The equipment adopts a quasi-static crushing principle of “compression + shearing.” Materials fall from the upper feed inlet between the two rollers and are drawn into the crushing chamber by friction. Under the strong compressive force, the materials are crushed layer by layer, and the qualified particles are naturally discharged by gravity. Unlike traditional high-speed impact crushing, this “rolling instead of striking” method significantly reduces the over-crushing rate, precisely converting mechanical energy into crushing kinetic energy.
Double Roll Sand Making Machine Production Site
Precise and Adjustable Discharge Size: The equipment is equipped with advanced hydraulic or wedge adjustment devices. Operators can precisely control the gap between the two rollers according to their needs, easily achieving stepless adjustment of 0-5mm or even finer sizes to meet the production requirements of various manufactured sand specifications.
Plump and Excellent Product Shape: Due to the static pressure extrusion molding, the manufactured sand produced is mostly plump and cubic, with reasonable gradation and an extremely low content of needle-like and flaky particles. It perfectly meets the requirements of high-standard commercial concrete and infrastructure projects.
Super Wear Resistance & Low Operating Costs: The core roller skins are made of a patented high-chromium manganese steel composite wear-resistant material and undergo a centrifugal casting process, which greatly extends their service life. This significantly reduces downtime and consumable costs caused by frequent replacement of wearing parts.
Intelligent Hydraulic Overload Protection: When encountering hard, uncrushable foreign objects such as iron blocks, the hydraulic system will instantly yield, widening the roller gap to allow the foreign objects to be safely discharged, and then quickly reset automatically. This completely eliminates the risk of jamming and ensures continuous production.
Dual Dry and Wet Use, No Sticking or Clogging: The unique screenless bottom design allows it to process materials with high moisture content or a certain degree of stickiness (such as wet coal gangue and quicklime) without any obstruction, thoroughly solving the clogging pain points of traditional equipment.
