500 T/H Granite crushing plant delivered to UZ successfully

The 500tph granite crushing plant mainly consists of crushing system, screening system, sand making system, storage and shipping system and dust removal system. Full set of  500 t/h stone crushing plant machines were delivered to Uzbekistan. The machines are loaded to truck one by one to clients site. This is a large scale stone crushing & screening and sad making plant including 2 set crushing equipment. Main configuration of this granite crushing plant is below:
2 sets vibrating feeder
2 sets primary jaw crusher
2 set cone crusher
1 set impact crusher
1 set VSI sand making machine
4 set vibrating screen
1 set screw sand washing machine
1 set sand dewatering screen machine

Granite is the main component of Continental crust, which is a kind of magmatic rock formed by magma condensation under the surface. Due to its high hardness and wear resistance, it is a good material for high-end building decoration projects. We designed a complete hard stone crushing plant solution for client. Now we will summarizes the main design points of this stone crushing system.

1.Key points in the design of the unloading bin

The vibrating feeder is arranged outside the bottom of the discharge bin.

Advantages:

The granite materials in the warehouse are not directly pressed on the vibrating feeder, the equipment requirement are lower, and the manufacturing cost is correspondingly smaller;

Disadvantages:

When the material contains a lot of soil or has poor fluidity, it is easy to block the material or the discharge is not smooth.

2. Crushing equipment selection principles

The crushing system is mainly composed of coarse crushing, medium crushing and fine crushing (shaping). Based on the characteristics of granite, product particle shape and market demand, it is decided to adopt a jaw crusher + cone crusher + vertical shaft crusher (sand making machine) system. , its process is basically the same as the jaw crusher + cone crusher system, with the addition of a vertical shaft crusher to reshape the aggregate to meet customer needs for high-quality aggregate.

Advantage:

2-1 The proportion of product varieties is easy to adjust;
2-2 Suitable for materials with high abrasion index;
2-3 The product has good particle shape, small amount of fine powder, and high acquisition rate of coarse-grained aggregates;
2-4 The crusher requires small dust collection air volume;
2-5 Low energy consumption per unit product and low consumption of wear parts.
2-6 The vertical shaft crusher produces more fine powder and can produce machine-made sand;

Shortcoming:

2-7 When the system capacity requirements are large, three-stage crushing or more crushers are required. At this time, the process is complicated and the project investment is high;
2-8 Its application range is relatively narrower than that of impact crusher.

3. Buffer pile or buffer bin setting (before primary crushing)

Design a screening mixing tunnel before the primary crushing of the aggregate production line, so that the fine materials and soil that do not need to be crushed can be screened out, and then the soil and fine aggregate can be screened out through the vibrating screen, which can prevent the fine materials from being broken again. By increasing energy consumption and powder materials, soil can be removed to reduce dust in subsequent processes, and the quality of aggregates can also be improved.

4. Buffer pile or buffer bin settings (between crushing)

A semi-finished material pile is designed between the primary crushing and secondary and fine crushing of the aggregate production line. The functions of this semi-finished material pile are:
4-1. It can balance the overall system capacity of the aggregate production line. There is no need to consider the fluctuation coefficient of the primary crusher when selecting the specifications of the medium and fine crushers;
4-2. If the primary crushing workshop is under maintenance, the downstream aggregate making workshop can continue production;
4-3. For safety reasons, most mines only mine during the day shift. The downstream aggregate processing workshop can still produce in two shifts to flexibly meet market demand. In addition, the number of equipment in the downstream aggregate processing workshop can be reduced by half or selected. Equipment with small production capacity is matched with the upstream (because the semi-finished product pile can flexibly adjust the system capacity), which can accordingly reduce system investment.

This 500tph crushing production line has been activated normally on the client and is currently running well. If you need to know the detailed crushing production line configuration plan and price, please feel free to contact us.
