Let us now delve into the key aspects of each component.
Screen
Propel Vibrating screen 1561 handles the materials in effective screening area of 8.5m2 in each deck with maximum size up to 150mm. It creates circular motion with two-bearing oil lubricated exciter assembly.
Its bottom deck with end tensioning deck frame design replaces the wire mesh.
Chassis
Heavy duty I-section welded construction provides maximum strength and accessibility.
Vibrating grid and Tipping grid
Vibrating Grid
Tipping Grid
The vibrating grid and tipping grid is responsible for transferring materials of size less than 100 mm to the feed conveyor. Materials greater than 100 mm are not allowed into the screen.
While the tipping grid is a stationary structure, the vibrating grid produces vibrations so that the materials are screened effectively without jamming.
Feed conveyor
The feed conveyor conveys materials that are passed through vibrating grid/tipping grid to the main conveyor.
Main Conveyor
The main conveyor is responsible for conveying materials from feed conveyor to screen 1561.
Chutes and Side conveyors
Chutes are responsible for transferring materials from screen discharge end to their respective conveyors. There are three chutes - Oversize chute, left-hand side (L.H.S) & right-hand side (R.H.S) chutes.
The side conveyors convey the materials from screen to the second and third deck as an end product.
Oversize conveyor
The oversize conveyor conveys the materials from screen first deck to cone crusher/ VSI equipment for recycling purpose.
Tail conveyor
The tail conveyor conveys fine materials as the end product.
Motorized Pulley
All conveyors are attached with motorized pulley. Up to 95% of the output power produced by the motor is typically transmitted to the drum shell. It consumes less space and is completely protected from water, dust, chemicals, grease, oil, etc.
Engine Package
The engine package consists of the engine and alternator coupled to power the entire equipment.
This safeguards the unit from dust, noise and rain.
Diesel Tank
The diesel tank is used to store diesel for engine consumption.
It is equipped with level sensing and a filler breather.
Hydraulic Control Unit
The hydraulic control unit generates and adjusts the hydraulic pressure and switches its passage. The control unit provides several pressure levels. The line pressure control valve is governed by a solenoid and it controls the line pressure.
Hydraulic Power pack
The purpose of the hydraulic reservoir is to hold a volume of fluid, transfer heat from the system, allow solid contaminants to settle down and also, facilitate the release of air and moisture from the fluid. The capacity of the hydraulic tank is 400 litres.
Crawler
The undercarriage is the part of a moving vehicle that is underneath the main body of the vehicle. Crawlers are heavy-duty machines specifically developed for the transportation and relocation of heavy mining equipment or processing plant equipment.
Radio Remote Controller
The radio remote controller is used as application for track crawler movement. In radio control system, when a command is transmitted from the operator to the receiver (located in the control panel), radio signal transmit to around 50m distance from the machine.
Change Over Panel
The change over panel gives the flexibility to power the plant either by external electric connection or by on-board diesel generator power pack unit. This dual power mode is an optional feature.
Control Panel
The electrical control panel has been designed with a double door to ensure it is dust-proof and water-proof.
It comes with IP55 certification and is mounted on to the machine, which is controlled by the electrical operation via the operating panel. The manual mode and auto mode functions are available in the panel.
While the manual operation becomes possible through illuminated push buttons, auto mode operation is controlled by HMI display.
Engine Controller (DSE4520 SERIES)
The engine controller device is used to start or stop the engine. The electrical parameters are shown in the display, which have been set as per applications.
