Quality of pure kaolin has a high whiteness, soft, easily dispersed suspension in the water, good plasticity and high adhesion, excellent electrical insulation properties; has good resistance to acid insoluble, low cation exchange capacity, better fire resistance and other physical and chemical properties. Kaolin has become necessary for mineral raw materials, paper, ceramics, rubber, chemicals, paints, pharmaceuticals and defense in dozens of industries. At present, the global kaolin production of about 40 million tons of refined soil of approximately 23.5 million tons. The paper industry is the largest consumer of refined kaolin sector, accounting for kaolin consumption of 60%.

Kaolin is widely used in the paper industry. The kaolin There are two main areas, a filler used in the papermaking process, and the other is the use of pigments in the surface coating process. For 10-20% of the general cultural paper, packing accounts for paper weight. For coated paper and paperboard (kaolin ore, including lightweight coated paper, coated paper and coated paperboard), in addition to need to fill, but also need to paint, fill in the kaolin proportion of pigments for the paper weight 20-35 %. Kaolin used in paper making, to give the paper and good coverage properties and good performance of the coating gloss, but also to increase the whiteness of the paper, opacity, smoothness and printability, greatly improved the quality of the paper.

Shanghai Kefid Machinery Equipment Co., Ltd. can not only be successful grinding processing of kaolin material, more extensive processing of quartz, feldspar, calcite, silicon carbide, thermal insulation materials, Mohs hardness below 9.3 and humidity below 6% non-Yi burning non-explosive materials.  Shanghai Kefid Machinery on a variety of series, different types of mill manufacturing and R & D experience.

Which of TGM trapezium grinding mill to have an unparalleled advantage, the application number of the latest national mill patented technology, innovative design, reasonable structure, small footprint, low power consumption, long operating life, and wearing parts, low cost, cost-effective higher characteristic.

Its technical performance has reached world-class advanced level, compared to the ball mill, Raymond mill, high pressure hanging roller mill, and other traditional mill has five technical advantages:

1 can improve the grinding efficiency of the grinding roller and grinding ring. The aircraft will be grinding roller and grinding ring are designed ladder, reduce the rate of decline into the grinding roller and grinding ring material, thereby prolonging the time of the RCC material, improve the crushing effect.
2 can play balance supercharging pressure spring, and can play smooth damping effect of the elastic links. The machine uses leverage, symmetrical roller assembly rod connected with the horizontal spring, when the bulk material top to put a roller assembly, the radial force can be passed to the plane of symmetry through spring rod the roller assembly to balance this condition, the device's overall power point and other products compared to about 40%; elastic coupling devices to reduce the vibration and noise, to avoid resonance.
Equipped to improve the accuracy of the powder and products of high density powder separator impeller. The practice shows that the speed unchanged, increasing the density of the leaves can increase the fineness of the finished product, in other words, the product fineness not need to change the case of low speed, high density impeller than the low-density impeller, reducing airflow resistance, same power under the finished production increased more than 50%.
(4) with energy efficient centrifugal induced draft fan. The efficiency of prismatic blade equipped with the traditional machine is only 62%, while the impeller and blade are both stamping, energy-saving efficiency of the induced draft fan for more than 85%.
Convenient impeller adjusting device. The powder leaves the end of the shell gap size also affects the fineness of finished product, patent technology allows adjustment of the gap size is convenient.
6 The unique design of tilted inward duct to ensure that the material smoothly into the wind Beng into the nest inside the containment along the ramp falling into the mill.
