Stone crushers are extensively used to crush bulk and heavy stones into different sizes efficiently and reliably, be it at quarries or recycling plants. There has been a considerable rise in mining activities across the world to meet the burgeoning requirement of valuable minerals or other geological materials.

With the realization of one brilliant idea, Alton Scott Newell Sr. revolutionized the scrap metal industry and significantly contributed to the ongoing effort to recycle used metals and conserve the Earth's precious resources.

Introduction. Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue. It is generally a dry operation and is usually performed in two or three stages.

Second and earliest surviving automobile shredder for recycling scrap metal. This machine, designed by Alton S. Newell, efficiently reduced automobile bodies into scrap metal for recycling. A body was fed into the shredder at a controlled rate, and rotating hammers, driven by a 500-hp motor, shredded it into small pieces that were easily shipped.

The shredder machine designed by Alton S. Newell in 1969 efficiently reduced automobile bodies into scrap metal for recycling. An automobile's body was fed into the shredder at a controlled rate, and rotating hammers, driven by a 500-hp motor, shredded it into small pieces that were easily shipped.

Industrial crushers reduce large rocks, ore, or waste materials to smaller sizes. They are the first level of size reducer; further granularization occurs in grinding mills or pulverizers. Crushing devices hold feed material between two solid surfaces and apply sufficient force to fracture or deform that material.

There have been a number of improvements to the basic jaw and gyratory crusher designs throughout the past 150 years, but in many ways these modern crushers still use the same basic approach to crushing rock.

His invention of the Newell Shredder offered a method of scrapping metal that created a better end product with dras-tically reduced energy and processing cost. The development of the shredder was the product of many years of …

Mr. Newell's original metal shredders were designed to shred steel cans for a leach precipitation process used to refine copper. Demand for the material grew, and as it did the Newell family developed larger shredders to process heavier material.
