Description

Technical Field

[0001] This utility model relates to the technical field of single-roll crushing mechanisms, and in particular to a movable single-roll crushing mechanism for crushing block materials. Background Technology

[0002] In modern industrial production and resource processing, the demand for crushed materials is widespread in various industries such as ore mining, building demolition, and solid waste treatment. Taking ore mining as an example, the raw ore extracted from mines is usually large in volume and needs to be crushed to a suitable particle size before it can be processed into subsequent beneficiation and smelting processes. In the resource utilization of construction waste, a large amount of waste concrete and brick blocks can only be reused as recycled aggregates in road paving and building material production after crushing. The vast majority of these materials need to be recycled through crushing. The performance of crushing equipment directly affects the efficiency of resource recovery and economic benefits. At the same time, as industrial production models develop towards high efficiency and flexibility, and as the requirements for the mobility and adaptability of crushing equipment for comprehensive resource utilization continue to increase, the development of equipment that can be quickly moved, flexibly deployed, and efficiently crushed in different types of materials has become an urgent need in the industry.

[0003] Currently, single-roll crushing devices on the market mainly consist of a crushing mechanism and an adjustment mechanism. Traditional block crushing equipment, such as jaw crushers, cone crushers, and impact crushers, while having high crushing efficiency in fixed operating scenarios, has significant limitations. These devices are usually large and heavy, and are mostly fixed installations, making them difficult to adapt to working environments with dispersed locations and frequent relocation. At the same time, existing single-roll crushers are mostly fixed or semi-fixed structures, which also have the problem of inconvenience in moving them. When they are working, the material is fed into the crushing chamber by gravity and crushed by the squeezing and shearing action between the rotating crushing rollers and crushing plates. However, in actual operation, due to the lack of mobility, when the working location changes, it is necessary to use large transportation equipment for overall transportation, which is not only costly but also prone to causing loosening and damage to equipment parts, affecting the service life of the equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a movable single-roll crushing mechanism for crushing block materials, aiming to improve the problem that it is inconvenient to adjust the angle and height when feeding material in the traditional single-roll crushing device in the prior art.
