Description

Limestone vertical mill integrates fine crushing, drying, grinding, powder selection, and transportation. It has the characteristics of small footprint, simple process flow, high grinding efficiency, low energy consumption, low noise, large drying capacity, easy adjustment of product fineness, no dust pollution, convenient maintenance, and reliable operation. Especially in large-scale grinding processes, it fully meets customer needs, and its main technical and economic indicators reach international advanced levels. Widely used in large-scale material grinding and ultrafine grinding processing in industries such as metallurgy, electricity, cement, chemical industry, ceramics, non-metallic minerals, power plant desulfurization, water slag, slag, furnace slag, coal, cement clinker, glass, quartz, limestone, etc.

Compared with ball mills, limestone vertical mills have lower operating costs in the grinding system. The main performance characteristics are:
(1) High grinding efficiency, can grind limestone or heavy calcium stone, using grinding rollers and material beds to crush and grind materials, low energy consumption, system power consumption reduced by 40-50% compared to ball milling system, and more significant energy-saving effect.
(2) Can process products with a mesh size of 300 to 2000, and the product quality is self controlled.
(3) Equipped with an external circulation device, it can further reduce power consumption.
(4) Taiwan's hourly production is high, exceeding 20 tons per hour.

Working principle:

The electric motor drives the grinding disc to rotate through the reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the wind ring at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and the qualified fine powder is discharged with the airflow, Collecting in the powder collection device is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

Application Area
The HVM vertical grinding machine, with its scientific and reasonable design and unique structural advantages, is widely suitable for grinding various types of materials in various industries. The materials ground range from high humidity to dry, from exceptionally difficult to easy to grind, and the product fineness ranges from coarse to fine. The processed powder types are diverse, involving numerous industries:
① Moisture content of grinding materials: From materials with a moisture content of 20-30% (such as calcium carbide slag, brown coal, chalk soil, etc.) to materials with a moisture content less than 1% (cement clinker, etc.), the materials have strong adaptability;
② The grindability of grinding materials: from exceptionally difficult to grind (such as quartz sand, steel slag, slag, pyroxene, iron ore, etc.) to easily ground (such as gypsum, calcite, etc.);
③ Grinding product fineness: From 2-5mm (such as new wall material industry brick raw materials, construction industry sand grinding shale, etc.) to 15um with a pass rate of 97% (such as papermaking, chemical industry grinding heavy calcium, etc.), the control of product fineness is simple and easy;
The industries where HVM vertical grinding machines are applied include building materials, electricity, steel, energy, heat, chemical, coal chemical, non-ferrous metallurgy, lime kilns, mineral processing, and other industries.
The HVM vertical mill can process materials such as ferrite, slag, slag, cement, diamond, iron ore, chromium ore, manganese ore, gold ore, copper ore, aluminum ore, lead zinc ore, tantalum niobium ore, polymetallic ore, nickel ore, bauxite, silicon carbide, titanium dioxide, talc, bentonite, calcite, kaolin, graphite, mica, wollastonite, feldspar, dolomite, pyrophyllite, quartz sand, fluorite, limestone, organic silicon, lithium ash, shale, volcanic ash, coal, etc.
