Hydraulic roller crusher Roller crusher, also known as roller sand making machine or roller crusher, is a kind of mechanical equipment that uses two relatively rotating crushing rollers to extrude, shear and grind materials, so as to achieve crushing. The roller crusher is suitable for processing ore, rock, sand, coal and other materials with medium hardness and below hardness, and is widely used in mining, sand and gravel aggregate production line, metallurgy, chemical industry, building materials and other industries.
In the production of manufactured sand, the role of the roller crusher is particularly prominent:
Fine crushing and sand making: The roller crusher can finely crush the materials after the initial crushing, and crush the materials into particle sizes that meet the standards of construction sand, so as to produce high-quality machine-made sand. Particle size control: By precisely adjusting the gap between the two rollers, the discharge particle size can be flexibly controlled to meet the requirements of different sand and gravel aggregate products for particle size.
Low energy consumption and high efficiency: Due to its unique crushing principle, the roller crusher has the characteristics of low energy consumption and high crushing efficiency compared with other types of crushers, especially when dealing with medium and hard materials.
Wear-resistant and durable: The crushing drum of the roller crusher is usually made of wear-resistant materials, which can resist the strong wear of materials and ensure the stability and durability of the equipment under long-term and high-load work.
Environmental protection and energy saving: In the working process, the roller crusher produces less dust and less noise, which meets the requirements of modern sand and gravel production industry for environmental protection and energy saving.
In short, in the production of manufactured sand, the roller crusher plays a crucial role in fine crushing and particle size control, and is one of the key equipment to ensure the quality of manufactured sand, improve production efficiency and reduce production costs.
