Australia 150TPH Limestone Crushing Project

Design Scheme

Material: Limestone

Input Size: 500-600mm

Output Size: Seven kinds of final products

Capacity: 150TPH

Equipment: GZD1100*4200 vibrating feeder; PE750*1060 Jaw Crusher; PF1315 impact crusher; 3YK2160 and 3YK1548 screen

Technological Process

1. Firstly, the big raw materials were put onto the vibrating feeder (GZD1100*4200) by the truck or excavator, then the materials would be put into the cavity of the jaw crusher (PE750*1060) evenly under the stable vibration of vibrating feeder. Due to the reality that the cavity of PE750*1060 can reach 630mm, so the size of 500-600mm can be crushed easily by it. After the crushing of PE750*1060, the size of materials can reach 80-140mm, the first working part was over now.

2. In order to achieve the goal of seven small-sized final products of customers, we had to crush the materials which have been crushed by jaw crusher PE750*1060 again. At this time, we preferred to choose impact crusher as secondary-stage crusher considering the hardness of the crushed stone (limestone). The impact crusher has been very popular among the customers because it has many advantages when crushing medium hard stone, like big capacity, high reduction ratio, uniform final size and so on. Considering it was a crushing line of 150TPH, we intended to choose the model PF1315 impact crusher. The feed size for PF1315 can reach around 200mm, so it can crush the aggregates from the jaw crusher easily.

3. After the primary crushing of jaw crusher and further crushing of impact crusher, the size of the products can basically meet the demands of our customer, but how to classify them was a question ahead of us. And what we needed was some particular screens which can sift these aggregates to different-sized piles. So the vibrating screens with feature of multi-layer, reliable and stable structure, high screening efficiency were used. And we decided to choose the model 3YK2160 and 3YK1548 screen in view of the 150TPH capacity.

4. The materials from the impact crusher were conveyed to the screen 3YK2160 first through belt conveyor, and three kinds of materials were screened out by it at this time (bigger size). Among that, the materials on the uppermost layer of 3YK2160 were then conveyed to 3YK1548 by belt conveyor and then another 4 kinds of materials were screened out finally (smaller size). And the whole working process was finished by now.
