China Roller Crusher Factory - Reliable Suppliers for High-Quality LN Crushers

For building aggregate, the proportion of 0-5mm stone powder is less than 15%.

Meet the requirements of high-quality concrete on aggregate grain size and the requirements of flux limestone on air permeability when calcining in the kiln.

Different from the traditional surface contact crushing, the new LN crusher uses point contact crushing. The crushing force acts on the pressure concentration of materials, greatly reducing the power loss (Greatly reduce the installed capacity of traditional crusher).

There are few and shallow micro cracks on the surface of finished aggregate products, and with high compressive strength and shear strength of finished aggregate products.

Due to the substantial reduction of fine particles and powders in the finished products, the dust control and stone powder treatment equipment in the later stage are reduced, which reduces the equipment investment. At the same time, the installed capacity of dust control and stone powder treatment equipment is reduced, which greatly reduces the production, operation and maintenance costs.

In aggregate production, water mist is often used for dust removal. In the case of crushing, more fine powder will be attached to the aggregate surface, and the concrete plant will respond by adding cementitious materials (cement, etc.) when mixing, which will indirectly increase the cost of concrete; At the same time, the flux limestone material does not need to be cleaned.

Patented feed adjustment device provides an accurate control of ratio between central feeding and the cascade. Hydracascade feed technology not only improved energy availability and increased throughput, but also managed product shape and fines content via cascade feed.
