acid demand phchromite sand testing

pH test but are soluble in slightly acidic conditions and can then participate in acidbase reactions • Consistent and low acid demand values are preferred to ensure predictable and consistent curing of the sand in typical organic foundry binder systems • High acid demand values can interfere with both acidic and basic catalyzed systems and lead to slow or overly rapid curing times and low strengths... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.

Hi,may I help you with products, price, etc?
