EFFECT higher efficiency of crushing of super hard and abrasive materials without increase in motor output.
The invention relates to mining processing and enrichment of minerals and can be used in mining and construction industry in the crushing of the raw material.
Jaw crushers provide maximum crushing pressure on the crushed material compared with other crushers so they are indispensable for crushing solid large abrasive materials. As a result processing factories for the production of crushed stone and cement jaw crusher is installed in the head manufacturing process the first crushing stage where you need the most high crushing pressure. Therefore stable operation of jaw crushers depends on the performance of the whole production.
Jaw crusher with a simple swing of the movable cheeks are typical as all domestic and foreign crusher with a simple motion of the jaw have the same design and differ only in size and some unimportant changes in the solution of individual nodes 1. The working principle is similar when the rotation of the eccentric shaft rod receives a reciprocating motion in the vertical plane which by the spacer plates is transmitted to the mobile cheek. In this case the angle between the spacer plates is constantly changing lets call it the m of spreading plates.
Due to the fact that well-known jaw crusher have a low degree of fragmentation within 4-6 manufacturing to obtain the necessary fineness crushing used three - and even chetyrehstvolnym circuit crushing. This dramatically increases the cost of the crushing process and requires large power consumption.
It is known that in order to simplify mnogostadiinykh schemes crushing and reducing the cost of the crushing process design Jaw crusher with high crushing patent RF 2458740 publ. bull. No. 23 2012.
To prevent this proposed design Jaw crusher impact-crushing action with high degree of fragmentation in which the mass of the connecting rod and spacer plates create an additional impact contributing to fragmentation by way of crushing high strength materials without increasing power of the electric motor.
The aim of the present invention is the design of jaw crusher for crushing high strength abrasive materials with a high degree of fragmentation without increasing power of the electric motor.
According to the invention this objective is achieved in that the spacer plate in the crusher is installed on the rod above the top corner strutted up unlike the design of the crusher according to the patent of Russian Federation 2458740 and the top of the rod if necessary can be attached more weight contributing to an increase of the impact force at the time of crushing.
The extra load on the rod will increase the total mass of the crusher as the load will be compensated by reducing the mass of the flywheel. In the construction of jaw crusher with high crushing no idling therefore does not require large mass of the flywheel smoothing peak loads on the motor.
With a lab-scale jaw crusher as a test case an optimisation was made on how to operate it most energy-efficiently by using an evolutionary algorithm numerical method. For a selected optimised case an attempt was made to simulate the jaw crusher using a commercial software for discrete element modelling DEM after first simulating single .
