Ceramic sand rotary kiln

Ceramic Pellets Rotary Kiln

Ceramic pellet kilns are categorized into two main types: straight-tube rotary kilns and plug-in rotary kilns. Plug-in rotary kilns are further divided into two sections: a preheating kiln and a roasting kiln. The preheating kiln is used to dry and preheat the raw ceramic pellets, while the roasting kiln is used to calcine the finished product. These kilns are critical equipment in ceramic pellet production, offering high operational flexibility, high efficiency, stable operation, low heat consumption, long service life, and stable operating conditions.

Applicable Materials: Clay, shale, domestic sewage sludge, municipal sewage sludge, riverbed sludge, lakebed sludge, industrial sludge, leather sludge, electroplating sludge, construction waste, construction piling mud, sand washing sludge, pickling sludge, printing and dyeing sludge, papermaking sludge, oil well sludge, red mud, silt, contaminated soil, fly ash, slag, coal gangue, drilling cuttings, raw materials for old brick factory renovation, etc.

Fuel: Biomass (rice husk) pellets, coal, coal gas, natural gas, etc.

Application: Primarily used for the calcination of ceramsite

Ceramic Porcelain Rotary Kiln Product Introduction

Ceramic porcelain, a new environmentally friendly material, has been widely used in the construction industry. It can be made into new wall materials such as wallboard and bricks, as well as for thermal insulation, floor slabs, lightweight concrete, and water treatment and purification. As a key piece of equipment in the production of ceramic porcelain, the performance of the rotary kiln directly impacts the quality and production cost of the finished ceramic porcelain.

Highlights

1. The rotary kiln utilizes variable frequency drive for high efficiency and low power consumption.

2. Low fuel consumption per unit product, negative pressure operation, and minimal dust pollution.

3. Simple process flow, simultaneously completing drying, granulation, and calcination.

4. Compact layout, lightweight system equipment, and low investment.

Working Principle

Semi-finished pellets are fed into the preheating kiln through a chute at the kiln's tail (high end). Due to the kiln's tilt and slow rotation, the semi-finished pellets roll circumferentially and move axially from the preheating kiln's tail (high end) toward the kiln's head (low end). Fuel is injected into the kiln through a burner at the kiln's head (low end) for combustion, transferring heat to the semi-finished pellets through radiation, convection, and conduction. During this process, the semi-finished pellets are dried and preheated before entering the kiln for roasting, undergoing various physical and chemical reactions to form ceramsite. They are then discharged from the kiln's head into a cooler. High-temperature flue gas enters the kiln's tail dust removal system at the kiln's tail end.
