The spiral separator is the best gravity concentrating equipment, especially for concentrating sand ore in seashore and riverside. It is made of the fiberglass, lined with wear-resistant polyurethane and covered with corundum cover. It has advantages such as lightweight, moisture proof, anti-rust and corrosion, noiseless, very suitable for the different feeding particle sizes and grades.

Capacity: 0.15-8t/h Feeding size: 0.3-0.02mm Advantages: 1. Simple structure, easy to operate and maintain 2. Low energy consumption 3. Relate wide range of particle size 4. Small volume, space saving 5. High productivity and efficiency

Main parts: ore distributor, feed chute, spiral chute section, cutting trough, collecting hopper, support, etc. Spiral separator types: single spiral separator, lab spiral separator, rotary spiral separator, multi-deck spiral separator.

Application: The spiral separators are designed for classifying the granularity 0.3-0.02 millimeters fine grain like iron, hematite, ilmenite, chromite, brasses, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other Non-ferrous metal, rare metal, and non-metallic minerals with different specific gravity in the mineral processing plant.

Working principle of spiral separators The ore materials are separated by the specific difference of gravity force, inertial centrifugal force, flow force, and surface friction of the light and heavy ore particles in the downward flow along the spiral tube slope. Generally speaking, the movement of the slurry flow on the spiral concentrating tables surface produces two directions, one is the longitudinal flow which rotates swiftly around the vertical axis of the spiral chute and down along the chute surface, which is called the main flow, the other is the transverse flow which rotates around a balance layer of the ore flow itself, called transverse circulation flow or vice flow. Under the comprehensive action of longitudinal main flow and transverse circulation, the mineral particles on the surface of spiral classifier move differently along longitudinal and transverse direction due to different density, particle size and shape, and settle at the bottom of the spiral groove in different time and speed, so the mineral particles are stratified according to density and particle size.

Stratification is the first stage of the separation process, which is basically completed after the first processing circuit of the spiral separators. After delamination, the light mineral particles in the upper layer flow to the outer edge of the spiral separator machine gradually, while the heavy mineral particles in the lower layer are affected less by the longitudinal main flow and move to the inner edge gradually. In this way, the layered particles are divided again, which is the second stage called zoning, completed after series ( 3-5 times ) sorting process. After the above two stages, the ore intercepting trough and the ore receiving hopper discharge the different grade separation products from the clay trough, and the separation process is completed.

The grain size distribution rule along the cross-section of the wet spiral separator is as follows: under normal ore-feeding conditions, more than 70% of the ore particles are concentrated in the middle of the spiral concentrator beneficiation area; About 20% of the ore grains are located at the inner edge of the chute; Less than 10% of fine ore grains are near the outer margin.

wet grid ball mill

wet grid ball mill

Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. The size of ore shall not exceed 65mm and the best feed size is under 6mm. The effect in this job is better than coarse grinding. Grid ball mill consists of the shell, feeding part, discharging part, main bearing, lubricating system, driving system and other parts. There is wearing a liner inside the shell, and both ends of the shell are provided with a flange. The end cover of the mill is connected with the flange plate. The feeding part consists of the head, trunnion and feeding device. The discharge part includes the grid plate, head, and discharge trunnion.

Wet Grid ball mill is mainly used for mixing and grinding materials in two types: dry grinding and wet grinding .It has advantages of fineness uniformity and power saving. The machine uses different types of liner to meet different customer needs. The grinding fineness of material can be controlled by grinding time. The electro-hydraulic machine is auto-coupled and decompressed to reduce the starting current, and its structure is divided into integral type and independent type.

Compared with similar products,Wet Grid ball mill has the characteristics of low investment, low energy consumption, novel structure, simple operation, stable and reliable performance. It is suitable for mixing and grinding ordinary and special materials. The users can choose the right type, liner and medium type by considering the specific gravity, hardness, yield and other factors. The grinding medium is Wet Grid ball.

1.The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The main body is a long cylinder made of steel. The cylinder is provided with an abrasive body, and the steel lining plate is fixed to the cylinder body. The grinding body is generally a steel ball and is loaded into the cylinder according to different diameters and a certain proportion, and the grinding body can also be used with a steel section.

2.According to the particle size of the grinding material, the material is loaded into the cylinder by the hollow shaft of the wet grid ball mill feeding end. When the ball mill cylinder rotates, the grinding body acts on the cylinder liner due to the action of inertia and centrifugal force and friction. It is carried away by the cylinder. When it is brought to a certain height, it is thrown off due to its own gravity. The falling abrasive body crushes the material in the cylinder like a projectile.

3.The material is uniformly fed into the first chamber of the mill by the feeding device through the hollow shaft of the feeding material. The chamber has a step liner or a corrugated liner, and various steel balls are loaded therein. The rotation of the cylinder generates centrifugal force to bring the steel ball to a certain extent. The height drops and then hits and grinds the material. After the material reaches the rough grinding in the first bin, it enters the second bin through the single-layer partition plate. The bin is embedded with a flat liner with steel balls inside to further grind the material. The powder is discharged through the discharge raft to complete the grinding operation.

The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill. Whether the crushing requirement can be achieved depends on whether the grading of the steel ball is reasonable, mainly including the size of the steel ball, the number of ball diameters, and the ball of various specifications. Proportion and so on.

The ball mill is composed of the main part such as a feeding part, a discharging part, a turning part, a transmission part (a reduction gear, a small transmission gear, a motor, and electric control). The hollow shaft is made of cast steel, the inner lining can be replaced, the rotary large gear is processed by casting hobbing, and the barrel is embedded with wear-resistant lining, which has good wear resistance. The machine runs smoothly and works reliably.
