What are the properties of nano sand mill

Nano sand mill adopts material pump to send the solid-liquid mixture material which is pre-dispersed and wetted by the mixer into the cylinder, which can realize the continuous processing and continuous discharging of the material and greatly improve the production efficiency. Nano sand mill is suitable for the dispersion of various viscosity products and the grinding of nanoscale materials. According to its processing performance, nano sand mill can be applied to rough processing in addition to mechanical finishing. For example, deburring of certain plate and disk-shaped porous parts, rough surface treatment of certain powder die castings before use to remove surface fretting and dents, as well as non-magnetic parts, stainless steel and some non-ferrous metal parts, etc. As the electromagnetic suction cup of the grinder can not be sucked, and can not be processed in multiple parts, the nano-sander is used to grind the blanks for rough processing of large-size blanks and some rough maintenance work. Nano sand mill performance: 1, Energy ratio: nano sand mill adopts a new type of rod and pin grinding rotor, so that the nano sand mill can concentrate kinetic energy, thus giving the grinding bead energy ratio. It can effectively improve the grinding efficiency and fineness, and at the same time reduce the resistance of the material in the grinding chamber, which is suitable for materials with medium and high viscosity and ultra-fine requirements. 2、Omni-directional cooling: adopting internal threaded guide type cylinder cooling method, plus double cooling of the top cover, the heat dissipation efficiency is 2-3 times of the traditional sand mill, to ensure the effective distribution of heat inside the sand mill. 3, Lengthened bearing seat: integrated machining process annealed to eliminate welding stress, deep machining formed by the boring machine, to solve the nano-sander bearing bit caused by the spindle jump, affecting the stability and service life of the problem.

How to balance the temperature of stainless steel reactor

Stainless steel reactor needs to maintain the temperature balance, because only after the temperature balance, we can make the chemical reaction more smoothly, to maintain the temperature balance, then we can use certain methods to solve the problem, here we specifically say to maintain the temperature balance of the methods are? First, to manipulate the reaction rate of the stainless steel reactor, the opening disk is not too fast, when the equipment is used people usually rush, mechanical rotation to the value, in fact, this method is often counterproductive. In this case, the equipment is very easy to reverse, RTD will cause deformation of the mixing kettle. In addition to this, remove the deformation, which also causes the body temperature to rise rapidly, destroying the mechanical properties. Second, you also need to control the refrigeration temperature of the stainless steel reaction kettle, gradual cycle, if it rises to the rated temperature, it will form an impact on the material reaction. In this type of situation, the actual effect of refrigeration system refrigeration is very important, but pay attention to the cycle gradually, to prevent the formation of too large a temperature difference. Third, in order to balance the temperature, but also need to be its material processing volume should be within a reasonable range, so the more the number of material processing, stainless steel reactor temperature is also higher. This is to remind the equipment operator may temperature, due to too much material, did not reach the ideal temperature in the specified time, but this is normal.

The main working characteristics of high-speed disperser

The main part of the high-speed disperser is the impeller, which is driven by the high-speed rotating dispersing shaft and rotates at high speed. The high-speed rotation of the impeller makes the paint slurry in the mixing tank present a rolling circular flow and produce a big vortex. The pigment particles located on the top surface of the slurry will soon spiral down to the bottom of the vortex. A turbulence zone is formed at the edge of the impeller 2.5-5cm. In this area, the pigment particles are subjected to strong shear and impact effects, so that they are quickly dispersed into the paint slurry. Outside this area, the formation of upper and lower two flow beams, so that the paint slurry is fully circulated and turned, can play a good dispersion effect. The disperser adopts various specifications such as electromagnetic speed control, frequency conversion speed control and three-speed, stable and powerful operation, suitable for all kinds of viscosity; hydraulic and mechanical two lifting forms, lifting and rotating freely, adapting to a variety of positions; ordinary and explosion-proof configuration, safe and reliable, simple operation and maintenance; strong production continuity, the material can be quickly dispersed and dissolved, dispersing effect is good, high productivity, smooth operation, easy to install. There are different power and models for different material viscosity and processing capacity.
