Larox LPP-D15 was chosen for pumping Poly Glycol in the USA as reliability and accurate dosing was required in a cement making process.

Poly Glycol is added to the cement prior to the final grinding circuit. The customer was gravity feeding using a manual valve for controlling the grinding aid to the circuit and was not satisfied because they could not properly control the dosage. As already being familiar with Larox, the customer felt confident to choose a Larox pump for this application where reliability and good repeatability are needed. A VFD is used to control the pump flow to the circuit to adjust grinding aid dosage. The LPP-D pump has a high turndown ratio making it ideal for dosing in all process conditions. Finite control provides proper dosing to the system. The pump is operating with a high viscous media.

Grinding aids such as glycol, amines, and acetic acid help cement particles to flow efficiently which reduces grinding energy and results in increasing product through put.
