The size of a jaw crusher is usually described by the gape and the width, expressed as gape × width. The common crusher types, sizes and their performance are summarised in Table 4.1. Currently, the dimensions of the largest Blake-type jaw crusher in use are 1600 mm × 2514 mm with motor ratings of 250–300 kW.The plate dimensions of the un-optimised jaw crusher were modelled using ANSYS Design Modeller 2021, as shown in Fig. 3.The load and boundary conditions for the static structural analysis were as shown in Fig. 4.Design of Experiments (DoE) was then conducted where the minimum and maximum values of the target parameters were Optimisation of the swinging jaw design for a single toggle jaw crusher

2. Factors affecting jaw crusher capacity The mathematical model of the working process of the crusher should take into account many factors. Operating experience and investigations have shown that the performance of jaw crushers significantly depends on their design and the motion law of its function element the moving jaw [5], [6].Single-toggle jaw crushers are characterized by the swing jaw being suspended directly on the eccentric drive shaft and the lower part of the swing jaw being braced against the crusher frame by means of a toggle plate. The kinematics of this type of toggle system result in a higher capacity than that achieved with a double-toggle jaw Industrial Solutions Jaw crushers ThyssenKrupp

Advanced comminution modelling: Part 1 Crushers
As shown in Fig. 2 a, a large jaw crusher was used to reduce ore from the mine to an 80% passing size (P80) of 100–150 mm. A cone crusher was then used in closed circuit with a screen producing a 20–30 mm product which could then be fed with some added water into a tumbling mill filled with heavy steel rods (called a rod mill).PLEASE EXPALIN IN A N EXCEL SHEET TO CALCUALTE THE SAME.Performance calculator for ball mills based on dry milling method.

Capacities and performance characteristics of jaw crushers
By using the data of E.A. Hersam and F.C. Bond’s equation for energy consumption in comminution, a method was developed to analyze the performance of industrial jaw crushers. The study showed that industrial jaw crushers are generally operated below capacity. The study also showed that industrial jaw crushers generally have Jaw crusher performance contour plots. 3.2. DEM.
