Summary: This article introduces multi‑sector applications of limestone powder and processing flows. It compares MTW6X intelligent European mill and LM-Y Vertical Pre-grinding Roller Mill and provides key selection advice.
Limestone is high‑abundance non‑metallic mineral dominated by calcium carbonate. Ground limestone powder is extensively used in power‑plant flue‑gas desulfurization, construction mortar, feed additives, rubber‑plastic fillers and chemical raw materials. Required fineness varies greatly across downstream industries: 200‑325 mesh for desulfurization and above 400 mesh for fillers. Though limestone has moderate hardness, feed particle size, impurity content and moisture will greatly influence plant capacity and component wear.

Limestone grinding process includes primary crushing, elevating & stockpiling, metering feeding, pulverizing, classification and finished‑product collection.
For medium‑and‑small‑size plants focusing on desulfurization and building‑material fillers, MTW6X Intelligent European Grinding Mill is a good choice. It inherits proven European‑mill structures and adds intelligent remote control. Thin‑oil lubrication lowers failure rate, with adjustable output fineness 80‑400 mesh. Operators can run it after simple training for hourly output from several tons to dozens of tons.
For composite projects requiring both manufactured sand and mineral powder, choose LM-Y Vertical Pre-grinding Roller Mill. One machine produces both aggregate sand and limestone powder, greatly reducing total investment and suiting building‑material industrial parks. The whole line adopts dust‑removal system with negative‑pressure operation to meet environmental standards.
Many clients only focus on equipment price while ignoring raw‑material conditions, site constraints and long‑term maintenance cost. If you have a limestone‑grinding project plan, please leave a message with feed size, target capacity and required mesh. Submit your demand via business consultation and our engineers will deliver customized configuration and budget estimate.
FAQ
Q1: What mesh is suitable for power‑plant desulfurization limestone powder?
A: 250‑325 mesh is mainstream. Finer powder improves desulfurization efficiency yet increases power consumption.
Q2: Can one set of equipment produce both sand and limestone powder?
A: Yes. LM-Y Vertical Pre-grinding Roller Mill realizes dual‑purpose sand‑making and powder‑grinding.
Q3: What risk does high‑moisture limestone bring?
A: Excessive moisture causes material blocking and mill‑plate sticking. Drying unit or mill with built‑in drying function shall be adopted.
