Hollow Bricks Making Machine with Reamer Diameter 400/400 MM, Max Extrusion Pressure 2.5 Mpa

JKR40/40-25 brick machine extruder is mainly used in brick and tile factory to produce bricks and tiles and other clay products. It is also used to produce ceramics. The processed pug is changed into the needed billets by the

machine through the following steps. It is mixed first, next treated by vacuum,then conveyed and squeezed by spiral reamer, finally extruded by a fixed shaped opening. The extrusion pressure is very big and the biggest one is

2.5Mpa. Its yield is very high, 8000 to 12000 pieces every hour. Hollow bricks making machine has the reasonable structure and saves energy and is environment friendly.

The main components are reducer, pneumatic clutch, gear box, stirred tank, vacuum box, and mold. The body of JKR40/40-25 brick machine extruder is all made of welded steel plates Operation and Precautions of JKR40/40-25 Brick Machine 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.

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 hollow bricks making 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.

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 hollow bricks making 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:

JKR40/40-25 brick machine 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.
