KISA Discharge systems for bulk material

General

The KISA dosing units are either volumetric or gravimetric (calibratable) and consist of a slide valve and a dosing belt.

Combined dosing units

Electric gates, with and without dewatering

Dosing conveyors

Flat slide gates – and emergency shut-off gates

Blending units

Trucker self-service for loading

KISA – combined feeding units are used for difficult-to-convey bulk material. Gate and conveyor are assembled to one unit by a connecting box. Vertical, bolted blades below the gate bottom provide the bulk material down to the feed belt and so prevent an uncontrolled breakaway. The gap between gate casing and connecting box – when opening the gate – is closed by long sealing bars, bolted on the face sides of the bottom plate. So, down to the discharge head of the feeding belt, a closed material flow is realized by KISA feeding units.

The KISA feeding unit always allows a maximum open cross section of the gate. So bridging and the resulting hang-ups will be avoided.

A column of bulk material is developing above the conveyor belt. A controlled dosing and discharge of the bulk material is possible by choosing belt speed and given layer height.

KISA combined feeding units have the smallest possible mounting height and are designed self-supporting up to 2 m center distance of conveyor belt.

All sheet parts are galvanized and bolted.

Optionally you can combine KISA feed belts with all KISA slide gate series. Also triple combinations, as for example, feed belt / drainage gate / emergency gate are possible.

The clearance width of the gate should be at least as big as the feed belt width. So the material flow remains undisturbed and high abrasion can be avoided. A material control flag is signaling the status “EMPTY“.

KISA – electrically driven slide gates are constructed in modular design. All frame parts are bolted to each other and each single part can be changed in case of wear and tear. The drive is positioned in the center and protected between the side bar sheets. The gate bottom is declined considerable and so presents the premise for a good drainage of wet bulk material. All sheet parts are hot galvanized. Drive shaft, pinion, rack and slide rails are galvanic plated. Installed limit switches mark the positions “Open” and “Closed”.

KISA – electrically driven slide gates are equipped with engine brakes. In case of volumetric loading, we achieve by this means 100 % reproducibility of the open cross section, dependent of the running time.

In case of closed KISA – electric gates a drainage for wet, standing column of bulk material will be achieved. This is done as well by installed draining screens, as by the adjustable gap, between gate bottom and casing. Both of the water flow will be provided over the declined gate bottom to the gutter below the gate and can be drained further by customary plastic pipes at site.

For less flow rates however, as for example for blending, the KISA type SD is suitable. A quadratic cross section is formed in every state of opening and so there are optimal flow characteristic for the bulk material.

Dosing belts

KISA dosing belts are used for gravimetrical as well as volumetric dosing of bulk material. The design is modular, as for the gates i.e. every single part is bolted and can be changed in case of wear.

Discharge capacities up to 2500 t/h are possible. The newest technology of frequency converters allows absolutely continuous control for any range So, for example the capacity control of the KISA Standard belt D800, covers the range of 0–600t/h.

The KISA loading terminal EKV-1 enables the self-service loading by the trucker. The big keyboard and an easy to read, reflexion-free display asks for the following input:

quantity to load in tons, for example: 29,3t

with or without trailer (with trailer a second quantity has to be defined)

Start – push button

After a programmable delay, the gate valve opens and automatically starts the dosing conveyor respectively. The loading will be volumetric, depending from opening width of gate valve and the flow rate of belt conveyor and the processor-calculated time, respectively.

A high standard of precision is reached by the high time resolution and the exact, mechanical reproducibility of KISA dosing units.

Blended grain size loading

Software MEDOS

Software MEDOS

Our software MEDOS, especially developed for blended grain size loading, allows to create and manage extreme varying blends. By calling prior deposited recipes (compositions) and the loading quantity, can be started at once.

A unique menu guiding and the clearly visualized MECOS are the warranty for an easy to handle operation.

MEDOS can operate volumetric, as well as gravimetric.

The handling is possible optionally by a commercial quality PC or a touch screen PC with protection IP55 for outside operation.

Self-service loading for truckers, here are also possible with corresponding card readers, mostly by transponder cards.
