In the mining, building materials, metallurgy and other industries, crushing equipment is an indispensable and important tool. With the continuous advancement of technology, the types of crushers are becoming more and more abundant. Among them, hammer crusher (small hammer crusher) and heavy hammer crusher (heavy hammer crusher) are two common crushing equipment, each with unique characteristics and advantages. This article will discuss the difference between heavy hammer crusher and hammer crusher in detail from multiple aspects, so that readers can make more appropriate decisions when choosing.
1. Appearance and size
First of all, there are obvious differences between heavy hammer crusher and hammer crusher in terms of appearance and size. Hammer crusher, that is, small hammer crusher, is usually small in overall size, whistle-like, and compact in size. For example, the appearance parameters of a certain model of hammer crusher may be 1800x1590x1775mm, which is suitable for use in occasions with limited space. The heavy hammer crusher, that is, the heavy hammer crusher, has a relatively large size. For example, the PCZ1615 heavy hammer crusher has an appearance parameter of 3371×2925×2752mm. This large size design enables the heavy hammer crusher to accommodate a larger crushing chamber and a heavier hammer head, thereby improving its processing capacity and crushing efficiency.
2. Production capacity
Production capacity is one of the important indicators to distinguish between heavy hammer crusher and hammer crusher. Due to its size and power limitations, the production capacity of hammer crusher is relatively small, generally between 3-55t/h, suitable for small production lines or occasions with low production requirements. The heavy hammer crusher is known for its powerful crushing capacity and high output, and can easily meet the needs of medium and large production lines. Its crushing chamber space is large, and the material can rebound and hit multiple times during the crushing process, thereby improving the crushing efficiency and the quality of the finished particle shape.
3. Crushing effect and scope of application
In terms of crushing effect and scope of application, there are also certain differences between heavy hammer crusher and hammer crusher. Hammer crusher is suitable for crushing various medium-hard and weakly abrasive materials, such as coal, salt, chalk, gypsum, etc. It has a simple structure, a large crushing ratio, and high production efficiency, which can meet general crushing needs. However, for ores with too high hardness, such as river pebbles, basalt, granite, etc., the crushing effect of hammer crusher may be affected, and the wear of hammer head will also be aggravated. In contrast, heavy hammer crusher is more suitable for crushing these materials with too high hardness. Its hammer head is heavy and has stronger crushing force, which can crush more materials per unit time while reducing the wear of hammer head.
4. Operating cost and supporting power
In terms of operating cost and supporting power, heavy hammer crusher also has certain advantages over hammer crusher. The operating cost of heavy hammer crusher is low, and the system supporting power is small, which can significantly reduce the production cost. This is mainly due to its efficient crushing capacity and low energy consumption. Although the initial investment of hammer crusher may be low, its operating cost may be relatively high during long-term operation due to the limitation of output and crushing efficiency.
5. Structural features and working principles
In terms of structural features and working principles, heavy hammer crusher and hammer crusher also have similarities. Both equipment are mainly composed of rotor, impact plate, casing and other parts. The motor drives the rotor to rotate at high speed in the crushing chamber. After the material enters the crushing chamber from the upper feed port, it is crushed by the impact, impact, shearing and grinding of the high-speed moving hammer. However, the crushing chamber space of the heavy hammer crusher is larger and the hammer head is heavier, so it can generate greater crushing force and more crushing times during the crushing process, thereby improving the crushing efficiency and the quality of the finished product.
