VST-Type Vibrating Screen-Chute with Sifter
Purpose (function): linear uniform feeding (transport) of the product (stone, coal, lime, etc.) from the collecting hoppers at any vehicle or dosing equipment (conveyor, feeder, bucket conveyer, etc.) of the process chain, as well as separation of fine fraction (up to 40 mm).
Operating principle: consists of a chute with a mounted sifter under the unloading part (wedge-shaped teeth with corners). Size of fractions sifted is adjusted through the longitudinal movement of the top of the sifter chute. The opposite side of the chute is restricted to a tailgate, to the wall of which two shakers are attached. When the vibration motor is on, the oscillations are transmitted from them to the chute and sifter, stimulating the longitudinal movement of the material (product) on the chute and separation of fine fraction via the sifter. To reduce the vibration loads, the chute is mounted on springs-absorbers. Device operating mode – cyclic/continuous.
Vibrating Feeder — VFT-Type Chute
Purpose (function): linear uniform feeding (transport) of the product (stone, coal, lime, etc.) from the collecting hoppers at any vehicle or dosing equipment (conveyor, feeder, bucket conveyer, etc.) of the process chain.
Operating principle: vibrating feeder-chute by a flange at the top of receibing hopper is attached to a collecting hopper filled with material. When the vibration motor is on, discharge of material in the chute starts. To reduce the vibration loads, the chute is mounted on springs-absorbers. Device operating mode – cyclic/continuous.
Purpose (function): weighing of an exact batch (portion) of the product capable of adjusting speed of product discharge from the hopper.
Operating principle: mounted on strain gauges, receiving hopper of the device allows weighing products coming into it. After product loading into the hopper, the device is immediately ready for subsequent discharging of a batch (portion). Vibrochute of feeder-batcher discharges a batch (portion) of the product with the help of two vibration motors. Vibration motors provide linear product displacement on the chute. The product discharge rate can be controlled through the unbalance of vibration motors’ eccentrics.
LS-Type Lime Slacking Drum
Purpose (function): calcined lime slaking.
Brief operation description: Lime slaking drum is a horizontal cylindrical drum pos.3 leaning with its bandages pos.5 on two pairs of carrying rollers pos.14. The drum is rotated by a drive consisting of an electric motor pos.8, gear pos.7 and gear key pos.6. Calcined lime enters the tail of the drum through a loading device pos.1, equipped with a dosing valve pos.2.
For lime slaking, ammonia water and rinse are supplied into charging device through the branch pipe.
On the inner surface of the drum, along the helical line blades pos.4 are welded which form a quadruple threaded screw from the position of loading to the position of unloading. At the drum discharging, there are six reinforced pockets for bailing the lime milk. In the fixed housing pos.9, a sieve cylinder pos.10 with screw bands pos.11 is rotating. Through a sieve, the lime milk passes into the hopper and is removed through the branch pipe, and incompletely burned material lime, by means of screw, is output into the second hopper and removed through the branch pipe. On the top of the fixed housing pos.9 there is a pipe pos.12 and a retarder pos.13 for removing vapors generated during lime slaking from the apparatus.
Lime Milk Mixer, MLM(v)
Purpose (function): intended for creating a stock of lime milk, mixing, leveling of density and its slaking.
Operating principle: lime milk is fed through the branch pipe into the mixer and stirred by the mixing device.
