FAQ

• Q: What dual functions can LM-Y vertical pre-grinding mill realize?

  A: It integrates sand making and coarse powder grinding in one unit. It can produce well-graded manufactured sand for mortar, and also make controllable coarse powder for cement clinker, slag and lime production, cutting separate equipment investment.

• Q: What feeding size and hourly capacity does LM-Y vertical pre-grinding mill support?

  A: The maximum feeding size is ≤20mm, and its capacity ranges from 6TPH to 330TPH. Multiple models match small lime plants, medium ceramic raw material workshops and large cement pre-grinding stations.

• Q: What raw materials are suitable for LM-Y vertical pre-grinding mill?

  A: It works for marble, feldspar, bentonite, dolomite, basalt, granite, cement clinker, slag, kaolin, lime and coal, widely applied in cement, power, metallurgy and dry-mix mortar industries.

• Q: Why is LM-Y vertical pre-grinding mill easy to maintain compared with ordinary vertical mills?

  A: It adopts hydraulic adjustment system, and grinding rollers can be flipped out of the machine entirely. Operators replace roller sleeves and liners rapidly without dismantling the whole mill, greatly shortening downtime.

• Q: How does LM-Y vertical pre-grinding mill guarantee good finished material quality?

  A: It adopts stable material bed grinding technology. For powder production, coarse/fine particle proportion can be precisely controlled; for sand making, finished aggregates own smooth particle shape and continuous gradation to meet mortar standards.
