After measuring the crusher’s OSS, the CSS should be calculated to define what the opening of the crusher is to be and enable adjustment to the desired setting. The way we measure the opening varies according to the profile of the jaw: top-top, top-bottom or bottom-top. The tables for the cavity should be checked to figure out which way
The size of the crushing force is an important index to measure the performance of the crusher The greater the crushing force is the higher the crushing effect is in the condition of the nature of the ore The cone crusher bines the higher speed with the stroke and greatly improves the rated power and passing capacity of the equipment.
May 13, 2019 Gradations of cone feed and crusher discharge must be monitored as a crushing/reduction performance indicator and as a liner wear indicator. This should be done at least once a month, and more often if required at the site. Daily inspections below the crusher should be made to ensure no bridging, plugging or foreign material are under the crusher.
To check the gap on a crusher a procedure called LEADING is done. A lump of lead, whose dimensions are greater than the gap of the crusher, is lowered through the crusher while the crusher is running. The lead is pulled back through the crusher very slowly to be sure that it is flattened as far as it can be. The narrowest point on the lead is then measured. This will be the

When a gyratory crusher's mantle is replaced, how does the operator know that the correct product size is being achieved at start-up? How does one Evaluate or Estimate to best control a Crusher Product Size ?
Just like the measurement of pH in a Flotation circuit or mill power, if you can’t measure it, you can’t manage it, and if you can’t manage it, you can’t improve it. For the Crusher, this is just as relevant. Like most things, if it’s easy and the results are accurate, the task will most likely be adopted and accepted.
Considering the complexity of multidimension parameters and the mechanical performance of a 6-DOF robotic crusher, a multiobjective optimization function based on the transmission index and condition number is established. As an important operation in the screw theory, the reciprocal product between the transmission wrench screw of an actuator and the output twist screw of

Obviously, dimension is in essence just measuring the maximum size of the material that will be fed into the crusher. The granulometric requirement is based on how the final product will be used. However, abrasiveness and hardness factor are known through testing and calculation.
Crusher design evolutionCompression cone crusher designs today have evolved from the simple cone crusher first developed in the mid-1920s by Edgar B. Symons, to the modern high performance crushers. Early crushers used springs for
3. Shut down crusher. Clean loose rocks, isolate crusher, feeders and conveyor belts (2 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 (1 hour) Time taken- 4.5 hours production downtime
This is the starting point for understanding how cone crushers work – and how they can make your mine or quarry more productive. Elsewhere on the site you can find detailed information about all aspects of crushing and screening, but to make sense of these it helps to understand the basics of cone crushing. That’s what you’ll find here!
Nov 01, 2004 Wear measurements were taken for in-service crushers during the research period using a novel laser profile measurement device. Data from the wear measurements was correlated with crusher production information such as current draw and throughput. This work resulted in enhanced knowledge of liner wear and its link to crusher performance.
The purpose of this test is to quantitatively measure air velocity at the hood face. Equipment a. Anemometer, either mechanical or electrical, that has been recently calibrated. It shall be capable of measuring in the range of 50 to 400 fpm (0.25 m/s to 2.0 m/s) with an accuracy of 5% of the reading. b. Notebook for recording observations ...
Poor feed arrangements affect crusher performance, liner life and the life of mechanical components, so it is crucial that you can identify and deal with any problems. In general terms, the goal is evenly distributed, non-segregated feed. It sounds straightforward, but issues can quickly develop if yoursquo;re not vigilant. Here are the most common problems to look out for, and

crusher was greater at the join in the lining. Allowing material with increased fragment size to pass through this area has potential for impact on downstream processing performance. A dramatic reduction in time spent measuring the crusher lining, combined with a significant increase in accuracy of data captured by I-Site laser scan
degraded performance. In choosing an ore level measuring technology to achieve optimum crusher performance, Vale engineers looked for quick response and high accuracy. According to Jack MacIssac, Automation Production Leader at the mine, ore levels in the crusher jaws can vary from 8 to 15 ft (2.44 to 4.57 m).

Primary Crusher — The first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary or tertiary crushers. Product — Output from the crusher. Reduction Ratio — The ratio of the top size of input material to the top size of crusher discharge.
2. Indirect Measurement Method This kind of measurement method is to measure the stress of some certain components and parts, and figure out the magnitude of the crushing force as well as the places of points of action. Its largest merit is that it doesn’t need to process specialized teat master copy, nor to repair or transform the jaw crusher.
The system continuously optimizes crusher performance without overloading it, so you get the most out of your crusher. It can automatically adjust crusher settings to compensate for crushing chamber wear – ensuring consistent product size.
how to measure output of a crusher plant . GM stone crusher machine is designed to achieve maximum productivity and high reduction ratio. From large primary jaw crusher and impact crusher to cone crusher and VSI series for secondary or tertiary stone crushing, GM can supply the right crusher as well as complete crushing plant to meet your material reduction
Oct 01, 2018 Power draw measurement is a suitable method due to its installation being nonintrusive, the required investment resources are low and the measurement is sufficiently accurate. The crusher operation can be affected by multiple factors such as a miss-aligned feed, feed segregation and stiffness and shape of the material.
No method of measuring chamber pressure is 100% accurate. If you measure 100 rounds of exactly the same load, in exactly the same gun, with exactly the same test equipment using the crusher method the measurements will typically vary plus or minus 5% from round to round. Some rounds may be off from the average for that group by 10% or more.
For example, a 900x650 mm crusher refers to a crusher with an inlet measuring 900 mm by 650 mm. The main parts and main technical parameters of a jaw crusher are presented below. 1. Feed Chute 2. Drive Flywheel 3. V-belts 4. Electric motor 5. Motor Stand 6. Settings and Damping Group 7. Hydraulic Cylinder 8. Toggle Plate 9. Swing Jaw 10. Discharge
These crushers are invariably operated in closed circuit. 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.
