"when the Raymond mill is faulty" should not have the comma after "faulty." 5. “after-sales service” should consistently use either hyphen or no hyphen. If hyphenated, use "after-sales." 6. "Demand(multiple):" should have a space after "Demand" (i.e., "Demand (multiple):"). 7. "Materials (brochures, catalogs）" should replace the closing parenthesis with a standard one (i.e., "Materials (brochures, catalogs)"). 8.

The heading "Copyright © 2026" should be checked for the correct year if it's not intended to be in the future. 10. "Faceboo" is incomplete and likely meant to be "Facebook."
