The bearing bears the full load of the machine; therefore, the outstanding smoothness has a great connection with the bearing life; it directly affects the service life and operating rate of the machine; therefore, the smooth oil to be written needs to be hygienic; the seal needs to be outstanding; The primary oil filling part of the machine (1) transform bearing (2) roll bearing (3) all gears (4) movable bearing, sliding plane.
2. It is necessary to check the wheel of the new equipment simply and loosely.

Slime dryer features:
1. The boring machine has strong anti-overload capability; the disposal amount is large; the fuel consumption is low; the boring cost is low,
2. The downstream drying method is adopted; the flue gas and the wet material enter the boring machine from the same side; the high transpiration intensity can be obtained by using the high temperature flue gas; the outlet temperature of the boring machine is low; the heat power is high;
3. The operating parameters can be changed according to the different material properties; the material can form a stable and complete broken fabric curtain in the boring cylinder; the heat exchange is more abundant.
4. New feeding and discharging equipment; eliminate the appearance of blockage, non-continuous, uneven and returning of the drum dryer; reduce the load of the dust removal system,
5, the new internal structure; strengthen the cleaning and heat conduction effect of the scattered materials; eliminate the sticky appearance of the inner wall of the cylinder; adapt to the moisture and viscosity of the material,
6. The boring machine has finished “zero horizontal thrust”; it greatly reduces the wear of the retaining wheel; the cylinder operation is stable and firm.
7. The boring machine adopts “aligning wheel-type wheel equipment”; the cooperation between the roller and the roller ring is permanently linear; then the wear and power loss are greatly reduced.
8. The product size and moisture can be manipulated according to the user's needs; the moisture of the product can reach 8% or less when the coal slime is dry; the particle size can be controlled by a linear sieve below 8mm.
The use of slime dryer:
Coal; is a kind of flammable goods conveyor. Coal slurry; under the premise of high temperature; also simple incineration cement production process. Reverse type slime dryer; new type of thermal communication equipment using flat plate to dry materials; Low energy consumption, stable functions and other strengths. It is also suitable for drying and precipitation of other materials. It is used in a wide-scale mobile crusher. In the case of ensuring the quality of the dried coal slurry is unchanged; the first-stage dry area is cooled by downstream high temperature; under high humidity conditions; Temperature 43 0 °C; heat mass transfer with the slime; remove most of the water; ensure that the calorific value of the slime does not change; and is not easy to catch fire, the secondary drying zone is countercurrent drying; room temperature 300 °C; is a high-yield water removal zone; in the reverse drying process; to ensure that the surface of the slime does not coke, the three-stage dry zone is the normal drying zone; the indoor temperature is 120 °C -210 °C; it is the crushing equipment in the drum Repeated pulling, hitting, and scattering; downstream drying, four-stage drying is to remove water by high-temperature hot air flow with negative pressure under the effect of air; high exhaust zone; room temperature 60 °C -80 °C cement production line Through the above operation, the slime is added after drying than the heat value before drying; the water is boring within 8%; the real effect of energy saving and consumption reduction is linear vibrating screen.
Slime dryer operating principle:
The slime itself has high humidity and high cohesiveness; in the process of boring, the wet coal slurry enters the slime dispersing equipment via the belt conveyor; after the block coal slime that is quickly disintegrated enters the boring machine with negative pressure The following operation areas: First, the guiding area; wet coal slurry enters this area and is heated by agitation after hot high temperature negative pressure hot air; the slime is copied under the large-angled copying board; It is introduced into the next working area, and the second is the finishing area; the wet coal slurry is copied from the board in this area to form the curtain condition; when the material falls, it is easy to form the surface of the bonding drum wall; in this area, the equipment is designed with cleaning equipment; The equipment can quickly sort out the slime of the bonded cylinder wall; in this process; the cleaning equipment also has a crushing effect on the agglomeration of the material ball; then the thermal AC area is added; the power of heat and mass transfer is improved; the boring progress is improved Rate, the third is the slanting slab area; this area is a low temperature boring area; the slime has a low moisture slack in this area; this area has no cohesive appearance; the product reaches the required water demand after heat exchange; Movement into the final discharge District, the fourth is the discharge area; the boring main drum does not have a copy board in this area; the material rolls in this area and slides to the discharge opening; the entire boring process of the cement plant equipment is completed.
