The difference between skid-mounted crusher and mobile crusher

There are significant differences between skid-mounted crushers and mobile crushers in several aspects. Here is a detailed comparison of these two crushers:

1、Definition and classification
Skid mounted crusher
The skid-mounted crusher is actually a type of semi-mobile crushing station, also known as a modular unit.
It places the machine body at a suitable working level in the open-pit stope, and uses a crawler transport vehicle or other traction (pull) equipment to move the crushing unit as a whole (or separately) as the working steps advance and extend.
mobile crusher
The mobile crusher is a mobile equipment that integrates feeding, crushing and conveying.
It can adjust its position at any time as the working surface moves in the stope, and has various walking modes, including crawler type, tire type (also walking type).

2、Structural characteristics
Skid mounted crusher
It usually consists of equipment such as crushing, screening or feeders, as well as non-standard design and production parts such as steel structure brackets, hoppers, and buffer silos, and standardized design and production parts such as steel grating platforms, italics, and handrails.
The most typical feature is that it is connected to the ground without a concrete foundation. Its service life ranges from several months to several years, and its one migration time usually does not exceed 48 hours.
mobile crusher
The structure is relatively compact and integrates feeding, crushing and conveying functions.
The crushing system usually consists of a crushing chamber, a breaker hammer and a crushing plate. The breaker hammer impacts, impacts and crushes the raw materials in a high-speed rotating manner, while the crushing plate plays a role in guiding and controlling the particle size of the material.

3、Working principle
Skid mounted crusher
The working principle is similar to that of a common crusher. Materials are crushed through the crushing equipment.
Since it is semi-mobile, it needs to be moved at different stages of the operation.
mobile crusher
Feeding: The raw materials are fed into the feeding port of the mobile crusher through loading equipment such as loaders or excavators.
Crushing: After the raw materials enter the crushing cavity, the crushing system starts to work, impacting, impacting and crushing the raw materials.
Screening: The crushed materials are further screened through devices such as conveyor belts or vibrating screening machines.
Conveying: The screened materials are transported to the next process link or storage area through equipment such as conveyor belts or stackers.
Control: Mobile crushers are usually equipped with a control system to monitor and control the operating status and working parameters of the equipment.

4、Application Scenarios, Advantages and Disadvantages
Skid mounted crusher
Application scenario: It is usually placed on the working side of the stope and the ore transport distance is less than 3km.
Advantages: It not only has the advantage of being mobile, but also overcomes the disadvantage of long time for semi-fixed website establishment and relocation. The overall design and supply save time and effort, and the construction and installation are fast and efficient. The construction period is short, which is conducive to rapid construction and production. The investment is more reasonable, there is less civil construction work, no concrete construction is required above the ground, and the labor intensity is low.
Disadvantages: Special migration tools are required for migration, and there may be some complexity during the migration process.
mobile crusher
Application scenario: It is generally located on the mining working face and needs to move flexibly as the mining working face advances. It is suitable for large-scale and continuous mining processes, especially in large-scale open-pit mines.
Advantages: It replaces dump trucks and reduces procurement costs; reduces transportation costs by 50% to 70%; reduces spare parts costs; reduces labor costs; reduces stope road maintenance; and is both safe and environmentally friendly.
Disadvantages: The equipment is complex, expensive, and the one-time investment is too large, making it economically unbearable for mines.
To sum up, there are significant differences between skid-mounted crushers and mobile crushers in terms of definition, structural characteristics, working principles, application scenarios, advantages and disadvantages. The choice of crusher depends on specific mine conditions, mining needs and economic considerations.
