50-80TPH Alluvial Diamond Washing Processing In Angola

The customer’s requirement is to clean the raw ore, remove waste stones, and then sort the diamonds in a centralized manner; with our own engineers, we mainly provide detailed factory layout drawings and each machine drawing to help with installation. Based on Angola’s customer requirements and ore conditions, JXSC designed and provided a complete set of impact diamond washing and processing plant machines and all accessories, with a processing capacity of 50-80TPH.
The main equipment includes vibrating feeder + trommel scrubber + belt conveyor + high-frequency vibrating screen + jig separators + water pump. The specific details are as follows:

1. Customers can use wheel loaders or excavators to feed raw ore into the vibrating feeder (with a 75mm gap), which can remove +75mm of waste rock to the ground. Water needs to be sprayed on the vibrating feeder so that materials of 0-75mm can enter the drum washer more smoothly. While removing oversized stones, the raw ore is evenly fed into the drum washing machine.

2. The 0-75mm material enters the trommel scrubber for washing, and the screen size is 25mm to release diamonds from the clay. After cleaning, +25mm waste gravel will be screened out, and the discharged 0-25mm material will flow to the high-frequency vibrating screen.

3. The high-frequency vibrating screen uses 2mm & 8mm PU screen mesh, and high-pressure water is sprayed on the screen mesh; this can clean 2-25mm more cleanly and remove 0-2mm muddy water at the same time. Then, materials in two size ranges of 2-8mm and 8-25mm are obtained and fed into two different jig separators.

4. The jig separators are used to select diamonds. The 2-8mm and 8-25mm materials will be fed into two jigs respectively, so the concentration effect will be better. Diamond concentrate is obtained from the jig.

Note: If you require a higher purity diamond, individual diamonds can be sorted by hand or with an X-ray sorter. JXSC supports customizing complete sets of diamond processing equipment and solutions to achieve high recovery rates, contact us to get a quote!
