The main component of limestone is calcium carbonate (CaCO3). Limestone can be directly processed into stone and burned into quicklime. Quicklime CaO becomes slaked lime by absorbing moisture or adding water. The main component of slaked lime is Ca(OH)2, which can be called calcium hydroxide. The slaked lime is prepared into lime slurry, lime paste, etc., used as coating material and brick adhesive . Lime and limestone are a large number of raw materials used in construction materials and industries. If the powder is further processed into limestone powder, it can be widely used in building materials, chemical industry, metallurgy, medicine, papermaking, food and other fields.



The limestone milling system is mainly composed of limestone crushers and limestone mills. The following are some common limestone mills and crushers.

 

Limestone Crushers

1. Jaw crusher

It was developed and manufactured by the United States in 1858. It is suitable for crushing materials with medium hardness and above. Compared with other crushers, the jaw crusher has simple structure, convenient maintenance and low price. Therefore, the jaw crusher is the best-selling crusher on the market.

2. Cone crusher

It came out in 1927 and was officially used in industry. The crushing ratio is large, the efficiency is low, the energy consumption is low, and the product size is uniform. It is suitable for medium crushing and fine crushing of various ores and rocks. Moreover, it has light abrasion and low dust during working.

3. Impact crusher

Impact crusher also known as sand making machine): Impact crusher is abbreviated as impact crusher. It is a product of the 1990s and uses the working principle of rock-on-rock.

Advantages: The particle size of the product is small and delicate, and the material with different hardness is used; the impact crusher consumes low energy in the production process, high output, simple structure and convenient maintenance.
 

4. Impact crusher

The impact crusher is abbreviated as counterattack breaker, which was made in 1924.

Advantages: The crushing ratio is large, and the crushed materials are of good shape, mostly cubic particles, and the discharge size can be adjusted. It is a high-yield, low-consumption, and structured equipment.
 

5. Hammer crusher

Hammer crusher is abbreviated as hammer crusher.

Advantages: simple structure, easy operation, light equipment and convenient maintenance.

 

Limestone mills

1. Raymond mill

It is the Raymond mill and Raymond machine that people often say. Raymond mill can be said to have a very long history. It is the earliest model in the milling equipment. So far it has a very high share of the production line. With the development, the Raymond mill has also undergone several updates. Compared with the old equipment, the modified Raymond mill has a higher screening rate of 99% and adopts a centralized control system. The improvement of the traditional artificial Raymond mill has become a very highly automated equipment.
 

2. Vertical mill

Vertical mills, also called vertical mills and vertical mills, are a new type of energy-saving and consumption-reducing production line equipment. It has advantages over other similar production line equipment in terms of energy consumption and environmental protection, and has a single production output and fine powder production. In comparison, the efficiency has been significantly improved, which is the energy-saving and consumption-reducing production line equipment advocated by our country.
 

3. High pressure suspension roller mill

It is also called high-pressure mill and suspended roller mill. This equipment can grind materials with higher hardness, and it can grind materials below 9.3 Mohs level. The fineness of the finished product of this model can reach 1000 after modification. The mesh size is around, and the fineness can be adjusted freely between 0.613mm to 0.33mm, which is more adaptable.
 

4. European version mill

This equipment is a relatively large-scale equipment. Because its design principle is based on the advanced technology of European mills, it is called European mill. After improvement, this equipment has less energy loss and higher efficiency. Belongs to large equipment.



In the first stage of coarse crushing, large pieces of limestone are uniformly fed by the vibrating feeder through the silo, and then transported to the jaw crusher for coarse crushing. After the coarse crushed materials are screened by the vibrating screen, they are transported to the counterattack by the belt conveyor Type crusher. After the coarse materials transported to the impact crusher are crushed by the impact crusher, the circular vibrating screen is used to screen the crushed materials through the impact crusher. The larger particle materials are returned to the impact crusher and crushed again; if finer products are required, the The crushed materials are sent to the sand making machine for further crushing. ?

The European version of the mill is the key equipment for limestone grinding after crushing. After crushing, the qualified materials are sent to the main grinding chamber evenly and continuously through the frequency conversion belt feeder for grinding. The ground materials are sent to the powder separator by the airflow of the fan for classification. Under the action of the analyzer, the materials that do not meet the fineness requirements fall into the grinding chamber for re-grinding, and the qualified materials enter the cyclone collector with the airflow through the pipeline Inside, it is separated and collected, and the finished powder is discharged through the discharge device. The separated airflow enters the fan through the return duct at the upper end of the cyclone powder collector. The system operates under positive and negative pressure, and the equipment is equipped with a pulse dust collector, which complies with relevant environmental protection standards.

MTW European version of the mill adopts a number of new patented technologies such as bevel gear integral transmission, internal thin oil lubrication system, arc-shaped air duct, etc., processing limestone powder, high grinding efficiency, more than 20% increase in output, low infrastructure cost, operation Low cost, single machine processing capacity up to 60T/H, economical investment. The price of limestone mill depends on the series of factors such as the discharge and output required by the customer, and there are tens of thousands, hundreds of thousands, or even higher.
