A synthetic turf system includes a plurality of synthetic turf fibers and a plurality of ceramic pellets interspersed among the synthetic turf fibers. The ceramic pellets have a hardness on the Mohs scale of 6 to 8, a density of 0.5 to 2.15 g / cm3, and a sphericity and roundness rating of 0.7 to 0.99. The ceramic pellets include a mixture of alumina fines and at least one of kaolin or bauxite. The ceramic pellets are chemically inert and free from respirable quartz silica dust. The ceramic pellets may include a ceramic pellet core and a coating. The coating may be configured to control thermal properties of the ceramic pellets. The synthetic turf system may include small ceramic pellets configured to remain near a surface and large ceramic pellets configured to settle towards a bottom of the system.

This utility model relates to a wire drawing equipment and a rod feeding device for preventing silica dust accumulation, aiming to solve the technical problem that silica dust easily accumulates on the rod feeding mechanism and positioning mechanism, thus affecting product quality and equipment life. The rod feeding mechanism is mounted on the frame and is used to convey at least one row of quartz rods forward; the positioning mechanism is mounted on the frame and is used to position each quartz rod so that it passes through the set area of ​​the corresponding flame nozzle of the melting burner; a protective cover is used to cover the rod feeding mechanism and the positioning mechanism in front of the melting burner. The protective cover includes a front plate for feeding and a rear plate for discharging. The front and rear plates are respectively provided with clearance holes for the quartz rods to pass through, and a sealing plate is provided between the front and rear plates.
