100 000sq m per year LECA expanded clay production plant

LECA (Lightweight Expanded Clay Aggregate) is an aggregate made of expanded clay at average 1200 C° in rotary kiln, the Yielding gases are expanded by thousands of small bubbles as long as this temperature and those will be provide many voids and honeycombs at these round shape aggregates when melted materials become cold.

The manufactured aggregates are produce in various sizes; Four usual grades are (0-4) mm, (4-10) mm, (10-25) mm and mix grade 0-25 mm which has 350-700kg/m3 density, LECA boulder is a the bigger size of LECA with 100-500 mm size and 500 kg/m3 density.

Material for LECA Production:

Clay

SHale stone

Fly ash

City waste sludge

Shale Stone LECA Production Process:

Shale Stone---crushing---separating---calcination---cooling--separating---packing.

Following is the description Shale LECA:
1.crushing The size of SHALE from mine is around 300~500mm, low moisture, After two-stage crushing which is composed by Jaw crusher and hammer crusher, the size of shale will be 5-25mm.

2. Dosing shale and separating into different size.

3.Calcining Raw Material  in rotary kiln , with the revolution and slope of rotary kiln, calcined ceramic sand move toward to the kiln head, meanwhile, pulverized coal (or gas)spray into the kiln burner from kiln head.

4.Screening Ceramin sand after the cooler can be directly transported to multistage vibrating screen, it can be divided into many particle grade according to requirements. skype: gary102884     webchat:gary10288   whatsapp:+8615617816797
