This page explains how Crushing Chamber is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
The enclosed space within a primary crusher where raw materials are initially reduced in size through compression and impact.
Technical details and manufacturing context for Crushing Chamber
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Chamber Width | 600–1500 mm | Determines maximum feed size |
| Chamber Depth | 800–2000 mm | Affects crushing ratio and throughput |
| Feed Opening Size | 500×800–1500×2000 mm | Maximum rock dimension accepted |
| Throughput Capacity | 50–500 t/h | Depends on material hardness and settings |
| Closed Side Setting (CSS) | 50–200 mm | Adjusts product size |
| Eccentric Throw | 10–30 mm | Affects crushing force and capacity |
| Operating Temperature Range | -20–40 °C | Outside this range, lubrication performance degrades |
| Motor Power | 75–250 kW | Matches required crushing force |
| Weight | 10–50 t | Affects foundation and transport |
| Liner Material Hardness | 45–55 HRC | Higher hardness increases wear life |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 250 MPa (36,260 psi) - compressive stress during peak loading |
| other spec: | Feed size: Up to 1.5m (59 inches) typical for primary crushers, Throughput: 500-5000 tph depending on configuration |
| temperature: | Ambient to 150°C (302°F) - limited by lubricants and seals |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

The crushing chamber is the enclosed space in a primary crusher where raw materials are reduced in size through compression and impact. Its design and configuration determine the crusher's capacity, product size distribution, and efficiency.
Common materials include manganese steel and alloy steel. These materials provide high wear resistance and impact toughness. The hardness of the liner material, typically 45-55 HRC, affects wear life.
The CSS is the minimum gap between the moving and fixed surfaces in the crushing chamber. Adjusting the CSS changes the final product size. A smaller CSS produces finer material, while a larger CSS yields coarser output.
Key parameters include chamber width, depth, feed opening size, throughput capacity, CSS, eccentric throw, operating pressure, temperature range, motor power, weight, and liner hardness. Always confirm these values with the manufacturer for your specific application.
