ADVANTAGES
 |
CRUSHING EFFICIENCY Effective capture of material particles due to different speeds of rollers. FLUOROPLASTIC OVERLAYS The side walls of the crushing chamber are protected by fluoroplastic overlays. EASY MAINTENANCE The hopper is attached with hinged bolts. The receiving container is fixed by eccentric clamps. GAP AJUSTMENT The adjusting mechanism allows setting the required gap between the rollers and ensure its uniformity. OPERATIONAL SAFETY The end switch excludes start-up without loading hopper. All rotating parts and assemblies are covered by casings. |
|
COMPATIBLE WITH VIBRATORY FEEDERS Completing with VF 1 or VF 2 Vibratory feeders provides:
|
 |
 |
CONTROL PANEL The control panel is designed to start and stop the crusher and provides:
|
|
SPRING BLOCK A block of springs protects the crusher from breakdowns due to the indestructible object, and adjusting the preload force reduces the over- or under-grinding of the crushed material. |
 |
 |
QUALITY SPARE PARTS Rollers are made of tool steel AISI 1066. Complete with a special wrench for replacing the rollers. |
DESCRIPTION OF THE DEVICE
|
The principle of operation of the roll crusher is based on the abrasion (simultaneous compression and shear deformation) of the material between the rollers rotating towards each other. The grain size of the crushing product is determined by the gap between the rollers, the compressive force of the springs and the physical properties of the material. The structure of DRC 200x125 Double-roller crusher includes: loading hopper, frame, rollers, adjusting mechanism, spring block, receiving container and electric motors. The roller housings are fixed on the frame. One roller is installed through the spring block, and the second through the adjusting mechanism. The torque from the electric motors is transmitted to the rollers through belt drives with different gear ratios. OPERATING PRINCIPLE The initial material is fed into the loading hopper funnel, from where it enters the rollers rotating towards each other. Between the rolls, the particle receives a single effect and passes into the unloading zone. Once an indestructible object enters the rollers, it squeezes the roll on the springs and passes into the receiving container, without damaging the crusher. PRODUCTION OPTIONS
