The Alunite Crusher can be applied in many crushing process . For Alunite Crushing Plant Line, Alunite Crusher or Alunite grinding machine for mining Alunite is very important when choosing Alunite Crusher Manufacturer. Here is knowledge about Alunite mining, Alunite crusher, Alunite grinding machine, calcined Alunite grinding, etc. Welcome to choose SBM for mining Alunite Project.


  • Potassium Aluminum Sulfate Hydroxide
  • KAl3(SO4)2(OH)6
  • Alunite is the sodium substitute for potassium, and when it is high in sodium, it is called natroalunite

Crushed Alunite Application

It is a good source of alum. Sometimes, it is also used to recover potassium and aluminum. Commercially it is used as alloys, tools, equipment.

ALUNITE IS also known as alumstone. This mineral was first observed in the 15th century at Tolfa, a place near Rome. Here, it was mined to manufacture alum, KAl(SO4)2 - 12H2O.

Alunite Crushing Plant & Equipment

  • Alunite is formed from the action of sulfuric acids upon potassium rich feldspars in the process called as "alunitization." The sulfuric acids accompany hydrothermal solutions. It is generally rich in certain ore metals. These solutions result in large bodies of alunite.
  • Sometimes, alunite is mistaken for massive rock forming dolomite or limestone (calcite). An acid test proves the identification. Alunite does not bubble even when powdered.
  • The Crushing Process of Alunite is quite similar to normal stone crushing processing.
  • Firstly, we choose the usable materials and transmit them with the vibrating feeder. Then vibrating feeder pours them into primary Alunite crusher. Then products of primary Alunite crusher get crushed by secondary Alunite crusher.
  • Secondary Alunite crusher crushes stones into smaller size and usually they can get used. But more often the products of secondary Alunite crusher get screened by vibrating screen and whose can fit the requirement will leave this process and become the final product and the others will go back to secondary Alunite crusher or even primary crusher to get crushed.
  • Finally, Alunite all become the right products . Tertiary Alunite crusher is usually used in special crushing process. Tertiary Alunite crusher will process stones into much smaller size than secondary crusher.
  • We usually choose mobile Alunite crusher or portable Alunite crusher is this process. Because it is really convenient to use mobile Alunite crusher or portable Alunite crusher in this process.

Occurrences of Alunite

  • Alunite occurs as a vein and replacement mass in trachyte, rhyolite, and similar potassium rich volcanic rocks. It is also formed at volcanic fumaroles. The white, fine granular mass of alunite closely resemble the fine granular limestone, dolomite, anhydrite, and magnesite in appearance. The compact kinds, which come from Hungary, due to its hardness and toughness, are used for millstones.
  • Presently, alunite is found at Tolfa in Italy. In the U.S., it is found in the San Juan district of Colorado; Goldfield, Nevada; Marysvale, Utah; and Red Mountain in Patagonia, Arizona. The occurrence in Arizona lies above a canyon named Alum Gulch. It is mined as an ore of both, potassium as well as aluminium at Marysvale.

Alunite Crushing Process

alunite crushing process

Alunite crushing process and the process is mainly divided into the following aspects:

Crushing Process

  • ① a broken process. A broken process is generally used to provide the right from the feed mill, often constitute a system with self-mill. The process is simple, less equipment, plant and small footprint.
  • ② two crushing process. The mostly small-scale plant using the process.
  • ③ three sections broken process. The basic form of the process open and three sections of three sections of a closed two.
  • ④ work with broken washing process. When the feeding of the mud (-3mm) of more than 5% to 10% and water content greater than 5% to 8%, should increase in the crushing process Alunite washing operations.

Grinding and Classification Process Procedures

  • In terms of dressing, using a grinding or two can put the economy grinding to a mineral Alunite to any size needed. Two or more grinding, usually elected by the other requirements of the decision stage.
  • Period and compared to two processes, a grinding process of the main advantages are: less equipment, low investment, simple operation, do not stop because of a grinding segment to another segment of the work of grinding, less downtime losses. But the mill to the Alunite particle size range, a reasonable ball hard, not easy to get the final product of smaller, low grinding efficiency.
  • When asked the maximum particle size of the final product of 0.2 ~ 0.15mm (or 60% to 79% -200 mesh), generally used a grinding process. Small factories, in order to simplify the process and device configuration, when the grinding fineness required 80% -200 mesh, we also used a grinding process. Two outstanding advantages of grinding can be smaller products, in different sections coarse grinding and fine grinding, especially for stage process.
  • In large and medium-sized factories, as required grinding fineness is less than 0.15mm (ie 80% -200 mesh), using two grinding more economical, and uniform particle size composition, was less than smashing. Under the first paragraph of the mill is connected with the classification of different ways, the two grinding process can be divided into three types: the first open; second paragraph of the entire house; first local house, and the second is always closed circuit grinding work process.

Grinding Process

  • Since the grinding process is classified to dry and wet. Concentrator to use more wet. Since the mill in order to solve the difficult problem of wear particles to improve grinding efficiency, adding a small amount from the ball mill, then known as the semi from the mill.
  • Since the constant grinding and crushing, milling, grinding gravel crushing equipment, joint work, based on their association composed of a variety of ways to process.
