Lightweight Expanded Clay Aggregate LECA Making Rotary Kiln Machine

Lightweight aggregate raw material is wide, it can be clay, mudstone, slate, coal gangue, fly ash, shale, sullage and the industrial waste, after crush and pellet, the raw material was fed to the rotary kiln, then come out to be the LWA. It is widely used in metallurgy, garding , chemical, construction etc field.

Henan DEWO Machinery Co.,Ltd. Was found in 1968, professional in LWA, Leca equipments manufacturing. We can supply the whole production line from design, machine developing, manufacturing, testing, quality guarantee, transport and after sale service, also we can accept the project by turnkey.

-          On purpose of steady output, we insist on integrade theory with practice, to make the standardization design and solution.

-          Improve the exist design, equipments and technology and connect with this solution.

-          Environmental friendly, add environment protect equipment, to realize non-dust product.

-          Insist on low cost, to be more competitive in economy and technology with other suppliers.

• Reduce the dead weight of a façade from 5 tons to about 3.5 tons
• Reduce craneage load, allow handling, lifting flexibility with lighter weight
• Good thermal and fire resistance, sound insulation than the traditionalgranite rock
• Allow design and construction flexibility for larger prefabrication modules
• Allow maintenance flexibility with replaceable modules
• Factory production of module enhances quality of product
• Enhance speed of construction, shorten overall construction period
• Enhance green building construction, minimize wet trade on site
• Improve damping resistance of building
• Utilization of PFA in aggregate production resolves the waste disposal

First the raw material will be grinding to 100 around 100mesh, and then mix in the mixer with bond , carried by the belt conveyor to the disc granulator for pellet making, and then feed to the trommel screen to select the right size calcinations in the kiln, while the size which not suitable will back to pellet again. Materials stocked in the hopper, carried out by conveyor to the rotary kiln for calcination, and after came out, fed to the cooler, the hot gas from the cooler back to the kiln for second use, the final products waiting for package after separation by the screen, the dust from the kiln collect by the dust catcher, and the waste gas after purify back the air. The whole flow chart made by our company, both engineer saving and environment friendly.
