Ceramic sand, also known as ceramic particles, is a kind of sand made from a mixture of various solid wastes such as clay, schist, coal gangue, etc. Ceramic sand is not a waste in the traditional sense. After reasonable processing, it can be used to make thermal insulation materials, sewage purification agents, etc., with a wide range of applications.

The processing of ceramsite sand is inseparable from the calcining operation of the ceramsite sand rotary kiln. There are many domestic manufacturers of ceramsite sand rotary kilns. The editor here recommends the Xingyang Mining Machinery Manufacturing Factory in Henan Province. This manufacturer has strong production strength and produces The rotary kiln calcines materials with high efficiency and good results, making it a great value for money for customers. Below we will introduce the structure and start-up steps of the Yingkuang Machinery Ceramic Sand Rotary Kiln.

As the ceramsite sand market becomes increasingly popular, more and more users are investing in ceramsite sand production lines. Users should all know that ceramsite sand is a proppant for oil mining, and the processed ceramsite sand can also be used in construction, gardening, chemical industry and other sectors, so the demand for this equipment and domestic ceramsite sand is large. In the complete set of ceramsite sand production line equipment, the ceramsite sand rotary kiln is an indispensable calcining equipment. The ceramsite sand processed by the rotary kiln has a good market prospect. The market demand has promoted the majority of users to invest. Therefore, There are also many users who want to invest in ceramsite sand rotary kiln equipment.

Henan Xingyang Mining Machinery Manufactory(XKJ GROUP) has a very good calcining function for ceramsite (ceramic particles). The roasted ceramsite is light in weight, corrosion-resistant, and has good heat insulation, and can be used very well. Used in the market, it is an ideal calcining equipment for the majority of users. The ceramsite sand rotary kiln produced by our company can also be used for calcining a variety of materials. It is a rotary cylinder equipment and has good effects in metallurgy, construction refractory materials, chemical industry and other fields. Therefore, this equipment is very popular in the market. .

The ceramsite sand rotary kiln consists of a rotary cylinder, a supporting device, a supporting device with a blocking wheel, a kiln head and kiln tail sealing device, and a coal injection pipe device. The kiln body is at a certain inclination to the horizontal. The entire kiln body is supported by a supporting wheel device and has a wheel blocking device that controls the up and down movement of the kiln body.

In addition to the main transmission, the transmission part is also equipped with an auxiliary transmission device to ensure that the kiln body can still rotate slowly and prevent the kiln body from deforming when the main transmission power supply is interrupted. The kiln head adopts a shell seal, and the kiln tail is equipped with an axial contact sealing device to ensure the reliability of the seal.

The technology of calcining ultra-fine kaolin at medium temperature (950°C ~ 1050°C) in a thermal rotary kiln with ceramsite sand is mature and represents the development direction of ultra-fine kaolin calcination technology. This calcining technology has low energy consumption and high output. The product is dehydrated, decarburized and whitened. It has high unit volume, long kiln life, high operating rate, stable operation, high heat transfer efficiency, and low heat consumption. Therefore, the equipment Widely used in ferrous metallurgy, non-ferrous metallurgy, chemical industry, building materials, non-metallic minerals, refractory materials, papermaking, environmental protection and other industries.

Then some users have questions about starting the equipment. Today, how to start the ceramsite sand rotary kiln? XKJ GROUP will divide it into four stages. For details, see the following steps:

1. In the front heating stage, the kiln is ignited and the kiln head of the ceramsite sand rotary kiln is heated by coal tar injection and combustion. The front heating stage includes five stages of heating-insulation-heating-insulation-heating, so that the ceramsite sand rotary kiln Heating according to the set heating curve; that is, when the temperature of the ceramsite sand rotary kiln is heated to 120±10℃, it stops heating and switches to heat preservation. After a period of heat preservation, it continues to heat up. When the temperature of the ceramsite sand rotary kiln is heated to 240±10℃ °C, stop heating and switch to heat preservation. After a period of heat preservation, continue to heat up until the temperature of the ceramsite sand rotary kiln is heated to 290-310℃; the heating rate in the heating stage is (6-16)℃/hour and the temperature in a single heat preservation stage is The time is longer than that of a single heating phase.
2. In the second heating stage, coal tar combustion is used to continue heating the kiln head of the ceramsite sand rotary kiln. At the same time, petroleum coke is intermittently added from the end of the kiln to auxiliary heating the ceramsite sand rotary kiln. The second heating stage includes The four stages of heating-insulation-heating-insulation make the ceramsite sand rotary kiln heat up according to the set heating curve; that is, when the temperature of the ceramsite sand rotary kiln is heated to 360±10℃, it stops heating and switches to insulation, and keeps it warm for a period of time. Then continue to heat until the temperature of the ceramsite sand rotary kiln is heated to 450±10℃, and then keep warm for a period of time; during the heating process, adjust the input amount and dosage interval of petroleum coke so that the heating rate is within (6-16)℃/ hours, and the time of the secondary heat preservation stage in the second heating stage is longer than the time of the single heating stage, and the time of the second heat preservation stage is half of the time of the secondary heat preservation stage.
3. In the third heating stage, the coal tar combustion method is used to continue heating the kiln head of the ceramsite sand rotary kiln, and gradually reduce the supply of coal tar. At the same time, petroleum coke is continuously input from the end of the kiln to heat the ceramsite sand rotary kiln. Heating, when the temperature of the ceramsite sand rotary kiln reaches 550-620°C, stop using coal tar combustion for heating, and only use the method of continuously inputting petroleum coke from the end of the kiln to heat the ceramsite sand rotary kiln.
4. In the fourth heating stage, continue to use petroleum coke from the end of the kiln to continuously heat the ceramsite sand rotary kiln. When the temperature of the ceramsite sand rotary kiln reaches the calcining temperature of the ceramsite sand rotary kiln in normal production, it is completed. Ceramic sand rotary kiln started.
