Comparison of several processes for a production line with an annual design capacity of 15 million tons

Hard rock or abrasive materials, such as granite, for a production line whose crushing output is less than 2000t/h, the process of “jaw crusher + cone” is selected. ” process. Most of the above require plastic surgery.

There are application cases for jaw crushing lines with a production capacity of 2000t/h, but not more than 2000t/h.

1. Process flow and main equipment details of “Gyratory + Cone”
Crushing material: granite
Maximum feeding size: 1000m
Product particle size: 0-5mm, 5-10mm, 10-20mm, 20-31.5mm
The annual design output is about 15 million tons of production lines, using the “cycle + cone” process, and the instantaneous output is two 2000t/h production lines.

2. Process flow chart and main equipment details of “jaw crusher + cone”
Crushing material: dolomite
Maximum feeding size: 1500mm
Product particle size: 0-5mm, 5-10mm, 10-20mm, 20-31.5mm
The annual designed production line is about 15 million tons, using the process of “jaw crusher + cone”, and the instantaneous output is two 2000t/h production lines.

Design a high-quality aggregate production line with an annual output of about 15 million tons. For hard rock or abrasive materials, choosing the “jaw crusher + cone” process has the following advantages:
(1) The investment in the first stage of crushing equipment is less, and the investment cost is saved by about 35% compared with the “gyroscope + cone” process;
(2) The equipment installation requirements are low, and the civil construction cost is low, saving about 20%;
(3) Because the maximum feeding particle size of the gyratory crusher is relatively small, the “Gyratory + Cone” process requires an additional investment of about 15 million yuan for the mine’s secondary crushing equipment, and the mine’s secondary crushing cost is about 15 million yuan per year. Jaw crusher + cone” process, this investment is almost negligible;
(4) The “jaw crusher + cone” process has a lower installation height and a larger platform, which can be loaded by multiple vehicles at the same time. Low maintenance cost, many accessories of jaw crusher are exposed outside, easy to observe and easier to maintain;
(5) The soil removal process is relatively simple. The feeder can directly remove the soil, and then use a vibrating screen to separate the soil. If the soil is removed after the cyclone is broken, a large number of sieves and belt conveyors are required, which increases the investment in equipment. /Civil construction investment and floor space.

Hard rock or abrasive materials, such as granite, generally choose the process of “jaw crusher + cone + vertical crusher”, with an annual design capacity of about 15 million tons of production lines, choose two 2000t/h production lines or three 1350t/h production lines Any production line. With such a configuration, the process is simple and smooth, the equipment is easy to use and maintain, the operation rate is high, and the continuous operation time without failure is long.
