Evaluating the performance of a crusher requires focusing on core technical indicators, which directly determine the efficiency, cost and finished product quality of the crushing line. The key indicators are as follows:
1. Crushing Ratio
Definition: The ratio of the maximum particle size of the feed material to the maximum particle size of the finished product, reflecting the material reduction capacity of the crusher.
Calculation method: Crushing ratio = Maximum feed particle size ÷ Maximum finished product particle size.
Application: Hard rock (granite, basalt) requires a higher crushing ratio (8-12), while soft rock (limestone) requires a lower ratio (4-8).
2. Production Capacity
Definition: The quality or volume of materials processed by the crusher per unit time, usually expressed in t/h (tons per hour).
Influencing factors: Feed particle size, material hardness, discharge gap setting, and crusher type.
Standard: The actual capacity should be 80%-90% of the rated capacity to ensure stable operation.
3. Power Consumption
Definition: The electrical energy consumed by the crusher to process unit mass of materials, expressed in kWh/t.
Key point: Lower power consumption per ton indicates higher energy efficiency; it is closely related to the crusher structure and material properties.
Optimization: Choosing energy-saving models (e.g., hydraulic cone crushers) and optimizing discharge gaps can reduce power consumption.
4. Product Particle Shape
Definition: The appearance and gradation of the finished aggregate, including cubical degree, flaky particle content and particle size distribution.
Standard: For high-standard construction projects, the flaky particle content should be less than 15%, and the cubical degree should be more than 80%.
Influence: Good particle shape improves the workability and strength of concrete.

The user purchased two sets of sand production line, each set of equipment includes ZSW490*110 vibrating feeder, PE750*1060 jaw crusher, HST250 single-cylinder cone crusher, JYS1238 sand making machine, YK2460 vibrating screen, 3016 sand washer and so on.
The designed capacity of this sand making project is 200t/h, and the equipment used includes 490*110 vibrating feeder, PE750*1060 jaw crusher, PF1315 impact crusher, 9928 sand making machine, two sets of 2460 vibrating screen, two sets of 920 single screw sand washer, two sets of XSD2816 sand washer, two sets of dewatering screen, and several belt conveyors.
Project configuration: Jaw Crusher PE900*1200, Cone Crusher HST315T, Vertical Shaft Impact Crusher VSI6X1263, Heavy Duty Vibrating Screen 2YKZ3080/3YKZ3080, Vibrating Feeder ZG1220Z/ZSW1360, Twin Screw Sand Washer 2XL1120, Bar Vibrating Feeder ZSW1360B, Bucket Wheel Sand Washing Machine DS4024, dewatering screen TS2450 many types of equipment. They will work together with the whole production line to crush and process the sand trap cobbles and mountain ores into natural sand, mechanism sand, and uniform material.
The finished products of the project are used for high-speed railway construction and neighbouring construction materials, which will strongly promote the local economic development. In the future, Jianye Heavy Industry Company will continue to give full play to its years of practical experience in the sand and gravel aggregate, construction waste resource reuse, industrial powder making, silica sand and other industries, as well as EPC one-stop turnkey services, to cooperate with customers and jointly promote the high-quality, healthy and sustainable development of the sand and gravel industry.
Jiangsu Rugao Calcium Powder Factory purchased two sets of Jianye 4121 high-pressure mills for the production of heavy calcium powder, which is mainly used in the filler industry and coating industry, and now it also maintains a close cooperation relationship with Jianye, and every year Jianye sends technicians or sales managers to visit the user.
The user uses calcined petroleum coke to grind and make powder, and the finished coke powder is mainly used for processing graphite electrodes. In recent years, the price of coke powder rises, the user spends tens of millions of dollars to build a production line with an annual output of 60,000-100,000 tonnes of high-quality coke powder, which is the first phase of the project, using two sets of 6R4528 high-pressure grinding mills of Jianye Company.
