Piling machinery is used for various pile foundations, foundation improvement and reinforcement, underground retaining walls, underground impervious continuous walls and other special foundations and other engineering construction machinery equipment, including rotary drilling and screw drilling rigs, and its function is to bury all kinds of piles in the soil to improve the bearing capacity of the foundation.
Petroleum machinery refers to a complete set of drilling equipment used for oil and natural gas exploration and development. The main engine of the oil rig consists of eight parts, namely the eight major parts of the rig: derrick, crane, traveling block, hook, faucet, drawworks, turntable, mud pump, etc.
Port machinery mainly refers to the quayside cranes of the port, including portal cranes, quay cranes, continuous ship unloaders, mobile ship unloaders, continuous ship loader, as well as container loading and unloading bridges. Port machinery also includes special equipment for the rear yard, such as container palletizers.
The shield tunneling machine is a large-scale tunnel boring machine, specially designed for tunnel construction.
Coal mining machinery belongs to a large category of machinery. Coal mining machinery is a machinery specially used for coal mining. Due to its professional characteristics, it is different from other mining machinery, mainly including coal mining machines, roadheaders, scrapers and so on.
Commonly used machinery for earth-moving machinery construction are: bulldozers, scrapers, excavators, forklifts, and mining dump trucks.
Hoisting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects, and its scope is specified as a lift with a rated lifting capacity greater than or equal to 0.5t.Also refers to cranes with a rated lifting capacity greater than or equal to 1t and a lifting height greater than or equal to 2m and electric hoists with a fixed load-bearing form, etc.There are mainly truck crane cranes, crawler cranes, truck cranes, tower cranes, gantry cranes, bridge cranes, ship cranes, etc.
Cement vertical mill is used for the grinding of cement and other raw materials. The raw materials go down to the center of the grinding disc. The centrifugal force of the grinding disc rotates the raw materials to evenly distribute and spread the raw materials outward to form a material bed with a certain thickness. At the same time, the material is subjected to multiple grinding rollers on the grinding disc and smashed. The rolling compaction is broken, and moves to the outer edge of the grinding disc, and enters the powder separator through the air ring as the gas rises for powder selection, and the particles that meet the requirements enter the dust collection equipment.
The vertical coal mill is used for the grinding of coal raw materials. The coal raw materials go down to the center of the grinding disc, and the coal raw materials are distributed and flattened out evenly by the centrifugal action of the grinding disc to form a material bed with a certain thickness. The crushing of a grinding roller is broken, and moves to the outer edge of the grinding disc, and enters the powder separator through the air ring as the gas rises for powder selection, and the particles that meet the requirements enter the dust collection equipment
The roller press uses two relatively rotating grinding rollers (one is a fixed roller and the other is a movable roller) with the same speed. The raw material enters from the upper feeding port and is crushed by high pressure in the gap between the two rollers.
