What is the Jaw Crusher?
A jaw crusher breaks hard, brittle material between a fixed and a moving jaw. It is the standard first stage for rock, ore and clinker samples, giving a fairly uniform product with an adjustable gap.
What is the Jaw Crusher?
A jaw crusher breaks hard, brittle material between a fixed and a moving jaw. It is the standard first stage for rock, ore and clinker samples, giving a fairly uniform product with an adjustable gap.
Overview
A jaw crusher consists of a fixed jaw and a moving jaw that oscillates toward and away from it, crushing material caught between them. The eccentric drive and toggle mechanism generate high compressive force, so the crusher handles hard and abrasive feed. The discharge gap can be adjusted to control product size, and the jaw plates are made of hardened or manganese steel for wear resistance. Feed enters from the top and the crushed product falls out the bottom, where it can be collected in a tray. Laboratory versions are bench- or floor-mounted and sized for modest sample masses, and they are the usual choice before a finer mill.
How does it work?
Crushers apply mechanical forces that exceed the strength of the feed material, causing it to fracture. Jaw crushers press material between a fixed and a moving jaw, roll crushers draw it between counter-rotating cylinders, cone crushers squeeze it in a gyrating chamber, hammer crushers strike it with rotating hammers, and impact crushers break it against a rotating or fixed anvil. The reduction ratio, feed size and product size depend on the machine geometry, the gap setting and the material hardness. Crushing is normally the coarse stage that prepares feed for a mill, and over-crushing is avoided because fines can complicate later handling. Wear parts are made from hardened steel or manganese alloys to resist abrasion.
What are the key features?
- High compression force for hard and abrasive material
- Adjustable discharge gap for product size
- Manganese or hardened steel jaw plates
- Robust continuous-duty drive mechanism
- Collection tray for crushed product
What are the technical specifications?
A typical jaw crusher configuration offers max feed size of 100 mm, product size of 1–15 mm, adjustable, throughput of Up to 200 kg/h, jaw plate material of Manganese steel, gap adjustment of Manual or motorised and motor power of 1.5–4 kW. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.
Which applications is it used for?
The Jaw Crusher is used in rock and ore sample preparation, clinker and cement analysis, geological field sample grading and ceramic raw material crushing. Across the wider Crushers class, laboratories also deploy it for mining and ore sample preparation, cement and clinker analysis and geological and soil sample reduction.
Which standards and certifications apply?
Relevant standards and methods include ISO 3310-1, ASTM E11, ISO 2591-1, IEC 61010-1 and ISO 6497. Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.
Install crushers on a firm floor with the necessary electrical protection and, where required, dust extraction and noise enclosure. Do not exceed the rated feed size, since oversized pieces can jam the machine or damage the jaws. Feed material gradually and avoid running the crusher empty for long periods. Check and replace wear parts on schedule, and clean thoroughly between samples to avoid cross-contamination, using a blank or quartz flush where trace analysis demands it. Follow lock-out procedures during maintenance and guard all moving parts.
How do I select the right Jaw Crusher?
Choose a jaw crusher for hard, abrasive feed where a uniform product and adjustable gap are needed. Confirm the maximum feed size matches the largest sample piece and that the product size suits the next milling stage. In an RFQ state the feed size, required product size, throughput, jaw plate material and electrical supply.
How does it compare with other Crushers variants?
Choose a crusher according to the feed size, hardness and abrasiveness of the material and the required product size. Jaw crushers suit hard, brittle lumps and give a fairly uniform product with adjustable gap. Roll crushers suit medium-hard, brittle material and produce less dust. Cone crushers handle high throughput of hard material. Hammer and impact crushers suit softer, less abrasive materials and give higher reduction ratios. Confirm that the feed opening accepts the largest pieces, that the reduction ratio matches the required downstream size, and that the crushing chamber and wear parts suit the abrasiveness. Consider dust control, sample representativeness and cleaning between samples.

Frequently asked questions about Jaw Crusher
Product size is controlled by the discharge gap between the jaws, which can be adjusted on most laboratory models. A smaller gap gives a finer product but reduces throughput and increases wear. The gap is set before processing and checked against the sample method.
Jaw plates are commonly made from manganese steel or hardened alloy steel for wear resistance. For trace analysis where iron contamination matters, ceramic or tungsten carbide plates may be available. The plate material should be chosen to avoid introducing elements being measured.
Laboratory jaw crushers are designed for intermittent or moderate continuous duty, but long runs of abrasive material wear the jaws and raise the temperature. For large sample series, allow cooling periods and monitor wear so that product size stays within specification.
Crushing is the coarse stage that breaks large lumps into smaller pieces, typically down to a few millimetres, using compression or impact. Milling is the finer stage that reduces material to powder, often below one millimetre, using impact, friction or cutting. Crushers protect mills from oversized feed.
A jaw crusher is the usual choice for hard, brittle rock because it applies high compression force and tolerates abrasive material. A cone crusher handles higher throughput of hard material, while roll crushers suit medium-hard brittle samples where less dust is preferred.
Wear parts should be chosen to avoid introducing the elements being analyzed, and the chamber is cleaned or flushed between samples. For trace work, a quartz or other inert flush may be crushed and discarded first. Recording cleaning procedures in the method supports reproducibility.
