DetailLS screw conveyor is according to JB/T7679-95 standard design and manufacture, screw conveyor is the replacement of the GX screw conveyor. LS screw conveyor is a closed tube using rotating continuous spiral vane with push material conveying machinery, cement is mainly used to transport cement, fly ash and mineral powder and other powder, particle shape, such as material, unfavorable delivery big viscosity, easy to agglomerate, fiber and other raw materials。
1. Made of high quality seamless tube, and the overall rigidity, without dust leakage, safe and reliable。
2.s made of a forming spiral blade, the pitch distance error is small, high precision dynamic balancing。
3.LS screw conveyor double pitch design, reduce material in conveying the compressed degree。
4.USES the high quality reducer, heavy-duty design, with large torque, low noise, no oil leakage, long life characteristics。
5.. With good quality famous brand bearing ensure the high efficiency of delivery。
6.LS screw conveyor ball hinge, pipe, flanges, flange interface to connect a variety of ways。
7.Common diameter of 165, 219, 273, 323, 407, LS screw conveyor of a large number of stock, the size and Angle can be made according to customer's requirements。
Screw conveyor from 200 mm to 500 mm in diameter, with a total of five kinds of specifications, the length from 4 meters to 70 meters, one every 0.5 meters, conform to the standard model selection of the nominal length, special needs can be chosen in matches when put forward separately. < BR > screw conveyor drive mode can be divided into two kinds: < BR > - C1 know-how for the screw conveyor length less than 35 m, single-ended driver.
- C2 know-how for the screw conveyor is greater than 35 m, double drive。
According to the bearing types are divided into screw conveyor in the middle：
M1 - for the rolling bearing, using 80000 type sealed bearing, axis cover otherwise dustproof sealing structure, commonly used in is not easy to come on, don't gas or oil to material there is pollution, good sealing effect, hanging bearing life is long, conveying material temperature of 80 ℃ or less (when you order it doesn't indicate).
M2 - made sliding bearing, a dust-proof sealing device, commonly used in conveying material temperature is high (> 80 ℃), or transporting materials in liquid。

The machine layout:
A screw conveyor are usually made of screw machine ontology, in and out of the device, driving device composed of three parts。
Screw machine ontology header section, the middle section, the tail section of three. Under normal circumstances, when the factory assembly, the middle section according to the length of the ordinal arrangement, in the middle of the longest section close to the head section, the middle section of the same length, get together, if you have special requirements, is in order when the order is given。
In the first section is equipped with a bearing to bear axial force, in the middle section and the tail section is equipped with spiral shaft bearing, in addition, in the tail section is equipped with the axial movement of the radial bearing to compensating the error of the screw axis length and adapt to the change in temperature. Spiral surface forms a spiral method (S) and entity belt type spiral method (D) two kinds. The flange connection between the screw axis, ensure the compatibility of the connecting shaft, easy to maintenance。
Machine cover is tile type and cover buckle clamped on the chassis, if need to improve the sealing performance, users can cover between the casing and waterproof canvas。
Machine cover is tile type and cover buckle clamped on the chassis, if need to improve the sealing performance, users can in itself into the feed port, discharging device, square discharging mouth, hand push type discharging mouth, the rack type discharging mouth four. By the user in the use of the open welding on the body. Decorate material into and out of mouth position should be paid attention to ensure material to the end of the distance, at the same time avoid mouth with suspension bearing oiling cup, casing flange connection, the base of a collision。
Driving devices have ZQ series reducer + Y series motor, YTC two geared motor。
According to the screw conveyor drive mode can be divided into two kinds：
C1 method - the captain of the spiral degree is less than 35 m, single-ended driver。
C2 method - screw machine is more than 35 m, double drive。
According to the spiral machine suspension bearing types are divided into in the middle：
M1 - for the rolling bearing, using 80000 type sealed bearing, axis cover otherwise dustproof sealing structure, commonly used in is not easy to come on, don't gas or oil to material there is pollution, good sealing effect, conveying material suspension bearing long life, temperature of 80 ℃ or less (when you order it does not indicate)。
M2 - made sliding bearing, a dust-proof sealing device, commonly used in conveying material temperature is high (> 80 ℃), or transporting materials in liquid。
Type LS screw conveyor of all kinds of fashion:
| Parts of the | Fashion symbol | According to the content |
| Screw type | S | Helical surface with entity type screw, the pitch is equal to 0.8 times the diameter of the |
| D | With belt type screw, the screw pitch is equal to the diameter | |
| Hand push type discharging type discharging mouth tongue bar | Left installation | By the screw head quarter to look the tail section, pull board pulled to the left |
| The right outfit | By the screw head quarter to look the tail section, drawing board to the right start | |
