Working Principle
SE-J650D modular mini jaw crusher operates on a mechanical compression principle. Material enters the crushing chamber through the feed opening, where it is gripped and pressed between a fixed jaw plate and a moving jaw plate. Driven by an integrated motor and transmission system, the moving jaw follows a precise elliptical motion, applying repeated compressive forces to reduce the size of the input material.
As the material breaks down into smaller particles, SE-J650D gradually moves downward through the chamber until it reaches a size that allows it to pass through the adjustable discharge opening at the bottom. This controlled crushing process ensures consistent output size and minimizes over-crushing, making the SE-J650D both efficient and reliable for light-duty crushing operations.
Application
SE-J650D is ideally suited for lightweight crushing tasks such as jobsite processing, small-scale aggregate production, and handling leftover materials in mining operations. Its compact structure and ease of maintenance make it especially practical for sites with space limitations, minimal foundation preparation, or urgent deployment requirements—such as rural building demolition, school renovations, and pipeline excavation backfilling.
In addition, thanks to its modular design, SE-J650D can be flexibly paired with various conveying or screening units to form a compact integrated crushing system, offering scalable solutions for diverse operational needs.

FAQ
Q1: What is the SE-J650D modular mini jaw crusher best suited for?
A1: The SE-J650D is ideal for small to medium-scale stationary crushing operations. With a capacity of 50-130 TPH and a compact modular design (16.3t total weight), it is perfect for small quarries, rural construction projects, and fixed crushing plants where space is limited. Its plug-and-play modular structure enables quick installation without extensive foundation work.
Q2: What is the maximum feed size for the SE-J650D?
A2: The SE-J650D accepts feed sizes up to 500mm with a 500×700mm jaw inlet. The discharge particle size range is 0-100mm, adjustable to match your specific requirements. This makes it versatile for both primary crushing and producing finished aggregate in a single pass.
Q3: How does the SE-J650D differ from the SE-650D mobile jaw crusher?
A3: The SE-J650D is the stationary/modular version, designed for fixed installation in crushing plants. It weighs only 16.3t (vs 30t for the mobile SE-650D) and does not include a track chassis, feeder, or conveyor system — those components are added separately as needed. The SE-650D is a complete self-contained tracked unit for mobile operations.
Q4: What materials can the SE-J650D handle?
A4: The SE-J650D can crush hard rock (granite, basalt, andesite, river pebbles, iron ore, copper ore), soft rock (limestone, bluestone, dolomite, coal), and construction waste. Its 75kW jaw crusher with high-manganese steel plates ensures effective crushing across all material types.
Q5: How is the SE-J650D installed?
A5: The SE-J650D features a modular design that allows quick assembly on a simple concrete foundation. Core components are pre-assembled and can be connected with standard bolts, significantly reducing installation time compared to traditional fixed crushers. Our engineers can also provide on-site installation guidance and operator training.
