Sand dryer

Product introduction

River sand is a kind of smooth, round, solid, non-toxic, tasteless natural high-quality construction sand, which has less salt content and will not cause corrosive effect on steel bars in reinforced concrete, so it has better use value than sea sand.

Natural river sand contains a certain amount of impurities and a large amount of water. It needs to be washed, dried and screened before it can be fully used. It is mainly processed into various dry powder mortars (including thermal insulation mortar, surface mortar, etc.). The drying process of river sand is very important, and it is directly related to the quality of the finished river sand. Here we recommend the river sand dryer produced by Shuguang Machinery. This equipment is specially developed for the nature of river sand and has a very good drying effect. Next, I will introduce this high-efficiency river sand dryer.

Working principle

The heat source of the river sand dryer comes from the combustion device. The dryer adopts the forward flow heating mode. Therefore, the river sand materials that need to be dried slip into the cylinder body from the feed box and the feed material, which is pushed back by the screw plate. Due to the tilt of the dryer, on the one hand, the river sand flows to the back end under the action of gravity and rotation, on the other hand, the river sand is repeatedly picked up by the plate, carried to the upper end, and then continuously spread down, so that the river sand materials form a uniform curtain in the cylinder, and fully exchange heat with the hot air flow in the cylinder. Due to the repeated spreading of river sand materials, the water contained in the sand is gradually dried, so as to achieve drying.

Performance advantage

1. In terms of structure: the river sand dryer adopts advanced production technology, and the structure is compact and reasonable. Its floor space is only 1/3 of other dryers, which can save the civil construction investment cost of the river sand plant;

2. In terms of material: the cylinder and the discharge part are made of high-quality steel plate materials, which have good wear resistance, high temperature resistance, corrosion resistance, etc., which can extend their service life;

3. Feeding advantages: through special design, it can feed the river sand material uniformly and continuously, avoiding the blockage of the feeding end caused by the river sand too fast, and also preventing the idling phenomenon caused by the slow feeding;

4. Thermal efficiency advantage: The equipment has good heat preservation function and full use of heat energy. Compared with traditional dryers, it can increase its thermal efficiency by more than 50%, greatly saving equipment energy consumption;

5. In terms of effect: the quality of the river sand dried by this equipment is strong, the dry humidity is moderate, and the impurities are less. It has a good use effect and is unanimously recognized by the construction industry;

6. Environmental protection: The sealed drying structure is adopted, and the discharge port is designed with a dustproof device, which can completely avoid dust leakage during the drying or discharge process, and fundamentally solve the problem of dust pollution.
