Ore Grinding Mill

Introduction

Ore vertical mill is also choice for nonflammable and non-explosive minerals of which Mohs hardness is less than 9.3, moisture content is less than 6%, for example: quartz, feldspar, calcite, talcum, barite, fluorite, rare earth, marble, ceramic, aluminous bauxite, manganese ore, iron ore, copper ore, phosphorus rock, red ferric oxide, zircon, slag, granulating slag, cement clinker, active carbon, dolomite, granite, garnet, yellow ferric oxide, fertilizer, multiplex fertilizer, fly ash, soft coal, coking coal, lignite, magnesite, chromium oxide green, gold ore, red clay, clay, kaolin, coal tar creosote, coal slack, porcelain clay, cyanite, fluorspar, bentonite clay, medical stone, rhyolite, greenstone pyrophillite, shale, basalt, gypsum, graphite, etc.

The fineness from the finished product could be adjusted from 100 mesh to 325 mesh according to specific requirements of clients.

Features

1. Composite separator improves the efficiency of the powder.

2. With the function of automatic lifting and falling , can realize no-load starting.

3. Welded type arc plate is used for sealing, it features simple structure, reliable performance, well-sealed structure.

4. By means of the roller swing-out device, the grinding rollers can be turned out of the mill, which is in favor of maintenance.

5. The limit mechanism avoids the fiction and crash of metals between grinding roller and grinding plate, increasing the rotating stability and security.

6. Operating pressure of hydraulic system is low, can reduce the leakage failure and the mill vibration , is good for operation and management.

7. The centralized circulating oil lubrication is applied to the grinding roller bearings, which ensures the bearing operate at constant temperature and with pure oil, so that longer service life is achieved.
