INTERMEDIATE AND FINE CONE CRUSHERS

OMZ manufactures cone crushers with 1750, 2200 and 3000 mm crushing head diameters. These crushers are available with two types of crushing chambers: KCД for intermediate crushing and KMД for fine crushing. These types of crushing chambers are also available with modifications for coarse crushing (Гp,Гp2) and for fine crushing (T). Additional options include: remote control (Д), feed distributor (П) and vibro isolated base (B). Special designed crushers capable of taking unusually large feed pieces and producing finer or cubed finished product are available on request. The designation of a crusher includes abbreviations denoting its type, crushing head base diameter, modification of crushing chamber and additional modification (if any). Example: a crusher for fine crushing with crushing head base diameter of 2200 mm, crushing chamber modification T, remote control and feed distributor is designated as KMД-2200T-ДП.

◊ Capacities given for crushing dry materials with a compression strength of 100-150 MPa and appropriate prepared feed (limited fines content, clay particles etc).

◊ To ensure an effective operation of the crushers under specific conditions consult the OMZ specialists.

◊ Crusher weights given without electrical, lubrication and hydraulic equipment.

aclinal bracket, provide easiness of erection, centering adjustment and execution of repair works. The forced air-cooling of the propel motors provides unlimited practically drive operating regime at travel along prepared route at the velocity up to 1.1 km/h.

Two-axis hand-worked command-apparatuses, the devices for vibration insulation of operator seat and air-conditioning system create the comfortable conditions for excavator driving.

Electric drive of the shovel main mechanisms is made as the motor-generator system, controlled by thyristor energizers.

Electric driver control system provides optimal mechanical characteristics of drive at high efficiency. Electric drive system is easy to maintain, reliable and provides low operation expenses.

• Reliable gripping of large feed pieces.
• Breaking all pieces with such deformations that will not lead to material compaction and crusher overloads.
• Compression of each piece in the calibrating zone thus maintaining the required product size.

• Free flow of material between compressions thus contributing to high outputs.
• The software developed by the OMZ research center enables us to combine the most suitable crushing chamber shape and head angle, eccentricity and crushing head gyration frequency to minimize the power and liners consumption at the specified product size and capacity.

◊ Ensures a stable crushed product quality, eliminates time and labor consuming manual adjustments.

◊ To adjust the discharge opening the bowl is rotated in the adjustment ring thread using the bowl clamping and rotating devices.

◊ The bowl is clamped for crushing due to axially tightening with a set of precompressed coil springs arranged on the threaded ring flange. To release the clamping force before adjustment hydraulic cylinders are actuated and compress additionally the springs.

◊ The bowl rotating device consists of a hydraulic cylinder with a ram attached on a vertical post.

◊ The device may be operated automatically, when all movements of one adjustment cycle, corresponding to cap rotation angle equivalent to one tooth pitch, are performed sequentially. Otherwise, each movement may be controlled manually.
