As a core piece of equipment in the field of crushing medium- to low-hardness brittle materials, the double-toothed roll crusher holds a significant position in industries such as coal, mining, building materials, and chemicals, thanks to its unique design and performance. Its core structure consists of two parallel-arranged toothed rolls that achieve stable counter-rotation through synchronous gears. It completes material crushing by utilizing the shearing, stretching, and extrusion actions between the toothed rolls, with a crushing ratio of up to 5-8, producing uniformly sized output with a low rate of over-crushing.
Double-Toothed Roll Crusher: An Industrial Crushing Powerhouse
The technical advantages of this equipment are remarkable: it employs a hydraulic spring overload protection system that automatically retreats when encountering hard objects, preventing equipment damage; its spiral tooth arrangement design and V-shaped crushing chamber structure accommodate materials with varying moisture and viscosity levels; the hydraulic roll gap adjustment function enables precise particle size control, while the intelligent cleaning system reduces material adhesion. The wear-resistant alloy toothed rolls and high-strength crushing chamber design, combined with its low-speed operation characteristics, significantly reduce wear and noise, lowering maintenance costs by over 30% compared to traditional equipment.
In practical applications, the double-toothed roll crusher can handle feed materials ranging from 150-300mm in size, with adjustable output particle sizes ranging from 20-80mm. It is particularly suitable for crushing complex materials such as raw coal containing gangue and recycled aggregates from construction waste, providing reliable support for industrial production.
