In other word, 3S consisted of an additional jaw crusher compared to 2S crushing. Likewise, 4S crushing had primary, secondary, tertiary and quaternary crushers as Jaw, Jaw, HSI and VSI (vertical shaft impactor), respectively. The 4S had an additional VSI crusher to 3S crushing. Three coarse and three fine aggregate sizes were used in the study.

Cone Crushers deliver a 4:1 to 6:1 reduction ratio. A Cone Crusher with coarse-style liners would typically have a 6:1 reduction ratio, though reduction ratios of 8:1 may be possible in certain coarse crushing applications. Fine liner configurations typically have reduction ratios of 4:1 to 6:1.

Manufactured sand is created by passing hard stones of various sizes via primary and secondary crushers (Jaw crusher and Cone crusher), reducing the particle size to those of sand. Because of its unique design and attrition action, the VSI crusher generates cubical and angular fine aggregate particles.

A wide range of liners are available to accommodate coarse and fine feeds, but which you choose depends on several factors. The most important factor in Cone Crusher liner selection is the feed. You should have a well-graded feed going into the crushing chamber. A well-graded feed is … See more

The final product sizes are fine, medium or coarse depending on the closed set spacing, the configuration of the crushing chamber and classifier performance, which is always installed in parallel. For finer product sizes, i.e., less than 6 mm, special cone crushers known as Gyradisc crushers are available.

A single hammermill crusher can break coal into shape at one time, integrating coarse and medium crushing, saving process and investment costs. The hammer crusher works by using a series of rotating hammers to crush material and produce fine powders. Capacity: 1-3,000 t/h Feed size: ≤1,000 mm Output size: 5-35 mm

Vertical shaft impact crushers (VSI) are commonly used in the production of high-quality manufactured sand and are ideal for producing a cubical-shaped product. Cone crushers are well-suited for producing a fine product size, while roll crushers are used for producing a finer product size and are often used in the mining industry.

The purpose of intermediate crushing is to produce several coarse-grade products – for example, road base aggregates – or to prepare material for final recrushing. ... except that the product be suitable for fine crushing. …
