Diatomite Ultrafine Grinding Mill

09/09/2021 admin

Diatomite ultrafine grinding mill is a highly efficient ores powder grinder machine. It can grind diatomite into a fine powder (150-3000 mesh), and the fineness can be adjusted freely. In addition, it can also grind non-metallic minerals with Mohs hardness less than 6, such as calcium carbonate, mica, calcite, limestone, gypsum, etc. There are 2 main types of diatomite ultrafine grinding mill: HGM series ultrafine grinding mill and CLUM series ultrafine vertical mill.

diatomite uses

What is diatomite and its uses?

Diatomite, also known as diatomaceous earth, is the naturally occurring fossilized remains of diatoms. Its chemical composition is mainly SiO2, and its mineral composition is opal and its variants. The color of diatomaceous earth is white, off-white, gray and light gray-brown, etc. It has the properties of fine, loose, lightweight, porous, water absorption, and strong permeability.

It is commonly used in industry as insulation materials, filter materials, fillers, grinding materials, raw materials for water glass, decolorizing agents and diatomite filter aids, catalyst carriers, etc.

Diatomite crushing and grinding process

Diatomite powder can be obtained after being ground by a diatomite ultrafine grinding mill. After changing the particle size distribution and surface properties of diatomite through processing procedures such as crushing, grinding, sorting, calcination, airflow classification, and impurity removal, it can be applied to various industrial requirements such as paint and paint additives.

Stage 1: broken
The raw diatomite ore is crushed into small particles by the jaw crusher and then sent to the storage bin by elevator. Then through the vibrating feeder and the inclined feeding pipe, the diatomite particles are evenly sent to the bulk tray on the upper part of the turntable.

Stage 2: grinding
The diatomite particles are scattered to the periphery of the circle under the action of centrifugal force, and fall into

the raceway of the grinding ring to be impacted, rolled, and ground by the ring roller, and become diatomite powder after three-layer ring processing.

Stage 3: powder classification
The high-pressure fan sucks the outside air into the machine through suction and brings the pulverized diatomite powder into the powder concentrator. The rotating impeller in the classifier makes the coarse diatomite powder fall back and regrind.

Stage 4: collecting powder
The ultrafine diatomite powder that meets the requirements enters the cyclone powder collector with the airflow and is finally discharged from the discharge valve. The airflow with a small amount of fine dust is purified by the pulse dust collector and then discharged through the fan and muffler.
The powder conforming to the fineness enters the dust collector with the airflow for separation and collection. Then it is sent to the finished product silo and then packed by a powder tanker or an automatic baler.

Introduction to equipment configuration of diatomite powder production line:

The diatomite milling production line is an important equipment for milling diatomite. The milled diatomite can be used as fillers, filter aids, catalytic carriers.

>>Jaw crusher

The jaw crusher can effectively crush materials with a compressive strength of less than 320 MPa. It is an ideal equipment for coarse crushing of diatomite.

>>Grinding mill

The ultrafine industrial grinding mill is the main equipment for grinding diatomite. It can grind the material to 150-3000mesh, and the fineness can be adjusted freely.

>>Vibrating feeder

Through the electromagnetic vibrating feeder, the diatomite can be continuously, regularly, and quantitatively transported to the mill for milling, avoiding the clogging of the feed port and improving the production efficiency of the production line.

Modification of diatomite powder:

Diatomite ore generally contains more impurities, and there are more obvious physical and chemical structural defects, which greatly limit the adsorption capacity of diatomite. Therefore, it is necessary to modify diatomaceous earth to improve its adsorption capacity.

Through the powder modification process, some properties of diatomite can be improved more effectively, and diatomite resources can be fully utilized.

How to modify diatomite powder?

When grinding diatomite with SBM ultrafine grinding mill machine, a powder modifier can also be added directly to mix and grind with the material. The finished powder after grinding is the modified powder. But the quality of powder modified by powder surface coating machines will be better.

SBM Powder Surface Coating Machine can realize the surface modification of diatomite powder and improve the application performance of diatomite. If there is a need for powder modification, our designers will directly configure the equipment in the production line plan.

1. What is the use of diatomaceous earth in gardening?

Diatomaceous earth is used as a pest control agent. Because diatomaceous earth is composed of algae, it can be completely biodegraded and will not leave toxic waste, so it will not affect the health of animals or people.
Diatomaceous earth is used as fertilizer, and other fertilizers such as nitrogen, potassium and phosphorus contain many nutrients and minerals.
Diatomaceous earth prevents diseases, prevents diseases caused by humidity and temperature conditions.
Diatomaceous earth repels cats and dogs and prevents the presence of fleas.
Diatomaceous earth is used as a deodorant to remove bad odors in litter boxes and other places.

2. Is diatomaceous earth harmful to humans?

Diatomaceous earth is not harmful to the human body. Not only is it non-toxic and harmless, but it also has many advantages.
Diatomaceous earth is a fossilized diatomaceous earth deposit formed after the death of a single-celled plant called diatom after an accumulation period of about 10,000 to 20,000 years. Diatoms are one of the first protists to appear on the earth, living in seawater or lake water. It is this diatom that provides oxygen to the earth through photosynthesis and promotes the birth of humans, animals, and plants.

3. Which industrial grinding mill is the best for grinding diatomite?

Different types of grinding mills produced by different manufacturers have different working principles, and their grinding fineness and output are also different. Only choose the most suitable mill according to actual production needs, which is the best and the most cost-effective. Take the ultrafine mill developed and produced by SBM for example, the fineness can reach 150-3000 mesh, and can be adjusted freely. If you are in the early stage of your business and have a limited budget, you can choose the HGM series of ultrafine mills. The mill has stable operation, simple operation, convenient maintenance, long service life, and environmental protection. It is an industrial mill with high-cost performance. But if your downstream industries have higher requirements for powder, you can choose CLUM series vertical mills to produce a high-end powder. The vertical mill has a larger output, and the produced powder has a good shape and a higher fine powder content. Not only diatomite but also other non-metallic minerals. Our ultrafine mill can process non-metallic minerals with a Mohs hardness of less than 6. If you need a flour mill, you can contact us at any time. You only need to provide your processing raw materials and production needs, and you can get our production line formulation plan for free.
