MDF Board Production Line Welcome Wholesales Crazy Selling MDF Chipboard Production Line Price

This productiong line consists of five technology process flows:

 

1) Chip preparation section   

Wood, branches and wood residues are cut into chips of definite size. Chips from chips silo will be 
screened to remove fines,soil and stones.

2) Fiber preparation section  
Chips are transported to upper bin of refiner, and positively fed to 
digester by screw feeder for steaming. Steam chips will be distintegrated to fiber under the force 
of heat and mechanism. Mix dryingmedium and wet fiber which is in the state of suspension with 
the help of high pressure airflow,and thus exhaust moisure in fiber via drying medium to ger dry fiber.  Dry fiberfalls on belt conveyor through cylone discharge valve, and then be transported to dry fiber 
bin for storage.           

3) Glue mixing and applying section         

 Process of glue applying before drying is adotpted.Feed molten paraffin and water-proof additive to fefiner. Paraffin is mixed with fiber uniformly under the force of refiner plates. 
Glue is transported to the below line of fiber discharge valve. With the help of 2830m/s high 
speed air flow,glue mist meets and attachs to the surface of fiber. This section can be 
controlled by PLC or computer.
 

4) Mat-forming and hot-pressing section

The fiber after drying is transported to the above of forming machine, and uniformly spread onthe 
conveying mesh belt in the way of air-flow.Vacuum box equipped below the mesh belt 

provides negative pressure and air will be removed via mesh belt,fiber stays on mesh belt and 
thereafter forms mats gradually. Fluffy mats will be pressed by pre-press. Pressed mats are cut into definite length by longitudinal and transversal saw, then 
transproted to loader passing 

through accelerating conveyor, stoage conveyor and extension conveyor. When finishing loading 
mats,carriage in the loader will feed conveying belt and mats into hot press,at the same time, 
shovel head at the front end of conveying belt pushes out pressed board.When carriage coms to 

terminal,boards have been into unloader,and mats also arrives to due position.Carriage returns,
conveying belt turns forward. Mats are in relative still state and stay on the platen of press when 
velocity of conveying belt is the same as the returning  speed of carriage. Glue in the mats cures ,
thanks to temperature and pressure in hot press, and hence boards with definite intensity and 
thickness form. Rough boards will be put on support via loader. Outfeeding conveyor will unload 
boards one after another to next section when cage comes down.

5) Cooling, sizing and sanding section

Rough boards after air cooling are turned in to cut-to size boards via longitudinal and transversal saw. And then cut-to-size boards are sanded, sorted, stacked and packed for sorage.

Extruder maintenance equipment

Ensuring the feed screw and barrel remain in top condition is an essential part to achieving processing goals. Over time and under continuous operating conditions, the feed screw and barrel will experience wear. You will need both cleaning tools and measuring tools to ensure accuracy of your measurements. PromaXX provides Maintenance Equipment to our valuable customers in the daily maintenance of Feed screw and Barrel.
