Winter is the most troublesome time for users of totary sand dryers in dry mortar producing plant, because the temperature of the cylinder of sand dryers volatilizes quickly, especially in snowy days, so how to ensure the sand dryer has sufficient temperature in winter? If the sand can not achieve the desired effect, then we have to dry the sand twice or more times, which greatly increases the production cost, this is a result that we all don't want to see.


Regular checking-How to control rotary sand dryer temperature in winter

In winter, the outside temperature too low, in order to ensure the original temperature of the sand dryer equipment, it is necessary to work hard on the temperature of the cylinder of sand dryer equipment. Here are some skills from ANT CONSTRUCTION engineer to control sand dryer temerature in winter to share with our customers.

First, according to the temperature display on the temperature control device, it is one good method to control the amount of fuel added for the  sand dryer. In order to avoid too much or too little fuel causing a large temperature fluctuation, adding fuel multi times by small qty each time will save resources and it is good for controlling of sand dryer temperature. According to the material you are drying, you should flexibly choose the temperature it needs. If the fuel type is single, you can control the temperature by increasing or reducing fuel. If the material need to be drying at a high temperature, a fuel with high calorific value should be selected at this time.

Second, install a temperature control device that can always detect the temperature inside the sand dryer. The operator of the dryer must record the temperature, analyze the temperature changes, and make corresponding adjustments according to the changing situation. It is also possible to achieve the goal of increasing the temperature by adjusting the ventilation of the drying equipment during the drying process and reasonably controlling the air brake of the drying equipment.

In the cold winter, the dryer must keep warm. The temperature drop of the dryer in winter is normal, ifwe can do it well in warmth work, the sand dryer will work well to avoid the phenomenon of being dried multiple times and increase our cost.


How to check oif Drying temperature does not rise


  1. Check whether the intake valve is open;

  2. Check whether the solenoid valve is in good condition;

  3. Check whether the computer version is output;

  4. Check whether the trap is in good condition;

  5. Check whether the fan rotates;

  6. Whether the fluff inside the machine is cleaned;

  7. Whether the external exhaust chimney of the dryer is unblocked;

  8. Whether the protective net on the heater has not been cleaned for long time.


How to check if The fan does not rotate, 

Check whether the contactor is closed;

  1. Check whether the security fuse is burned;

  2. Check whether the thermal protection works normally;

  3. Check whether the motor is burned out;

  4. Check whether the power supply lacks phase.
