Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".

A large primary crusher is, naturally, more expensive than a smaller one. Therefore, the investment cost calculations for primary crushers are compared together against the total costs of primary stages, including quarry face clearing, blasting, and drilling costs. In many cases, dump trucks transport the rock to a stationary primary crusher.
— There are five crushers consisting of primary crusher, secondary crusher, tertiary crusher, and two crawler crushers at this crushing facility. The ore coming from the quarry is passed from the grid with a clearance of 150 mm and the material above a grain size of 150 mm are conveyed to jaw crusher with a capacity of 400 tonne/h.

Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing
— How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. …
— For secondary and tertiary crushing, an impact crusher is most often used. HSI crushers can work in both the primary and secondary stages, while VSI crushers are primarily used towards the end of the crushing process as a tertiary crusher. Finding The Right Impact Crusher For Your Project's Needs. When choosing a crusher, it is …
— The primary crusher reduces the size of the raw material and prepares it for the secondary crushing stage, while the secondary crusher further reduces the material size and shapes the final...
— There are some distinct differences between HSI and VSI impact rock crushers regarding how they operate, maintenance requirements, production efficiency, final product shape, and the types of materials they work best on. Impact Force Direction. The primary difference between HSI and VSI crushers comes down to the direction from …
Primary jaw crusher and secondary impact crusher working together in a plant set-up. The most common primary crusher is a jaw crusher, but, there are many other types including gyratory and cone crushers. We will talk about them all in more detail later! ... There are different kinds of primary crushers for all different use cases. No matter ...
The fundamental differences between primary and secondary data are discussed in the following points: The term primary data refers to the data originated by the researcher for the first time. Secondary data is the already existing data, collected by the investigator agencies and organisations earlier.
— Despite the fine differences between the equipment, at the end, they all have the same objective: to reduce the size of rocks - and, of course, to supply the market with products as varied as gravel for construction or iron ore for the steel sector. ... Horizontal shaft impact crushers are used in primary, secondary or tertiary crushing …
Crushers have been around since ancient times and have undergone various changes over the years. Among the biggest changes is the difference between primary and secondary crushers. In this article, we'll discuss the key differences between primary and secondary crushers. First, let's define what these terms mean.

The most common type of cone crusher is the cone crusher, which has been designed for use in secondary or tertiary crushing applications. The main difference between the two is that a cone crusher is designed to crush hard rocks and ores, while an impact crusher is more commonly used for softer materials such as limestone.
— With the design differences also comes cost differences. The Double Roll Crusher is the more cost-effective option of the two. The main differences that make up the majority of the cost differences is the drive configurations. Since the Double Roll Crusher is V-belt driven, lower motor horsepower can be used due to the flywheel design.
Where the material is not reduced sufficiently in the primary crusher, it is then crushed by a secondary crusher to achieve the correct size of the material. Wear on parts of the crushers affect the performance and volume of material being crushed, the parts subject to high impact, and abrasive wear include the hammers, rotors, teeth, and mantles.
— The three main types of primary crushers are jaw crushers, gyratory crushers, and hammer crushers. Jaw Crusher Jaw crushers use the compressive and bending action of a fixed jaw plate and a movable jaw plate to crush materials of various hardnesses.
