Jaw crusher model number naming rule popular science

1. Core Naming Logic

Jaw crusher model codes are composed of series code + crushing chamber type + feed opening dimension (width × depth). Different manufacturers follow industry universal naming conventions (especially Chinese mining machinery standards like SBM, Liming, etc.), with minor brand-specific variations.

2. Common Series Prefix Code Definition

PE Series — Primary coarse jaw crusher

  • PE: Primary Jaw Crusher (P=Crusher, E=Jaw; standard coarse crushing model)
  • Typical: PE 600×900
    • Feed opening: 600mm width × 900mm depth
    • Application: Primary coarse crushing, hard rock, mine primary crushing

PEW Series — European fine jaw crusher / Deep-chamber jaw crusher

  • PEW: European Version Jaw Crusher (W=Wide/deep cavity, optimized European structure)
  • Typical: PEW 860×1100
  • Features: Higher swing stroke, deep crushing cavity, finer finished product, used for medium & fine crushing, secondary crushing

PEV Series — Vibrating jaw / New heavy-duty jaw crusher

  • PEV: New heavy-duty jaw crusher, optimized vibration reduction and cavity shape, large mining heavy-duty primary crushing

JC Series — European standard jaw crusher (International brand naming habit)

  • JC = Jaw Crusher, widely adopted by overseas brands
  • Example: JC 1000×1200

Small/Lab Jaw Crusher

  • PE 150×250, PE 200×300: Mini small jaw crushers for quarry small production line or laboratory sample crushing

3. Model Parameter Explanation (Most Critical Rule)

Format: Prefix Code + Feed Width × Feed Depth
PE 750×1060
  1. 750 = Feed opening width (mm) (horizontal dimension)
  2. 1060 = Feed opening depth (mm) (vertical dimension)

✅ Rule: The maximum feeding size is generally 80%–85% of feed width.

Example PE600×900: Max feed size around 480–510 mm.

4. Suffix Additional Codes (Manufacturer Customized)

Some manufacturers add suffix letters to indicate special configuration:
  • S: Spring buffer enhanced version
  • H: Hydraulic discharge adjustment
  • M: Mobile mounted (matched with mobile crushing station)
  • T: Track-mounted type
  • Z: Heavy-duty reinforced frame

5. Single Toggle vs Double Toggle Mark

Modern mainstream industrial models (PE/PEW/JC) are single-toggle jaw crusher.

Double toggle jaw crushers rarely use independent prefix codes; manufacturers usually mark it in product introduction rather than model number.

6. Mobile Jaw Crusher Combined Naming Rule

When matched with mobile chassis, the complete model combines chassis + host model:
  • Wheel mobile: YG938E69 → YG=Wheeled mobile station; 938=feeder model; E69=PE600×900 jaw host
  • Track mobile: LT106 → LT=Track mobile; 106 represents 1000×600 jaw crusher

7. Common Misunderstandings

  1. ❌ The two figures are NOT length and discharge opening; they are feed opening dimensions
  2. ❌ PEW is not “small crusher”; it is European optimized cavity, can be large size for medium crushing
  3. ❌ Different brands may use identical model codes but slightly different actual parameters; always check official datasheet
