Чтобы подключить стационарный грохот к мобильной щековой дробилке, нужно выполнить 3 этапа с соблюдением параметров производителей по выравниванию опор, монтажу лотка, настройке вибраций, используя стандартные комплектующие.
The formation of a bridge in a jaw crusher is identified by an increase in the drive current, increased noise and a drop in output; these signs differ from those of bearing faults, and the machine should not be operated for more than 15 minutes in such circumstances.
False triggers of the cone crusher’s hydraulic protection system (in the absence of metal) are caused by instability in the hydraulic system’s parameters: pressure deviation >0.8 MPa, contaminated filters, valve offset >0.2 mm, changes in oil viscosity, and bearing wear. Check every 240 hours of operation.
To prevent the dust suppression system from freezing in winter, you should check the thermal insulation of the pipes, maintain the coolant temperature at +5…+10 °C, run the circulation system for 15 minutes every 2 hours, check the sensors once every 7 days, and drain the fluid if the system is left idle for more than 3 days.
To protect the rotary crusher from steel reinforcement in construction rubble, two separators are installed in series (a 100×100 mm vibrating screen and a 1,200 mTl magnetic separator) and 40-mm hardened protective rotor liners; throughput is reduced by less than 4%.
The loss of traction experienced by a crawler crusher in a quarry is caused by the undercarriage being unsuitable for the gradient, ground conditions, narrow tracks, weight imbalance and hydraulic leaks; there are solutions available to rectify this.
According to the 2025 tests, 92% misalignments were found in the mobile unit’s discharge conveyor—due to misaligned rollers, uneven belt tension and deformation of the bracket. The threshold parameters for faults, as well as the rules for inspection and rectification, are specified.
Three factors cause the hammers in a rotary crusher to crack when crushing reinforced concrete: inconsistencies in the raw material, incorrect clearance and unsuitable hammer material; there are recommendations on how to address these issues.
Following the replacement of the rotor crusher hammers, vibration occurred in 92% cases due to an imbalance: discrepancies in mass, mounting and hammer geometry compared with the manufacturers’ specifications; the permissible parameters and operating recommendations are set out.
The main causes of overload in a cone crusher when there is a steady feed of pebbles are: a mismatch in the particle size distribution of the feed material, excessive wear of the lining, and incorrect adjustment of the gap between the cones.
