# Capacity, Size, and Power of Jaw Crushers and Cone Crushers

## Introduction
Jaw crushers and cone crushers are two of the most commonly used primary and secondary crushing machines in the mining and aggregate industries. Each has distinct characteristics in terms of capacity, size, power requirements, and application suitability. Understanding these differences helps in selecting the right crusher for specific operational needs.

## Jaw Crusher

Capacity
- Jaw crushers typically handle large feed sizes (up to 1,500 mm) with capacities ranging from 50 to 1,600 tons per hour (tph) depending on the model and settings.
- Their throughput is influenced by factors such as:
- Feed size distribution
- Material hardness (compressive strength)
- Closed-side setting (CSS) adjustment

Size
- Jaw crushers are robust machines with a fixed jaw and a moving jaw that applies compressive force.
- Common sizes range from small laboratory-scale units (e.g., 200 x 100 mm) to large industrial models (e.g., 1,500 x 2,000 mm).

Power Requirements
- Motor power typically ranges from 30 kW to over 300 kW, depending on the crusher size and material hardness.
- Higher power is needed for harder materials like granite or basalt compared to softer materials like limestone.

## Cone Crusher

Capacity
- Cone crushers are primarily used for secondary or tertiary crushing with capacities ranging from 50 to over 2,000 tph.
- Their efficiency depends on:
- Chamber type (standard, short head)
- Eccentric throw setting
- Feed gradation and material properties

Size
- Cone crushers have a conical-shaped crushing chamber with a rotating mantle inside a concave bowl.
- Common models range from small units (e.g., HP100) to large-scale machines (e.g., HP800).

Power Requirements
- Motor power varies widely based on design but generally ranges from 75 kW to over 900 kW. High-performance cone crushers require more power due to finer crushing settings.
