Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
Marcy® Gy-Roll Cone Crushers reduce 10 mm (1/2'') feed to 2mm (10 mesh) final size, depending on material type. They are well suited for medium hard to hard materials, such as aggregate and mineral ores. These crushers are powerful and tough enough for continuous demands of pilot plant or small production applications.
Gyratory crusher: feed diameter 0.75 to 1.5m; reduction ratio 5:1 to 10:1, usually 8:1; capacity 140 to 1000 kg/s; Mohs hardness <9. More suitable for slabby feeds than jaw crusher. [reduction by compression]. Roll crusher: feed diameter 1 cm: reduction ratio 5:1 to 10:1; capacity 0.3 to 20 kg/s: Mohs hardness < 7.5.
This diagram illustrates the stages of s ize reduction from 1000mm to 4 mm. 3 . ... Crushers may be used to reduce the size, or change the form, of waste materials so they can be more .
Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
12%The size reduction process of rocks in cone crushers is one of the most important issues, particularly for the secondary and tertiary stages of crushing operations. In this study, 17 different rock types were considered for the evaluation of their size reduction variations that occurred in a laboratory-scale cone crusher. Based on several mineralogical, physico-mechanical, …

Thus, comminution energy depends only on the reduction ratio and is independent of original size of feed. Limitation of Kick's law: The energy required for reducing a 200 mm particle to 50 mm size will be the same as that for a 2 mm particle to 0.5 mm. In fact, higher amount of energy is required for reducing fine particles to still finer ...
HammerMaster Crushers are limited by horsepower and feed size, so depending on the grate selection and desired product size in closed circuit, reduction ratios will range between 6:1 to as much as 20:1. LimeMaster Crushers are also limited by horsepower and feed size, so whether you are looking to make a coarse 3/8" chemical lime or a typical

A plastic granulator ensures smooth size reduction of plastic and rubbery products, such as PP, PE, PET, PVC in all sizes.The plastic crusher is usually used as secondary shredding due to its high rotational speed and sharp blades.. Featuring robust welded steel construction and stable operation, but during crushing, metal and similar hard foreign objects are not ...
HPRG (from 50 mm to 3 mm size), as a primary grinding step; 2. VM grinding (from 3 mm to 150 µm; in one stage), as a final grinding phase. Your choice seems to be right at this phase of the project (low OPEX and even lower CAPEX than SAG and 2 BM stages), but the tests are required, as follows:
The feed is limited to 1 to 1.5 meters in size. Thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm. Typical reduction ratios are: Primary crusher: 3:1 to 10:1; Secondary crusher: 6:1 to 8:1; Tertiary crusher: 10:1 Therefore, if a 3 mm crusher product is required, maximum feed size to the secondary crusher would be 240 mm.

CSJ series rotary knife grinding machine, which consists of feed hopper, rotary and stator knives, bottom sieves and/or dust collector, is designed for fast particle size reduction from 300mm to 2mm …
Our jaw crushers are of the single-toggle type and feature a deep, symmetrical crushing chamber, a large feed opening for its size, and an ideal nip angle that offers smooth material flow and high reduction efficiency. Jaw crushers are normally capable of a reduction ratio …
In Proses Makina Systems where shredder and crusher are together, 25-30 mm sized grains coming out of the shredder come directly to the crusher in the system. Here, the grain size is further reduced and the resulting product size is around 1 mm. For Recycling Systems, it is important to make a size reduction.
The SR series single shaft shredder is popular size reduction machine used for materials that contain minimal amounts of metal, such as plastic, paper, wood, waste wires and cables. The screen mesh size is determined by material nature and subsequent processing requirements. The shredded particles can then be reused or further processed.
Jaw Crushers 7 The BB 50 is designed for a very efficient and convenient size reduction pro-cess. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotat- ing direction is helpful if too much sample material has been fed to the crusher causing it to block.
To determine the qualities of the Ferroalloys the pieces of alloy (60-70 mm) are sampled and then reduced. The steel company used to reduce the 25 kg of materials using a jaw crusher (reduction down to 10 mm). After the primary crushing the operator needed to grab the material from underneath the machine and put it in a rolls crusher.
Types of Size Reduction Equipment Crushers (coarse and fine) Crushers are slow speed machines for coarse reduction of large quantities of solids • Crusher do the heavy work of breaking large pieces of solid material into small lumps • A primary crusher operates on run-of -mine material accepting anything that comes from mine face and ...
The size, which is around 50–80 mm, of the ore or rock from the secondary crushing process is reduced to between 5 and 12 mm. We call the machine that performs the CRUSHING process a CRUSHING MACHINE or CRUSHER. MEKA Size Reduction Machines WHAT IS A JAW CRUSHER? / JAW CRUSHER.

Gyradisk Cone Crusher. For finer size products (e.g., -6 mm), a special cone crusher known as the Gyradisc is commonly used. Operation is similar to the Standard Cone Head; however, breakage is mostly by attrition rather than impact. Reduction ratio is around 8:1. Feed size is limited to less than 50 mm with a nip angle between 25 ° and 30 °.
The Rocklabs Boyd Crusher is believed to be the only jaw crusher in the world with a 25 times size reduction in one pass. Up to 50 mm pieces can be crushed to 2 mm or less in one operation. Jaws can hold up to 5kg of samples at one load. These jaws are flat 300mm wide jaws for ease of cleaning and also can be turned top to bottom for double life.
10) considering only two different size fractions, namely − 9.52 + 6.3 mm and − 6.3 mm + 4.75 mm. For these size fractions, 5.00-mm and 3.15-mm bar sieves were used, respectively (Fig. 7 h). The DRC of the sandstones was quantified, considering the variations in the SRR and Δ n values that were determined by Eqs.
The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.
Crushing is classified into to primary and secondary processes in which the size is reduced from large lumps, can reach 1m, to 2mm like the jaw crusher. The grinding is used to obtain finer ...
