200 TPH stone crushing plant

Introduction

The stone crushing plant is for complete production line such as limestone, granite, river stone, basalt and so on to product aggregates for ready mix concrete, building material, construction site and others.

Stone crushing plants can be equipped with gyratory crushers, jaw crushers, impact crusher or cone crusher depending on material properties and required capacities.

Deya Machinery is able to provide mobile, modular, or stationary stone crushing plants and work together with our clients to choose the most suitable machine type depending on the mineral deposit, mine plan and mining method.

Equipment in details

1. Bridge wall

It provides rigidity to travel stone ground level to hopper level. Fully mobile crushing plants are directly fed by shovel or wheel loader and no haulage trucks are required.

2. Primary hopper

It is for materials loading via the bridge wall. Typically are installed by height difference in the working site.

The hopper can be designed and produced in Deya Machinery’s workshop, while delivered by pieces, and assemble in the working site by screws and bolts, only need a little work for welding in the working site, for the reinforcement of the hopper.

5. Stockpile

In order to improve the operation rate of large scale stone crushing plant, intermediate stockpile is often set up between the initial crushing stage and the secondary crushing stage, which can store a considerable amount of materials and divide the whole system into two sections.

Advantages of intermediate stockpile as follows:

1. When the front section equipment cannot operate normally due to mine reasons, transportation reasons or maintenance equipment, etc., the back section equipment can operate normally for several hours or even days by relying on the stock material in the intermediate stockpile.

2. It can also be separated from the operating time, usually the initial crushing stage has larger capacity due to the larger feeding size, production time does not have to be too long to meet the daily output, while subsequent equipment does not have to be configured too large, it can increase the daily operation time, so that the existence of the intermediate stockpile has the potential to make the front and rear section using different operating hours.

Intermediate material stockpile has various structural forms, the common form is to use the surface pile material, excavate the underground channel, and use feeder and belt conveyor to convey the material out from underground. Restricted by terrain, investment, etc., it is generally more appropriate to store 1~2 days of production.
