Product Introduce

Roller Crusher (LN crusher) is to use the principle of continuous shearing, milling and extrusion mixed crushing technology to effectively crush stone. It has the advantages of large crushing ratio, high production efficiency, low energy consumption, less fine powder, uniform particle size, beautiful particle shape, etc. Mainly used for crushing construction aggregate 16-31.5mm, 10-20mm gravel, flux limestone gravel (such as 40-80) and other processes with less fine crushed materials in crushed stone products.

FEATURES AND BENEFITS OF ROLLER CRUSHER (LN CRUSHER)

High yield, less fine crushed materials, improved resource utilization

For building aggregate, the proportion of 0-5mm stone powder is less than 15%. For flux limestone, 50-80mm stone accounts for more than 50%, 40-80mm stone accounts for more than 60%, and 0-5mm stone powder accounts for less than 6%.

Grain shape regularity

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.

Energy conservation

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).

High compressive and shear strength

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.

Reduced investment and O&M costs of equipment in the rear section of the production line

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.

Clean finished aggregate and reduced concrete mixing cost

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 & Hydracascade technology

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.

Simple maintenance, low cost of consumables

Roller Crusher (LN crusher) adopts low-speed crushing. Wearing parts are made of alloy materials and treated with advanced technology (good toughness and wear resistance), ensuring easy and fast replacement.

Frequently Asked Questions

Q1: What is the crushing principle of the Roller Crusher (LN crusher)?

The Roller Crusher (LN crusher) utilizes the principle of continuous shearing, milling, and extrusion mixed crushing technology to effectively crush stone.

Q2: What are the main applications of this Roller Crusher?

It is mainly used for crushing construction aggregate (16-31.5mm, 10-20mm gravel), flux limestone gravel (such as 40-80mm), and other processes that require fewer fine crushed materials in crushed stone products.

Q3: How does the LN crusher achieve energy conservation compared to traditional crushers?

Unlike traditional surface contact crushing, the new LN crusher uses point contact crushing. The crushing force acts directly on the pressure concentration points of materials, greatly reducing power loss and the overall installed capacity.

Q4: What is the fine powder proportion for building aggregate and flux limestone?

For building aggregate, the proportion of 0-5mm stone powder is less than 15%. For flux limestone, 0-5mm stone powder accounts for less than 6%, while 40-80mm stone accounts for more than 60%.

Q5: How does the equipment reduce concrete mixing and operation costs?

Because the finished aggregate is cleaner with less attached fine powder, concrete plants do not need to add extra cementitious materials (like cement) when mixing. Additionally, the reduction of fine particles decreases the need for later-stage dust control and stone powder treatment equipment, lowering investment and O&M costs.

Q6: What technology is used to manage product shape and throughput?

It utilizes a patented feed adjustment device and Hydracascade feed technology to provide accurate control of the ratio between central feeding and the cascade, which improves energy availability, increases throughput, and manages product shape and fines content.
