Currently, many quarries do not produce significant quantities of aggregate coarser than 20 mm. It is not unusual, though, for material coarser than 10 mm to be stockpiled for further crushing. To keep your site crushing efficiently and reduce the number of fines produced, here are some tips and best practices you can follow: Feeding jaw …
The process "Comminution" involves size reduction and size-wise classification called as screening or separation. The objective of this report is to provide the details of size reduction...
Features & Benefits. A Cone Crusher will deliver a 4:1 to 6:1 reduction ratio. As we set the closed side setting tighter to create a finer output, we also reduce the volume or throughput capacity of the machine. Generally speaking, multiplying the closed side setting by two is a good guide to the top size of the gradation exiting the machine.

The magnetic separator is one of the most widely used and highly versatile models in the industry, and is suitable for the separation of substances with magnetic differences The magnetic separation equipment of Mecru has the advantages of simple structure, large processing capacity, convenient …
A crusher of these dimensions will break 40 tons per hour to 2½-in. size with a power consumption of 30 h.p. On the other hand, a 14-in. gyratory crusher, working as it should at full capacity, will crush 100 tons per hour to the same size with a power consumption of 70 h.p. ; at 40 tons per hour, it would still require about 50 h.p.
The actual minimum setting is at which the crusher will operate without causing ring bounce. Feed type Feed material characteristics such as gradation, bulk density, moisture, clay content, and crushability have …
4 Lubricate your machine regularly. Lubricate important parts like mainshaft, bearings, mantle and concave can make the whole production smooth and minimize the downtime. 5 Clean your oil tank if it …
A typical Double Roll Crusher will generate a minimum crushed product size of approximately ¼" (6mm), assuming the feed size allows for a crushing ratio appropriate for the machine in question. It is worth noting that there are specially designed Roll Crushers available that are specified to produce smaller crushed product sizes, potentially ...

Standard crusher feed sizes range from 1067 mm (42") to 1829 mm (72"). The 1067 mm gyratory crusher has essentially the same capacity as the 1600 mm (1600 x 2000) jaw crusher. Gyratory crushers …
There is a variety of things to take into consideration when selecting a cone crusher chamber profile to best suit your needs. An inadequate liner profile can lead to increased downtime through excess liner wear, low efficiency and, in some cases, even mechanical damage to the crusher. To ensure the suitability of the liner profile for its ...

It is important to match the CSS of the crusher to the top size of the product to be produced. If the circuit is being closed at 25mm (1") to produce a 25mm minus product, the crusher should be set at, near or slightly below 25mm. { {image3-a:l-w:640}} Impact crushers An impact crusher uses mass and velocity to break down feed material.
The minimum discharge setting should not exceed full-load amps. ... Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with the feed. The initial impact is responsible for more than 60% of the crushing action, with the remainder being made up of impact against an adjustable breaker ...
A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4" closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. 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.
Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm, or 200mm, depending on the size of the crusher. Cone crushers can form finished …
But while operating a process plant, it is more important that the crushing efficiency is defined in terms of the requirement of subsequent process. The Process plant has been designed for coal size - 13 mm ( 80 % passing). The 610 mm dia cyclones are inefficient at sizes less than 3 mm.
Crusher run gravel is typically used for driveways and ub-bases, or it is refined further with a screening plant to produce base (surface) materials or clear stone products.
