The ore dressing test includes the following parts:
1) Raw ore analysis: including chemical analysis and total spectrum analysis of the target elements of the ore,
2) identification of rock and minerals and phase analysis: determination of the physical and chemical presence of minerals (selective items),
3) X-ray diffraction analysis: determination of mineral composition (selectivity project),
4) mineral exploration exploration test: used to initially determine the mineral selectivity, preliminary determination of the concentrate content and approximate recovery rate of the target element through experiments,
5) ore dressing conditions experiment On the basis of exploratory experiment, each part of the beneficiation test is adjusted and optimized to obtain accurate and optimal beneficiation test conditions, including grinding fineness, pharmaceutical system, rough sweeping times, etc. (optional items),
6) According to the beneficiation test, the appropriate recommended process is issued.
7) According to the recommended process, refer to the processing volume of the customer's demand, and give a complete set of equipment selection configuration.
1. Equipment selection: In the case of determining the beneficiation process, combined with the beneficiation test and the processing volume of the customer's demand, the equipment selection of the main equipment of each section is carried out. Equipment selection includes selection of equipment types and selection of equipment models.
1) The choice of equipment type is based on the nature of the ore and the demand and price of the upper and lower connection equipment. Considering the factors, the most suitable equipment can be selected if the requirements are met.
2) In the case of the selected equipment type, according to the mineral processing volume, mineral properties, comprehensive consideration of the cyclic return amount, amplification factor and other factors in the corresponding stage, through calculation, select the appropriate equipment model and quantity.
2. Engineering design: In the case that the beneficiation process and equipment selection have been determined, the project layout map of the production line equipment is issued to the customer site inspection site or according to the site drawings provided by the customer.
1) The layout of the project needs to comprehensively consider the factors such as the site drop on the site, reasonably arrange the location and material direction of the equipment, and assist the connection equipment.
2) The engineering drawings need to include the single ground map of each specific equipment and the relative position of the foundation. Line drawing, side view, waterway diagram, etc.
In the case of equipment selection, mine design and equipment manufacturing can be carried out simultaneously, which greatly shortens the construction period and saves the construction period cost for customers. In order to strictly control the construction period, detailed and feasible project schedules will be formulated in the equipment manufacturing process, and the project control team will strictly supervise the work progress.
A good installation team guarantees the smooth installation of our site and assists customers in commissioning and production.
The raw ore samples used in the beneficiation test are crushed and shrunk, and the test samples are prepared, and the test samples are retained, and the samples are compared.
Determination of the nature of the ore. Including: the determination of the target material composition of the ore and the physical and chemical properties of the ore; the content includes chemical analysis, total spectrum analysis, rock and mineral identification, phase analysis, etc. (the above items are optional).
Based on the experience, the preliminary mineral processing technology exploration test is carried out to determine the mineral selectivity. The concentrate grade and approximate recovery rate of the target element are determined experimentally.
On the basis of the exploration test, each part of the beneficiation test was adjusted and optimized to obtain accurate and superior ore dressing test conditions, including grinding fineness, pharmaceutical system, and number of rough sweeps.
According to the beneficiation test, the final ore dressing conclusion is given and a suitable recommended process is issued.
According to the recommended beneficiation process, refer to the processing volume of customer demand, give a full set of equipment selection configuration
1) Division of the scale of the ore dressing plant, work system, process design, selection and calculation of main process equipment, calculation and modeling of auxiliary equipment and facilities, and general layout.
2) Construction drawing design: Supplement the problems existing in the preliminary design, including the required topography, hydrology, engineering geology, etc., main equipment order implementation, water supply, power supply, external transportation, etc., on every aspect of the plant selection Draw a lot of construction drawings.
Our company has formed a complete and strict quality management system in equipment manufacturing. In the production process, we strictly control the procurement and quality control, and the goods are purchased in the process of material procurement, ensuring excellent quality of raw materials. At the same time, each finished product produced in the workshop is fully inspected and pre-accepted, and all projects are tested. At present, it can produce more than 600 kinds of equipment for mining, selection and smelting, and provide a full set of main and auxiliary equipment for mine production below 10,000 tons/day.
The production plant has more than 200 skilled mineral processing equipment manufacturing workers, which can produce almost all mineral processing equipment.
Equipment installation, including crusher, sieve, ball mill, classifier, flotation machine, concentrator, filter and auxiliary equipment, etc. They are strictly checked and inspected to ensure high speed, speed and no damage during transportation. Regardless of the storm, delivery on time, to eliminate the time cost of wasting customers.
The process of equipment installation is generally as follows: Building inspection → main equipment installation → platform installation → civil engineering installation → auxiliary equipment installation → non-standard parts installation → electrical equipment installation → pipeline equipment installation → automatic installation → cable line installation → on-site commissioning → inspection confirmation.
1) Equipment commissioning
All equipment, cable lines, pipelines, etc. are tested and operated, and empty vehicles are run to test with water, and all aspects of the equipment are tested. Process debugging is a re-adjustment of the previous process.
2) Process debugging
Since most of the beneficiation experiments are carried out in the laboratory, there will be some discrepancies with the actual plant operation. For this reason, we will organize the technicians to continuously debug the process, and strive to adjust to the best process to solve the various mismatched problems in the “ideal transformation reality”.
For example, whether the amount of crushing matches the processing volume of the ball mill, whether the dust removal process and equipment meet the requirements of the working environment; the wear of the liner of the ball mill, the ratio of the steel ball, etc.; the thickness of the flotation machine and the precise control of the medicament will also be The impact, only after debugging, can maintain the efficiency and stability of the flotation machine. The debugging process can be said to be an important task to ensure efficient output and long-term operation of the mine.
