摘要:
A high-speed fine pulverizer wherein a fixed top grindstone is mounted in a pulverizing chamber with a reduced pressure-tolerable mechanism, a rotating bottom grindstone is arranged in opposition thereto and mounted firmly to a rotating disk with a plurality of ejection wings for reduced pressure and disposed around the rotating grindstone, and an intensive reduced-pressure jet stream is caused by the high-speed revolution of rotating bottom grindstone to such air from a central opening of fixed grindstone, thereby forcedly passing the pulverizing raw material fed from said opening through the clearance between both grindstones at high speed while whirling it so as to be finely pulverized, wherein the pulverizing raw material can be pulverized finely at ambient temperature without a rise in temperature, allowing the conversion of foods etc. to powder without thermal transmutation. The invention can also include equipment for producing finely pulverized powder, including a high-speed fine pulverizer and an air classifier.
摘要:
A grindstone-polymer composite for a super colloid mill characterized in that, in the inner void pores of the porous vitrified grindstone for the super colloid mill, thermoplastic and thermosetting polymers are allowed to fill the void pores of the wall surface within a range of 30 to 60% of total volume of void pores in said grindstone so that 70 to 40% of void pores in the grindstone for the super colloid mill remain and the volume fraction Vp thereof lies within a range of 0.09 to 0.21.
摘要:
The printing offset blanket in accordance with the present invention has a surface printing layer made of a mixture of silicone rubber and oil-resisting rubber. It is therefore possible to prepare ink layers having a uniform thickness and clear edges. Further, the present offset blanket can be improved in paper discharging properties and retention of paper powder, enabling the blanket to be suitably applied to high-speed printing, filter or display prints, or the like. The printing rubber roll of the present invention is made of a mixture of silicone rubber and oil-resisting rubber. Accordingly, the present rubber roll is excellent in stability with respect to ultraviolet-curing ink and can therefore be used for a long period of time.
