The technical characteristics of the hoist developed by Luokuang are as follows: ▲ Various types of drums, such as integral drum, two-disc drum and four-disc drum, are adopted; ▲ The drum rope groove adopts spiral rope groove, broken line rope groove or spiral rope groove pressed by wood lining and plastic lining, and there is a wire rope transition device between ropes; ▲ The rear cylinder disc brake is adopted, and the electro-hydraulic combined control is adopted; There are two kinds of hydraulic stations: medium-low pressure and medium-high pressure. There are two types of low-pressure hydraulic stations: constant braking force, electrical delay and hydraulic delay. The medium and high pressure hydraulic station has two forms: constant deceleration and constant braking torque. The hydraulic station can be equipped with pressure sensor and pressure relay; ▲ The spindle and the drum are connected by plane high torque friction; ▲ The signal monitoring device consisting of photoelectric encoder, synchro and low-speed Chilean tachogenerator has perfect monitoring and protection functions such as overspeed, overwinding, failure of depth indication, brake shoe wear and spring fatigue; ▲ The console has two forms: integrated signal lamp, reliable electrical instrument and new integrated operating handle, digital depth indicator and depth indicator system integrating digital and lead screw depth indicator, and industrial TV, computer, printer and other special countertops. ▲ The crown block device adopts integral or Shuang Ye welded structure, supported by rolling bearings, and the rim is equipped with PVC or nylon friction pads; ▲ It can be equipped with network control and diagnosis system of mine hoist. The coal preparation plant is mainly engaged in the design and research of coal preparation and mineral processing equipment, steel slag treatment equipment and non-standard products; And the engineering process design and development research of coal preparation plant, concentrator and steel slag treatment production line. The product design and research of washing equipment is one of the professional directions of the company. The flotation, gravity separation, screening and dewatering equipment developed can meet the requirements of concentrator, coal washing plant and chemical industry with chemical corrosion. Ore washing equipment includes: ore washer, filter, flotation machine, classifier, magnetic separator, sand washer, thickener, centrifuge, vibrating screen, feeder, conveyor, etc.
▲ Vertical disc filter: GPL and GLL series high-efficiency vertical disc filters used in alumina industry have obtained many patents, and more than 100 sets have been used on site, reaching the international advanced level. This product is being extended to industries such as nonferrous metals, ferrous metals, chemical industry and coal to replace old filters and filter presses such as GP, PG and GPY. At the same time, the developed pressure filter will also be put on the market to meet the requirements of high fineness and low moisture dehydration. ▲ Centrifugal dehydrator: TWZ series horizontal vibrating centrifugal dehydrator and LL series vertical spiral scraper discharging centrifugal dehydrator, developed for dewatering coal or granular materials, used domestically and exported to South Korea; TC sedimentation and TCL sedimentation filtration series centrifugal dehydrators are developed for dewatering coal slime and various powdery materials, and hundreds of them are also used in China. ▲ Double-end air inlet rotary dryer: According to the technology of French K-T company, the patented SZG series double-end air inlet rotary dryer and coating drum have been applied to porous granular ammonium nitrate projects in Yunnan Yunfeng, Shaanxi Xinghua, Guangxi Liuyi and other fertilizer plants. ▲ Steel slag treatment project and host equipment: Steel slag treatment is an important measure for comprehensive utilization of waste in steel mills and improving economic benefits. Nearly ten steel slag treatment projects have been completed in Hangzhou Iron and Steel Group, Tangshan Iron and Steel Group and Karachi Iron and Steel Group, Pakistan, and its main equipment, PEY series hydraulic jaw crusher and PYY series hydraulic cone, has served many domestic steel mills and charging plants.
