When selecting a mobile jaw crusher with a Cummins engine, three factors must be taken into account: match the power output to the type of material being processed, ensuring that the machine is not overloaded; choose a model suited to the region’s climate (heating for cold weather, a larger radiator for hot weather); check the availability of servicing and spare parts at the site of operation.
When selecting a mobile jaw crusher fitted with a Cummins engine, it is necessary to assess the compatibility of the power unit with the crushing parameters, operating conditions and service life, in order to obtain reliable equipment for processing rock and construction waste without unnecessary maintenance costs.
Cummins engines come in a range of power ratings; select the appropriate rating based on the maximum size of the feed material and the daily workload: units from 120 kW are suitable for processing soft limestone, whilst versions from 250 kW are required for hard granite. Do not allow the engine to operate continuously at maximum load, as this reduces its service life by 40%.
Cummins models offer varying degrees of protection against low and high temperatures: for operation in regions where temperatures fall below -20 ℃ , choose versions with a pre-start heater and a reinforced battery pack; for hot regions where temperatures exceed +35 ℃, ensure an enlarged cooling radiator is fitted; this will prevent unscheduled equipment shutdowns during peak operating hours.
Before purchasing, please check whether there are any authorised Cummins service centres in the region where the crusher will be operated, as well as whether standard consumable parts – such as filters, belts and injectors – are in stock. Genuine spare parts for this brand’s engines have a proven service life, and a lack of availability can result in equipment downtime of up to 7 days should a fault occur.
