對輥式破碎機是破碎設備的一種， 因結構簡單， 方便維護， 性能穩定，能耗低， 經久耐用而廣泛使用在水泥， 化工， 電力， 礦山， 冶金， 建材， 耐火材料， 煤礦等各個領域。Double-roll crusher is one kind of crushing equipment, It has feature of simple structure, convenient maintenance, stable performance, low power consumption, durable and widely used in many areas such as cement, chemical,electric power, mining, metallurgical, building materials, refractory,coal, etc.

1.對輥破碎機設計合理， 機構簡單， 占空間小， 操作方便Double-roll crusher reasonable design, simple structure, small space occupation, convenient operation.
2.本機采用了**的機械結構設計和合理的動力匹配， 從而很大降低了電能的損耗，比其它規格破碎機節能30%左右。Adopts the optimal mechanical structure design and reasonable power matching, thereby greatly reducing the power loss,  about 30% energy saving than other crushers. 
3.內部裝有防塵板，密封性能好，避免了破碎后的細小物料的揚濺，粉塵少，工作噪聲低，工作環境有較大的改善。Equipped with dust-proof plate, good sealing performance, avoiding the broken tiny splash of materials, little dust, low noise, use a good environment
4. 磨料輥體重新進行優化設計，設備使用終身不需要換磨機輥體，而舊型對輥機使用一年就需拆開大修，更換輥體。Abrasive roller re optimize design, does not need to change the roller lifelong, while the old roller crusher use for one year would need to open repair, replace the roller. 
5.  本機磨輥上裝有可更換耐磨襯板，耐磨襯板采用國內先進耐磨材料，具有使用壽命長，不易損壞，方便維修等優點。連續使用壽命可達一年以上，磨損嚴重時，移開機蓋即可更換。維修量小，成本低。Equipped with a replaceable abrasion resistant lining plate, the wear-resistant liner using the domestic advanced wear-resistant materials, has the advantages of long service life, not easy to damage, convenient repair etc.. The continuous service life of up to one year or more, wear serious, remove the cover can be replaced. A small amount of maintenance, low cost.

6.  本機裝有安全防護裝置，當有意外金屬鐵件進入破碎腔后，防護裝置動作，鐵件漏出設備正常運轉。Equipped with safety protection device, when have unexpected metal iron into the crushing chamber, the protection device action, iron leakage equipment normal operation

7.  本機磨料輥體輥縫在1mm～20mm間任意可調，根據破碎粒度的要求調好輥縫后，破碎粒度能得到可靠控制，全部以理想粒度由破碎腔下方排出。the abrasive roller roll gap arbitrary adjustable in between 1mm ~ 20mm,according to the requirements of the particle size adjust the roll gap, crushing size can be get reliable controlled, all final products in an ideal size discharged from the bottom of crusher chamber.

8.  結構簡單合理，運行成本低，運轉平穩，高效節能，破碎效率高，破碎比大。Simple and reasonable structure, low running cost, stable running, high- efficiency and energy saving, high crushing efficiency,big crushing ratio.
9. 本機是低轉速高壓力對輥擠壓的工作原理。物料由破碎機上部垂直落入破碎腔里，由兩輥之間產生的強大壓力擠壓破碎下，物料大部分已經成為細小顆粒，剩余小部分顆粒狀物料的內部已經產生大量裂紋。在進一步粉粹過程中，可較大地降低粉磨能耗， 提高產量。the roller crusher is low speed high pressure roll extrusion working principle. Materials vertical falling into the crushing chamber from the upper crusher, was extruded and broken by strong pressure generated by the two roll, most of materials has become small particles, the remaining small particle materials inside has generated a large numbers of cracks. In the course of further crushing process, can greatly reduce the grinding energy consumption and improve production.
