Portable Plants Key details One detail that was particularly important in the Anderson Columbia impactor plants was the selection of three bar rotors adds Tim Harms crushing and screening product manager at KPI According to Harms the use of two three bar rotors as opposed to four bar rotors gives the plant the maximum amount of flexibility in Anderson Columbias application because the secondary crusher can serve as a primary crusher when needed The main focus is proper penetration Harms says We need proper penetration of the blow bar circumference at the right speed so the material is struck by the bar rather than glancing off of the edge of the bar if the rotor is moving too fast or conversely over penetrating into the rotor core if the rotor runs too slow Four bar offers similar advantages but there are some things that are a little more defined Harms adds In any setup with the three bars we have a good combination of timing and were able to adjust the speed to give a very good performance in a broad range of applications If this plant was always run strictly as a primary and a secondary then we may have made a different selection for the rotor in the secondary The plants ability to handle the Tejas Quarrys clay heavy material is another feature that stands out says Taylor OBryan material handling sales engineer at KPI The amount of clay in the shot fluctuates OBryan says So the primary plant is equipped with a gate that can reject an awful lot of the finer clay contamination when necessary Or conversely if the material is cleaner the finer material from the shot can be sent forward to the remainder of the plant According to Harms the system may reject as much as one third of material but its more cost effective for Anderson Columbia to deal with undesirables on the front end versus downstream After all ACHIEVE DAILY TARGETS 57 COLOR TOUCH SCREEN SMART LOCATIONS A t 1259 PM GAP 40 FB446 116 t h Loads 53 8520 1 6480 15000 Transforming the way the world works 2017 Trimble Inc All rights reserved P Q 7 17 PRECISE WEIGHING ETICKETS ON THE MONEY EVERY TIME Trimble LOADRITE L3180 SmartScale for loaders When the pressure is on and customers are waiting you need to perform faster without compromising accuracy and precision Get moving and find out more at trimble com L3180 email info@ loadritescales com or call 18005285623 Above anderson Columbias Tejas Quarry is located in New Braunfels Texas between Cemex and lehigh Hanson sites according to Dan Johnson vice president and general manager 20 Pit QUarry August 2017 pitandquarry com
