At temperatures of -20 to -30°C, the mobile crusher operates reliably provided the following guidelines are followed: pre-start-up preparation, correct start-up, gradual feeding without overloading, regular monitoring and maintenance between shifts.
The service life of crusher hammers and liners depends on the raw material, operating conditions and maintenance; typical service life is 3–6 months for hammers and 6–12 months for liners. Proper care and monitoring extend their service life, reducing costs by 25–30% and increasing productivity.
The SF-580D-S model has an actual throughput of 150–350 tonnes per hour, is suitable for a variety of raw materials, operates reliably, with deviations from specified parameters not exceeding 5%, and its wide operating range simplifies production planning.
The SF-380D-2S power unit passed an 8-hour test under standard conditions: stable operation, no failures, fuel consumption is 4% lower than analogs, suitable for intensive use.

Mobile Jaw Crusher needs regular care to prevent breakage and prolong service life: monitor the condition of jaw plates, clean the housing, check the lubrication, fastening units, hydraulics and electrics. Scheduled diagnostics-every 100-150 hours (80 hours with intensive work), unscheduled-with noise, vibration or a drop in performance.
To ensure the stable and safe operation of a mobile jaw crusher and to extend its service life, the following rules must be observed: check the safety guards before starting up, prevent metal from entering the crushing chamber, and stop the machine immediately if any unusual noises are heard; adjust the jaw clearance, the shaft speed to suit the feed material and the feed rate; clean the crushing chamber regularly, check the wear on the jaws, change the lubricant and monitor fluid levels.
You should only look for the latest technical specifications for a mobile jaw crusher from official manufacturers, their dealers or in your personal accounts on corporate websites, rather than consulting random sources. When reviewing the document, pay attention to the capacity, particle size, degree of crushing, safety specifications and maintenance recommendations.
A mobile jaw crusher consumes 12–45 litres of fuel per hour, depending on its power output, the density of the raw material and operating conditions. Irregular maintenance increases fuel consumption by 20–30%. Sorting the raw material, avoiding prolonged idling and carrying out maintenance on time all help to save fuel.
The weight of a mobile jaw crusher ranges from 15 to 80 tonnes, depending on the model, and affects its mobility, stability and service life. They are categorised by weight as small (15–30 tonnes, for construction waste), medium (30–55 tonnes, for ores) and heavy (55–80 tonnes, for hard rock). When making your selection, take into account the frequency of relocation and the hardness of the materials to be processed.
