introduction： principle： The wet material feeder is continuously added to the drying tray of the first layer above the dryer，The rake arm with the rake blade rotates to make the rake blade continuously turn over the material。The material flows through the surface of the drying pan along an exponential helix；The material on the small drying tray is transferred to the outer edge；And the material on the large drying tray moves inward and falls from the middle to the lower small drying tray。The drying pans are arranged alternately up and down，The material can flow continuously

introduction： The key to the operation of the polishing machine is to try to get the maximum polishing rate，In order to remove the damage layer caused by polishing as soon as possible。It is also necessary to ensure that the polishing damage layer does not affect the final observed tissue，It doesnt create fake tissue。The former requires the use of a coarser abrasive，To ensure a large polishing rate to remove the polished damaged layer，But the polishing damage layer is also deep；The latter requires the use of the finest materials，Make the polishing damage layer shallow，But the polishing rate is low。The best way to solve this contradiction is to divide polishing into two stages。The purpose of rough polishing is to remove the damaged layer of polishing，This stage should have the maximum polishing rate，roughing

introduction：Butt bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Periodic inspection，It is very important to keep the bearings in the best condition，It can also reflect the discovery of problems。Matters and relevant knowledge that should be paid attention to in the use of bearings。 First of all，What we want to emphasize is this，Holding inlet bearing[Imported bearing:Simply say imported bearing generation

introduction：jingjie Diametral pitch diametral pitch In English gear，PI and tooth spacing（Sighting module）Ratio of，Diametral pitchP＝/，In order to 1／In inches。conceptually，Diametral pitch is the reciprocal of the modulus in the metric system。Corresponding to the conversion of units，The relation between diameters and modules is as follows P＝/＝25.4/ShizhongPDiametral pitch（1／inches）；pitch（inches）；modulo（millimeter）。Diametral pitchPSimilar to the function of the modulus in the metric system。In most imperial gears、Gear coupling and ratchet and other parts，Diameter pitch is a basic parameter。Greater pitch
