Barite is a barium-containing mineral that appears in white or light yellow color. It is widely used in the chemical industry, papermaking, textile, coating, chemistry, and other major fields. After deep processing, it becomes ultra-fine barite powder. The uses and production process are as follows. Will be introduced.
Ultrafine barite powder production process and processing equipment
Barite has moderate hardness, with a Mohs hardness of 3-3.5. Grinding is one of the only ways to realize its comprehensive value. A series of crushing and grinding equipment is used to process the large pieces of barite mined into powder. status, application in different fields can reap significant value. What is the specific barite grinding production line equipment? What is its process flow? Next, we will understand one by one.
Ultrafine barite powder production process flow
The first stage: large pieces of barite are transported to the raw material warehouse by vehicles, and then the materials are sent to the jaw crusher by forklifts/manuals to process until the fineness of the materials can enter the grinding equipment, and the discharge port gasket is adjusted through the discharge port gasket. material.
Second stage: The crushed barite is sent to the silo by a bucket elevator, and then uniformly and quantitatively sent to the barite ultrafine crusher via a belt feeder for grinding, from lumps to finished powder.
Three stages: The ground ultra-fine barite powder is classified by the classifier. Unqualified powder is classified by the classifier and returned to the barite ultra-fine crusher for secondary crushing.
Four stages: Powder that meets the fineness enters the collector through the pipe with the air flow for separation and collection. The collected finished ultrafine barite powder is sent to the finished product silo or finished product tank through the discharge port through the conveyor device, and then is uniformly loaded with powder. Tank truck or automatic packaging machine for packaging.
Five stages: If there are finer crushing requirements, the barite ultra-fine crushing can be continued with an airflow mill to crush the barite to D50: 2μm or so. Give barite a higher added value.
Uses of ultrafine barite powder
80%-90% ultrafine barite powder is used as a mud weighting agent in oil drilling. In addition, barite is difficult to tolerate water and acid, non-toxic, non-magnetic, and can absorb X-rays and gamma rays. Has the following uses:
- Oil drilling: circulating mud weighting agent in rotary drilling of oil and gas wells. Cool drill bits, lubricate drill pipes, seal hole walls, control oil and gas pressure, prevent oil wells from blowing out, etc.
- Chemical industry: catalysts, coagulants for synthetic rubber, fluorescent powder, grease additives, reagents, textiles, fire protection, various fireworks, plastics, pesticides, welding flux, etc.
- Glass: Increase the optical stability, gloss and strength of glass.
- Rubber: plastic paint, filler, gloss enhancer, weighting agent.
- Construction: Concrete aggregates, paving materials, pipes buried in heavy swamp areas, replacing lead sheets for shielding nuclear facilities, atomic energy plants, X-ray laboratories, etc., extending the life of the road.
