High pressure suspension mill grinding chamber shape and liner abrasion relationship:

For powder grinding mill machine, different powder grinding chamber determined different liner abrasion condition for the same kind powder grinding mill.

High pressure suspension grinding mill grinding chamber abrasion has the following analysis:
a. During high pressure roller mill start working process, transport to the machine parallel zone will stack too much raw material at the feed opening, later will decrease sharply. Thus, parallel area suffering strong abrasion and high pressure suspension mill working several day, parallel area will be change gradually.
b. With liner board abrasion and powder grinding chamber layout change degree, along the powder grinding chamber height grinded raw material with uniform distribution. In liner limit abrasion range all the machine exist grinding chamber layout size change condition, especially later period hasn't parallel area, the whole grinding chamber completel lost organic layout. Besides, feed opening size about decrease 1.4-1.7 times, feed opening processed the most raw material. As without parallel area make output products with bad quality, the production capacity will be decrease.

In a word, as high pressure suspension mill uneven liner abrasion, powder grinding chamber will lost organic shape, lead to liner with lower using life and decrease technical economical standards.
