A roller crusher handles controlled size reduction in ore processing—ideal for medium-hard ores, cuts slimes, and boosts recovery. Learn its uses & optimize your circuit with Huashengming’s solutions. What Does a Roller Crusher Do in Ore Processing? In ore processing circuits, size reduction equipment (like the roller crusher) plays a pivotal mid-stage role. The roller crusher focuses on controlled particle sizing: it takes ore from primary crushers (like jaw crushers) and refines it, prepping the material for later liberation and beneficiation steps. As a secondary or tertiary crusher, it bridges the gap between rough crushing and final grinding, ensuring the ore is primed for downstream processing. Ideal Ores for Roller Crusher Applications This comminution tool excels with medium-hard ores: phosphate, manganese, certain iron ore varieties, and coal. Its core mechanism relies on two counter-rotating rolls that apply high-pressure compression. Unlike impact crushers (which generate excess dust), this design minimizes ultra-fine “slimes”—the dusty material that clogs flotation cells and disrupts separation processes. The result? A uniform, granular product that lets minerals separate more cleanly, directly lifting overall ore recovery rates. Optimizing Processing Circuits with Roller Crushers A key feature of this crushing device is its adjustable roll gap. Plant operators tweak…

The double-stage crusher is a new type of crushing equipment upgraded and improved on the basis of the traditional hammer crusher, also known as the screenless double-stage grinder. With its unique design, it has become an ideal choice for processing high-moisture materials. Its core structure consists of two sets of series-connected rotors, which is equivalent to combining two hammer crushers into one. Coupled with high-alloy wear-resistant hammer heads, it realizes efficient crushing operations. Double-Stage Crusher: The Preferred Equipment for High-Moisture Material Crushing During operation, two motors drive the two sets of rotors to rotate at high speed. When materials enter the cavity, they are first coarsely crushed by the upper rotor and then finely crushed again by the lower rotor. The mutual collision between materials creates a crushing effect of “hammer crushing material and material crushing material”. The discharge particle size can be stably controlled below 3 mm. With particles smaller than 2 mm accounting for more than 80%. The key advantage of this equipment lies in its screenless grate bottom design, which solves the problem of clogging caused by high-moisture materials. Even if the materials have high water content or are even water-bearing, it can operate normally on rainy…
The impact crusher, commonly known as a sand making machine, is a high-energy and low-consumption crushing equipment with internationally advanced standards. Relying on its unique crushing principle, it has become a core piece of equipment in the field of fine ore crushing and manufactured sand production. During operation, materials fall vertically from the upper part into the high-speed rotating impeller. Driven by centrifugal force, they collide at high speed with the target stones around the impeller. Then, a vortex is formed between the impeller and the machine shell. The materials are crushed through multiple mutual collisions and friction, discharged from the lower part, and their particle size is controlled by screening equipment. The impact crusher is a core piece of equipment in the crushing field. This equipment adopts a material self-impact crushing mode, which avoids direct contact with metal components. This not only reduces material contamination but also extends the service life of wearing parts. Combined with the self-circulation design of airflow in the vortex chamber, it effectively eliminates dust pollution. Its crushing ratio can reach over 50, and the finished products feature excellent particle shape with a needle-like and flaky content of less than 10%. It is widely used…
