Abstract
The aim of the work is to develop new technological solutions for the use of composite materials to fill the cavities of cone crushers. The analysis of the methods of restoring the landing surfaces for the installation of armor and the supporting cup of cone crushers is carried out. The publication offers a fundamentally new technology for filling the cavities of conical shot-loks using special composite materials. As the filled material, the use of a polyurethane composite is justified. The composition of the composite material has been adjusted to achieve optimal technological performance. The proposed composite material is a relatively low viscosity composition that has a high flowability and a high penetrating power. Thanks to the presented technology it is achieved: providing the initial geometric dimensions of the crusher; Hardening of hardness seats up to 400 NV, i.е. almost twice as much as the original; increase the contact area of the lower seat with the cone armor and reduce the load on the seat; ensuring tight connection of the upper and lower seats of the cone with the seats of the armor. The complex of new technological solutions for restoration provides for the reduction of off-schedule stops of the crushers and, accordingly, the number of technically complex and dangerous repairs is reduced, the efficiency of the units is increased, and the operating costs are reduced. This recovery method significantly reduces the downtime of equipment and ensures the reliability of further operation.
