The 1000â?? high temperature calcium silicate insulation board is composed of hard calcium silicate carbohydrate and reinforced fiber, does not contain asbestos, the highest heat resistance temperature of 1050, is an efficient energy-saving product. With high heat resistance temperature, strong heat insulation performance, low volume weight, high strength, good durability, corrosion resistance, cutting, sawing and other excellent construction characteristics, can be widely used in kiln energy saving and heat preservation projects. Applicable to steel, petrochemical, ceramics, glass, cement, external wall insulation and all kinds of furnace insulation, and electric power, machinery, electronics, shipbuilding and other industries of thermal insulation. Calcium silicate is a common alternative to asbestos as a safe insulation material. Calcium silicate is one of the most widely used materials for fire prevention in Europe. Europeans are more inclined to use calcium silicate as cladding. In smelting metal ores, silica reacts with calcium carbonate to form this substance to form slag. 1050 degree high temperature resistant calcium silicate board has: 1. Good durability, can withstand the continuous heat load within the high temperature limit. 2. Low thermal conductivity and high adiabatic performance throughout the use range. 3. Light weight, high specific strength. 4. Good durability, long-term use without powder phenomenon. 5. Strong construction applicability, with ordinary woodworking tools can be cut products at will. 6. Safe and hygienic use. Free of asbestos, sulfur, chlorine and other toxic substances. 7. Not afraid of wet water, product performance unchanged after drying. 8. Protect high temperature equipment and extend the service life of equipment
Sodium gluconate can be used as high-efficiency chelating agent in construction,textile printing and dyeing, metal surface treatment and water treatment industries, steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring � in electroplating industry, and high-efficiency retarder in the concrete industry. Industrial sodium gluconate used as concrete admixture has the following advantages: 1. With sodium gluconate, the W/C ratio can be reduced, which can increase the strength of concrete. This is a high-quality concrete. 2. It is difficult to construct large blocks and heavy weight. Due to the addition of sodium gluconate, the improvement of concrete workability and the delay of setting time can avoid the formation of joints on the structure, and as a result, the structural strength can be improved. 3. It is of great significance to keep the W/C ratio constant and improve workability in hot areas. A large amount of sodium gluconate was used when building bridges in the Middle East. 4. Adding sodium gluconate to the concrete mixture can delay the setting time, which is very important for long and difficult perfusion. 5. In the modern concrete industry, ready-mixed concrete is prepared at a central location and then transported by mixer truck. In this case, it is very important to increase workability and initial setting time. 6. Lowering the W/C ratio can make concrete with higher strength and durability. Sodium gluconate can achieve this goal. This is very important for high-strength reinforced concrete. 7. The prefabricated mortar for masonry must be usable for a long time. Adding sodium gluconate can extend the working period. 8. Oil well grouting grout is difficult to operate due to the high temperature, but after adding sodium gluconate, the concrete can work at 170 for several hours.
Overflow Type Ball Mill Overflow Type Ball Mill Overview: The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding. Overflow Type Ball Mill Features: 1. The jack-up device of wet grate ball mill makes maintenance easy. 2. The hydrostatic and hydrodynamic bearings ensure the smooth operation of wet grate ball mill. 3. The low speed transmission of wet grate ball mill contributes to easy overhaul and maintenance. 4. The oil-mist lubrication device guarantees reliable performance of bearings. 5. The gas clutch adopts the flexible start-up model. Working Principle : Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder. Due to the continuously feeding materials, the pressure pushes materials to the outlet and the grinded materials are discharged from the cylinder outlet. Qualified materials flow from the cylinder outlet. In wet grinding, the materials are taken out by the water flow. There are backpitch impellers in the hollow shaft, which can make the balls and coarse ores in the overflow return to the mill. With simple structure, higher operation rate, and rolling bearing, the energy conservation is significant.
Spiral Sand Washer Spiral sand washer is widely used in the washing of materials in the sand and gravel plant, mining, construction materials, communication, chemical, hydropower, concrete mixing plant, etc. It can efficiently clean the sand, taking away the impurities adhered to the sand and breaking the vapor coatings around the sand particles to facilitate dehydration. It is applied to sand and gravel plant, construction sites, hydropower plant dams, glass making, and development of oil well, etc. Spiral Sand Washer Features: 1.Reliable drive system, high capacity and low energy consumption; 2.Simple and good seal structure, stable performance and convenient operation; 3.A wide range of applications, suitable for cleaning various sizes of materials 4.The finished product has a high degree of cleanliness, extremely low content of mud and stone powder; 5.The spiral blade is made of cast steel with high wear-resistance and long service life. Working Principle : When operating, the motor drives the impeller slowly rotating through the V-belt and reducer. The sand is put into the washing tank through the feeding chute, and rolls over by the impellter driving. During the rolling, the friction between the sand particles strips the impurities, and breaks the vapor coatings around the particles in order to facilitate dehydration. Meanwhile, massive water is put into the washing tank to form a strong water stream to take the impurities and small percentage of foreign matters away immediately and discharge them from the overflow port. The clean sand is taken by the impeller, and finally puts into the discharge groove, finishing the whole washing process.
Single Cylinder Hydraulic Crusher Single cylinder hydraulic cone crusher is widely used in mining, metallurgy,construction, highway, railroad, and waterconservancy, etc. It can break or crush all kinds of medium hard or harder ore for mining, chemical building, materials and other industrial sectors. This kind of machine has the features of big crushing ratio, continuous operating, even granularity, automated hydraulic clearing system, high capacity, simple structure and low operating cost, suited perfectly for middle and fine crushing. Crushing Features: 1.Higher rotating speed and stroke make production capacity which improved 35%-60% than old spring cone crusher; 2.The Max feed size is bigger than other kinds of cone crushers; 3.Better shape of final product than spring cone crusher. Less Needle flake; 4.The design of hydraulic protection and hydraulic cavity clearing improves the automation and reduces the downtime and maintenance time; 5.Auto system of thin oil lubrication makes the life time increased. Working Principle : When the crusher works, the motor drives the small gear; the small gear drives the large gear; the large gear assembly (large gear, large gear rack) drives the eccentric bushing assembly (eccentric steel bush and eccentric bronze bush) and main shaft assembly (main shaft, inner cone, inner cone liner) to revolute within the bronze bush with the center of theoretical verticlal line, while the main shaft assembly can rotate around the main shaft within the eccentric bronze bush as the center line. When the crusher works without load, the eccentric bushing assembly and the main shaft assembly revolutes the large gear. When the materials fall into the crushing cavity, the main shaft assembly (main shaft, inner cone) slowly rotates within the eccentric bronze under the resistance of materials.
