What Is The Purpose Of Secondary Crushing In Production Of Lime
Secondary crushing is accomplished by smaller crushers that work at higher speeds, producing pebbles which are then ground and pulverized. 3 The next phase, wet grinding, washes away impurities. It is used to make the fine grade of limestone necessary to make chalk suitable for writing purposes.

Acid-Base Titrations: Standardization of NaOH and Antacid
In this experiment, the reagents combined are an acid, HCl (aq) and a base, NaOH (aq) where the acid is the analyte and the base is the titrant. The reaction between the two is as follows: HCl (aq) + NaOH (aq) → H2O (l) + Cl –(aq) + Na +(aq) In this case, Sodium and Chloride act as spectator ions and form into salts in a neutralization

Mineral processing
Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding. The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant.

Crushing Vs Grinding
Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling. Additionally, some chemical reagents can be used to minimize the energy consumption of grinding, because grinding energy is minimum at pH of the point of zero electrical charges of the
