7 Types of rock crushers have different advantages in many aspects like crushing ability, suitable material, lifespan, etc. Once you know what are the differences, you know to choose an optimal crusher.
The rotor of a horizontal shaft impactor is oriented horizontally and utilizes blow bars or hammers to strike flowing material with great force in order to break it. Horizontal shaft impactors are useful as both primary or secondary crushers and are able to crush a wide range of materials, from soft rock to much harder materials.
The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig. 5. It consists essentially of a gyrating crushing head (521) working inside a crushing bowl (522) which is fixed to the …
There are two main types of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers utilize a horizontal rotor that throws the material on stationary anvils or curtains, which results in the material breaking upon impact. VSI crushers, unlike the traditional crushers, have a vertical rotor which ...
The horizontal shaft impactors are the most common impactor type that can be used in recycling, primary and secondary crushing applications. This type impactor will take reasonable size pieces and produce small output material.

In the secondary and subsequent stages, the material is further reduced and refined for proper size and shape, mostly based on specifications. Most secondary crushers are cone crushers and horizontal shaft impacts. For coal, many times, rotary breakers are used as primary crushers and ring granulators are used as secondary crushers.
This article provides a comprehensive guide to primary, secondary, and tertiary crushing. We will delve into each stage of the crushing process, discussing the types of crushers used, their working principles, common applications, and differences between them and other comminution processes. We will also provide answers to frequently …

istance.® NP SeriesTM HSI crushers for primary rangeHorizontal Shaft Impact (HSI) crusher primary range has been designed to increase the cr. shing process …
You need an efficient rock crusher for crushing stones, concrete, gravel, or other materials. Impact crushers use high-speed impact forces instead of compression to crush material. There are key differences between horizontal shaft impact (HSI) and vertical shaft impact (VSI) crushers, and understanding them will help you select the best …
Comprising type of jaw crusher—the robust Single-toggle and the efficient Double-toggle—these hefty machines operate on the principle of compressing materials between a stationary "fixed jaw" and a moving "swing jaw," attached to an eccentric shaft.
Some interparticle crushing (rock on rock crushing) also occurs inside the chamber. They are designed for secondary, tertiary and quaternary crushing of primary crushed ore and aggregates. At Weir, we offer both the live-shaft and fixed-shaft ("pedestal") cone crusher designs to service the diverse needs of our global mining and aggregate ...
The degree to which material is reduced through stages of primary, secondary, and tertiary crushing can depend on the type of material, like aggregate, concrete, and asphalt, and can also depend on the variety of output sizes needing produced. Primary crushing is the first stage of material reduction and can sometimes …
The crushing system with primary gyratory crusher and secondary impact crusher is particularly suitable for compact hard and also abrasive rock. With the preceding coarse reduction, it is possible to use crushing tools made of highly wear-resisting cast-steel in the secondary crusher (austenitic high alloyed cast iron).
Horizontal Shaft Impactors (HSI) are widely used in demolition, aggregate recycling, or operations producing road base material. Superior's Sentry HSI is a rugged and resilient horizontal impact crusher capable of processing large feed sizes from dirtier conditions.
We recently experienced main shaft failure on our crusher. Initial indications are that this is a fatigue creep failure on the top end of the shaft. We are reviewing all critical components and spares as a consequence of the failure and I would like to tap into knowledge base of this forum with a few questions:
Primary crushing – The duty of the primary crusher is, above all, to make it possible to transport material on a conveyor belt. In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used. If material is easily crushed and not excessively abrasive, an impact breaker …
Outotec's line of Superior™ Primary Gyratory crushers are designed to meet the demand for high efficiency and high capacity mining installations. Superior™ MKIII is the first high speed Gyratory. The new features allow significant CAPEX reduction of a primary crushing stage from the retaining wall to the primary stock pile.
The all-new 700 series of Horizontal Shaft impact crushers offers new levels of safety and efficiency. Developed to comply with new EU legislation, you can configure these smart, modular crushers to operate in a variety of applications in either primary or secondary crushing mode. The perfect HSI crusher for primary (feed sizes up to ...
The primary stage was once viewed merely as a means to further reduce stone following the blast or excavation – prior to secondary crushing. Today, primary crushing is viewed as more important within the balance of production and proper sizing needs. The size and type of the primary crusher should be coordinated with the type of …
Learn what a primary crusher is and why it is important for your crushing business. Discover the types of primary crushers to increase crushing efficiency.
Primary crushers reduce large run-of-mine material, such as rocks and ore lumps, into smaller sizes for further processing downstream, whether that be transport to additional crushers or to a wet processing plant. It is the first stage in the crushing process that can sometimes include …
The primary impact crusher is a solid performer since its ground-breaking introduction. The Stedman Mega-Slam horizontal impactor effectively handles large feed sizes - …
Discover how does a jaw crusher work with our simple guide. Learn about the mechanics and operation of jaw crushers on our blog.
Due to the use of a hydraulic main shaft support mechanism, the GY primary gyratory crusher can be started under full load should it be required; e.g., in the case of an unplanned power failure.
The function of the primary crusher is to break down the larger rocks and stones into manageable sizes, while the function of the secondary crusher is to further refine these sizes into the desired product. The secondary crusher operates by compressing the material between two surfaces, similar to the primary crusher.
Operating a gyratory crusher within its design parameters reaps huge benefits for the end-user, most notably, maximum crusher online availability, lowest possible maintenance repair costs, improved productivity and maximized crusher life span.
