Jul 14, 2021 The widest distance is called the open side setting (OSS) and the narrowest distance is called the closed side setting (CSS). These settings are important. the OSS is the maximum distance between the concave surface at the bottom of the crusher and the mantle, and therefore it determines the maximum size of the discharge product. the CSS, as ...
Particles of size 3, smaller than the open set of the crusher, can travel down faster and occupy or pass through the lower portion of the crusher while the jaw swings away. In the next cycle the probability of the larger particles (size 2) breaking is greater than the smaller sized particle 3.
a maximum feed size that will enter the crusher without bridging and material finer than the crushers closed side setting removed. The capacities may vary depending on the feeding method and on feed characteristics such as gradation, bulk density, moisture, clay
Cone crushers are often placed within the secondary crushing station because they are versatile in terms of feed, closed side setting, speed, and throw. With cone crushers, though, it is essential to operate them at consistent choked settings to keep productivity up. 3. Tertiary/Quaternary/Final Reduction Crushing
Feed Opening Size. The feed opening size is about 80% of the feed opening. Automation. Crusher technology keeps evolving in terms of automation and safety. Some of todays crushers are equipped with systems that will adjust the CSS (Closed Side Setting) without your having to shut the machine down.
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. Chat Online
By operating the HP cone crusher on the lower end of its speed range, the product gradation can be shifted to produce fewer fines and a higher percentage of on-spec product. The HP cone crusher creates a higher value product with less waste. Mobile The NW300HP is a highly mobile, closed-circuit crushing and screening plant.

Jan 17, 2016 Closed side setting (CSS) The closed side setting can be calculated by deducting the stroke from the OSS. CSS is the most important crusher parameter since it defines the maximum product size and has significant bearing on capacity, product gradation, power draw, and wear. Nip angle The nip angle is the angle between the fixed and movable jaw dies.
for calculation of the closed-side setting (CSS) according to the size of the crusher to be adjusted. Example If the measurement of the OSS in the C160 model is 191mm (7 1/2), then the CSS will be 191 - 41 150 mm (7 1/2 1 5/8 5 7/8). By determining the CSS, we will know the closed side setting of the crusher instead of opening of
Crusher Close Side Settings - 911 Metallurgist 2016-1-17 Closed side setting (CSS) The closed side setting can be calculated by deducting the stroke from th
Crusher Operation What is the Closed Side Setting (CSS)?-Minimum gap setting of when the mantle bowl rotates within the crusher or moving plate is closest to the fixed plate in a jaw crusher (closed position) - Gyratorys typically 90 to 220mm-Secondarys typically 30-60mm-Tertiarys/Scats typically 8-20mm-Jaw Crushers 80-150mm
Measuring the Closed Side Setting (CSS) or Open Side Setting (OSS) is usually confusing as many methods are employed without understanding consequences. CSS is the smallest discharge opening dimension on the jaw. OSS is the largest discharge opening dimension on the jaw. It is equal to the CSS plus the throw of the swing stock.
setting of the crusher. Data from operating crusher machines indicate that both d1 and d2 are proportional to the closed side setting. d1 is the smallest size particle that can be retained in the crushing zone during the opening phase of the cycle. d2 is the largest particle that can fall through the crushing zone during the opening phase of the cycle.
The widest distance is known as the open side setting (OSS) and the narrowest, the closed side setting (CSS). These settings are important. The OSS is the largest distance between the concave and the mantle at the bottom of the crusher, so it determines the largest particle size of the outgoing product.
Jun 03, 2020 The closed side setting determines what the final size of the particles will be and that setting can be adjusted until youve reached the desired material size. Usually, these crushers deliver a 41, 51, or 61 reduction ratio. As you reduce the closed side setting to produce smaller material, you also reduce the capacity of the machine.
3. Shut down crusher. Clean loose rocks, isolate crusher, feeders and conveyor belts (1 hours) 4. Obtain access to bottom of crusher, inch crusher motor manually to ensure its at the closed position then measure gap with a tape measure or equivalent (1 hours) 5. Leave crusher, de-isolate, restart (0.5 hour) Time taken- 3 hours production downtime
The cone crushers are equipped with a hydraulic setting adjustment system, which adjusts closed side setting and thus affects product gradation. Depending on cone crusher, setting can be adjusted in two ways.
The Jaw Crusher is designed to handle this feed, but limits are Do not exceed the F80 rule on top size. This happens at times, just not a steady rate. The fine material size equal to the closed side setting should be removed prior to entering the crushing chamber. A best practice, if possible, is to blend the material arriving from the source.
