Mobile Jaw Crusher or Hammer Crusher? A Practical Review of the Supplied Crushing Line

Jaw versus hammer: choose the process first

The supplied graphics advertise “1–50 t/h” on a hammer-line image, a 1–40 mm adjustable discharge range on a separate jaw graphic, and dimensions of 6,700 × 1,400 × 2,700 mm on one illustrated hammer setup. Those figures belong to different promotional images. They are not a common specification for the full gallery or proof of performance on your rock. Ask for a model-specific test and gradation curve using representative feed.

What a complete line should include

The line diagrams show a feed hopper or vibrating feeder, crusher, discharge conveyor, power package, control box and mobile chassis. A complete working installation may additionally need a screen, magnets for reinforced demolition material, dust suppression, guarding, walkways, emergency stops and a safe means of clearing blockages. A wheeled chassis makes relocation possible after preparation; it does not establish road legality, towing equipment or permission to travel under its own power.

Request an equipment schedule that identifies every included component, motor, engine, belt, control panel, guards, tools and wear-part kit. Ask for drawings of the transport and operating footprint, support points and service access. The photograph alone cannot tell you the electrical supply, generator size or whether a loader is required to feed it.

Watch the supplied crusher video

Ask the seller for an uncut test of the exact quoted unit on material similar to yours, with the feed and product size, runtime and measured tonnes documented. A short promotional clip is a useful visual, but not a capacity trial.

Safety, dust and operating cost cannot be afterthoughts

Crushers combine nip points, moving belts, flywheels, stored energy, flying fragments, noise and potentially hazardous dust. Keep people away from feed and discharge zones; fit and maintain guards, emergency stops and safe access. Blockages require a planned isolation and clearing procedure, not reaching into a running machine. The UK's HSE mobile jaw-crusher guidance ↗ covers these risks, including blockage removal and guards. Crushing concrete, brick and silica-bearing stone can create respirable crystalline silica; plan suitable suppression or extraction, exposure assessment and respiratory protection as required by your site and local law.

Include fuel or electricity, wear liners and jaws or hammers, belts, bearings, lubricants, dust controls, operator training, loader time, maintenance downtime and transport in your cost model. Ask for a spare-parts list and lead times. If the supplier claims certification, request documents tied to the actual model and serial number rather than relying on a collage of company certificates.

Before paying on AliExpress

Confirm whether the displayed amount is for a complete machine, deposit, bare crusher, conveyor or a chosen variant. Request a pro-forma invoice naming the crusher type and model, feed opening, motor or engine, rated power, feeder and conveyor scope, guards, output setting, accessories, warranty, wear parts and support. Confirm packaging, freight terms, taxes, duties, arrival handling and commissioning at your site. For imported heavy machinery, ask for a dispatch inspection with serial-numbered photos and test video.

Question to send the seller: “Please specify the exact crusher and included line components, provide a technical drawing, safety and electrical documents, and show a measured test on my feed material at the output size I need, plus a full delivered quote.”

Review basis

Reviewed 27 September 2026 from seven supplied promotional images and one supplied small-jaw video, with HSE guidance on mobile jaw crushers ↗. The gallery depicts multiple machine types and drive options, and the AliExpress short URL could not be independently loaded. Confirm current specification, performance and pricing with the seller before buying.
