Crushing equipment is inseparable for the production of open-pit mines. The use of suitable crushing stations can effectively improve production efficiency. According to the degree of fixation between the crushing equipment and the foundation, the surface crushing stations of open-pit mines are divided into mobile and fixed types. This article analyzes and compares the classification of these two crushing stations and their advantages and disadvantages, hoping to bring some help to your choice.

Mobile crushing station

Generally, it integrates feeding, crushing and conveying. The walking adopts crawler type or tire type (also has stepping type), and the position can be adjusted at any time in the site with the movement of the working surface.

Advantages of mobile crushing station

Replacing dump trucks, reducing procurement costs;

Reducing transportation costs by 50% to 70%;

Reducing spare parts costs; reducing labor costs;

Reducing working site road maintenance;

Safety and environmental protection.

Because it is a trinity equipment, and the continuous transportation equipment connected to it is a belt conveyor, the crawler mobile crushing station is suitable for large-scale open-pit mine applications and is suitable for large-scale, continuous mining processes.

Disadvantages

The equipment is complex and expensive, and the one-time investment is too large.

Stationary stone crusher plant

The fixed crushing station is usually arranged outside the sit boundary, or set inside the site in conjunction with the chute, and is not affected by the advancement of the site steps, and is connected to the ground with a permanent fixed foundation. It will be used permanently after completion, and will not be removed. The feeding method is diverse, and it can be unloaded directly by a car, or a buffer silo can be provided by the ore discharging device. The fixed crushing station is generally in the crushing workshop of the concentrator, and has the same life span as the mine.

Disadvantages

The biggest disadvantage is that the ore transportation distance is long, the transportation cost is large, and it is not suitable for reasonable adjustment.

Comprehensive analysis

A. The mobile stone crushing station is self-driving in terms of its walking capacity. Typical walking methods are tire, crawler, and stepping. In terms of deployment position, it is generally located on the work surface of the working site and it can moves flexible as the mining surface advances. The fixed stone crusher plant is the least controversial in classification. It has a solid foundation and is used for a long time outside the site. The transportation distance is relatively strong and is not easy to be adjusted.
