Types of Calcium Oxide Machines in China

A calcium oxide machine or quicklime kiln manufactures calcium oxide (CaO) by thermally decomposing calcium carbonate (CaCO3), commonly known as limestone. These are some types of calcium oxide machines that business buyers can get.

• Rotary Lime Kiln Machine

  The rotary lime kiln machine (or rotary kiln lime machine) is popular among businesses, accounting for about 75% of production. It has a horizontal position and a slightly inclined angle, which makes excellent quality quicklime. The length and diameter are large, and high-temperature products come out. The feeding is at the higher end, while the discharging is at the lower end. It also uses coal, natural gas, and petroleum as fuel sources.

• Vertical Lime Kiln Machine

  The vertical lime kiln machine has fixed shafts. It is more straightforward than the rotary type. The vertical kiln quicklime machine relies on natural draughts to get the intense heat needed for calcining. Though the design is old and simple, the quality of lime produced is not so good. There are some variants of this type, including the annular and compound types.

• Fired Lime Reactor

  The fired lime reactor machine is big and round. It can produce hydrated lime and quicklime. It comes with an advanced air and gas handling system with precise controls to handle dust. The kiln can operate well in batch or continuous modes. There is little air pollution from it, and the technology is eco-friendly.

• Hydrated Lime Plant

  A hydrated lime plant uses calcium oxide or quicklime to produce hydrated lime. The plant has a slaking machine that adds water to quicklime. It also has a conveyor and classifier. The classifier helps to separate fine hydrated lime from big particles. Then, the conveyor sends big particles back to the slaker for more processing. The hydrated lime plants' end products are fine dry powders that go into the building and construction industry.

• Active Lime Kiln Machine

  The active lime kiln machine produces active lime or reactive lime. This type is good for making steel and iron, and other industrial uses. The design of the active lime kiln machine is more modern than older vertical kilns. It works well and is cost-effective for large-scale production.

Specifications and maintenance of calcium oxide machine China

Different types of lime machines for sale have varying specifications depending on their models and designs. The table below highlights some general specifications one will come across when searching for a calcium oxide machine on Alibaba.

• Production Capacity

  The production capacity of a lime machine for sale indicates the volume of lime it can produce per hour or day. This capacity varies depending on the size and design of the machine. During the search for lime machines for sale, buyers will discover that small lime machines produce 1 to 5 tons of lime per day, while larger machines produce 20 to 100 tons per day.

• Power Consumption

  A calcium oxide machine requires different powers to produce quicklime, depending on its production capacity and the type of fuel it uses. The power consumption is measured in kilowatts per hour (kWh). A small machine will use up to 50 kwh daily, while larger machines use 1000 kwh and above.

• Operating Temperature

  The operating temperature of a lime machine indicates the temperature range that the machine can handle during the lime production process. Different machines have different operating temperatures. For instance, the temperature range of a rotary calcium oxide machine China is between 900 and 1200 degrees centigrade.

• Dimensions

  The dimensions of the lime machines indicate the physical size of individual machines. The dimensions are described in length, width, and height. A lime machine with large production capacity has huge dimensions. For instance, the vertical calcium oxide machine for sale has a height of more than 50 meters, and a length of 10 meters.

Maintenance of calcium oxide machines

Just like any other piece of equipment used in industrial production, a calcium oxide machine requires regular maintenance to ensure effective and smooth performance and to prolong its lifespan. Below are some general maintenance tips that can be used to ensure the calcium oxide machine is in good operating condition.

• Clean the calcium oxide machine China regularly to remove residues, pollutants, impurities, or materials that can clog its components, affecting its performance.
• Second, it's important to lubricate movable parts of the lime machine periodically, including gears, bearings, chains, and more. Lubricating the moving parts prevents wear and tear and reduces the machine's operating noise level.
• Third, users should check the water and air pressure connections before starting the machine to ensure they are tight and there is no leakage. This helps the machine to operate smoothly and avoid accidents.
• Due to the high operating temperatures of a lime machine, users should periodically inspect the equipment for signs of wearing, overheating, and leaking. Early detection of these issues prevents costly downtime and the outbreak of accidents.
