Bulk material machinery refers to equipment and machinery used to handle, transport, and process large quantities of materials in bulk form. This can include various types of machinery such as conveyors, feeders, crushers, screens, mixers, and storage systems.

These machines are commonly used in industries such as mining, construction, agriculture, and manufacturing, where large volumes of materials need to be moved, sorted, or processed efficiently. They are designed to handle a wide range of bulk materials, including minerals, ores, grains, chemicals, and construction materials.
Bulk material machinery is typically designed to be robust and durable, capable of handling heavy loads and operating in harsh environments. They are often automated or semi-automated to improve efficiency and reduce labor costs. Additionally, safety features are incorporated to protect workers and prevent accidents.
Valve material awareness and the use of temperature
(A), before the start of the preparation and inspection? The valve body materials are: C carbon steel, I 1Cr5Mo chromium molybdenum steel, H Cr13 stainless steel, K malleable iron, L aluminum, P 0Cr18Ni9 Department of stainless steel PL 00Cr19Ni10 stainless steel, Q ductile iron, R 0Cr12Ni12Mo2 stainless steel, RL 00Cr17Ni14Mo2 stainless steel, S plastic, T copper and copper alloy, Ti titanium and titanium alloy, V chromium molybdenum vanadium steel, Z gray cast iron. The temperature of the valve is determined by the material used to make the valve, and the world's valve network gives you access to the most commonly used materials for the valve. Gray cast iron valve -15 ~ 250 ℃ malleable iron valve -15 ~ 250 ℃ ductile iron valve -30 ~ 350 ℃ high nickel cast iron valve maximum temperature is 400 ℃ carbon steel valve -29 ~ 450 ℃, in JB / T3595-93 standard Recommended temperature t <425 ℃ 1Cr5Mo, the highest temperature of alloy steel valve is 550 ℃ 12Cr1MoVA, the highest temperature of alloy steel valve is 570 ℃ 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti stainless steel valve -196 ~ 600 ℃ copper alloy valve -273 ~ 250 ℃ plastic valve (Nylon) Maximum temperature 100 ℃ Plastic valve (chlorinated polyether) Maximum temperature 100 ℃ Plastic valve (PVC) Maximum temperature 60 ℃ Plastic valve (polychlorotrifluoroethylene) -60 ~ 120 ℃ Plastic valve ( PTFE) -180 ~ 150 ℃ Plastic valve (natural rubber diaphragm valve) Maximum temperature 60 ℃ Plastic valve (nitrile rubber, neoprene diaphragm valve) Maximum temperature 80 ℃ Plastic valve (Viton diaphragm valve) Highest Temperature 200 ℃ valve lining with rubber, plastic, rubber and plastic temperature resistance shall prevail. Ceramic valve, because of its acute temperature degeneration is poor, generally used for working conditions below 150 ℃. Recently there is a super-performance ceramic valve, capable of high temperatures below 1000 ℃. Glass valve. Temperature rapid degeneration, generally used below 90 ℃ working conditions. Enamel valves, temperature resistance by the seal material restrictions, the maximum temperature does not exceed 150 ℃.
