	Capacities AN Bin - 11,300 kgs. / 24,900 lbs. Fuel Tank - 1,000 litres / 260 gallons Auger Output - 350 kgs. per minute / 770 lbs. per minute
	Ammonium Nitrate Bin Capacity 11,300 kgs. / 24,900 lbs. Manufactured from 3mm - 304 stainless steel Divided into three compartments by two baffles Valley of bin 90 degrees Three filling points Sliding aluminum cover over all filling points An aluminum walkway fitted to the left hand side of the bin Bin positioned in a 6mm saddle, which will allow for mounting to supplied cab chassis A tent to be provided in the bottom of the bin over the belly auger to help relieve the pressure on the auger
	Process Fuel Tank Capacity 1,000 liters Manufactured from mild steel Positioned at the rear of the AN bin Fitted with level indication tube Top filling point only
	Auger System 3 augers will be installed A belly auger (200 mm) with varied pitch for limited binding along the bottom of the AN bin A vertical auger (200 mm) located to the front of the AN bin A discharge auger (200 mm) located so it disharges over the cabin of the unit A metering tube will be fitted to the outlet of the AN bin All augers will be suitability sized to meet the above discharge rate All auger material will be 304 stainless steel The vertical auger will be fitted with an inspection door at the bottom of the auger A further inspection door will be provided in the transition drop between the vertical and discharge augers Teflon seals will be fitted to both ends of each auger All auger support bearings will be spaced away from the end of the auger tube, to prevent product leaking into them in the event of a seal failure All auger stub shafts will be 1 1/2" diameter, supported by two 1 1/2" flange mounted, self aligning ball bearings and taper sleeves
	Discharge Auger Movement A lifting ram will be fitted to the discharge auger to enable it to be raised and lower as needed A counterbalance valve will be fitted to this ram to prevent the auger from dropping in the event of a hydraulic hose failure Discharge auger will rotate approximately 270 degrees from its resting cradle located on the top of the AN bin A flexible tube will be supplied for connection to the end of the discharge auger so product can be directed out of the auger and into the blast hole Auger movement will be controlled by electric over hydraulic valves with a joystick located in the chassis cab for proportional movement of the discharge auger Electric controls will be provided in the cabin of the unit
	Hydraulic Oil Tank Capacity of approximately 300 liters Manufactured from mild steel Painted internally Level indication gauge will be installed Tank will be positioned at the front of the AN bin A return oil filter will be fitted to the top Heavy duty breather will be fitted Outlets and drain points will be fitted to the bottom of the tank Drain to be fitted with a plug Outlet to be fitted with a ball valve Drain to be fitted with a plug Outlet to be fitted with a ball valve Tank will be supplied full of hydraulic oil (ATF will be utilized unless otherwise directed by customer)
	Hydraulic System All hydraulic valves will be fitted to a single manifold Speed control valves will be provided for all functions Solenoid valve will be provided for the electrical stopping and starting of each auger or pump A manual by-pass valve will also be provided to stop and start the batching system. This valve will be provided external of the cabin A Kawasaki piston pump will be provided All necessary controls will be provided so the auger-loading systems may be used
	Hydraulic Controls The hydraulic system is operated by a Kawasaki pressure compensated hydralic pump mounted with a driveline to a PTO with a minimum of 35 gallons of hydraulic oil per minute at 1800 RPM with a PTO with minimum ratio to the engine speed of 1:27 to a pressure relief valve installed in the valve bank to protect the system in the event of elevated pressure and is set to relieve at 2200 psi. A pressure filter will be installed on the pressure line for additional protection of the hydraulic system. A hydraulic cylinder raises and lowers the discharge auger. The following ingredients will be proportionally controlled by the on board control panel and will be closed loop control so the operator does not have to adjust speed: AN Auger: Controlled to the speed of the delivery as set in the panel Fuel oil: Controlled as a percentage of fuel delivered in the mix We will install Hawe proportional hydraulic valves which will have handles installed. Hawe valves do not require proportional on/off coils, so either coil is applicable to on/off or proportional operation. The handle on the valve allows your operators a means to manually turn on and off or reverse any of the hydraulic motors independently of the other motors in the system or independently of the control panel, from within the hydraulic bank (mounted on the fender of the unit on the driver's side) if required. This system will be quoted with a piston pump and will be sized to discharge ANFO product at 300 kgs per minute. AAMCOR Control Panel A Sauer Danfoss Custom Computer control panel (CAN software) will be installed in the cab of the chassis and will be shipped loose so we can install in the chassis (of your choice or one you supply to AAMCOR). This control panel will set any blend percentage of ANFO, any discharge rate up to 300 kgs per minute. There is an electronic GPI flow meter in the fuel discharge line that sends a signal to the processor for precise delivery of actual fuel that is flowing into the AN at 6%. The display will have a calibration screen to input the AN and fuel (LBS/pulse) which will be used in the blend monitor screen. The run screen will have a section to input the amount of product to be delivered and at what rate it is to be delivered at. The monitor shall display whole and day total on the screen for AN and fuel. This AAMCOR panel will also allow the operator to visually inspect and monitor the ingredients as follows: Manually start and stop the production and delivery of the explosive product Preset the desired weight of product to be delivered to the bore hole, display how much product remains to be delivered, and automatically stop production when the preset amount has been delivered Maintain cumulative totals of the weight of product and the weight of each ingredient that has been delivered (fuel also has its own display on the flow meter A joystick will control the up / down and rotation of the discharge auger from within the cab of the chassis Wireless remote controls can be added to any control system for remote operation of the mixing delivery system
	Electric Controls The Plus1 control panel components will be fitted into a mounting cabinet which will be installed inside the cabin of the cab chassis for single operator control Emergency stop will be fitted to the control panel Controller will indicate ingredient rates and percentages. This will provide a batch amount and a totalizer. These amount will be indicated in kilograms Auto / manual switch will be provided Stop, start, and reset switches will be fitted A proximity switch will provide the necessary inputs for the batch controller Proximity switch will be fitted to the belly auger drive motor A fuel flow meter will be provided so the amount of fuel in the mixture can be known All wiring external of the cabin will be placed in conduit
	General The body will be installed to suit requested cab chassis Guards will be provided over the drive wheels of the unit An aluminum walkway will be fitted along the top of all bins and tanks Top access will be provided at the rear of the unit by an access ladder Mounting brackets will be welded to the body, matching amounts for the chassis will be provided All necessary mounting bolts and springs will be provided The unit will be painted in two pack epoxy paint All necessary sign writing will be installed on the body A full operation and parts manual will be provided
