JAW CRUSHERS. YOUR BEST VALUE IN PRIMARY CRUSHING. Heavy-duty, oversized heat treated shafts forged of special alloy to handle overloads and hard material. Radial thrust tapered roller bearings, the best design for absorbing and withstanding shock, radial and thrust loads.

The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers

 — Crusher Efficiency Calculations. Crushing & Screening Plant Assessment Example. The following example demonstrates a method of selecting the components of an aggregate plant. Good component efficiency and part performance pre-evaluation is essential to a solid design. The aggregate production requires the consideration of …

We are the world's leading supplier of both unit machines and complete aggregates processing systems. Comprehensive process solutions Your system may involve a whole series of proc-

operating the crusher in closed circuit, the total crusher load needs to be used in calculations (raw feed plus return feed). In capacity tables the minimum and maximum recommended throughputs for each crusher range with normal

 — Calculate Crusher MOTOR HORSEPOWER. Crushing horsepower required is dependent on the hardness and toughness of the material, the ratio of reduction, product size, and the specific gravity. The following method of approximating horsepower requirements may be used as a guide to proper motor selection and power cost estimation:

 — One of the most critical factors in cone crusher selection is the throughput capacity you need for your production objectives. Specify the metric tons per hour you need to produce and choose a crusher sized for that capacity. Undersized crushers will limit throughput, while oversized units are more expensive upfront.

Crushing Efficiency = (Output (TPH) / Input (HP)) * 100. This crushing efficiency formula is an effective tool for understanding what is crushing efficiency and how to calculate it. Here, TPH represents the tons per hour of the material that is outputted from the crusher, and HP means the horsepower used by the crusher.

Rule 1: Always use a jaw crusher if you can due to lower costs. Rule 2: For low capacity applications, use jaw crusher and hydraulic hammer for oversize. Rule 3: For high capacities, use jaw crusher with big intake openings. Rule 4: For very high capacities, use gyratory crusher.

 — The numerator is calculating the volume of one swing of a jaw, times the density of material in the chamber, times the number of cycles per minute. This should give you the mass of material crushed per minute. The denominator looks wrong; to convert to mass per hour should be multiplying by 60, not dividing by 60.
