  • Why does a horizontal screen have more g-force than an inclined screen?

    Apr 09, 2020

    In this video, Mike Stecker, Lead Project Engineer at Telsmith, explains why a horizontal screen has more g-force than an inclined screen. A horizontal screen tends to have more g-force or acceleration than an inclined screen because it has a greater throw. The throw on an inclined screen is usually around 3/8″ whereas the throw on a horizontal screen is closer to 7/16″ The reason for this has to do with the shape of the…

  • What is the hybrid thrust bearing on the Titan Series Cone Crushers?

    Mar 02, 2020

    In this video, Rob Wheeler, Project Engineer at Telsmith, explains what the hybrid thrust bearing is on the Titan Series cones and why it’s an advantage. Hybrid is something composed of two different components: Hydro-Dynamic and Hydro-Static lift. 1. Hydro-Static is where we apply external pressure from our lubrication system. That pressure gets between the bearing and the bronze that it runs against, which physically lifts the components. It has a very large surface area…

  • What is a Jaw Crusher?

    Jul 16, 2019

    A jaw crusher is a compression type crusher, comprised of a fixed jaw and moving jaw positioned in a (V). The movable jaw compresses material against the fixed jaw, crushing the material to the desired size. The material exits the jaw through the bottom of the crusher otherwise known as the discharge opening. Changing the discharge opening controls the product size made by the crusher. Jaw crushers are mainly used at the primary stage of…

  • What is the difference between a Cone Crusher and an Impact Crusher?

    Jun 18, 2019

    Generally speaking, the major differences between Impact Crushers, both vertical shaft (VSI) and horizontal shaft (HSI), and Cone Crushers is the type of crushing force. Impact crushers crush by material impacting another object. Cone crushers use compression crushing where the material is crushed by being squeezed or compressed between two crushing surfaces. Selection of the type of crusher and the crushing process for any application depends on material hardness, and density of the material, feed…

  • What is an Impact Crusher?

    Jun 11, 2019

    The Aggregate Industry (Cement, Ready-Mix Concrete, Asphalt, Crushed Stone, Sand & Gravel), wants to process rock, sand, and gravel into a salable product as efficiently and inexpensively as possible. One such way to process these materials is sending gravel, rock, and sand through an Impact Crusher, which breaks up the material by either striking it with a rapidly moving blow bar or by throwing it into a stationary anvil where it breaks upon impact. Impact…

  • What is a Cone Crusher?

    Jun 04, 2019

    Cone crushers are a type of compression crusher used by aggregate, coal, concrete, crushing, fracking sand, and mining industries, which reduces material by squeezing or compressing it until it breaks. Specifically, the material is compressed between an eccentrically rotating piece of steel, the mantle, and a stationary piece of steel, the bowl. The material works its way down along the crushing chamber as it gets smaller, until the crushed material discharges at the bottom of…
