JKY50/50-40 Brick Vacuum Extruder


A Brick Vacuum Extruder with Reamer Diameter 500/500 MM, Max extrusion pressure 4.0 Mpa The JKY50/50-40 double vacuum extruder is mainly used in clay brick production line. It is also used to produce ceramics bricks. The processed pug is changed into the needed billets by the machine through the following

steps in clay brick production line. It is mixed first, next treated by vacuum, then conveyed and squeezed by spiral reamer, finally extruded by a fixed shaped opening. JKY50/50-40 Brick Vacuum Extruder has the reasonable

structure. Its extrusion pressure is very big and the biggest one is 3.5Mpa. Its yield is very high, 15000 to 18000 pieces every hour. At the same time, it is applicable for high vacuum, squeezing thin-walled and porous shale, and

coal gangue and clay brick. The main components are reducer, pneumatic clutch, gear box, stirred tank,

vacuum box, and mold. The body of of JKY50/50-40 brick vacuum extruder is all made of welded steel plates

Operation and Precautions of JKY50/50-40 Brick Vacuum Extruder:

1. The machine opening, core head, core rod should be replaced and adjusted in time. While they are abraded to some extent, the sizes of tile will be affected in clay brick production line.

2. The wearing parts should be repaired and replaced when they are abraded after a period of use, or the product quality and output will decline, such as reamers, stirring blades and mud pressing board.

3. When you want to stop the machine, stop feeding first, and then squeeze out the clay inside the machine, in order to avoid the overload at next startup. Don't reboot the machine if the air pressure is lower than 0.5MMpa. The friction plate is easily burnt if the air pressure is not enough in clay brick production line.

4. The machine and all the bolts should be stopped and checked after six to eight hours' work for the first time to make sure if there is looseness. If yes, fasten them in time. If the machine is stopped for more than one day, all the clay material should be squeezed and cleaned out, trying to avoid the damage by the dry clay.

Maintenance and Repair:

JKY50/50-40 brick vacuum extruder should be in good water lubrication condition so the machine is enabled to obtain the maximum efficiency and prolong the service life.

Spindle speed reducer is lubricated by an oil pump filled with N150 (GB/T3141) lubricating oil. The better refueling position is between the two scales of oil dipstick. The other parts are lubricated by 3#extreme pressure lithium-based grease (GB7324-94). The filled lubricating oil has to be replaced after 300 to 600 hours at the very start, and then it can be replaced after 1500 to 5000 hours. The lubricating grease has to be filled regularly.
