Optimisation of the swinging jaw design for a single toggle jaw crusher
Abstract This study reports on the design optimisation of the swinging jaw crusher plate. Jaw crusher machines are used in the mining and construction industry for W = CJC x CSS / G. Where: W = Width of Crusher. C JC = Capacity of Jaw Crushers. G = Gape Size. CSS = Closed Single Setting of Jaw Crushers.

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].According to Chinese jaw crusher manufacturer’s data [ 21 ], the PE 400 by 600 single toggle jaw crusher has 30 kW motor power and an input eccentric shaft speed of 275 rpm or 28.7979 radians per second. Assuming that the input speed is constant, the input torque is found to be 1.0417 kNm.Analysis of the Single Toggle Jaw Crusher Force

Optimisation of the swinging jaw design for a single toggle jaw crusher
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 It must be at least 36 in. wide for an 18 x 36 jaw crusher. So a 4-ft by 8-ft screen would be acceptable. The 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft. The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft.Crusher Efficiency Calculations 911 Metallurgist

OPTIMUM DESIGN AND ANALYSIS OF SINGLE TOGGLE
Mechanism of a typical single toggle jaw crusher can be treated as a crank-rocker mechanism of a four-bar linkage having; frame as a fixed link, crank as an eccentric shaft, liner as coupler and toggle plate as follower as shown in the Fig 1 TABLE1 PE300*900 Jaw Crusher Calculation Parameters [12] r(mm) l(mm) k(mm) 12 1085 455The main reason for this inefficiency is in the random distribution of forces on the particles inside the crusher. With certain simplifications, the theoretical energy efficiency of comminution can be estimated to fall between 5 and 10 % (Legendre & Zevenhoven, 2014) while the measured energy efficiency in actual comminution testing Assessing the energy efficiency of a jaw crusher ScienceDirect

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).fixed jaw of the jaw crusher. In order to achieve the goal, it is necessary to solve the following subtasks: 1. To develop a mathematical model of the body of the crusher fixed jaw. 2. To develop an algorithm for optimizing the body of the fixed jaw of jaw crusher. 3. To develop recommendations for designing the body of the fixed jaw of jawDevelopment of methods for optimizing the parameters

Calculation of flakiness index hides variation of particle shape within a gradation. • Mechanical properties are highly affected by sample preparation. Abstract. A parameter study using a jaw crusher is designed to investigate the influence of feed gradation, feed rate, crusher setting and crusher speed on the crusher operation and theBy 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.

Capacities and perforiDance characteristics of jaw
power requirements of jaw crushers. Introduction Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw The maximum feed size is approximately 8 0% of the feed opening. The open side setting is measured when the crusher is at rest. The setting is measured either top to top, or bottom to top, depending on the tooth profile of the jaw dies. The closed side setting can be calculated by deducting the stroke from the OSS.Crusher Close Side Settings 911 Metallurgist
