The vertical shaft impact crusher (or VSI) has a rotating shaft that runs vertically through the crushing chamber. In a standard configuration, the VSI's shaft is outfitted with wear-resistant shoes that catch and throw the feed stone against anvils that line the outside of the crushing chamber.
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 …
Sampling is a vital part of the crushing process, to ensure that you know the size distribution of the feed. It's crucial that sampling is done regularly, especially when there are changes in blasting, mining or any other upstream processes.

Closed-Side Setting Effect on Feed Size. Measurement of the crusher's closed side setting (CSS) varies depending on the jaw profile that is being used and has an impact on the crusher's capacity and product gradation. Diagram of closed-side setting effect on feed size [image: (135-5-13)]
The feed size to the HPGR in some Brazilian mines is 90% passing 1 mm [3], but the use of coarser feed sizes (16–50 mm) was reported by Patzelt et al. [15]. At Argyle diamonds, (Australia), Maxton [23] reported charging feed size of 80% passing 75 mm with lumps up to 250 mm.

Gyratory crushers are principally used in surface-crushing plants. The gyratory crusher (Figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric sleeve.The spindle is suspended from a "spider" and, as it rotates, normally between 85 and 150 rpm, it sweeps out a conical path within …

crushers take blasted, run-of-mine, or run-of-quarry feed up to 1500 mm and produce a product ranging in size from -300 mm for conveyor transport, or -200 mm for SAG mill feed. The primary can produce these sizes at a rate of …
2. Feed opening "B" is at a minimum setting "A". 3. Maximum feed size vary from 80 to of "B" depending on the machine size and material. Each HP cone crusher has several cavity options with different feed openings and setting ranges. The correct cavity can be selected based on the feed size, setting and application.
Mechanized crushing has existed for 150 years. 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.
Primary crushers can handle large feed lump sizes and typically include Jaw Crushers and Gyratory Crushers, but Impact Crushers may also be used as primary crushers if the material is easily crushed and not abrasive. After the primary crushing stage, further stages of crushing may be required to better control the size of the output …
The maximum feed size varies with each model but is generally limited to 609mm (24") to 914mm (36"). The output gradation of the primary HSI crusher is generally coarser than the primary breaker due to the lack of expansion above the rotor, which also affects the capacity. ... (VSIs) have material fed into the centre of the crusher through ...

Preparing and downsizing the material to the ideal feed size for your small rock crusher is critical to achieve a high production and low operating costs. "Your small rock crusher is the most likely your most expensive piece of equipment and you want to run it as efficiently as possible and as short as possible". (4) The Excavator Reach Matters ...
A jaw crusher, like 2036 in the Jaw Crusher Table here above, would be able to take the maximum 12 in. size quarry stone but it would not have the required 70 tph capacity needed. To have the needed capacity a jaw crusher like the 2042 or 2436 sizes will have to be selected overloading the secondary crusher.
