Installation story in South Africa-pallet block

Sawdust pallet block production line installation in South Africa(1)

This article is based on my real experience. 
And for better explaining all details, please allow me to add other clients' installation story to give more information on

-Instructions of installation;
-What engineers will do in installation;
-How to maintain a production line.
-Local beautiful scenery.

Gates of memories will never close...

In June, 2016
Our engineer, Peter, our engineer and I were invited to South Africa to install one sawdust pallet block production line. The client, King (not real name), and his wife came to visit us in 2015. And we had a happy time together in China and built trust with each other until now we still have a good relationship and I hope it will last forever.

This installation lasts from Monday to Thursday. 
It is fast because King got a very professional and experienced engineers, Shawn. 

They prepared very well; 

-The drying machine is assembled well in correct way; 
-Machines are placed in reasonable position;
-Electricity cables are ready to start all machines;
-Air presser is ready for the automatic block cutting machine.

Still want to say thank you for their preparation work! You guys are awesome!

The first day is very important because there is a lot of work to do.

Monday's work
-Inspect all machines well because there might be shaking damage on machines.
-Start all machines and teach workers to do every details that should be paid attention to.
-Communicate every details about production.

I never spoke so much English word and the embarrassed fact is that my English is not good enough...

Luckily they are so smart to understand what I am saying!

let's back to story.

This pine wood sawdust is what we going to use to produce pallet block. 

But in the beginning, the feeding speed of dryer is too fast and moisture can't reach what we demands(10%). This step is important for increasing the efficiency of production and quality of blocks. 

This is the oven made of steel plates.
But it seems that it doesn't work well in second day.
So we suggest you better don't do this.

King and Shawn also build another oven after we are back to China.

Now the oven works well.

At the same time, we are also preparing the glue water. 
King ordered glue powder from China with machines so we need to mix glue powder and water. 

Suggest buying glue locally like this.

When workers are busying mixing, our engineer starts the block machine molds heating setting to 145℃. 

After 20 minutes, 
-Sawdust have been dried 
-And MUF glue water is ready. 

Then we put the wood and the glue in the mixing machine as a ratio 85% wood and 15% glue. 

After 2 minutes, 
-Raw materials are fully mixed 
-And molds temperature have reached as set. (We start the heating 22 minutes ago)

Everything is ready. 
Then what are we waiting for? Let's do it.

Put raw materials into small storage bin.

Then the block machine starts running. 

In the beginning, there is no pressure for the sawdust in the molds. So after 8 minutes, the pressure in the molds came to be normal. 

Then blocks start being pressed. 

Ops! But there is a big problem! The long block starts broken one by one. Like the photo shows. 

Why? Why?

The reason is the moisture of sawdust. 

So a good dryer is very important. Our engineer is very experienced at this and then he adjust the speed of feeding sawdust and try to dry sawdust better.

And we recommend a professional moisture meter for sawdust like this. 

Then you will know the sawdust moisture very precise. 
The small one is not very precise because it is for metering the timbers or planks.

After drying the sawdust again and adjust the feeding speed to drying machine again, finally the moisture can reach what we demands(10%). 

And then we put them after mixing with glue, good quality blocks are finally produced like this.

Wooow!!

This is exactly what we want!!

Here is the video

And it is 5:30 p.m. so we are prepared to stop the machine and end today's work. 

And for better understanding, I put a video here to introduce the production line of press wood block for pallets. Please watch it here.

PS:
The long blocks can be cut into small blocks as required as the end of video shows. 

By the way, King pay for a nice hotel for us. It is so considerable after a long flying trip. Thank you very much again.
Photo comes,
