After calcination, bauxite becomes core raw material for refractory bricks and castables. Refractory production requires bauxite aggregate of different particle sizes plus fine powder. Purchasing independent sand maker and grinding mill leads to high investment and large land occupation, which brings pressure on medium & small refractory factories. SBM LM-Y Vertical Pre-grinding Roller Mill solves this pain point: one single machine produces coarse aggregate and ultrafine powder synchronously.
LM-Y Vertical Pre-grinding Roller Mill adopts enlarged grinding chamber suitable for high-hardness bauxite. Feeding size reaches 60 mm, hourly capacity ranges from 30 tons to 900 tons to fit refractory factories of different scales. Built-in dual classification system produces refractory aggregate sand via one channel and 20–400 mesh bauxite fine powder via another channel. No two main machines are needed, greatly lowering equipment purchase and workshop land cost.
The machine integrates drying, grinding, classification and conveying. Wet raw bauxite can be fed directly without pre-drying. Negative-pressure dust removal guarantees emission standards. Centralized automatic control enables single operator to manage the whole production line. Multiple refractory industrial parks equip LM-Y Vertical Pre-grinding Roller Mill. Synchronous supply of graded bauxite raw materials doubles production efficiency.
A complete integrated bauxite line includes jaw crusher, bucket elevator, silo, LM-Y main mill, dual-path finished silo, dust removal and packing equipment. SBM engineers adjust classification system according to particle size requirements of refractory materials and design integrated factory layout free of charge. We provide field installation and commissioning of full equipment.
If your refractory plant needs simultaneous bauxite aggregate and fine powder output and want to cut equipment investment, send raw material hardness and target capacity via online consultation. Our engineers design exclusive integrated sand & powder process scheme.
Summary: LM-Y Vertical Pre-grinding Roller Mill realizes integrated bauxite sand making and grinding. One machine outputs both aggregate and fine powder up to 900 t/h, the preferred integrated processing equipment for refractory material factories.
