Purchasing a cone crusher for crushed stone requires an analysis of the rock type, throughput and cubicity. Find out what data is required to select the right model.
What to consider when buying a rock crusher: rock properties, required particle sizes, and throughput. A checklist of factors to consider when choosing a crusher, and common mistakes.
Find out when a hammer crusher is suitable for stone and when it isn’t. Key specifications for ordering, laboratory tests, and how to integrate it into the production line. How not to
A bridging event in a jaw crusher is identified by a sudden drop in output, a steady build-up in the hopper, changes in vibration, and a cessation of output, thereby distinguishing it from other faults.
To protect the rotary crusher from reinforcing bars in construction rubble, four sequential methods are used: a vibrating screen, a magnetic separator, hardened rotor hammers, and an inclusion discharge system, all of which have been validated through field trials.
When a jaw crusher is under load, the engine speed often drops because the rated load is exceeded; other causes include wear and tear on transmission components, incorrect material feed settings and low ambient temperature.
In the case of the 92%, a tracked crusher may lose traction in a quarry when the gradient exceeds 18°, caused by reduced track contact, overheating of the hydraulic system and a shift in the centre of mass; the recommended maximum gradient is 16°.
This article explains how to calculate the payback period for a mobile crusher at a seasonal quarry: the formula, the stages of the calculation, standard parameters, influencing factors, and answers to frequently asked questions regarding the data.
When processing shale, the jaw crusher’s throughput falls by 22–31%, whilst wear on the jaw plates increases by a factor of 1.6–2.3. Adjusting the jaw angle reduces this negative effect; however, blockages may occur if the moisture content exceeds 6.2%.
When crushing quartzite, the 28% cone crusher is more economical than a jaw crusher in terms of wear parts consumption, has longer replacement intervals for components and is less sensitive to changes in feed material.
