FIELDS OF APPLICATION

Dual Roll Sizer are utilized for primary as well as secondary crushing associated with soft and medium-hard in addition to sticky and moist materials. They are particularly employed for primary crushing within open pit mining (ROM) in addition to further crushing (2nd + third crushing stage).

FEED MATERIALS

double_roll_crusher

double roll crusher

Lignite, coal, soft to medium-hard stone, different types regarding ore, chalk, gypsum, limestone, marl, clay courts, bauxite, different forms of phosphates, oil mud, overburden and similar garbage.

MODE OF OPERATION

The feed material may be crushed either simply by counter-rotating rolls with the Center-Sizer (Type 2326) run-ning inward inside the flow direction with the material or among a crushing plate/comb as well as the outward rotating rolls with the Side-Sizer (Type 2327).

SECIAL FEATURES

Housing:

  • simple, extremely compact, sturdy design
  • the bearings with the crushing rolls are arranged inside the front parts with the housing
  • the housing is fixed over a steel frame or perhaps concrete foundation

Crushing sheets:

  • consisting with the shaft complemented together with crushing rings/crushing segments as well as the bearings
  • the staggered and also helical arrangement with the crushing elements permits continuous material feed along with batch processing.
  • The material will be evenly distributed on the whole width with the roll and is crushed for the appropriate size.

Drive:

  • consisting regarding mechanical coupling products coupling), gear, basic couplingand motor auto-reverse operation
  • drive unitconsistingof common components

Drive set up:

  • arranged about both sides (diagonal)
  • drive arranged using one side (parallel)

ADVANTAGES

  • compact and flat design causing a low/flat overall height with the crushing plant
  • minimum quantities of fines inside the final product as a result of low circumferential velocity and special enamel configuration
  • low airborne dirt and dust burden
  • easy substitute of crushing sectors and comb plates
  • inclination of part walls is adjustable to boost materialfeed and ingestion of largerfeed lumps
  • in most cases pre-screening just isn’t necessary, as the fines within the final product can smoothly move across the crushing tools
  • high throughput sizes (up to 5000 t/h) with low operating costs
  • low specific wear rate as a result of slow circumferential speeds
  • insensitivity to be able to smeary, ductile, damp and sticky nourish materials

SCOPE REGARDING APPLICATION

  • feed size: uptoapprox, 1500 mm
  • product size; capacity: upto 5000 t/h
  • reduction ratio: 1:4 up to 1:6
  • required power: upto 2×600 kW
