To choose a suitable industrial jaw crusher for rock, assess the characteristics of the raw material (hardness, moisture content, lump size), the required throughput and the desired final product size; also check the build quality, ease of maintenance and the manufacturer’s after-sales service.
When purchasing a heavy-duty jaw crusher for quartzite, you should choose equipment with jaws made of wear-resistant steel, with a suitable drive power and output size range, and not skimp on the working components. During operation, avoid feeding oversized raw material, ensure all components are properly lubricated and replace worn parts; adhere to the loading specifications and carry out inspections every 200 hours of operation to extend the service life.
When selecting a jaw crusher with a capacity of 250 t/h, three key factors must be taken into account: the characteristics of the material to be processed (select reinforced jaw plates if the raw material is highly abrasive), check the actual throughput under operating conditions, and confirm the availability of local service and spare parts from the supplier.
Hydraulic jaw crusher for crushing hard materials: select based on the size of the feed material, capacity (reserve not exceeding 30%) and the hydraulic system pressure required for the hardness of the rock. Before starting up, calibrate the drive, check for leaks and run the machine idle for 10 minutes. Operate the machine without any non-crushable objects, clean the hopper, check the hydraulics daily, carry out diagnostics monthly, and do not overload the machine.
A jaw crusher with a feed size of up to 700 mm is suitable for the primary crushing of hard rock. When selecting a model, take into account the size of the feed material, the compression force required for the rock’s hardness, and the required throughput. During operation, warm up the mechanism before the first start-up, do not feed in raw material larger than 700 mm, check the jaw plates for wear and tighten the fastenings. Carry out a routine inspection every 30 working hours, clean the crushing chamber and check the bearing lubrication to extend the service life.
A jaw crusher is a piece of industrial equipment; its price ranges from 150,000 to several million roubles, depending on its capacity, the materials used in its components, the availability of additional options, and the type of production. You can distinguish a high-quality machine from a counterfeit by checking the manufacturer’s markings, certificates, smooth welds, smooth operation and the availability of after-sales service. Attractive offers are available from authorised dealers and at industrial trade fairs and exhibitions; it is also possible to purchase tried-and-tested second-hand equipment with a residual warranty.
