Mining Radiators

Corrosion Resistant Mining Radiators

A mining radiator designed for the corrosive environment in India ensures engine efficiency because it helps to maintain it at a safe temperature. It is designed to assist with the transfer of heat from hot coolants that pass within it to an external airflow assisted by a fan.

Materials used for mining radiators

Copper and brass are the main materials used in the construction of mining radiators as they are preferred for their longevity, robustness over long periods and reliability, particularly for heavy industry, transport and mining. 
How a mining radiator works

Mining radiators have a specific role to play, which is the circulation of a cooling material, like oil, water or air. It does not matter what materials are used, or the type of coolant, as the main principal behind the radiator is essentially the same. Coolant is pumped around the radiator and engine using a number of narrow parallel pipes. The fins in the radiator help to transfer the heat out of the tubes and into the surrounding air which is forced over them.

The more tubes there are, the more efficient the cooling, and in the end the better the fuel economy. The only downside of this relationship is that the more likely the radiator needs to be repaired because of the more complex structure. If your mining equipment is hauling loads near to capacity it is far better to fit a heavier duty MPR mining radiator. This means you don’t need to ever worry about engine overheating because of a poorly performing radiator. Any overheating all too often damages an engine, reducing its life and this could be simply a result of installing the wrong radiator.
Design of a mining radiator matters

The best radiator design is the type where the widest part, whether it’s the width or the height, is situated in the direction of the tubes, as this maximises its cooling capacity. When you replace your mining equipment radiator with a M.P. Radiator, you may be given the chance to reconfigure your radiator to improve its cooling performance. 
Recommended mining radiator maintenance

Radiator tubes are very small and in the mining environment in particular where there are numerous contaminants and clouds of dirt and dust it is of great importance to ensure they are kept free of internal pollutants. The coolants attract rust and minerals which originate from the engine block which as time incur blockages inside the radiator tubes. This means it is essential to use filtered, clean distilled water or specially prepared coolant for use in the cooling system. Regular pressure testing and core flushing are parts of the essential maintenance program that ensures long life performance of your M.P.R mining radiator.

then overheating could result in a very expensive rebuild. The third reason why sludge and dirt in the radiator is not desirable is because it can become chemically corrosive, and it then starts to attack the metal walls. Cleaning and flushing the radiator means that this corrosive effect is minimised.
Replacing your mining radiator

If your mining radiator has cooling tubes that have become damaged the only real repair option is to either re core the radiator or replace it with a robust M.P.R mining radiator.  It may not be actually leaking but in no time at all and when you want your mining machinery to be working at full capacity it will be. Once the tube walls have become too thin, a higher pressure might split or fracture them. 
It would be disastrous if you are out on site at a distant location and despite knowing about the shortcomings of your old radiator you hadn’t replaced it.  If only you had stopped for a minute and thought more clearly about it, then you would have replaced your old, worn out radiator with a high performance, long lasting radiator designed to withstand the harshness of the mining environment.

Types of Mining Radiators and Metals Suitable for Harsh Conditions
Down flow radiators

This type of radiator is still quite popular with manufacturers of heavy mining equipment. In a vertical flow-designed mining radiator, the expansion or inlet tank can be found at the top of the core. It is linked by using a hose which is designed to be flexible to the coolant exit housing on the motor. Coolant works its way through the inlet tank and flows along the core into the outlet tank at the bottom of the tank. 
This is also linked by a hose to the inlet on the water pump. This permits coolant to circulate through the radiator at the temperature controlled by the thermostat. The outlet tank found on cars that are equipped with automatic transmission may contain transmission oil cooler units or heat exchangers, which use transmission fluid to ensure cooling.
Cross flow radiators

Modern cars usually use this type of radiator. Cross flow radiators are like down flow radiators, but are oriented on their side. The coolant moves horizontally and not vertically while the header tank can be found on both sides. The header tank, which has a cap on the radiator, is the outflow tank. This is equivalent to the lower tank on the down flow radiator. This cross flow radiator has two obvious benefits, as it allows a more streamlined style, which ultimately reduces the pressure on the radiator cap. This facility helps to prevent cap failure if the radiator over-heats as a result of a blockage.
Tube design radiators

The tubes often possess dimpled walls which increase the fluid’s turbulence as it flows along the tubes. If, for example, the fluid was to flow smoothly in the tubes, the walls of the tube are the only parts that would be directly cooled.  The degree of heat that is transferred to these tubes from the movement of the fluid passing along them is dependent on the differences in temperature that occurs between the tube and the fluid that touches it. 
Any fluid that touches the tube will cool quickly, so not so much heat will end up being transferred. Because of the turbulence that takes place in the tube, so that all the fluid will mix up together, it prevents the temperature rising of the fluid that touches tubes allowing more heat to be extracted, so the volume of fluid in the tube will be used most efficiently.
Fin designed radiators

How much space there is between the fins will affect the radiator’s efficiency. Fins can be closely spaced with 13 fins for every 2 cm, or further apart at about 4-5 fins for every 2 cm. Radiator fins are light in weight and are typically made from brass, copper or aluminium. 
The outer surfaces must be kept clean of all leaves, insects and oil because any fin or tube blockages remove the cooling functions of the radiator.
The best metal for mining equipment radiators is copper

If you are choosing a radiator for your mining plant equipment, a radiator made from copper is the best metal. It has the best thermal conductivity, it resists corrosion and it’s strong, which is just right for a vehicle operating in an often dusty, wet and rugged environment. Copper can be made into radiators easily as not much energy is used to prepare it for a radiator; it’s reasonably light and its price is very competitive with rival metals such as aluminium. A copper radiator will still look in original condition when the rest of the mining truck has all but disintegrated through wear and tear.
