产品概述
Product introduction
PYY系列单缸液压圆锥破碎机适用于大、中型砂石、矿石加工企业，作矿石、岩石或岩基材料的二级、三级或四级破碎。其破碎过程是由受偏心套驱动的偏心旋摆的破碎壁和轧臼壁完成的。物料通过上部的进料斗进入破碎腔，破碎后由下部排出，经出料斗收集排出。具有产量高、使用成本低、结构精巧、操作简单、维护少、适用范围广、使用率高的优点。
PYY series single-cylinder hydraulic cone type crushers are suitable for medium and large sized sand and mineral processing enterprise. They are used for crushing class 2, 3, or 4 mineral, rock and bedrock material. When it crushes materials, the crushing wall and rolling wall are driven by the deflection sleeve to complete the process. Material enters the crushing chamber through the upper hopper and is discharged after crushing and collected by another hopper. This series is characterized by high capacity, low cost, delicate structure, easy operation, less maintenance, broad application and high efficiency.
产品特点。
Product characteristics
1、 适用范围广。可破碎较为坚硬的岩石，同一主机通过更换衬板即可取得多种腔形，从而适应各种应用场合。中碎型拥有稳定而较大的给料口，用于物料的二级破碎（甚至粗破）。
1. Broad application. It can crush relatively harder rock. The main engine can have chambers of various shapes by changing the liner plate, so it can be used in many situations. Medium crushing type has stable and large hopper and can be used for class 2 crushing (even coarse particles).
2、产品粒形好。优化组合的破碎频率、偏心距，以及层压破碎，使排料口尺寸的破碎料保持较好的产品粒形。
2. Products have good shape. The optimized crushing frequency, eccentricity and laminated crushing make the crushed material at the hopper maintain good shapes.
3、生产成本更低。优化的衬板设计使单位钢耗更低；层压破碎和挤满给出料使设备作业率更高。
3. The production cost is lower. Optimal design of liner plate reduces unit steel consumption. Laminated crushing and discharge of material increases operating efficiency.
4、操作维护简单。只需按钮控制，即可利用液压力实现排料口的无级调整，且可在生产过程中进行，使操作更直观。经精加工后磨损件，装配时无需填料。
4. Maintenance is simple. Button control can use hydraulic pressure to realize stepless adjustment of the hopper. It can be carried out during the production to make operation simple. After fine finishing, the wear part needs not to be packed in assembly.
5、自动化程度高。
5. High degree of automation
表格中生产能力和筛分曲线仅用作参考，只适用于容重为1.6t/m3 的中硬度花岗岩类石料在挤满破碎腔时的参数，其它物料的参考产量可近似通过容重换算求得。
The production capacity and sieve curve in the form is only for reference and only as the applicable parameters when medium hardness granite stone of 1.6t/m3 is packed in the crushing chamber. Reference production for other aggregates can be determined by volume weight.
不同腔形、冲程，适用的排料口范围不同，从主参数表中找出允许排料口大小并与生产能力的参考结合，最大排料会在破碎壁和轧臼壁磨损后变大。
Different chambers and strokes have different hoppers. Permissible hopper sizes can be found in the main parameter form in combination with production capacity. The maximum discharge will become larger after wear and tear of the crushing wall and rolling wall.
