Explanation: The gyratory crusher involves the operation of both compression and impact at the same time, while jaw crusher only applies compression. 2. The feed size of gyratory crusher varies from ____ a) 150-190 mm b) 200-800 mm c) 500-600 mm d) 100-150 mm View Answer. Answer: a
It provides the formulas and values to calculate the critical speed, diameter, and capacity of the crusher under different operating conditions. This document contains a calculation sheet for determining the capacity of a crusher based on various operating parameters such as rotational speed, diameter, width, and material properties.
P80 = Product size of the jaw crusher (meters) This formula is used to determine the efficiency of the jaw crusher, as well as other types of crushers. The efficiency is dependent on a number of ...
Introduction: Jaw crushers are essential machines used in the mining and aggregate industries to break down large rocks into smaller, more manageable sizes. The primary function of a jaw crusher is to reduce the size of the material to a specific size range, commonly referred to as the reduction ratio.
The equation for Rittinger's Law can be written as: E = K R f c (1/L 2 – 1/L 1) Where: ... Jaw crusher. Mineral sizers are one of the newer technologies to the crushing industry.
