The integration of a magnetic separator into a reinforced concrete processing line comprises three stages: selecting an installation point downstream of the crushing unit, connecting to a 380V supply, and adjusting the parameters according to the reference ranges, with a metal capture efficiency of at least 98%.
For road projects involving frequent crossings, a mobile line is selected based on four parameters (2024–2025 tests): deployment <45 mins, reinforced frame, site ≥0.2 MPa, additional verification of specifications.
In rotary crushers for limestone and diabase, pairs of hammers are matched by weight to ensure balance. Rearranging them at random increases vibration, accelerates wear and reduces the service life of components by 60–70%.
When processing river pebbles, a rotary crusher produces more cube-shaped grains than a 18%—which are preferable for building materials—whilst a cone crusher suffers less wear; it is possible to use both in combination.
The selection of lining materials for basalt and granite differs in terms of hardness (7–8 versus 8–9 on the Mohs scale), the abrasiveness of the raw material, layer thickness and chemical resistance, due to the differing silicon dioxide content in the rocks.
An engineering approach to selecting a Chinese manufacturer of crushing plants: assessing specifications, logistics, climate and after-sales service. What data is required to make a decision.
When selecting a mobile rotary crusher for reinforced concrete products, please bear in mind the following: 4–6 hammers on the rotor, conveyor speed 0.8–1.2 m/s, weight up to 45 tonnes, maximum feed size 800 × 800 mm.
Evaluate a 120tph tracked mobile crusher for crushed rock, concrete and construction waste. Key specifications, limits and missing data for quarry owners.
The crusher’s annual availability is 82%, with the following factors: scheduled maintenance (9%), breakdowns and organisational issues. The estimated range is 80–85%; adherence to the maintenance schedule reduces unplanned downtime by at least 12%.
Mobile crushers operate for 8,000–12,000 motor hours before their first major overhaul; the interval depends on the material being processed, maintenance, and operating conditions. During the overhaul, the plates, bearings and belt are replaced, and vibration levels and lubricant consumption are monitored.
