Description: Spray Dryer drying is the technology most widely used in the liquid technology shaping and in the drying industry. The drying technology is most suitable for producing solid powder or particle products from liquid materials, such as: solution, emulsion, suspension and pumpable paste states ,For this reason, when the particle size and distribution of the Âfinal products, residual water contents, mass density and the particle shape must meet the precise standard, spray dryer drying is one of the most desired technologies. Work Principle: High Speed Centrifugal Spray Dryer Series of LPG is gas-liquid co-current flow drying equipment, using high-speed centrifugal atomizer, the liquid will be atomized into fine droplets, then mix with the hot air from the distributor in the dryer, heat and mass transfer exchanges rapidly during the mixing process. In a very short period of time the liquid become dry powdered products. Production control and product quality control is convenient and reliable. It is widely used in the drying production of different types of liquids materials.

 Hot Dip Galvanized Square Flat /Plain Washers
    A washer is a thin plate (typically disk-shaped) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a screw or nut. Other uses are as a spacer, spring (belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). Washers usually have an outer diameter (OD) about twice the width of their inner diameter (ID).
Washers are usually metal or plastic. High quality bolted joints require hardened steel washers to prevent the loss of pre-load due to Brinelling after the torque is applied.
Rubber or fiber gaskets used in taps (or faucets, or valves) to stop the flow of water are sometimes referred to colloquially as washers; but, while they may look similar, washers and gaskets are usually designed for different functions and made differently.
Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces.
The origin of the word is unknown; the first recorded use of the word was in 1346, however the first time its definition was recorded was in 1611.
