Need help?Do you have a question about the KOMPLET K-JC 503 and is the answer not in the manual?
The K-JC 503 is a mobile jaw crusher designed for the recycling of materials from demolition and renovation work in the building industry, as well as marble and concrete waste. It is built to crush various types of material, reducing them in size to facilitate the recycling process. The machine can be used directly on site or to process previously stored waste materials.
The K-JC 503 operates on the principle of compression shredding. Material is loaded into a large hopper, which features inclined sides to ensure constant material flow and prevent build-up. The loading conveyor, driven by a hydraulic motor, transports the material to the jaw crusher. The crusher consists of two jaws—one fixed and one mobile—also driven by a hydraulic motor. The elliptical movement of the mobile jaw crushes the material until it is smaller than the crushing gap. The crushed material is then automatically discharged from the machine via an extracting (discharge) conveyor, which is also hydraulically driven and equipped with red rubber belts for protection.
The machine is designed for automated operation once started, eliminating the need for a permanent operator for grinding and material extraction. The engine is started via an ignition key on the control panel. The loading hopper can be fed by a compact loader or other loading devices.
An optional dust suppression system is integrated, featuring a 160-liter water tank, an external level indicator, a hydraulic pump calibrated to 120 bar (water side), and an electric level switch that stops the pump when water levels are low. Eight nozzles spray water onto the material to suppress dust. This system can be activated from the radio remote control when the machine is running and the loading conveyor is in motion. During winter, water additives must be used to prevent freezing.
For enhanced sorting, an optional screen can be installed above the hopper. The machine can also be equipped with a magnetic sorter (magnetic roller and hopper) positioned behind the drive unit, above the discharge conveyor. This sorter, driven by a hydraulic motor, uses a permanent magnet and a rotating belt to separate iron from crushed material, transporting the iron pieces next to the machine. The magnetic sorter's position can be hydraulically adjusted, and it is opened/closed via a control lever on the machine.
The K-JC 503 emphasizes high safety, total mobility, fast installation, low operating costs, and high added value. It is designed for use on flat, solid ground with sufficient grip and bearing capacity. The machine is controlled via a radio remote control, which manages crawler tracks, loading conveyor, crusher, extractor conveyor, and the dust suppression system. An EMERGENCY STOP button on the remote control stops all machine functions except the diesel engine. A wired remote control is also available for emergency situations (e.g., low battery or remote control malfunction), stopping all machine functions except the diesel engine.
The control panel on the right-hand side of the machine includes an EMERGENCY STOP button, engine ignition key, acceleration lever, and tachometer with dashboard warning lights. Manual levers on the right-hand side of the chassis allow for emergency forward/backward movement of the tracks.
Alarm devices include a light and sound column indicating operating status, errors, and low diesel levels. During travel, a flashing yellow and red light with an intermittent sound signal indicates movement. A flashing yellow light signals normal engine operation when stationary or during crushing. Emergency situations activate both flashing yellow and red lights and a steady audible signal.
Regular checks and maintenance are crucial for optimal performance and extended machine life. The manual outlines maintenance intervals based on operating hours (e.g., every 8 hours, 50 hours, 160 hours, 500 hours, 1000 hours, 2000 hours, 6000 hours).
Key maintenance tasks include:
Disassembly for container transport involves removing parts of the hopper and lowering the light/sound column. Decommissioning and disposal require adherence to basic rules, including proper disposal of plastic, rubber, non-metallic parts, and greasy oils, and dismantling metal parts for appropriate demolition companies.
