Sand Feeding

Sand feeding systems can be supplied in both fixed and mobile types.

Mobile systems can be manually moved, towed by a tug unit or mounted onto a carrier vehicle.  Mobile units are ideal for occasional filling duties or where the number of vehicles and sand boxes are limited.  The advantages of mobile sand filling are that the filling location can be flexible and not dependent on fixed pump locations.  The dsadvantages are that the mobile system takes time to move to the filling location and also has to be refilled at intervals.  Additionally, all emptying locations must be accessible for the mobile unit, meaning hard standing routes are needed in the working areas.

Fixed sand feeding systems comprise a central silo and distribution pump and a network of pies to individual sand pumps located on service aprons.  Often, this service requirement can be integrated onto combined aprons with CET emptying and water filling functions.  The fixed sand pumps each store a quantity of sand locally, so that all pumps can be used at the same time at full flow rate, regardless of the number of pumps in operation at any one time.  Each pump also has its own integrated dust extraction system, again working at full efficiency regardless of how many pumps are in use at the same time.

The sand feeding nozzle can be of a standard type, or can be designed to suit a particular sand box.  In operation, the nozzle is paced in the sand box and latched in position, then the valve at the end of the nozzle is manually opened. The sand flow starts and stops automatically when the level of the sand in the box reaches the end of the nozzle.  This means the operator can place the nozzles into the sand boxes in turn, and then remove them in turn once each box has been filled.  The valve on the end of the nozzle is closed before removing the nozzle from the sand box, so sand spillage is avoided at all stages in the operation.

The sand feeding system also includes stainless steel sand feeding pipe work for long life and a parented low speed sand conveying system.  This system uses true low speed sand conveying, minimising damage to the sand during the conveying process and also minimising pipe wear.
