High efficiency low price spiral sand washing machine for building material

LSX spiral sand washing machine

LZZG spiral sand washing machine is mainly used for many sandstone industries such as: sandstone factory, building work site, hydroelectricity dam, glass manufacture, oil well development. The machine is specially designed for sandstone and quartz sand company to wash, separate, and classify and dehydrate.

Structure Description

This machine is a single screw sand washing machine, and it contains the following parts:

The Transmission Device: It is composed of the electric motor, big and small belt pulleys, triangle belt and gear reducer.

Gear reducer: speed ratio i=68.61, a whole sealing oil bath type. The gear is steel cylinder helical gears. The materials of the gear reducer are HT20-40 with industrial pad liner(δ=0.5mm). The liner is smeared withfluid sealant. The reasonable design of the gear and the gear reducer ensures the accuracy of transmission.

Screw arbor:Screw diameter D=920mm, Thread pitchS=445mm, HeadZ =1, Cylinder number N=15.5. The materials of screw blade is Q235A, δ=8mm armor plate jointed continuously to the hollow shaft. The screw of each thread pitch iscomposed of six liners. Liner materials are high manganese cast steel (ZGMn13). The screw liner is connected by bolt, nut and screw blade. Hollow shaft is seamless pipe (219X22) which ensures intensity and rigidity. On the both side, jointing ring flange which is connected to lug and under-part bearing respectively. This structure meets the demand of sand to wash, separate, and classify and dehydrate fully.

Under-part bearing: the lower extreme of screw arbor is under the waterline of trough, supported by the under-part bearing. All axial force of screw arbor is supported by rolling bearings from gear reducer. Under-part bearing does not support axial force, but radial force. Under-part bearing is installed the outside of trough’s undersurface.

Tail shaft is connected to the screw arbor. It rotates in the flexible rubble sealing washer when works. Thackeray washer rotates with tail shaft, which still sealed well after under-part bearing’s long-term use.

Trough: It contains shell, input devices, right weir plates and left weir plates.Trough is steel plate jointed into water tight structure. Right and left weir plates and input devices are connected by bolt, nut, and grower washers. Right weir plate and left weir plate&=3(mm)rubber sheet for sealing.

On the bottom of trough, it installs sheet bending machine on one side which keeps a suitable clearance with the out edge of the impeller in order to move particles forward. Another side is gutter used for discharging moisture from sand.

Overflow platecan be adjusted; upgrade one or two weir plates, can curtail the valid length change the admission velocity of washing water, can increase working head and change overflow speed, getting rid of granule according to the demand of classification.

Wire plates can provide compensation when trough’s location tilts by the mistakes of assembling and installment.

The sand needed to wash gets into the washer from input devices. It has no inside and outside baffle plate, can control the material flow effectively and reduce velocity of flow. When input devices install at the correct location, sand can get into the washer evenly, and reduce backset to keep fine materials.

Working Principle

This sand washershould be installed with an angle of 15 degree,under the water tub, three weir plates form the sediment pool, the screw head is immersed in this pool, the screw is driven by electric motor through reducer rotating continuously, the fresh water is feeding from porous plate at bottom of sediment pool, this machine have three functions of washing, dewatering, classifying.

Washing:

The sand is feeding into the sediment pool from the feeding box, with the help of rotating screw blade, the sand is turning, rolling and grinding each other to eliminate impurity and water-air layer around sand to facilitate de-water. The fresh water rising current from the porous plate carries foreign matter to water surface and overflow the weir plate, to finish washing processing.

De-watering:

The sand with bigger density is sunken down to tub bottom, the screw blade push this sand upwards, when passing through upper tub of proper length above water level, the water is draining into sedimentpool from another drainage ditch, the de-watered sand is out from the discharging opening.

Classifying:

Material classifying is realized by overflowing the fine particle that does not meet the standard requirements. The controlling method is adjusting height of overflowing weir and adjusting speed of screw.

Specifications:

Features:

1. Three functions: cleaning, dewatering and grading.2. Cleaning and upward conveying at the same time.
3. Low water consumption; durable.
4. Impellers use wear resisting plate or polyurethane material, reduce the running cost.
5. Designed according to low volume, low investment.
6. Capacity of screw sand washer is above 100t/H, effectively control the sand washing loss.

Driven by electric motor and decelerator, the impeller of sand washing machine moves in a circle in the water groove, thus make the sand or slag pellets mixed, overturned, cleaned and discharged in the water groove.High efficiency low price spiral sand washing machine for building material There is little loss for medium-sized and fine sand and stone powder. Sand Washing Machine The grade and the fineness of the sand for construction after being washed can be up to the national standards, such as sand for construction and cobble and broken stones for construction. There are no other wear parts except the screen mesh. Sand Washing Machine has longer service life and little maintenance chance.
