A compact, mobile jaw crusher for quarries is an indispensable piece of equipment, offering the advantages of flexibility, cost-effectiveness and compactness, and enabling the processing of rock of varying hardness without the need for complex installation. When selecting a model, factors such as rock hardness, particle size, daily processing capacity, as well as ease of maintenance and the availability of spare parts are taken into account.

A mobile jaw crusher with a capacity of 300 tonnes per hour — a mobile unit for crushing hard rock, featuring a reinforced jaw assembly; it is suitable for a range of raw materials, site topography and compatibility with other equipment, and reduces logistics and energy costs.

Dust generated during stone crushing is harmful to workers’ health and reduces the service life of equipment. There are simple, cost-effective methods for reducing dust levels: moistening the raw material with water before processing, sealing off the crushing area with wear-resistant material, and installing a local extraction system with a filter.

A stationary jaw crusher requires a robust, correctly designed foundation to ensure stable, long-term operation. The design takes into account the total weight of the crusher, the dynamic load caused by the impact of the jaw plates, and the bearing capacity of the ground. The foundation is laid below the frost line and reinforced with steel bars. Once the concrete has set, the supports are checked for levelness and the concrete is allowed to reach full strength before installation.

A crushing and screening plant with a capacity of 200 t/h is a key component of mining and construction operations; it comprises a hopper, crushers, screens and conveyors. During the design phase, it is essential to test the raw material, allow for a capacity margin of ≥15%, and provide sufficient space for maintenance. Common mistakes include allocating too little space for screens and failing to consider the vibrational compatibility of components.

For processing basalt with a feed size of up to 600 mm, a PE series jaw crusher is ideal: it can withstand the stresses of crushing hard, abrasive raw materials; choose a model with a feed opening of 600 mm or more and reinforced, wear-resistant jaws. It is more cost-effective to buy directly from the manufacturer without intermediaries; this avoids mark-ups and provides free advice and warranty service.

For a mobile crushing plant at a remote quarry, equipment is selected to suit the unstable infrastructure: based on the type of raw material (jaw crushers for hard rock, rotary crushers for soft rock), fitted with a diesel generator, and suitable for transport along dirt tracks. The site is levelled, the ground is compacted, and storage areas are set up. During the initial start-up, the components are checked whilst idling for an hour; consumables are stocked up; and the vibratory plates and belts are inspected once a week — this extends their service life by 30–40%.

To crush concrete whilst separating the reinforcement, you need to select specialist equipment suited to the scale of the work and a reliable contractor. Mobile hydraulic shears are suitable for small sites, whilst stationary systems with a separator are required for industrial-scale projects. Choose contractors with at least three years’ experience, their own equipment and a transparent quotation; this guarantees quality, safety and no unnecessary expenditure.

When crushing hard quartzite, the equipment is selected according to the hardness of the raw material: jaw crushers for the primary stage, cone crushers for the secondary stage; hammer crushers are not suitable. Common mistakes include overestimating throughput capacity, incorrect clearances between components, and neglecting dust extraction. Regular inspection of components, a uniform feed of raw material and scheduled maintenance extend the equipment’s service life by 1.5–2 times.

A turnkey iron ore crushing line saves the client the trouble of coordinating individual stages of the work. Before placing an order, you need to determine the throughput, the size of the final fractions and the characteristics of the raw material; check the contractor’s portfolio; avoid selecting them solely on the basis of a low price; and sign a contract with clear deadlines and a list of works.
