About Vermiculite

Vermiculite is a natural, inorganic, non-toxic mineral that will expand under the action of high temperatures. It is a relatively rare mineral, belonging to silicate, usually in the form of lumps, flakes, and granules. Its crystal structure is monoclinic, which

looks like mica from its appearance, and is the product of weathering and alteration of natural minerals such as biotite. Hardness 1~1.5. The relative density is 2.4~2.7.

Vermiculite is generally brown, yellow, dark green, with an oil-like luster, and turns gray after heating. Vermiculite can be divided into vermiculite flakes and expanded vermiculite in stages.

Vermiculite is produced when certain granite is hydrated. It is generally produced at the same time as asbestos. Because vermiculite has the ability of ion exchange, it has a great effect on the nutrition of the soil.

Vermiculite has a wide range of uses. It can be used as building materials, adsorbents, fireproof insulating materials, mechanical lubricants, soil conditioners, and so on.

Vermiculite Processing Technology

The vermiculite powder is roasted, sieved, and ground into powder form from raw vermiculite ore at high temperatures.

Product specifications: 8-12mm, 4-8mm, 2-4mm, 1-2mm, 0.3-1mm, 40-60 mesh, 60-80 mesh, 80-100 mesh, 100 mesh, 150 mesh, 200 mesh, 325 mesh, etc. Specifications can be produced according to requirements.

20-40 mesh: Mainly used in automobiles, airplanes, cold storage, wall panel water cooling towers, steel annealing, fire extinguishers, filters, etc.

40-120 mesh: Mainly used for linoleum, roof slabs, dielectric gates, etc.

120-270 mesh: Mainly used for fireproof cardstock for wallpaper printing, outdoor advertising, paint, and photographic cork boards.

325 mesh and above: Mainly used for golden yellow and bronze, ink cartridges, fireproof fillers.

Vermiculite Powder Production Line Process

Crushing stage:

The raw material of vermiculite is first crushed by a jaw crusher, and the fineness is generally maintained within 15mm-50mm, which helps to reduce the load of the mill and improve the grinding effect.

The jaw crusher produced by our company has a more convenient operation, larger crushing ratio, and better quality of vermiculite particles after crushing. And the price is quite affordable, 3%-5% cheaper than other devices of the same type.

Grinding stage:

After crushing, the vermiculite particles are evenly sent to the silo through the bucket elevator, and then the material is evenly sent to the industrial mill to be fully ground by the electromagnetic vibrating feeder. According to different grinding requirements, different grinding equipment can be selected.

For vermiculite powder of 80-325 mesh, you can use a high-pressure mill; for vermiculite powder of 150-2500 mesh, you can use an HGM ultrafine grinding mill. If you have higher requirements for powder quality, you can use a CLUM vertical roller mill.

The fineness of the above industrial grinding mills can be adjusted freely within the interval, which can better adapt to the fineness requirements of vermiculite powder in different industrial fields. In addition, the explosion-proof measures for the vermiculite industrial milling equipment are in place, which can avoid dust explosion accidents caused by improper operation and create a safe and good on-site environment.

Powder selection stage:

After grinding, the vermiculite material needs to be classified by the analyzer, and the unqualified fine powder will be returned to the mill to continue grinding until it meets the fineness requirements.

Powder collection stage:

After powder selection, the fine vermiculite powder that meets the fineness requirements is separated and collected in the dust collector through the pipeline. It is then sent to the finished product silo for unified packaging.
