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.
A mobile jaw crusher weighs between 15 and 80 tonnes, depending on the model; this factor directly affects its mobility, stability during operation and service life. Selecting the correct weight for the operating conditions helps to improve efficiency and reduce maintenance costs.
Small models for the fine crushing of construction waste weigh between 15 and 30 tonnes, and are convenient for transport between small sites; medium-sized models for processing ore weigh between 30 and 55 tonnes and combine sufficient capacity with relative mobility; heavy-duty industrial models for crushing hard rock weigh between 55 and 80 tonnes and are characterised by high stability during prolonged continuous operation.
Models that are too light tend to vibrate more at high output levels, which accelerates wear on the jaw plates and support components and requires more frequent maintenance; whilst heavier models ensure stability during operation, reduce vibration loads on the mechanisms, and extend the equipment’s service life; however, they require more powerful tractors for transport and are more difficult to move between sites with limited infrastructure.
First, assess how often the crusher will need to be moved between sites; if work is carried out at a single fixed site for an extended period, you may opt for a heavier, high-performance model; if frequent movement between small sites is required, choose light or medium-weight models weighing up to 40 tonnes; also take into account the hardness of the rock being processed; for hard materials, always select heavier models to minimise wear and tear.
