MINING AND TUNNELING MACHINERY

KSP_32(33) The KSP-32 Roadheader is a completely up-to-date medium duty machine for cutting hard strata to reduce a share of blasting and drilling operations. The machine is designed to mechanize breaking and loading of the mined rock while driving mine workings in mixed faces with single-axis compressive strength of up to 100 MPa and abrasivity not more than 15 mg with an inclined gradients ±12° and cutting profile from 10 m2 in the finished section and up to 29 m2 in the rock section in mines hazardous on gas (methane) and coal dust. A powerful boom assembly with high arcing and lifting forces enables the machine to cut harder strata. Features * Robust cutting boom powered by a 110 kW air cooled electric motor * Heavy duty cutting head with efficient pick face flushing facility * Telescopic action to allow cutting head to be sumped in with the machine stationary and therefore independent of floor conditions * Center scraper chain conveyer built for abrasive applications with an enlarged throad * Large crawler tracks which are independently operated to give maximum machine maneuverability for working on steep gradients and poor floor conditions * Real floor sprag jack to increase machine stability in adverse cutting conditions * Loading apron performs as a front support * Scraper conveyor and stage loader enable to use the machine with various type of excavated material handling Parameters Ultimate strength of rocks breaking, sñîmp, MPa, min 100 (f=8) Rock abrasivity, mg, max 15 Minimum finished section, m2 11 Maximum  rock section, (at the cutting boom swing), m2           33.8 Gradients of driven working, degrees ±12 Cutting boom swing, mm:    - height 5000  - width                                           6500  - below ground level 200 Cutting boom Type boom with linear-axial cutting head Telescoping travel, mm 650 Rated power of the cutting head electric motor, kW 110 Cutting head    - maximum diameter, mm 1100  - cutting length, mm 640 Pick number, pcs 42 Cutting head rotation frequency, min -1 33 Cutting rate at the max. diameter of the cutting head, m/s 2.0 Feeder Type loading apron with gathering arms Gathering arms gear hydro-mechanical, kinematically uncoupler Swinging of arms, min-1 30 Feeder width, mm, max 3670 Lowering of the feeder lip below ground level, mm. max 170 Lift of the loading apron lip over ground level, mm, min 700 Chassis   crawler type Chassis drives hydro-mechanical, kinematically uncoupled Traveling speed, m/min.:    - working speed (with loading) 1.0  - maneuvering speed (without loading) 5.0 Track width, mm 550 Maximum traction force of one track, kN 250 Scraper conveyor Type scraper twin-chain with a rigid or lift and swivel stand   twin-motor electromechanical gear Trough width, mm 2x15 or 2x18.5 Trough width, mm 534 Chain speed, m/s 0.9 Conveyor throad height, mm 400 Stage loader Type belt conveyor fitter to the rear side of the roadheader and to the monorail carrier   electromechanical drive Electric drive motor, kW 18.5 Belt width, mm 650 Belt speed, m/s 1.45 Length, mm 11400 Flushing System Flushing points cutting head/material transfer from the scraper conveyor/from the reloader Water pressure in the flushing system, MPa, min 1.5 Water discharge for the cutting head flushing, l/min, max 70 Overall machine dimensions in a transportation position, mm  - length (without stage loader) 10400  - width over crawler 2600  - width over feeder 3670  - height over body 1900  - height (cutting boom) 2020 Voltage, V 1140/660 Rated current frequency, Hz 50 Total rated power of electric motors including, kW 300 Weight, t 45 Ground pressure, MPa, max 0.15 Clearance, mm 270 The plant’s design bureau is capable to work out and complete machines also with other equipment depending on customer demands
