Products Description
In many fields such as mining, construction aggregate production, and construction waste treatment, efficient and flexible crushing equipment has always been the key that the industry pursues. As an outstanding crushing tool, the Tire-type Mobile Crusher for Granite is reshaping the pattern of crushing operations with its unique advantages.
The reason why the tire type granite mobile crusher can efficiently crush granite lies in its design matching the material characteristics of granite. From the crushing principle to the structural configuration, it solves the processing difficulties of granite in a targeted manner.
Key material properties of granite
As a typical representative of hard rock, the material properties of granite directly determine the technical requirements of crushing equipment. Its core features include.
Extreme hardness
The Mohs hardness level reaches 6-7, and traditional equipment is prone to the problem of rapid wear of components such as broken tooth plates and hammer heads, requiring the use of high-strength alloy materials.
01
Super compressive strength
The compressive strength is generally between 160-250MPa, significantly higher than soft rocks such as limestone, requiring equipment to have strong crushing force output capability.
02
Low toughness and high brittleness
It is prone to fracture along crystal gaps under external forces, but not prone to plastic deformation. It is suitable to use a combination of "impact extrusion" instead of relying solely on rolling technology.
03
Uniform composition and dense structure
The main components are quartz and feldspar, with a tight crystal structure and no obvious cracks. The crushing equipment needs to have a stable crushing chamber to ensure uniform material stress and avoid "over crushing" or "powder jamming".
04
Containing a small amount of impurities
Some granite contains high hardness quartz particles, which can easily cause local wear on broken parts. The equipment needs to be designed with wear-resistant materials and easily replaceable vulnerable parts.

How to adapt the tire type granite mobile crusher to the characteristics of granite?
In response to the above issues, the tire type mobile crusher achieves efficient crushing through dual optimization of "crushing principle+structural configuration".

Characteristics of Granite |
Adaptive design of tire type mobile crusher |
Core function |
|
High hardness, high compressive strength |
1. Adopting a combination of "jaw breakage+cone breakage" or "jaw breakage+impact breakage" crushing process 2. The crushing chamber adopts a "deep chamber V-shaped" design to increase the crushing stroke |
1. Jaw fracture first "coarse fragmentation" dissociates large hard rocks, followed by cone fracture/impact fracture and then "medium fine fragmentation", gradually releasing large crushing forces 2. Deep cavity design ensures sufficient material compression, avoids "empty hitting", and improves crushing efficiency |
|
Low toughness, high brittleness |
1. Impact breaking adopts the principle of "stone hitting stone" for crushing 2. Cone breaking adopts the principle of "laminated crushing" |
1. Use a high-speed rotating impeller to throw materials towards the counterattack plate, and achieve brittle fracture through material collision (stone hitting stone), reducing metal wear 2. Layered crushing generates cracks inside the rock through multi-directional squeezing pressure, adapting to high brittleness characteristics |
|
Dense structure and easy to get stuck material |
1. Equipped with hydraulic cleaning system 2. Install a grid screen at the feed inlet |
1. If the material is stuck, the hydraulic system can quickly lift the crushing chamber, clean the blockage, and avoid shutdown 2. Pre screen the soil and fine materials to prevent cavity blockage caused by the mixing of dense granite and impurities |
|
Easy to wear and break parts |
1. The crushing gear plate and hammer head are made of high chromium alloy or high manganese steel material 2. Modular design of vulnerable parts |
1. High hardness alloy material resists granite wear and extends service life 2. Modular design facilitates quick replacement and reduces downtime for maintenance |
|
Need to flexibly move homework (scene characteristics) |
Tire type chassis+traction device, suitable for mining and infrastructure sites |
Granite mining sites are mostly outdoor and scattered areas, and equipment can be directly moved to the material pile to reduce material transportation costs and improve operational flexibility |
1. Raw material input: A loader dumps granite into the hopper, which is then uniformly conveyed to the crushing chamber via a vibrating feeder to prevent material blockage and equipment overload.
2. Crushing Operations:
(1) Jaw Crusher: The moving jaw and stationary jaw move relative to each other, crushing large granite blocks into medium-sized particles through compression.
(2) Cone Crusher: The crushing wall periodically approaches the bowl liner, subjecting the material to multiple stresses during its oscillating motion, resulting in precise particle size control.
3. Screening and Recirculation:
The crushed material enters the vibrating screen. Qualified finished products are conveyed via a conveyor belt to the finished product pile, while unqualified material is returned to the crusher via a recirculation belt until the required particle size is achieved.
4. Environmental Protection Control: During operation, sealed conveyor belts, dust collectors, and spray systems work in tandem to reduce dust emissions; low-noise design minimizes impact on the surrounding environment.
Product Features
1. Strong Adaptability and Capability to Operate Anywhere：
The tire-type mobile crusher for granite adopts an integrated design. After arriving at the operation site, it can start operating quickly without the need for basic construction and complex debugging. Compared with traditional fixed crushing equipment, it can save 70% of the deployment time. In the dynamic mining scenario, the equipment can closely follow the direction of the ore vein and the mining progress in real time. Through the "on-site crushing" mode, it can directly process materials at the source, completely eliminating the long-distance transfer link of materials. As a result, the comprehensive transportation cost can be reduced by up to 60%, significantly improving the economic benefits of the project.
2. Powerful Power and High-efficiency Crushing
The tire-type mobile crusher for granite is equipped with a powerful power system, which is mainly aimed at materials with high hardness and hard texture such as granite. Its crushing equipment can select jaw crushers, impact crushers, cone crushers, etc. according to requirements. By making a reasonable selection of crushing equipment, the processing capacity of the machine can be made more powerful, and the production efficiency can be improved. The hourly output can reach dozens of tons or even hundreds of tons, fully meeting the needs of large-scale production.
3. Flexible Configuration and Personalized Customization
Taking into account the differences among users in terms of process flow, product requirements, and material types, the tire-type mobile crusher for granite provides a highly flexible process configuration scheme. Users can, according to actual situations, choose the single-machine operation mode to complete simple material crushing tasks. They can also carry out multi-machine joint operations by organically combining equipment such as feeders, crushers, vibrating screens, and conveyors to build a complete and powerful crushing operation pipeline, meeting complex and diverse processing requirements. For example, in the production of construction aggregates, the equipment combination and parameter settings can be adjusted according to different requirements for the particle size and shape of the aggregates, so as to produce high-quality construction sand and stones. This personalized customization service enables the equipment to better adapt to various application scenarios.
4. Environmental Protection, Energy Conservation and Green Production
The tire-type mobile crusher for granite adopts an optimally designed power system and energy-saving technologies, which greatly reduces fuel consumption. Compared with traditional equipment, the fuel savings rate is as high as 25%. This not only reduces operating costs but also decreases carbon emissions. In addition, the perfect dust removal system can effectively collect the dust generated during the crushing process, reducing pollution to the air environment and providing strong support for creating a green and environmentally friendly production environment.
