Advantages (4) BLT type plate conveyor scales
① walking round slat device built double bearing, low running resistance. As plate width is 1000mm B with old scales board machine , walking wheel diameter D = 180mm, try
running side drag coefficient is 0.13 . BLT series of walking round diameter D = 110mm, testing the drag coefficient is 0.03 .
Run the drag coefficient is reduced by 75 %.
② left and right traction chain and bolted tank , do not use common through shaft , reduce weight . For example plate width B = 800mm, P = 315mm chain link conveyor scales ,
can save steel 30Kg / m. Since the left and right through the shaft without traction chain associated , respectively, with a double tail two sprockets
A rolling bearing fixed on the shaft , a traction chain is only S / 2. S is the total traction. A connection form of the original chain traction should be considered 75% -80 %
of the coefficient of unbalance , the actual traction chain BLT series connection form than the original 20% -25 % .
③ scales board tank made of sheet steel wavy structure , thickness is thinner, use the triangle strengthening ribs and angle , so that the tank light weight, rigidity and
impact resistance. For example, the same as B = 1000mm scales board, old scales board weight is 324Kg / m, while the BLT -type scales board only 175Kg / m, saving
Steel, but also reduces the daily energy consumption .
④ walking round with traction chain arranged separately , easy installation and maintenance scales plate device.
⑤ reducer ratio YX driving device , output shaft allowable torque, it directly through the Oldham coupling with
Head axle joints, the head wheel device and configuration of the entire drive system performance greatly simplified , low cost, easy to install.
⑥ tail wheel tensioner two double sprockets are supported by the end of the axle rolling bearing , not only can reduce the resistance of the drag chain to bypass the rear
sprocket , and two traction chain when not synchronized , the chain can be adjusted automatically .

Screw the daily operation and maintenance
Screw conveyor is used to seal conveying powder, granular, small block materials, general purpose conveyor , screw conveyor is widely used for different purposes in
different sectors as may be working Telescopic conveyor in a relatively harsh environment areas, such as the kinds of bearings are in the dust
Work, working conditions in such reasonable operation and maintenance of the screw conveyor on greater significance , the main requirements are as follows :
1 , in the use of the normal operating procedures to operate, and often observe the screw conveyor is abnormal condition exists. If there is an abnormality please shut down
for inspection, screw conveyor troubleshooting before operation.
2, please pay attention to safety , do not place your hands or other objects into the rotating parts .
3 , during use , screw conveyor is strictly prohibited heavy start , start feeding should be preceded by the host , and then feeding ; should be checked before the start of
the cylinder body I is too much material .
4 , in order to ensure that the requirements of the screw conveyor without load starting , conveyors feeding should be stopped before stopping , and other material inside
the chassis rear was completely lost all stopped .
5 , in strict accordance with the mixer loading capacity : no more than the effective volume of the mixer used under strict overload use , it would burn or damage the gear
motor and other components . After adding the material must remember not to stop halfway , try to avoid overloading the next start-up.
6 , the initial feed screw conveyor , the feed rate should be increased gradually until it reaches the conveying capacity , feeding should be uniform, or likely to cause
transport of materials product plugs, drive overload .
7 , the material being transported shall not be mixed with chunks of hard materials to avoid causing death card spiral screw machine damage.
8 , the normal operation of 1800 hours conveyor should be a small repair , mainly to check lubrication or replacement of wearing parts ;
9 , the normal operation of 4000 hours or so should be overhauled , mainly for all assemblies demolition inspection and cleaning, replacement or correction of all wearing
parts and standard parts . When removing the screw conveyor please remember the clear sequence for assembly in the reverse order can be combined . Host computer
Helix and direction of rotation of the feed screw should follow the direction signs, strict reverse direction !
