Rotary Dryer Application&Lifting Plates Classification

Rotary dryer application:
Rotary dryer mainly used for drying chemical, construction material, metallurgy granule and powder, has compact structure, well-making, high efficiency, low energy consumption, easy transportation advantages.

Rotary dryer inner structure:
In order to make the material distribution over the cross section of the drum uniformly, make sure each part connect the drying medium well, there are lifting plates inner the drum cylinder. Lifting plates can be classified the following types:

I. Lift-type lifting plate: suitable for big block material or easy bonding on the drum cylinder material.
II. Four grid type lifting plates: suitable for high density, not brittly or difficult to disperse material. The drum cylinder is divided into four cells by lifting plates, shown mutually unintelligible fan shape working room, the connect area between material and hot air is bigger than lift-type lifting plates, besides increase materials filling rate and reduce materials falling height as well, thus achieving the effect of reduce the dust loss amount.
III. Criss-cross or frame shape lifting plates: suitable for deal with brittly and disperse small size material, make the material distribution over the drum cylinder uniformly.
IV. Sleeve drum type lifting plates: also called rotary drying machine duplex transfer heat(or radius heating) lifting plates.
V. Sub-grid type(fan shape) lifting plates suitable for deal with easy to cause the powder flying very fine particles materials. Once feeding the material then accumulation on the grid board, when the cylinder rotation, turning the materials and connecting to the hot air constantly, as the falling height reduced, reduce the possibility of the dried material carried away by gas.
All the above type lifting plates can distribution all the drum cylinder, in order to make the material transport to the lifting plates fastly and uniformly, you can install spiral shape guide plate away from the feeding port 1-5m, avoid the wet material accumulation on the drum cylinder. Because the dried material can be take away easily by the waste gas, so, no need install any lifting plates away from the discharging port 1-2m.

Sand making production line brief introduction

Sand making system composed by feeding system, crushing system, screening&transport system.

Sand making line is special equipment for produce construction sand and stone, save 50% energy than the traditional sand making machine. Suitable to deal with the materials like rock, gravel, river pebbles, etc. Output the products' size according to the standard building sand requirements. The products outlet from the sand making line has features of sand size uniformity, high strength&pressure resistant, reliable performance, reasonable design, easy operation, high efficiency,etc; Much more suitable than natural sand, common hammer sand machine as well as higher quality.
Property introduction:
Sand making line with high degree of automation, low cost, high efficiency, energy-saving, high capacity, eco-friendly, easy maintenance; The outlet products with uniformity size, good particle size, level with the rationale can completely meet the national standard requirements.
In addition to daily maintenance&stop or start the machinery, stone making production line equipment almostly no need people operation. AS in gravel making equipments process flow design, each level crushing equipment matching reasonable and with compact space layout, so, they has small footprint, low cost, high profit, good quality aggregates, low powder outlets, with advanced electric control operation system, make sure the completely line discharge smoothly, reliable working, easy operation, high efficiency&energy-saving.

magnetic separator common troubles analysis

1.The reasons of magnetic separator motor with overheat and uncommon noise:
a.Bearings with poor lubrication or abrasion serious;
b.Fan blades out of its' positionor abrasion;
c.Switch line with bad connection or off line run single phase;
d.Voltage is too low.
2.There is an unnormal sound when the magnetic separator working,maybe the drum cylinder was stuck by obstacle, even lead to the drum cylinder can't running, the bottom frame shaking. At this time, you should shut down for maintenance, slove the problems.
3.Reducer with overheat reasons:
a.Shorting of oil or poor oil quality;
b.Gear and worm pole abrasion serious or meshing badly;
c.Bearings with poor lubrication or abrasion serious.
4.Magnetic separator magnetic field strength becomes weak reasons:
a.High temperature;
b.Sun exposure;
c.Acid corrosion.
So, you can use a gauss meter to measure the magnetic field strength.

Jaw crusher maintance tips

Jaw crushing machine maintenance:

1.Stop jaw crusher working per several months, checking the machiney. When start or stop the jaw crusher to deal with your raw material, you should pay attention to the jaw crushing machine abrasion condition regular, the abrasion parts: center feeding pipe, cone hat, impeller, liner, wear-resistant block wear degree, replacement the wear serious parts, repair them. As well as replace the parts according to the organic technical parameters(include the model, weight,dimension,etc).

2.Checking the belt regularly. Belt is indispensable in the jaw crushing stone production line, it provide driving power for the plant. Adjust belt tightness degree regular, make sure belt be forced uniform. If the jaw crusher with two motor, each side belt length should as consistent as possible, any abrasion serious should be replaced timely.

3.The equipment spare parts lubricating. Add some grease per 400 hour working time; Every 2000 hour working time, open main bearings and clean it; Generally after 7200 hours working time, you should replace new bearings.

Besides, to make sure the jaw crusher working normally, in addition to operate the jaw crusher correct, maintenance must be planned, include daily maintance.
