The purpose of the Rock Crusher model is to visualize ALL the work required to go from "concept to cash," not just the work of coding. Often the work required to learn precisely what to build is invisible and therefore unmanaged. A Crusher is a backlog item (or Rock, in this metaphor), that makes learning "precisely what to build"
A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.

By selecting a suitable crusher, in addition to energy saving, it is also possible to achieve the required output quality of the aggregate in terms of the production program [10].
A jammed crusher should be locked out and tagged out, then the crusher setting should be opened - this will usually release the pressure on the tramp and allow the crusher to be dug out. Remember to check the flywheel positions as noted above, he added. Stalled cone crushers may also be jammed with tramp; in many cases, these …
The results of these studies showed that by reducing the level of comminution from d_80=53 μm to 65 μm≤d_80≤75 μm, in addition to increasing flotation efficiency to R = 90.16%, EE = 93.04% ...

In particular, the decarbonized economy is going to require copper for electricity transmission; lithium, nickel, graphite and cobalt for electric vehicle and grid-support batteries; aluminum for lightweight electric vehicles components; and rare earths for renewable energy plants such as wind turbines.
Preventive means that by making regular checklist and inspections to keep crushers in good condition. Maintenance checklist is usually set up on a daily (8 hours), weekly (40 hours), monthly (200 hours), yearly (2,000 hours). Only doing that, can you prolong the machine's life span and maximize its value in crushing process.

materials energy consumption in the two-stage crushing process was reduced by 30%. Key words: rock crushing, jaw crusher, crushing efficiency, two stage crushing process 1. INTRODUCTION The main aim of processing rock raw materials is to prepare and process the rocks to a condition that meets the commercial requirements for quality parameters as
It would seem as though the steel and iron contained in the rock crusher itself(about 50,000 lb.) would makealarger environmental impactonthe life cycleofthe rock crusher. However, the requirements to replace spares and wears over the 25 years ofthe rock crusher (8.76 E+5) greatly exceeds the primary quantity ofsteel and iron. USfPhase Breakdown
This inefficient use of connected horsepower will result in a higher energy cost per ton of material crushed (kW/hr per ton). The under-crusher discharge area should be inspected for built-up material on a daily (8 hour) basis. Example: Lost productivity and higher energy costs due to a clogged discharge area
The design and construction of a prototype rock crushing machine was performed this is with a view to ensuring that the designed crusher is capable of crushing rocks, lime stone and solid minerals for indigenous use. The research work was tailored mainly on the design and production of locally fabricated rock crushing machine for indigenous use.
