For the limestone crushing plant, there are jaw crusher, cone crusher, impact crusher and hammer crusher for your choice.
1. Limestone jaw crusher is widely used as primary crusher in primary limestone crushing process. the working principle is plate pressing, so the percentage of stones with flaky shape, internal cracks is high. Primary crushing of limestone requires high crushing ratio to reduce the raw limestone down to the required grain size.
2. Limestone cone crusher is often used as secondary crusher. The working principle also is plate pressing, so the percentage of stones with flaky shape, internal cracks is high. The limestone cone crusher is applicable for various coarse, medium, fine materials, such as granite, limestone, concrete, basalt, bluestone etc, whose grain size not exceeding 500mm and compression strength not higher than 360Mpa.
3. Limestone Impact crusher is also common crushing machine used in limestone quarries, and it is common used as a territory crusher. It has the functions of crushing and shaping, and can make very good cubic shape. the stone materials are mainly used for highway, water conservancy, airport, civil construction etc. The market prices of stones made by impact crusher is higher than that by fineness jaw crusher or cone crusher; the quick wear parts cost of impact crusher is also high for high hardness stones.

Information about Limestone
Limestone is a very common sedimentary rock composed largely of the minerals calcite and/or aragonite, which are different crystal forms of calcium carbonate (CaCO3). Sometimes it is almost pure calcite, but most of limestone are filled with lots of other minerals and sand and they are called dirty limestone.
Limestone makes up about 10% of the total volume of all sedimentary rocks. In its broadest interpretation the term includes any calcareous material such as marble, chalk, travertine, tufa, limeshell, coral and marl each possessing different and distinct physical properties. The crystalline equivalents of limestone having the same chemical composition are calcite and aragonite. The rock containing more than 95% of calcium carbonate is termed high-calcium limestone. Recrystallised limestone takes good polish and is used as decorative and building stone. It is then called 'marble'.
Limestone is widely quarried for roadbeds, building and landscape construction, and cement manufacture. Limestone is the primary source of lime stone for cements or concrete. Cement is considered one of the most important construction materials ever invented by man. Limestone can be crushed and used as road ballast. Significant quantities of limestone are quarried around the world for these purposes.
Uses of Limestone Include:
• The manufacture of quicklime (calcium oxide) and slaked lime (calcium hydroxide);
• Cement and mortar;
• Pulverized limestone is used as a soil conditioner to neutralize acidic soil conditions;
• Crushed for use as aggregate—the solid base for many roads;
• Geological formations of limestone are among the best petroleum reservoirs;
• As a reagent in flue gas desulfurization (sulfur dioxide air pollution control);
• Glass making, in some circumstances;
• Added to paper, plastics, paint, tiles, and other materials as both white pigment and a cheap filler.
• Toothpaste
• Suppression of methane explosions in underground coal mines
• Added to bread and cereals as a source of calcium
• Calcium supplement for poultry (when ground up)
• Remineralizing and increasing the alkalinity of purified water to prevent pipe corrosion and to return essential nutrients
• Used in blast furnaces to extract iron from its ore
• Medicines
• Cosmetics
• Art (sculptures)
