Mineral powder sand washer

Quartz sand dryer is mainly used for drying materials with certain humidity and particle size range, and is widely used for drying materials that are not afraid of high temperature and slightly polluted by st, such as building materials, metallurgy, chemical instry, cement instry, various quartz sand, mineral powder, limestone, pulverized coal, quartz sand, clay, yellow sand, foundry sand, scrubbing sand, various metal concentrates, tailings, etc. According to different drying materials, the length diameter ratio, power and weight of the equipment will change

working principle of Jinhua Machinery quartz sand dryer:
quartz sand is sent to the hopper by belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe through the hopper feeder. The inclination of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line. When the material is added from the higher end, the heat carrier enters from the lower end and contacts with the material in a counter current, and the heat carrier and the material flow into the cylinder in parallel. With the rotation of the cylinder, the material moves to the lower end under the action of gravity
when the wet material moves forward in the cylinder, it is directly or indirectly heated by the heat carrier to dry the wet material, and then it is sent out by the belt conveyor or screw conveyor at the discharge end. The inner wall of the cylinder is equipped with a board, which is used to and scatter the material, so as to increase the contact surface between the material and the air flow, so as to improve the drying rate and promote the material forward. The heat carrier is generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, the cyclone st collector is generally required to capture the materials in the gas. If it is necessary to further rece the st content of tail gas, it should be discharged after the bag filter or wet filter

7. The dryer adopts "self-aligning supporting roller device", which makes the supporting roller and rolling ring always in linear contact, thus greatly recing the wear and power loss
8. The particle size and moisture content of the proct can be controlled according to the user's requirements. When drying the slime, the moisture content of the proct can reach below 8%, and the particle size can be controlled below 8 mm

Function:

adding appropriate amount of mineral powder can improve the fluidity of concrete, rece the hydration heat of cement, improve the impermeability of concrete, improve the strength of concrete in the later stage, improve the internal structure of concrete, and improve the impermeability and corrosion resistance. The concrete mixed with ground mineral powder can delay the hydration rate of cementitious materials and prolong the setting time of concrete, which is beneficial to the transportation and construction of concrete in high temperature season

mineral powder is a kind of high fineness and high activity powder obtained from water quenched blast furnace slag after drying, grinding and other processes. It is a high-quality concrete admixture and cement mixture, and is recognized as an important material for preparing high-performance concrete in the world. The use of granulated blast furnace slag powder can effectively improve the compressive strength of concrete and rece the cost of concrete

extended data:

Application of mineral powder:

1. Save 30-60% of cement consumption (including cement mortar), rece the cost of cement and concrete engineering

Slag powder is also known as ore powder, granulated blast furnace slag powder. The mineral powder proced in China is mainly used as concrete admixture. It is proced by professional factories and added into concrete when making concrete. The amount of mineral powder is based on the quality of cement in concrete. Generally, gypsum can also be added in the proction of mineral powder, which is 2% based on SO3%
ore powder can be further divided into ordinary ore powder and ultra-fine ore powder. It is distinguished by specific surface area
mineral powder is a kind of high fineness and high activity powder obtained from water quenched blast furnace slag after drying, grinding and other processes. It is a high-quality concrete admixture and cement mixture, and is recognized as an important material for preparing high-performance concrete in the world. The use of granulated blast furnace slag powder can effectively improve the compressive strength of concrete and rece the cost of concrete. At the same time, it can restrain the alkali aggregate reaction, rece the hydration heat, rece the early temperature cracks of concrete structure, improve the compactness of concrete, and improve the anti permeability and anti erosion ability. According to the national standard GB / T18046-2000, the ore powder is divided into three grades: S105, S95 and S75, and the content of inorganic substances such as active calcium, silicon and aluminum is more than 30%
superfine slag powder can not only rece the cost of 8-13 yuan per cubic meter of concrete, but also make the concrete have good mechanical properties, small and delayed hydration temperature peak, good volume stability and so on< The results show that: 1. Save 30-60% of cement (including cement mortar), rece the cost of cement and concrete engineering. 2. It has the function of pozzolanic to increase the compressive, tensile, bending and shear strength of concrete. 3. Significantly rece the hydration heat of concrete, improve the workability of concrete, rece segregation and bleeding, rece the temperature difference and internal stress of mass concrete, and restrain the cracks caused by temperature difference. 4. It can inhibit the alkali aggregate reaction, and significantly improve the ability of concrete to resist alkali aggregate reaction. 5. It can exist in concrete in the form of micro aggregate, improve the pore structure of concrete, refine and homogenize the pore size, and improve the impermeability, freeze-thaw resistance and rability of concrete. 6. It can significantly rece the bleeding of cement concrete and improve the workability of cement concrete. 7. It can effectively improve the corrosion resistance of cement concrete to seawater and fresh water, and resist sulfate corrosion. It is especially suitable for anti seawater engineering, underground engineering and pavement engineering. 8. Under the condition of constant water consumption, plastic concrete can be prepared to avoid quality problems caused by dense reinforcement and poor vibration. Under the same condition, it can make the concrete flow into the mold, rece the abrasion of concrete pump body, pipe and mold, and prolong its service life. 9. It can prepare masonry, plastering cement mortar and low-grade cement. In the case of meeting the strength requirements, it can not only save 30-60% of the cement, but also improve the construction operability. 10. It is suitable for making environmentally compatible cement-based materials and admixtures for high performance concrete
