ZKSJECO · Qingdao, China · From bag to batch
As single machines or one complete line, engineered around your material and process. For powders and bulk materials that are dusty, sticky or abrasive.
Photo Automated batching line · built by our team
Proven drives and mixing principles. Wetted materials and connections chosen for your duty.

Core machine
Our core machine is the twin-shaft batch mixer, built in our works for dry, damp and sticky mixes, and in service on fly ash, chemical and steel-plant duties since 2019. Planetary and tilting intensive mixers are supplied as part of a line.

Tell us your material and your process. We engineer the section or the whole line, build it and commission it. All industries

Stabilization of fly ash, hazardous waste, sludge and contaminated soil. 80+ projects since 2019, new lines and upgrades.
Environmental
Several powders from their silos, weighed to a recipe, conveyed and mixed, run from one control room. For any industry.
Dosing and weighingShredding, crushing, conveying and dust collection for ash recycling and industrial waste pre-processing.
Bag unloading, dosing and corrosion-resistant mixing for salts, detergent powders and additives.
Bulk bag unloading, conveying and mixing for plant dust, fluxes and ore fines.
Building materials, minerals, water treatment chemicals, battery materials, or a material we have not seen yet. An engineer looks at it first.
From fabrication to commissioning, the interfaces stay with us.



Why ZKSJECO
Tell us the material and the process; our engineers work out the line. New materials and industries we have not served yet are welcome, and that is often where we are most useful.
Twin-shaft mixers, shredders, dust collectors, rotary valves and weighing screws are made, assembled and tested in our workshop in Qingdao. Factory audits and witnessed tests are welcome.
Bag unloading, crushing, conveying, dosing, mixing, dust collection and PLC controls under one contract. The interfaces between machines are ours to get right.
More than 110 projects since 2019, over 70 of them stabilization lines. Fly ash is dusty, sticky and abrasive at once, and the same engineering carries over to other hard materials.
ISO 9001, ISO 14001 and ISO 45001 management systems, and CE marking on export equipment where the destination requires it. Utility model patents in China.
A 12-month warranty, spare parts in stock, 24-hour technical support and engineers who come to site.
After-sales and service
Our engineers answer by phone, email or video call. You get a first answer within 8 hours and a written one within 24.
We supervise installation, commission the line and run it with your team until it meets the acceptance terms. If something goes wrong, we aim to be on site within 48 hours in China and within about 5 days overseas, visas and travel permitting.
Spare parts are kept in stock and supplied for the life of the equipment. Paddles, liners and seals are bolted on, so they are changed on site; we suggest one set of wear parts with the machine.
