Mobile crushers are track-mounted rock crushing machines that are easily moved around and between production sites. This characteristic makes fire detection, alarming and suppression on such equipment a challenge.
They are widely used in aggregate production, recycling applications and mining operations. Mobile crushers can replace stationary crushing systems, which reduces the need for transportation and therefore reduces operating costs.
Among their fire risk areas are: the electric motors of the crushers, the conveyor belts and the area of electrical power panels.
Now, you'll find out what types of systems Elfire's fire engineering experts have designed for each of these risks.

The Condensed Aerosol fire extinguishing technology was developed by the Space Technology Institute of the Russian Federation - one of the most respected research centres in the world, for the protection of its satellites and spacecraft and today is available through FirePro , an innovative automatic fire suppression system, patented by Celanova Ltd / FirePro Systems Ltd - Cyprus, CE.
The FirePro aerosol generators have inside a solid compound "SBK" (solid bound compound), rich in potassium salts (K), which when activated triggers a chemical reaction (exothermic), quickly turning into a powerful aerosol Tri-Class ABC, which extinguishes fires in seconds classes A, B and C.
Installation and maintenance is extremely simple and cost effective, due to the lack of pressure inside the FirePro and the absence of piping for aerosol distribution. The compact size of the FirePro makes it the ideal protection for critical areas with limited space, where high extinguishing efficiency and economy of installation are vital.
Main Advantages
The Fixed Fire Fighting Kit for Off-Highway Vehicles is manufactured by ANSUL, a company based in the USA, one of the leading companies in the segment of fire protection equipment.
The Fire Alarm and Detection Kit is basically composed of a Linear Temperature Sensor Cable to be installed in the main risk areas of the vehicle, an Electric Manual Activator, and specific modules, which are interconnected to a Control Panel to be located inside the operator's cabin.
In the event of a fire outbreak, the temperature in the emergency area will rise and reach the operating point of the linear temperature sensor cable. With the operation of the temperature sensor cable, the Control Panel receives the information of a fire outbreak, generating an audio visual alarm on its front panel. It will automatically send an electrical command signal to trigger the ABC powder discharge in the critical areas of the machine, thus protecting the equipment and people involved.
The Automatic Fire Fighting Kit aims to suppress fire at an early stage before the fire becomes fully established and spreads into highly flammable areas. As a result, damage is limited and vehicle downtime will be minimal.
The linear temperature detector also called sensor cable, protectowire or LHS is a twisted pair of different spring conductors insulated with the heat sensitive material, this material is designed to soften and allow the conductors to strike each other when exposed to a specific alarm temperature, the different conductors When shorted form a temperature measurement, called a thermocouple, the CTI series control module continuously monitors the continuity of the detectors in the event of an open circuit; the module reports an open fault condition when a short circuit occurs;
The CTI series control module detects the short and measures its temperature, at mechanical damage results in a temperature below that required for an alarm, these shorts are reported as a fault condition, a heat short will result in a temperature at or above that required for an alarm; these are reported as a fire alarm condition.
