Canadian Sand Drying Line

Introduction of successful cases

This production line is a sand drying production line, mainly using a three-cylinder dryer for drying. The customer's demand is about 300 tons per day, so we designed such a production line for the customer.

The sand is sent to the hopper by the belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. The inclination of the feeding pipeline should be greater than the natural inclination of the material, so that the material can flow into the sand dryer (yellow sand dryer) smoothly. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the lower end, and is in countercurrent contact with the material, and some heat carrier and material flow into the cylinder together. With the rotation of the cylinder, the material runs to the bottom end by gravity. During the forward movement of the wet material in the cylinder, the heat is directly or indirectly supplied by the heat carrier, so that the wet material is dried and sent out from the discharge end through a belt conveyor or a screw conveyor. There is a lifting plate on the inner wall of the sand dryer (yellow sand dryer) cylinder. Its function is to pick up and sprinkle the material, so that the contact surface between the material and the air flow increases, so as to improve the drying rate and promote the material. go ahead. Heating medium is generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to capture the materials in the gas. If it is necessary to further reduce the dust content of the exhaust gas, it should be discharged after passing through a bag filter or a wet filter.

Customer Reviews:

The sand drying line designed by Shunzhi mechanical engineers is not only easy to operate, but also has a very high output, and does not require secondary rework. Very much in line with our requirements.
