IELTS Writing Task 1: process diagrams

The following paragraph describes the process of making cement.

At the first stage in the cement production process, limestone and clay are crushed to form a powder. This powder is then mixed and passed through a rotating heater. The resulting mixture is ground, and finally the end product, cement, is packed into large bags.

There are 2 things that make process descriptions special:

1. Phrases that order the process and link the steps (underlined)
2. Passive verbs (highlighted)

(See Cambridge IELTS book 8 for the full question)

Hello simon
I would be pleased if you answer my Q.
I am following your way to answer TASK2 writing ( introduction - 2 main paragraph and conclusion ) but my tutor told me that I miss my opinion when Q ask for even when I stated in introduction and conclusion, he said that I have to add opinion to each idea I write and each paragraph.
honestly, I have been confused because I used to your way and it is hard to change it.
do you agree with him , or you advice me to keep on yo way?
thank you
John

Please help me, I'm struggling to talk about this

Dear Simon,

Can you please write the second paragraph on the concrete production as well? I tried to write the full 150 word essay but it seemed that I was short of words (I managed to write only 100 words). Do we need to compare the two processes here?

Thanks a lot.

Li.

Simon, I've had the same problem of Li. I've written the essay but it was very short. I don't have enough criativity to improve this specific question. What is your sugestion?
Thank you!!
