What is a Grinding Aid? (with picture) - wiseGEEK

A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity. These benefits of cement grinding aid use ...

Sika Solutions for Cement Production

grinding aid, the production rate increases and the separator rejects decrease. Beyond this maximum, further increased dosage results in shorter time for the cement to pass through the mill. If the mill retention time is reduced too much, the cement is insufficiently ground which leads to increased separator rejects and hence a reduced production rate. Traditional grinding aids are based on ...

Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to ob tain the product, but it is usually more expensive, requires more energy and reduces capacity. The economic alternative is to use a grinding aid. Grinding aid or grinding additives refer to substa nces which when mixed into the mill contents cause an ...
