Capacities Open side settings of discharge opening The above capacities are based on an assumed feed where 100% of the feed passes 80% of the feed opening. 80% of the feed passes 60% of the feed topsize, and 50% of the feed passes a sieve size that is 10% of the topsize.
Material exits the crusher through the open side setting. Thus, the top size of the product is determined by the open side setting. Vertical view of the crushing action [image: (135-5-17)] Long Shaft Gyratory (generally, not used commercially)
The three main types of crushers are the cone crusher, the jaw crusher, and the impact crusher. Make sure you understand all of the differences between these kinds before choosing one for your project. Regardless of which type of machine you choose, you should be …
crusher is the set and on jaw and gyratory the open-side set (OSS) is specified. This reflects the fact that considerable portions of the processed material fall through the crusher at OSS and this determines the characteristics size of the product. The set of a crusher can be varied in the field and some crushers

Pioneer Jaw Crushers. 25% more capacity than competitive units. Quick closed-side setting adjustment for enhanced safety. Class-leading stroke offers greater throughput.
Apr 28, 2017 An example of the effect that crusher setting has on the product gradation is as follows: If the target crusher setting is 3/8 in. (10 mm) but the setting is not checked and it wears open to 1/2 in. (13 mm), then the end result is a 15 percent decrease in the minus 3/8-in. (10 mm) material size.
Crusher Vision is an automated closed side setting system for gyratory crushers that measures the gap between the concave and mantle. Crusher Vision has developed patented novel technology that offers the mining sector the opportunity to increase throughput, decrease maintenance costs, decrease power consumption and greatly reduces the safety concerns by implementing a system for non ...
Measurement of the crusher’s closed side setting varies depending on the jaw profile that is being used and has an impact on the crusher’s capacity and . product gradation. The following factors will enhance crusher capacity and performance: 1. Proper selection of the jaws. 2. Proper feed gradation.
Mintap is the official worldwide distributor of the C-Gap closed side setting measurement tool for mining and quarrying clients. C-Gap enables operators to measure the closed side setting (CSS) of gyratory, jaw and cone crushers, to improve safety standards, production levels and costs. The C-Gap allows for the measurement of CSS’s between ...
Jan 17, 2016 Open side setting (OSS) The open side setting is measured when the crusher is at rest. The setting is measured either top to top, or bottom to top, depending on the tooth profile of the jaw dies. Closed side setting (CSS) The closed side setting can be …
push button control of the crusher, track and feeder functions. DYNAMIC CLOSED SIDE SETTING (CSS) Dynamic adjust-closed side setting (CSS) can be changed while operating, minimizing downtime. CRUSHING CHAMBER Built to be reliable in the toughest operating conditions, producing material ranging from 3/8” to 2”. FEEDER Heavy Duty Hardox ...
Sep 01, 2021 The Crusher category includes jaw, impact, horizontal shaft impact, and cone crushers, among others, which are designed to turn larger rocks down into smaller ones that can then be more easily passed through screens. Crushers are used in waste management and recycling centers.
5 rows The eccentricity causes the cone head to oscillate between the open side setting (o.s.s.) ...
The above figures represent through the crusher capacities, which are based on a feed material with an average specific gravity of 2,7 t/m3, a maximum feed size that will enter the crusher without bridging and material finer than the crusher closed side setting removed. The capacities may vary
Feb 17, 2016 CRUSHER: 42-65 Primary gyratory Open Side Setting: 5″; Eccentric Throw: 1″ Recommended Operating Speed; 400 Rpm (Approximately 80% of Maximum Speed) Capacity at Recommended Speed: 438 Short Ton/Hour Maximum Horsepower Allowable at Selected Throw and Speed: 213 Horsepower. FEED SIZE: (F) 80% Passes 28″ (66% of Feed Opening)
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) - Gyratory’s: typically 90 to 220mm-Secondary’s: typically 30-60mm-Tertiary’s/Scats: typically 8-20mm-Jaw Crushers: 80-150mm
Jun 03, 2020 The distance between the mantle and the side is the primary area where cone crushers can be adjusted. These settings are known as the OSS (open side setting) and CSS (closed side setting.) The opening on the open side determines the maximum particle size of the finished product.
Apr 25, 2015 Get your dial indicator set up on a good surface with as straight of an angle as possible to a tooth to read backlash and start reducing the backlash to .0005 -.0015 by turning the adjusters equal amounts, once your within the range torque the 2nd cap bolt on the cap opposite the gear teeth.
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.
The capacity of jaw crushers is a measure of the mass or volume of crushed material produced in unit time of operation. The capacity is primarily a function of: 1. crusher design characteristics such as width and depth of the crushing chamber, 2. open and closed side settings,
