Ceramic Rotary Kiln

The ceramic rotary kiln is a rotating cylindrical equipment that integrates material preheating, drying, and firing. It is primarily used for the calcination of ceramic pellets. The ceramic pellet kiln features a high volumetric capacity, long service life, high operational efficiency, stable operation, high heat transfer efficiency, and low energy consumption. There is no doubt that ceramic pellet rotary kiln is an ideal equipment for calcining ceramic pellets.

    The components of Ceramic Rotary Kiln: cylinder, feeding device, supporting device, supporting device with baffle wheel, kiln head, kiln tail sealing device, combustion device, dust removal device, motor and other parts.

    Working Principle

    In a ceramic pellet rotary kiln, pulverized coal is burned to produce heat, which is used to heat the material by means of gas conduction or radiation. Meanwhile, the ceramic pellet rotary kiln continuously rotates at the designed inclination and speed, causing the raw materials to periodically tumble and advance, being conveyed from the feeding end to the discharge end. In the process of raw material passing through the rotary kiln, the raw material is calcined into qualified clinker.

    Applications of Ceramsite

    Ceramsites are lightweight aggregates produced in a rotary kiln. Ceramic pellets have several excellent properties, such as low density, high cylinder strength, high porosity, high softening coefficient, good frost resistance and resistance to alkali aggregate reaction. It’s widely used in building materials, horticulture, food and beverage, refractory insulation materials, chemical and petroleum fields.


    Simple Structure and High Efficiency
    Ceramic pellet rotary kiln has the advantages of simple structure, high unit volume, high operation rate, stable operation, high heat transfer efficiency and low heat consumption.
    Automatic Control and Over-temperature Alarm Reminder, Safe to Use
    It’s safer to use ceramic pellet rotary kiln with automatic temperature control and over-temperature alarm function. And it can make full use of the waste heat of the secondary air intake.
    Stable Operation and High Output
    The kiln head and tail sealing technology and devices are one of the distinguishing features of ceramic rotary kilns, which ensure operational stability and high production. At the same time, the application of these sealing technologies and devices effectively prevents the leakage of material and heat and provides good sealing performance.
    Long Product Life Span, Reduce Costs
    Shanghai YingYong Machinery's ceramic pellet rotary kiln is manufactured with high quality material selection and fine craftsmanship, which enable these rotary kilns have a long service life,and effectively reduces the cost of maintenance and replacement.Meanwhile, with its robust construction, the kiln can withstand demanding conditions of high temperatures and heavy workloads while maintaining reliable and stable performance.
