Spodumene grinding mill is a milling machine used to process spodumene powder from 150 mesh to 800 mesh.

The spodumene grinding machine produced by CLIRIK is widely used for spodumene grinding powder of different fineness, and the machine is more environmentally friendly.

Compared with traditional stone mills, spodumene mills are relatively rare. Today, we will introduce the spodumene milling in Inner Mongolia that has gradually emerged in recent years. From the origin and use of spodumene to processing technology and equipment selection, we will give you a multi-faceted interpretation.

What is spodumene?

Spodumene is mainly produced in granite pegmatite veins and is the most important source of physical industrial minerals. It is a characteristic mineral in lithium-rich granite pegmatite. Unlike other minerals in the pyroxene group, spodumene is one A kind of pegmatite mineral, often associated with crystal, tourmaline, beryl, etc.

What are the uses of spodumene?

Spodumene belongs to the monoclinic crystal system, and the crystals are often columnar, granular or plate-shaped. The color is off-white, gray-green, purple or yellow, etc., and the hardness is 6.5-7. It is the main raw material for lithium chemical products and is widely used in the lithium chemical industry, glass, metallurgy, and ceramic industries. It enjoys the reputation of "industrial monosodium glutamate".

What are the main producing areas of spodumene?

The main sources of spodumene are Australia, Canada, Finland, etc. Among them, the reserves of the Greenbush granite pegmatite deposit in the western Persian region of Australia's spodumene are the largest in the world.

What is the processing technology of spodumene?

As the main source of lithium, spodumene is mainly processed into spodumene powder for ceramics, metallurgy, porcelain picking, special glass, chemical industry and other fields, and its current application in new energy vehicles has also received widespread attention. According to the requirements of these industries, spodumene is often made into 30-300 mesh spodumene powder as a raw material or medium. Therefore, the hectorite generally needs to be milled, and it needs to be milled with a mill.

The spodumene grinding process includes raw material crushing, conveying, and pulverizer grinding. Among them, the mill is the main process and equipment. There are many types of spodumene powder mills generally used to process 80-600 mesh. Specifically, there are coarse powder mills, which can process coarse powders of 30-80 mesh, and the new Raymond mill, which can process fine powders of 80-600 mesh. Both of these equipments are widely used in the spodumene grinding process. In addition to equipment selection, because the industry is still developing, many mill manufacturers do not have a deep understanding of the properties of spodumene, and it is particularly important to choose a professional manufacturer at this time.

Commonly used spodumene grinding mills

1. YGM Raymond grinding mill

Raymond grinding mill, also known as 3R/4R/5R roller grinding mill, is widely used in metallurgy, building materials, chemical industry, mining and other fields of mineral materials grinding processing. The output fineness between 613 micron ~440 micron (0.613mm - 0.044mm) . 

Raymond mill is mainly composed of main engine, analyzer, fan, cyclone separator, micro powder cyclone separator and air duct. Among them, the host machine consists of a frame, air inlet volute, shovel, grinding roller, grinding ring, cover shell and motor.
When working, the material that needs to be crushed is fed into the machine from the feed hopper on the side of the main machine housing, and relies on the grinding roller device suspended on the plum blossom frame of the main machine to revolve around the vertical axis. The roller swings outwards and is pressed tightly against the grinding ring, so that the shovel blade scoops up the material and sends it between the grinding roller and the grinding ring. The grinding roller rolls and crushes the material to achieve the purpose of crushing the material.

Air selection process: after grinding the material, the fan will blow the wind into the main machine housing, blowing the powder, separated by the analyzer placed above the grinding room, the fine and coarse materials fall into the grinding room for regrinding, fineness with the airflow into the swirling wind collector, after collection through the powder tube discharge, that is, the finished product. The air volume is returned to the fan by the return duct at the upper end of the big cyclone collector. The air path is circulating and flows under negative pressure. The increased air volume of the circulating air path is discharged through the exhaust pipe between the fan and the host machine, and enters the small cyclone collector for purification treatment.

2. HGM micro powder grinding mill

HGM micro powder grinding mill is also named three-ring medium speed micro powder mill.
It is a kind of fine powder and ultrafine powder processing equipment, mainly suitable for medium and low hardness ultrafine powder processing.

The complete configuration of mill includes hammer crusher, bucket elevator, storage bin, vibration feeder, micro mill host, frequency conversion classifier, double cyclone collector, pulse dust removal system, high pressure fan, air compressor, electrical control system.

When working, the main motor drives the spindle and the turntable to rotate through the reducer, and the roller pin on the edge of the turntable drives dozens of grinding rollers to roll in the raceway of the grinding ring.
The large material is broken into small particles by hammer crusher and then sent into the storage bin by elevator. After vibrating feeder and inclined feeding tube, the material is evenly sent to the bulk plate on the upper part of the rotary table.
Under the action of centrifugal force, the material is scattered to the periphery of the circle, and falls into the raceway of the grinding ring, which is impacted, rolled and ground by the ring roller. After three layers of ring processing, the powder is turned into powder. The high pressure fan draws the external air into the machine through suction, and brings the crushed material into the powder separator. The rotating impeller in the powder separator makes the coarse material fall back to regrinding, and the fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged from the discharge valve at the bottom of the product, while the airflow with a small amount of fine dust is discharged through the fan and muffler after purification by the pulse dust collector.

In short, it is very important to choose a manufacturer with rich experience in spodumene milling. You can submit the requirements for output, incoming and outgoing material size, finished product fineness and other requirements to the manufacturer, and they will provide professional design and selection, and then do more Comparative analysis, combined with on-site inspections, make a relatively scientific choice.
