At present, with the start of large-scale projects in China, the crushing and drying of materials provides a broader market for sand dryers. The market demand for sand dryers is sufficient.

Sand dryer continuously strengthens its innovative R&D capabilities, improves the economic development of China's construction industry, makes indelible contributions to China's construction economy in a different era, and sells grain from the Jinhua mechanical dryer manufacturers year after year. The increase in the number of dry machines shows that there is a great momentum of development.

Sand dryer can be used for sea sand, river sand, surface sand, quartz sand and other products, itself has a strong thermal recycling line, at the same time, the initial moisture of the material is higher than 75%. Environmental pollution-free without any combustion and emissions, is a sustainable development of environmentally friendly products. Sand drying equipment will not produce any harmful substances in the drying process, and there will not be smoke or open flame in the drying process. The temperature and humidity can be modulated according to the characteristics of the drying materials, and the degree of intelligence is high. The entire system operates without the flammability that may exist in conventional dryers. The drying process does not require special care. After the material is baked or the drying temperature is reached, the unit will automatically shut down to achieve energy-saving effect.

The sand dryer material is evenly spread on the welded mesh belt by an automatic batcher. The mesh belt generally uses a 12-60 mesh stainless steel mesh and is moved by a transmission device to move in the dryer. Its energy-saving capacity is more than 50% energy saving than electric heating tube infrared microwave energy, 40% energy saving than burning oil, 20%-30% energy saving than burning coal, and the unit will produce cold wind during drying process, and the cold air will be directly discharged into the workshop. Increase room temperature. The dryer consists of several units. Each unit has its hot air circulated independently. Part of the exhaust air is discharged by a special dehumidifying fan. The exhaust gas is controlled by a regulating valve. The heat is sent from bottom to top or from top to bottom. The process of mass transfer takes away material moisture.

N95 Face Masks

The N95 mask is one of 9 types of particulate protective masks certified by NIOSH (National Institute for Occupational Safety and Health). N95 is not a specific product name, as long as it meets the N95 standard, and the product passed the NIOSH review can be called the N95 mask, which can filter particles with aerodynamic diameter and physical diameter of 0.075µm±0.020µm to more than 95%.


N95 mask is one of 9 kinds of particulate protection masks certified by NIOSH. "N" means not resistant to oil. "95" means that when exposed to a specified number of special test particles, the particle concentration in the mask is more than 95% lower than the particle concentration outside the mask. The 95% value is not the average value, but the minimum value. N95 is not a specific product name, as long as it meets the N95 standard, and products that pass the NIOSH review can be called "N95 masks." The protection grade of N95 means that under the test conditions specified by the NIOSH standard, the filtering efficiency of the mask filter material to non-oily particulate matter (such as dust, acid mist, paint mist, microorganisms, etc.) reaches 95%.
