Talc processing good assistant - Superfine Mill

Talc principle jet milling process is as follows: & nbsp; slippery stones - crushing - drying - in pieces - fine grinding (Raymond) - superfine (jet mill) - Tornado aggregate - packaging production process is roughly slip First of broken stones from the feeder into the hammer were; the crushed material by bucket elevator and feeder into the vertical drying machine; material after drying and then by hammer crusher into the mine Mongolian fine grinding fine grinding mill talc into the air stream after ultrafine raymond mill. Final product fineness can reach 500-5000 mesh (d97 = 30-5um). Airflow mill used in the industry include disc jet mill, air jet mill fluidized bed, circulating tube type jet mill. Talc superfine high-speed mechanical impact process is as follows: slippery rocks - broken (hammer crusher) - high-speed mechanical impact mill ultrafine - turbo fine grading machine - Tornado aggregate - packaging is generally talc Block after crushing to 8mm directly into the mechanical impact of ultra-fine mill, pulverized product through the turbo Fine Classifier set was collected by cyclone feeder. After the fine grain size classification of products can be returned mill, also available separately as a product. Centrifugal talc autogenous grinding mill and a spin speed of ultra-fine grinding process is substantially similar to mechanical impact of ultra-fine grinding process. 3, the surface-modified talc powder is widely used as polypropylene, nylon and other polymer-based reinforcing filler composite material. Its surface modification can effectively improve the affinity and talc talc filler and polymer binder polymer in the dispersed state, thereby improving the physical and mechanical properties of the composite. Surface modification using surface modifying agent talc mainly various surfactants, paraffin wax, zirconium titanate and aluminate coupling agents, silane coupling agents, phosphate and the like. Modified mainly dry modification process. Modified machines are mainly continuous and fluidized modified, continuous vortex powder surface modification machine (SLG type), high-speed heating mixing and kneading machines. 4, firing wide abundance of Jiangxi region has rich reserves of black talc resource. The reason is that some talc mine disaster contain more organic carbon. In order to develop the use of these resources and talc, calcination process is necessary. Calcination temperature is generally 600--1200 ℃, in this temperature range, the higher the temperature, the higher the whiteness of calcined talc, calcined whiteness of up to 90%. Currently calcining equipment they use the shuttle's kiln, tunnel kiln and kiln.
