Gold ore dressing equipment process flow

Gold ore dressing equipment process flow

The amount of gold in ore is so low that in order to extract gold, the ore needs to be crushed and ground and preenriched or separated from the ore by means of beneficiation. Gold is a mineral used in more re-election and flotation, gravity separation in placer gold production occupies an important position, the flotation method is widely used rock gold mining beneficiation methods, about 80% of our country rock gold mine with gold using this method, processing technology and equipment have been greatly improved.

YA type circular vibrating screen introduction

YA type circular vibrating screen introduction

Type YA round vibrating screen is the new equipment introduced by our country that American RS Corporation has the world level technology in the early 1980s, and begins production in the mid-1980s. The technical performance and quality of product has reached the level of similar foreign products. YA circular vibrating screen adopts international advanced ring groove rivet, plate type screen box frame structure, eccentric shaft plus eccentric block vibrator, high performance gear transmission system, low stress damping spring and super heavy large clearance bearing and thin oil lubrication and other advanced technology and technology, It has the advantages of high strength screen frame structure, reasonable mechanical structure, low running temperature rise of large clearance bearing, small running noise, long service life, safe and reliable production and easy maintenance. It is suitable for material classification in mineral processing, coal preparation, building materials, electric power and chemical industry departments. It can also be used for dehydration, desilting, desilting, good quality and high efficiency. In recent years, the screen has been widely promoted and applied in China, and has been well received by users.

The method of determining the spin direction of ball mill

The method of determining the spin direction of ball mill

When the mill adopts the transmission form of asynchronous motor and reducer, there are four kinds of arrangement, including internal right-handed, external right-handed, internal left-handed and external left-handed. When the synchronous motor drives the pinion shaft directly, there are only two kinds of arrangement: left and right. The rotation direction of the mill is determined from the discharge end to the feed direction. The clockwise rotation of the mill is right-handed, and the counter-clockwise rotation is left-handed. Rod mill and tube mill of intermediate ore discharge are not included in this list. When the user orders, should indicate the rotation requirements, otherwise all according to right-handed or external right-handed manufacturing. The identification method of spin direction of ball mill and steel ball mill is shown in Figure 1.
