    Grinding Principle Horizontal grinder is a kind of ultra-fine particle disperser with horizontal continuous production. Its operation method is to use high-viscosity pumps such as diaphragm pump and gear pump to input pre-dispersed wetted solid-liquid mixture into the grinding tank of the main engine. The grinding tank is filled with appropriate grinding medium, and the grinding medium is given enough kinetic energy by rotating the dispersed blade at high speed. The impact of solid particles in bulk materials produces shear force, which produces more intense collision, friction and shear effects, so as to accelerate the friction of fine particles and disperse the aggregation. It is then separated by a special separator. Separate the dispersed material from the medium and discharge it from the outlet. It is suitable for fine grinding with medium and high viscosity particle size. Such as paint, fuel, pigments, cosmetics, pesticides, electronics, paper and other raw materials dispersion. The main features of horizontal grinder are: advanced design, continuous production of sealed type, uniform grinding and dispersing fineness, good quality and high production efficiency. The dry crust and solvent evaporation of the material are effectively prevented when the material is produced in a sealed state. Double end mechanical seal, double protection, zero leakage. The new dynamic separation structure makes the discharging more smoothly, and the easy bamboo shoot parts are less equipped with outer barrel for moving, disassembling and repairing. The feeding pump adopts gear pump or pneumatic diaphragm pump. The feeding size can be adjusted conveniently and the working performance is reliable. In addition, the horizontal grinder does not need a special installation foundation, it can change the installation location at any time according to the need.

  • Stainless Steel Mixing Tank

    Horizontal sand grinder and vertical sand grinder are different. Horizontal sand grinder has larger sand loading capacity, higher grinding efficiency and relatively convenient removal and washing. At present, the proportion of closed horizontal sand grinder used in paint industry is gradually increasing. Basket grinder is a new type of grinder developed in recent years. It places the abrasive paint in the mixing barrel, grinds and disperses the basket with abrasive medium and agitation into the paint. The equipment is mainly suitable for small batch, multi-product operation, pre-mixing of paint, grinding and dispersing and coating in the same mixing tank. When using the sand mill to produce Yao preparations, some problems have to be avoided. For example, during the grinding process, the viscosity increases and the foam is excessive. After grinding, the viscosity of the system is large and the heat is stored and pasted. Before formulating effective preventive measures, we should first find the root cause of the problem. If the viscosity increases during grinding, it may be because the dispersant is not easy to deform, adsorb fastly and fall off from the surface of particles, which makes the original Yao have low melting point and high boiling point substances. In this case, wetting and dispersing additives can be used to improve the adsorption fastness, the thickness of the adsorption layer, the lubrication between particles and the content of yao. Horizontal grinder with good sealing, heat dissipation and high production capacity, has been favored by more and more users in the industry. 1. Primary startup (commissioning): After the equipment is installed, it should be debugged. The specific steps are as follows: 1) Adding solvent or lubricant which is soluble with material to mechanical seal chamber of horizontal grinder. 2) Check whether the circuit of the equipment is consistent with the electrical wiring diagram. 3) Open the water supply valve and observe whether the water consumption meets the requirements. 4) Open the air supply valve. 5) Add grinding media: Open one or two sand-filling mouth caps on the top of the front end of the grinding cylinder block and add the screened grinding media. The filling quantity, particle size and material quality can be determined by reference to the recommendation or the user's requirements for product quality. 6) Adjust the control range of the instrument. 7) Start the main engine and feed pump, clean the cylinder and pipeline with water or solvent, and then carry out the belt operation. Feed rate of feed pump should be determined according to product quality requirements and the number of grinding cycles set.
