality of the operating personnel , skilled skills , fine equipment maintenance is the key to produce high-quality flour , these aspects are interlinked and mutually affected.

Mills describes the mechanical structure

Grinding and Fluting Machine from the power , feed , milling and separation of four system components ; wherein the power system including motor , pulleys , belt, composed of spindle and spindle pulleys ; feed system consists of hopper , limited edition plate and the feed tube ; grind by the grinding mill system composed of body and legs ; separation system consists of a brush mounted on the spindle with the spherical snare Rhodes, and compression screw and mounted on the bottom of the mill body Lo rack components. Grinding machine is available in fixed cone mill grinding grinding grinding flour and dynamic alveolar end mill ends , the increased thickness and grinding teeth around the same height as the plug. Thus, in the grinding teeth are not fully broken particles can pass from the plug from the plug through the powder has been further polished , thereby improving the ratio of wheat flour , flour quality and the efficiency of grinding , and grinding teeth easily damaged .
    Grinding machine comprises a frame and mounted on the base of the power shaft and connected to the power shaft , and with a feed port of the mill with grinding cone, the technical scheme is : the power shaft along the axial direction of the mill is provided with cone grinding gap adjustment mechanism . Food to be processed according to the particle size ( such as corn, wheat, etc. ) and processed food to adjust the thickness of the different requirements , to meet different user requirements. Centrifugal unloader housing upper side has a feeding tube , centrifugal unloader housing located above the wind pipe, centrifugal unloader housing side with trash mouth, the mouth has a mesh trash , the outer screen has a lid , provided below the discharge port switching valve miscellaneous impurities discharge pipe connected to , the ability to fall together with the dust particles of food debris completely removed , the manufacturing cost is low, with low energy consumption .
