Sichuan Shimian Mine Concentrator
Asbestos mine in Sichuan Province County, built a roughing station and three beneficiation plants. The ore mined in the underground is crushed by the roughing station-hand selection-screening process. After pre-concentration, it is supplied to the first and second concentrating plants, and the open-pit mining ore is directly supplied to the third concentrating plant. The design capacity of the mine is 15000t/a, the mine has a grain size of 500mm, the ore grade is 1.38%, and the ore water is 5.08%. The size of the ore in the selected workshop is 50mm, the selected grade is 2.42%, and the moisture in the selection is 2.00%. The grade of tailings is 0.5%, the grade of tailings is 0.31%, the recovery rate of ore is 90.31%, and the yield of Grade IV or above is 15.19%.
PC plastic,full name Polycarbonate.
PC plastic is a kind of excellent comprehensive performance engineering plastics.It has excellent physical, mechanical, electrical, and thermal properties,so it's known as the "king of the transparent plastic'
Classification:
Anti - static PC SHEET, conductive PC SHEET,fireproof PC SHEET,PC fiber - resistant, PC GF SHEET, PC+ABS SHEET,anti-ultraviolet ray resistance PC, food grade PC, anti - chemical PC.
Advantages:
1,Light weight
2,Impact resistance
3,Excellent physical, mechanical, electrical and thermal properties
4,Ultraviolet resistance
Disadvantages:
Polycarbonate is not resistant to ultraviolet light, no resistance to alkali, resistance to hydrolysis stability is not high, is the main performance defect is sensitive to the gap, resistance to organic chemistry, scratch resistance is poorer, long-term exposure to ultraviolet light yellow, are vulnerable to the erosion of some organic solvents.
Applications:
1. Dust-free room spacer
2. Equipment shield and test fixtures;
3. Commercial Building Lighting;
4. Soundproof walls;
5. Greenhouse;
6. Components for medical and pharmaceutical devices;
7. Face shields;
8. Skylights, etc
Modified use:
The purpose of the modified PC Plastic is to toughen, improve the processing performance, reduce the residual deformation, and increase the flame retardancy, etc.
PC/ABS can improve bending modulus, heat resistance and plating performance.
PC/PET and PBT can improve drug resistance and solvent resistance.
PC/PMMA added plexiglass to enhance the appearance of pearlescent color.
PC/PA and HIPS can improve impact toughness and surface finish.
PC/HDPE can improve water resistance, aging resistance, weather resistance and LDPE.
The PC Plastic USES fiberglass or carbon fiber to enhance modification and improve mechanical strength.
The flame retardant grade PC Plastic can be made with bromine flame retardant and antimony trioxide.
Other and polysulfone, aromatic polycarbonate, polyvinyl formaldehyde, polypropylene, polystyrene can be modified to achieve the balance between economy and performance.
Combustion characteristics:
Combustion condition: easy, softening foaming
Flame status: small amount of black smoke
After the fire: out of the fire
Bouquet: no special taste
Specification: the thickness of PC Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
Color: Black and clear, can also be made another color, and the color order is 500KG.
Modified varieties:PC Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.

The length of the asbestos fiber in the ore is 0.5~10mm, the maximum size of the underground ore is 400mm, the moisture is 4%~6%, and the grade is 1.0%~2.5%.
The process and equipment of the three concentrators of the mine are basically the same, and the process flow of the second workshop of the first plant is shown in the following figure. In the process, the three-stage crushing and uncovering cotton is used, and the impact crusher , the vertical shaft hammer crusher and the cage crusher are respectively used, and the three-stage sorting adopts the plane rotary sieve and the plane shaking sieve suction selection, and the coarse fine cotton selected in each section is selected. The three streams are divided into hexagonal sieves and small flat sieves for dust removal and sand removal. Drying is carried out using a cylinder dryer. The first stream produces long cotton (Class II), the second stream produces medium long cotton (Class III-IV), and the third stream produces short cotton (Grade V). 
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of 10-180mm is 600*1200 mm. PC Plastic sheet can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.and The diameter of the PC Plastic rod can be produced from 2mm to 250mm, the length is 1 meter, and it can be ordered to be more than 3 meters in length.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.
