release on the comparison between Jaw Crusher and Gyratory CrusherIn the field of crushing, the size of the rocks or ore grains is gradually reduced by a method of mechanical force, also known as comminution or crushing. In this process, two common types of crushers – Jaw Crusher and Gyratory Crusher – are commonly utilized. While both these machines are widely used, they have distinct differences and are suited to different applications.Jaw Crusher, also known as a toggle crusher, uses mechanical pressure to break down pieces of rock. It is installed between two heavy plates to receive rock fragmentation in its inlet; the movable plate moves to close against the fixed plate, forcing the rock to compress. This method of comminution is suitable for materials that are soft, brittle or tough. The friability of the rock should be taken into account when selecting this type of crusher. Jaw Crushers are also ideal for crushing hard and abrasive materials like granite, ores, quartz and various rocks, and are often utilized in the production of train track ballast and construction materials.Gyratory Crusher, on the other hand, uses a conical crushing head that remains in a fixed position called a mantle, while the lower part of the gyratory crusher mantle is directly suspended on the eccentric drive shaft. The crushing process starts from the top of the chamber, where a large hopper distributes the rock material evenly between the gyratory cone and the concave. This makes Gyratory Crushers suitable for crushing large and hard materials where a higher degree of reduction is necessary. Gyratory Crushers are commonly utilized in mining and aggregate processing applications.When comparing Jaw Crushers and Gyratory Crushers, several factors must be taken into account, such as capacity, power consumption, materials processed, and productivity. Jaw Crushers are typically specified by the dimensions of the top opening where material enters; typically, this can range from 20 cm to 200 cm. Gyratory Crushers, on the other hand, have a concave surface with a cone in the center placed on a higher position and smaller openings at the bottom. The mantle is located above the concave surface, providing an incoming feed chamber into which the larger rock materials are broken. The capacity of Gyratory Crushers is usually given as a specific tonnage discharge per hour, which can range from 75 to 2,000 ton/h.Another factor to consider is power consumption; Jaw Crushers require less horsepower than Gyratory Crushers. However, high horsepower Gyratory Crushers are utilized in heavy-duty crushing work such as mining mainly because they take advantage of the large feed opening. Selection of both Jaw Crushers and Gyratory Crushers is also influenced by the feed rate, required product size, and the feed characteristics such as gradation, bulk density, moisture, and clay content.In terms of productivity, both Jaw Crushers and Gyratory Crushers excel when it comes to reducing large rocks. However, there are some differences between the two. Jaw Crushers usually have a 6:1 reduction ratio, while Gyratory Crushers can achieve ratios of 8:1. When comparing feed sizes, Jaw Crushers can accept larger sizes than Gyratory Crushers. In addition, Gyratory Crushers are capable of handling high tonnage rates, while Jaw Crushers can be good for small to mid-sized operations.In conclusion, Jaw Crushers and Gyratory Crushers are both effective ways to break down materials for comminution or crushing. While they have distinct differences, both crushers are useful for different applications. Jaw Crushers are well suited for softer materials, while Gyratory Crushers are ideal for large and hard materials that require a higher degree of reduction. Whether you select a Jaw Crusher or a Gyratory Crusher, both types of crushers can efficiently and effectively break down materials to render them ready for processing.
