Technical Parameters:
This equipment is for vacuum extruding and molding the products of fired common brick, fired perforated brick, fired hollow brick, hollow block and etc.
Our extruder has three forms: soft plastic vacuum extruder, semi hard vacuum extruder and hard plastic vacuum extruder.
Soft plastic vacuum extruder is suitable for the raw materials with moisture content higher than 19%;the allowed extrusion pressure is 2.0MPa.
Semi hard vacuum extruder is suitable for the raw materials with moisture content between 16%~19%;the allowed extrusion pressure is 3.0MPa.
Hard plastic vacuum extruder is suitable for the raw materials with moisture content lower than 16%;the allowed extrusion pressure is 4.0MPa.
How to operate clay brick extruder correctly?
①Release the clutch before turning on the switch. Start the motor, then slip the clutch in when motor reaches normal speed. Feeding speed is supposed to get the vacuum chamber running smoothly, not blocked. And it is strictly prohibited to start with load.
②For clay brick extruder in normal production, start vacuum pump firstly, and then start clay brick extruder when the reading of the vacuum gauge reaches required level.
③Release the clutch, then turn off the motor before stopping the machine. For stopping vacuum brick extruder, close upper stage --mixer part firstly, then lower stage--extrusion part. If the machine needs to be temporarily stopped, it is only necessary to release the clutch device, no need to turn off the motor. Stop adding and squeeze out the mud before stopping extruder. Turn off the vacuum pump when vacuum extruder stops.
④Warm reminder：during operation, you must concentrate on the operation of the machine mouth, pay attention to the mud quality, and take appropriate measures in time.
⑤For vacuum extruder, pay attention to mud condition in vacuum chamber. If there is mud accumulation, you can adjust it by suspending the upper mixer to prevent blockage. Be careful with the degree of vacuum gauge and find out the causes in time if the vacuum does not meet the requirements.
