Choosing a jaw crusher that suits your needs requires careful consideration of many aspects, among which jaw crusher size and production capacity are quite important. Different jaw crusher sizes and different production capacities determine the price and other aspects of the crusher. When choosing a universal jaw crusher, you should consider the purpose of using the crusher, whether it is mining machinery, construction purposes, or domestic waste. The following are several aspects that are often considered when choosing a jaw crusher. I hope it will help customers choose the right jaw crusher.
Factors affecting how to choose jaw crusher
Jaw crusher capacity
Determine the jaw crusher production scale: First, you must clarify your jaw crusher production capacity, that is, how much material needs to be crushed per hour or day. If it is a small stone processing plant like limestone calcination plant with low output requirements, such as processing 1-10 tons of materials per hour, a smaller jaw crusher such as AGPE 150×250 or AGPE 200×300 may be sufficient to meet the needs, while for large mines or large building stone production enterprises, which need to process hundreds or even thousands of tons of materials per hour, it is necessary to consider AGPEX 900×1200 or larger CJ series jaw crushers.
Consider the continuity of production: If the production is continuous and the output stability requirements are high, then when choosing a universal jaw crusher, it is necessary to properly consider that the crusher has a certain capacity margin. Because in the actual production process, the jaw crusher may cause a decrease in production efficiency due to various factors (such as changes in material hardness, equipment wear, etc.), reserving a certain jaw crusher capacity space can ensure that the overall production plan is not greatly affected. What’s more, considering what size of material will be fed into the crusher or what the jaw crusher size is also important. Make sure the crusher has the ability to handle the required material size.
Raw material characteristics
- Material hardness: Materials of different hardness have different degrees of wear on the crushing parts of the jaw crusher. For materials with higher hardness (such as granite, quartz, etc.), it is necessary to select a jaw crusher with a stronger crushing chamber structure and greater crushing force, and the easily worn parts of the crusher (such as the jaw plate) should be made of high-hardness, high-wear-resistant materials. Generally speaking, the larger jaw crusher has a greater advantage in structural strength when processing high-hardness materials.
- Material humidity: If the material humidity is high, it is easy to cause material adhesion, affecting the crushing effect and the normal operation of the jaw crusher. In this case, it is necessary to select a jaw crusher with good discharge performance and an anti-blocking design. Some new jaw crushers have improved the design of the discharge port and crushing chamber, which can effectively prevent the blockage of wet materials.
- Material particle size: The maximum particle size of the feed determines the size of the feed port of the jaw crusher. If the feed particle size is large, it is necessary to select a model with a large enough feed port size. For example, for large pieces of raw stone mined directly from the mine, the maximum particle size may reach about 1 meter, so it is necessary to choose a large jaw crusher with a feed port size of 1500×1300mm, such as CJ150 for coarse crushing, the discharge particle size requirement affects the adjustment range of the discharge port. For the situation where the product particle size is required to be finer, it is necessary to choose a jaw crusher size with a narrow adjustment range of the discharge port and precise control.
Site and installation conditions
Site space size: Consider the site area and spatial layout of the factory or mine. If the site space is limited, it is necessary to choose a model with a smaller jaw crusher size and compact structure to avoid overcrowding after the crusher is installed, which affects the installation and operation of other supporting equipment.
Installation foundation requirements: Different models of jaw crushers have different requirements for the installation foundation. Large jaw crushers require a stronger and thicker concrete foundation to ensure the stability of the equipment due to their own heavy weight and strong vibration, while small jaw crushers have relatively low requirements for the installation foundation. When choosing a universal jaw crusher, consider the difficulty and cost of equipment installation based on the geological conditions of the site and the existing infrastructure.
Cost budget of the jaw crusher
The prices of jaw crushers of different models and brands vary greatly. Generally speaking, large and high-performance jaw crushers are relatively expensive. In the case of a limited budget, it is necessary to comprehensively consider the performance and price of the crusher. For example, the AGPE series jaw crusher is relatively traditional and the price may be relatively affordable, while some European or German jaw crushers with advanced technology may be expensive, but they may have advantages in production efficiency, product quality, and service life.
Operation and maintenance costs: The operation costs mainly include energy consumption and the replacement costs of easily worn parts. Large crushers usually have high power and high energy consumption, but if their production efficiency is also high, the output per unit of energy consumption may be more advantageous. The price and service life of easily worn parts (such as jaw plates, bearings, etc.) also vary in different jaw crusher models. Although the initial purchase cost may be higher when choosing easily worn parts with good quality and long service life, it can reduce the maintenance cost and downtime of the equipment in the long run.
Environmental protection requirements
Dust and noise control: In some areas with high environmental protection requirements, the dust and noise emissions of jaw crushers need to be considered. New jaw crushers are designed with better sealing devices to reduce dust spillage and noise by optimizing equipment structure and using shock-absorbing materials. For example, some European jaw crushers perform better in environmental performance and can meet strict environmental standards.
In addition, when choosing a suitable crusher, you should also consider what power source is available, whether you need an electric or diesel-powered machine, whether the crusher is easy to repair, and whether the selected crusher manufacturer is reliable, so customers must consider all factors when choosing the suitable jaw crushers.
