Introduction

LECA (Light Expanded Clay Aggregate) as a new environmental protection material is widely used in the construction field. It can be made of wallboard, brick and other new wallboard material. It also can be used for insulation, floor, lightweight concrete, water treatment and etc.

LECA Rotary Kiln (Ceramsite Kiln) is mainly used for calcining semi-finished ceramsite particles, which has two types: single-tube rotary kiln and double cylinder plug-in rotary kiln. Among them, the double cylinder plug-in rotary kiln has two types: preheating kiln and roasting kiln. The preheating kiln is used for drying and preheating, and the roasting kiln is used for firing. It is widely suitable for sludge, clay, yellow mud, river bottom sludge, fly ash, The calcination and production of ceramsites of various materials such as shale and slag; it is also a key equipment in the ceramsite production line, with high unit volume, long kiln life, high operation rate, stable operation, high heat transfer efficiency, low heat consumption, etc. It is characterized by ideal ceramsite calcining equipment.

LECA Rotary kiln is the key equipment in the LECA production. The performance will effect the final LECA quality and production cost directly. We offer Clay Expanded Aggregate Production, Sludge Expanded Aggregate Production, Fly Ash & Sludge Expanded Aggregate Production by raw material, with different production process.

Features

1. Rotary kiln drive adopts frequency conversion speed regulation, high efficiency and low power consumption

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

3. The process flow is simple, and the drying, granulation and calcination are completed at the same time

4. Compact layout, light weight of system equipment, low investment
