The price of a quarry crusher depends on its power, configuration and brand. It is not advisable to buy from intermediaries or overseas suppliers; it is best to order directly from reputable domestic manufacturers, ensuring you clarify which services are included.
Chinese stone crushers are reliable and affordable. When making your choice, take into account the raw materials and production capacity; choose exporters with at least five years’ experience, buy directly, avoid low prices, and don’t forget to consider energy costs.
This publication describes the depreciation cost of equipment when crushing 1,000 tonnes of quartz (2026 – 12.8–17.4 thousand roubles), influencing factors, methods for reducing costs by 18–22%, and recommendations for mining enterprises.
The cost of crushing one tonne of raw material in the mining industry depends on the equipment, the raw material and the operating conditions; it includes energy costs, depreciation and wages, and can be optimised through appropriate operating procedures, maintenance and modernisation of the equipment.
The checklist for transporting a mobile crusher includes preparing the equipment, selecting the trailer and obtaining the necessary permits, loading and securing the equipment correctly, monitoring the journey, and carrying out a post-unloading inspection to ensure the equipment remains in good condition.
The presence of a large fraction of substandard material at the outlet of a cone crusher is a sign of a fault: an incorrect cone clearance, incorrect feed rate, wear and tear on working parts, or malfunctions in the hydraulic control system.
A cyclic load in a closed cycle is a repetitive mechanical load that causes the accumulation of micro-damage and leads to fatigue failure of structures. It arises from periodic changes in the operating modes of systems; it is taken into account during design, assessed using fatigue curves, and its adverse effects are mitigated through the selection of materials, structural optimisation and monitoring.
The crushing of reinforced concrete and magnetic separation — key stages in its processing that yield recycled aggregate and steel reinforcement whilst reducing waste — are being automated and will form the basis of the construction industry’s circular economy.
The primary screen on sorting lines separates the raw material into fractions, increases throughput by 18–25%, is effective when the proportion of fines exceeds 15% in ore, crushed stone or coal, and is easy to maintain.
This article examines how the particle size distribution of the ground product depends on the width of the discharge slots in crushing and grinding equipment, explains the mechanisms behind this influence, and provides practical recommendations on selecting parameters for various production tasks.
