In cases where uniform winding is a major consideration the width of the drum may be reduced to accommodate only 2/3 turns of cable in each layer. monospiral the monospiral drum is used for all sizes and lengths of cable, and voltage upto 11 kv. The cable drum is fully ventilated and the derating factor is not high. The number of layers is unlimited but the overall diameter of the drum is limited by the clearance available. the width of the drum is equal to cable diameter plus 5 mm. parallel the parallel drum is used for all sizes and lengths of cable and for voltage upto 35 kv. The width of a parallel drum varies between 0. 8 m and 5 m. This drum is also popularly known as barrel type drum. The winding of cable is uniformly guided by a winding device.

Spring driven cable reeling drums are driven by special helical springs. Generally springs have a limited life. Due to continuous winding and unwinding operation normal fatigue sets in. If the best material is used, the springs will show signs of fatigue after approx 40,000 to 50,000 movements. This metal fatigue can lead to breakage of the springs. Any small oscillation of the spring to be considered as one movement. there are two types of spring drums. In one type the springs are mounted on the drum shaft and tensioning is achieved by rotation of the drum body. In the other type, the springs are accommodated in a separate housing i. E. A spring motor. The spring motor facilities easy spring replacement, without disconnecting / removing the trailing cable. for your specific requirement please fill up the attached data sheet and send it to us. hose reeling drum electro zavod hose reeling drums are driven by springs. In the hose reeling drum, in place of slipring unit, a rotary valve is fitted.

Magnetic separation is a continuous process by which magnetic material is separated from non-magnetic material. The mixture of magnetic and non-magnetic material is passed through a strong magnetic field. Magnetic material is magnetized and gets attracted to the surface of the separator and is discharged in a chute. the efficiency of the separator depends upon the strength of the magnet and the speed of the conveyor. The length of the magnet is designed such that the magnetic material is in the magnetic field for a period of 0. 4 to 0. 5 secs. Strontium ferrite permanent blocks are used in the magnet assembly to achieve a surface gauss of 2500. For special application nd feb magnet blocks are used to achive higher magnetic strenght. the gap between the magnet and the conveyor is adjustable. Lower the gap, better the separation efficiency. Individual drive is used for the separator and the conveyor. Adjustable stainless steel splitters are provided between the two chutes. Vibrating feeder with two unbalance motor is also provided, which ensures that the material spreads across the belt to achieve better separation. We can supply belt type separators for a belt width of 650 mm to 1600 mm. operating principle the mixture of char and sponge is passed under the magnetic separator by a conveyor. The mixture is fed on to the conveyor evenly by the help of a feeder. Under te influence of the magnetic field the magnetic material is attracted upwards, towards the magnet face. The attracted material is carried along the cleated belt of the separator and is continuously discharged in the mag chute. The char is carried by the bottom conveyor and discharged in the non mag chute. manufacturing range 650 mm belt width upto 1600 mm belt width special features 1. Individual shaft mounted geared motor for top and bottom conveyor. 2. Vibrating feeder with two unbalance motors. 3. Dust covers with inspection windows. 4. Adjustable magnetic strength. 5.

We offer high quality overband magnetic separators, suspension magnets & magnetic pulleys

Electro zavod overband magnetic separators are available in two basic designs - in line & transverse in line models are suspended along the main conveyor belt. The separator is mounted at an angle as shown for better performance. The belt of the separator travels in the same direction as the main process conveyor with a speed which is equal or greater than the main burden speed. The tramp is discharged away from the conveyor belt in the direction of travel. transverse separators are suspended at right angles to the main conveyor. It can be installed anywhere along the conveyor line. The tramp is discharged at right angles away from the conveyor. electro zavod suspended magnets these operate most efficiently when they are placed at an angle over the conveyor head or over the discharge point of a vibratory feeder. In such cases, the magnets can remove more tramp from deeper burdens even at higher conveyor speeds since the burden loosens up and fans out. In cases where the magnet cannot be installed at an angle over the discharge point, it may be suspended parallel to and above the conveyor belt. selection of the proper magnetic separator for any application requires very careful evaluation of all operating conditions and separation objectives. The magnetic field configuration of any magnetic separator, regardless of type, should profile the conveyor belt for maximum tramp removal. To help proper selection, to enable us to recommend the most efficient and economical magnet, the following information is required- *belt width * belt speed * belt incline * troughing idler angle * burden depth * capacity in tph * material size & density *minimum & maximum tramp metal size * desired location of magnet * head pulley material & diameter *type of separator (a) suspended (b) in line (c) transverse in technical collaboration with almhults el-mek ab of sweden

Operating principle of magnetic drum separator ez drum separators are primarily designed and manufactured as low field intensity separators. They have an open magnetic system with the magnetic poles located in one plain. Low field intensity separators are employed for separating iron particles from bulk material whenever foreign iron disturbs the subsequent process sequences. It is also used for removing or enriching strongly magnetic content of dry minerals. the most widely used application of drum separators is by deflection separation in which the bulk material is fed onto the top of the drum. This must be spread evenly over the entire width in order to ensure optimum utilisation of the drum. The use of a vibratory feeder is appropriate for feeding the material tangentially onto the drum. This operating procedure ensures minimum wear to the outer drum and guarantees constant-speed application. At normal feed speed of 0. 2-0. 3 m/sec. Using vibratory feeders, the material is spread and distributed quickly over the drum, which rotates at a speed of 0. 6-0. 8 m/sec. The material is reduced to 1/3 - 1/4 of the feed layer height. on permanent drum separators rectangular magnetic blocks generally made of sintered hard ferites are radially magnetized and mounted on a soft iron plate. the magnetic drum is connected to a rigidly fixed shaft, the position of which is adjustable. The outer drum made of high-grade steel or manganese steel rotates around the axis supported on roller bearings. we can also offer high intensity drum separator.
