Summary: This article covers quicklime powder applications and processing workflows. It compares LM vertical mill and MTW European mill, and gives practical selection tips for quicklime powder projects.
Quicklime, also known as calcium oxide, features strong alkalinity and high activity. It is widely adopted in metallurgical desulfurization, sewage treatment, building materials and chemical fillers. Blocky quicklime cannot be directly applied in production and shall be crushed, ground and classified into powder. 200‑325 mesh is the mainstream fineness for industrial products. Quicklime absorbs moisture and is easy to hydrate, so grinding lines must integrate drying, pulverizing and dust suppression. Improper equipment selection will cause caking, coarse overflow and excessive dust emission.
Standard quicklime grinding workflow: raw material crushing → elevating & storage → quantitative feeding → grinding → air classification → finished‑product collection & storage.
For medium‑and‑small‑size processing plants, **MTW European Grinding Mill** is recommended. It adopts thin‑oil lubrication for stable operation, negative‑pressure closed structure for low dust, and adjustable fineness ranging from 80‑400 mesh. With easy maintenance, it fits projects with annual output from tens of thousands to 200‑300 thousand tons.

For large‑scale million‑ton‑level quicklime projects, **LM Vertical Roller Mill** is preferred. It integrates crushing, drying, grinding, classification and conveying, occupying small footprint and allowing semi‑outdoor layout. It delivers large single‑unit capacity and cuts energy consumption by around 40 % compared with conventional grinding equipment for continuous high‑volume production.

SBM production lines can be equipped with hot‑air drying modules to handle high‑moisture raw materials, together with pulse dust collectors for environmental compliance. Project configuration cannot be simply copied from other cases, since feed size, capacity requirement and site conditions vary for each client.

FAQ
Q: What mesh size is commonly required for quicklime powder?
A: 200‑325 mesh for general industrial use. 250‑325 mesh for desulfurization and 200 mesh for metallurgical flux.
Q: Which is better for quicklime: vertical mill or European‑style mill?
A: LM vertical mill for million‑ton large‑capacity projects; MTW European mill for medium‑small projects with lower investment threshold.
Q: Is drying necessary for quicklime grinding lines?
A: Drying is required for high‑moisture feedstock to prevent hydration‑induced caking and guarantee powder quality.
