At present, the mainstream gold selection process is generally first broken by crushing equipment ( jaw crusher , cone crusher ), and then processed by gold ore dressing equipment such as classifier, mixing tank and flotation machine. Through re-election and flotation, the concentrate and tailings are extracted, and then the gold ore dressing agent is used to smelt through chemical methods, and the product finally becomes the finished gold. In this article, we will introduce the complete equipment for gold ore dressing. Jaw Crusher : An efficient and energy-saving crushing equipment, mainly used for the crushing of various ores and bulk materials. It is divided into coarse and fine broken, and is the first equipment for primary crushing of gold mines. In the process of breaking up huge ore into small pieces of minerals, the first crusher is often referred to as the "main" crusher. It is also the longest and most sturdy crusher, and it is also a key link to ensure production efficiency. Flotation machine: Refers to the mechanical equipment to complete the gold mining flotation process. In the flotation machine, the gold slurry obtained by adding the chemical agent is agitated and aerated, so that some of the ore particles are selectively fixed on the bubbles; the surface of the slurry is scraped to form a foam product, and the rest remains in the foam. In the pulp to achieve the purpose of separating minerals. Widely used in rough selection, selection and reverse flotation of non-ferrous metals, ferrous metals and non-metallic minerals such as gold, copper , lead , zinc , nickel and molybdenum . The gold mine flotation machine has the following characteristics: 1, large inspiratory capacity, low power consumption; 2, each tank has three functions of suction, suction and flotation, self-forming flotation circuit, no need for any auxiliary equipment, horizontal configuration, easy to change the process; The slurry circulation is reasonable, which can minimize the advantages of coarse sand sedimentation. High efficiency ball mill : Used for grinding of materials such as gold ore. Gold mines can only achieve sufficient strength after grinding and to the required fineness, so that the products can reach the strength. Grinding is an important procedure in the production of aerated concrete. The grinding process consumes a large amount of electricity, and the high-efficiency ball mill is generally added. The largest motor capacity in a gas concrete plant. The high-efficiency ball mill is widely used in gold ore beneficiation. The mined gold ore is firstly crushed by a jaw crusher. After being crushed to a reasonable fineness, it is evenly sent to the ball mill through the hoist and the ore feeder. The ore is crushed by the ball mill. Grinding. The ore fine material developed by the ball mill enters the next process: classification. The spiral classifier classifies the ore mixture by the principle that the specific gravity of the solid particles is different and the speed is often different in the liquid.
The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
The role of edge banding: PVC Edge Banding For Office,Pvc Edge Banding For Office,Pvc Edge Banding For Office Table,Pvc Edge Banding For Office Furniture Henan Shunbang Chemical Industry CO.,Ltd , https://www.pvcresinchemical.com
First, the edge banding has the function of blocking harmful gases such as formaldehyde
Good edge banding or multi-sided edge banding can reduce the amount of formaldehyde emission per unit time (ie, slow down the emission rate). It is worth noting that edge banding will not reduce the formaldehyde content of the board, but this has the advantage of edge banding. It can reduce the formaldehyde emission per unit time of unenvironmentally-friendly sheets to a level that is acceptable to humans and does not affect health.
Second, the role of beautifying furniture
Good edge banding has the effect of beautifying office furniture, but if it is to be beautiful, the requirements for edge banding will be higher. Not only must the edge banding and the end surface of the board be firmly and smoothly combined, but also that the edge banding must be combined with other The joints of the surfaces should not have defects such as bottoming, chipping, and large gaps, and the transition should be natural, smooth and smooth.
Third, extend the service life of office furniture
The precise edge sealing design of the board can prevent water or other liquids from entering the board, avoiding the expansion, deformation and breeding of bacteria on the desktop, thereby prolonging the service life of the office furniture, and the office furniture after the edge sealing treatment is also more expensive in terms of cleaning easy.
Fourth, avoid sharp edges and corners from hurting people's bodies
The general edge banding will use the dull edge banding design to smooth the corners of the table, thereby reducing the damage to the body by the sharp corners
