500 t/h crushers are required for large-scale projects; they are selected based on the raw material, particle size and site conditions, purchased from certified manufacturers with at least 10 years’ experience, and maintained in accordance with maintenance schedules to extend their service life.
A crusher with a capacity of 500 tonnes per hour is a highly sought-after piece of equipment for large-scale mining and construction sites; choosing the right model and a reliable supplier directly determines the stability of the production process and the economic efficiency of the enterprise. When making your selection, you should take into account the type of raw material to be processed, the required output particle size and the specific characteristics of the production site; it is best to purchase from certified manufacturers with at least 10 years’ experience in the industry.
For this level of throughput, jaw, cone or rotary crushers are most commonly chosen. Jaw crushers are suitable for the primary crushing of hard rocks with a tensile strength of up to 350 MPa, cone crushers are ideal for secondary and tertiary processing of medium-hard and hard materials, whilst rotary crushers deliver the best results when crushing soft and medium-hard rocks, producing a cuboid-shaped output fraction.
The first consideration is ensuring that the type of equipment is suited to the characteristics of the raw material; you should not buy a cone crusher for processing limestone, just as you should not choose a jaw crusher for producing fine-grained material. The second important point is that the stated capacity should match actual operating conditions; take into account the moisture content of the raw material and the size of the feed pieces to avoid a drop in capacity during operation. The third criterion is that the drive must have a power reserve of at least 15 per cent for operation under a constant load.
Give preference to local manufacturers with their own production facilities and a spare parts warehouse within your region; this guarantees prompt after-sales support and the supply of spare parts in the event of a breakdown. Be sure to insist on an official warranty of at least two years, as well as the opportunity to carry out a trial crushing of your raw materials on similar equipment before purchasing. Avoid offers from dubious intermediaries with significantly reduced prices; more often than not, this equipment has been refurbished and has a remaining service life of no more than 30 per cent.
Immediately after installation, carry out a full calibration of the crusher components in the presence of a manufacturer’s representative, and train the maintenance staff in the procedures for scheduled maintenance. Inspect wear parts every 200 hours of operation and replace linings in good time to prevent damage to the main components of the equipment. Adhering to these simple maintenance rules will extend the crusher’s service life by 40 per cent without any loss of the specified capacity.
