The ACM/C series grinders are the result of our latest innovations (Patent Registration No.20031056858) and are specially designed for grinding heat sensitive materials. The range contains special grinding accessories/devices and features a coarse material re-grind system as well as are-blowing machinism. Specific features of the C series are as follows: 1. Ability to grind brittle materials that are prone to over-grinding, producing a "coarse" (d97>140�m), i.e. blow mesh 100) finished product with consistent granule size and even distribution. Suitable for grinding materials such as polyvinyl alcohol (PVA), with more than 80% of the total amount of retention for the neighbouring three sifting numbers (i.e. sifting meshes 40,60 and 80). 2. Has a re-blowing device, suitable for grinding heat sensitive chemical materials (such as PVA), ensuring that their properties will not deteriorat due to the temperature generated during grinding. This reduces the chance of materials forming spheres caused by high speed spinning and fricton-spherical materials are much harder to grind. 3. The granule size of the product is adjustable by adjusting the gaps between the grinding accessories/devices. The machine is capable of grinding both coarse materials (below mesh 100) and fine materials (above mesh 100). 4. Low cost-priced at less than 30% of similar imported machines. The machine is suitable for grinding coarse or fine heat sensitive materials, capable of producing consistent granule size. It is therefore widely used in chemical, agro-chemical, foodstuffs, starch and Polyvinyl Alcohol production industries. These machines have demonstrated very stable performance and good reliability as evidenceed by a large number of installations in China's leading vinylon plants, silicon gel plants, and starch processing facilities, having completely replaced similar imported machine. The machine's main inner linings, whirlwind separator device, dust remover and pipe system are made of either alloyed carbon steel or stainless steel, depending on the specific industry for which the machines to be used. -
