I.What is a roller crusher?
The roller crusher, also known as a double-roller sand making machine, is a device that makes sand by squeezing materials through two rotating roller wheels. It has a simple structure, consisting of roller wheels, bearings, adjustment devices, and driving motors. It is widely used in fields such as construction waste treatment and sand and stone production, and can turn large pieces of material into uniform sand particles.
II. Crushing process: Crushing materials like scissors
Material enters between the two rolls from above. Into the crushing chamber: the rolls rotate towards each other, and the friction force “pulls” the material into the crushing area. Compression and shearing: the material is compressed and rubbed by the rolls, and is crushed like scissors. Hard objects are repeatedly crushed until they break. Discharge: The crushed sand particles are discharged from the bottom, and the particle size is controlled by the gap between the rolls.
How to adjust the size of the sand particles?
Wedge adjustment: Turn the bolt, lift the movable roll, increase the gap, and the sand particles become coarser. Gasket adjustment: Increase or decrease the number of washers to change the gap; the more washers, the coarser the sand particles. Intelligent control: Some new equipment supports hydraulic or digital adjustment, allowing for one-click particle size adjustment.
Advantages: Energy-saving, flexible, and environmentally friendly
Energy-saving: Single motor drive, only 1.68 degrees of electricity per ton of sand. Versatile for both dry and wet: no clogging when adding water and no dust pollution. Handles a variety of materials: from construction waste to river pebbles, over 200 types of stone can be crushed. Long lifespan: roller wheels are made of wear-resistant materials, with low maintenance costs.
V Application scenarios: The “Magician” that turns waste into treasure
Construction waste recycling: Crush concrete blocks into sand and gravel below 5mm for road paving. Substitute for natural sand: produce uniformly graded manufactured sand to alleviate the shortage of natural sand. Industrial raw material processing: crush coal gangue, quartz stone, etc., for use in the chemical and metallurgical industries.
VI Usage precautions
Iron removal and damage prevention: Mixed metal in materials can damage roller wheels, and iron separators need to be installed in advance. Regular maintenance: Check the lubrication of the bearings and replace worn roller surfaces in a timely manner. Avoid overloading: Large pieces of material should be pre-crushed to prevent equipment from jamming.
The roller crusher achieves efficient sand production through simple mechanical principles. Whether it is for the regeneration of construction waste or the processing of natural ore, it can cut as accurately as a “scissors,” providing high-quality sand and stone for modern industry. When choosing, the particle size can be adjusted according to production needs, balancing efficiency and environmental protection.
