LM Vertical Grinding Mills For Limestone

LM Series limestone slag coal vertical grinding mill is a progressive grinding machine, which integrated with drying, milling, grading and transporting. Vertical mill play an important role in the cement industry . and vertical roller mill have been widely accepted by the combined grinding and drying of the wet raw materials because of their excellent drying capacity and low energy consumption. Although a number of cement plants are still using ball mills, many have installed pre-grinders like roller press to improve the energy efficiency of energy use.

Processing Of Limestone

In the process of production and processing of limestone, it mainly uses the following equipment:milling machine (Raymond mill or high pressure grinding), jaw crusher, hammer crusher, impact crusher, sand making machine.LM series milling machine is the vertical mill products with independent intellectual property rights, which is based on the advanced grinding technology of my company in the technical advantages of vertical mill products increasingly prominent situation. We actively learn from foreign successful experience, and constantly innovate through R & D team upgrade.

Application Of Limestone

Limestone has numerous uses: as a building material, as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, and as a chemical feedstock.

The main constituent of limestone is calcium carbonate (CaCO3). Lime and limestone is mainly used as building material. It is also an important raw material for many industrial. Limestone can be directly processed into stone and lime. Lime can be categorized into ordinary lime and hydrated lime. The main component of the ordinary lime is CaO. It general is massive, pure white and containing impurities as a light gray or yellow. Lime moisture absorption or added water will become hydrated lime, slaked lime or slaked lime; it is the main component of Ca(OH)2. The hydrated lime is made into lime mortar, used as coating materials and tile adhesive. Some places will also call: limestone, calcite, marble, chalk, and aragonite.

Introduction Of Limestone

Limestone is very common in architecture, especially in Europe and North America. Many landmarks across the world, including the Great Pyramid and its associated complex in Giza, Egypt, are made of limestone. So many buildings in Kingston, Ontario, Canada were constructed from it that it is nicknamed the 'Limestone City'. On the island of Malta, a variety of limestone called Globigerina limestone was, for a long time, the only building material available, and is still very frequently used on all types of buildings and sculptures. Limestone is readily available and relatively easy to cut into blocks or more elaborate carving. It is also long-lasting and stands up well to exposure. However, it is a very heavy material, making it impractical for tall buildings, and relatively expensive as a building material.

Limestone was most popular in the late 19th and early 20th centuries. Train stations, banks and other structures from that era are normally made of limestone. It is used as a facade on some skyscrapers, but only in thin plates for covering, rather than solid blocks. In the United States, Indiana, most notably the Bloomington area, has long been a source of high quality quarried limestone, called Indiana limestone. Many famous buildings in London are built from Portland limestone.
