Equipment scope for the cement industry

Filters, fans, filter bags, cages, and conveying equipment matched to each process point in a cement plant

A cement plant does not have just one filtration need; from the crusher to the raw mill, from the kiln/preheater line to clinker cooling, and from the cement mill to silo and packaging, every point differs in dust load, temperature, flow rate, and maintenance risk. Hantech Filter therefore addresses filter housings, fans, filter bags, cages, pulse systems, rotary valves, screw conveyors, elevators, air slide fabric, and conveyors together on a process-by-process basis.

Process filtration, fans, and spare parts scope for cement plants

Process-based cement filtration

The correct product for raw meal, clinker, cement, coal, silo, and packing lines is selected based on flow rate, temperature, dust type, and emission target.

Equipment groups used in cement plants

ID fan / kiln exhaust fan

High flow rate and pressure requirement at the main draft points of the kiln, preheater, and raw meal system.

Raw meal system air handling equipment

Flow/pressure balance together with the raw mill, separator, and system filter.

Clinker cooler fans

High-temperature and wear control at cooler cells, shell cooling, and cooler exhaust lines.

Cement mill fan

Stable flow rate, low vibration, and energy efficiency for the mill filter and separator line.

Coal mill fan

Coal dust and temperature-controlled operation together with antistatic/safety scope.

Local dust collection air handling equipment

Local extraction solutions at crusher, transfer, packaging, silo, and loading points.

Product families we supply for the cement industry

Baghouse filter systems

Filters for clinker cooling, raw meal mill, cement mill, coal mill, silo, packaging, and transfer points.

Filter Bags

Polyester, antistatic PE, aramid, PPS, P84, PTFE/ePTFE membrane, and fiberglass options are selected based on temperature, humidity, alkalinity, and emission target.

Filter cages

Galvanized, cataphoresis-coated, silicone-coated, and stainless steel cages; venturi, wire count, diameter, and bag compatibility are checked together.

Pulse jet valves

Bag cleaning via diaphragm valve, solenoid, air tank, blow pipe, and differential pressure control.

Rotary airlock / rotary valve

Sealed material transfer at filter hopper outlets, silos, and pneumatic/enclosed discharge lines.

Screw conveyor, elevator, and conveyor

Dust control at screw conveyors, bucket elevators, enclosed conveyors, and transfer points in dust/clinker/cement handling.

Air slide fabric / air slide

Air permeability, pressure loss, and leak-tight flow control in cement and raw meal conveying lines.

Field measurement and retrofit

Revision scope determined by reporting flow rate, pressure loss, filter bag life, and emission issues on the existing filter/fan line.

How should capacity and specification data be read?

technical data	Information requested on the cement page	Why does it matter?
Airflow / capacity	m³/h process air, number of local suction points, duct diameter, fan nameplate	Filter area, air handling equipment capacity, and duct cross-section are determined based on this data.
Temperature	Continuous and peak temperature; distinction between clinker cooler, raw meal/coal mill, and kiln line	Changes the selection of filter bag media, cage coating, insulation, and safety equipment.
Dust characteristics	Raw meal, clinker, cement, coal, gypsum, limestone; particle size, moisture, and abrasiveness	Determines media, abrasion protection, hopper discharge, and cleaning regime.
Emission target	Regulatory/plant target, stack measurement, and leak complaints	Affects the choice between standard felt, microfiber, or ePTFE membrane.
Differential pressure	Existing ΔP trend, pulse period, and compressor capacity	A critical indicator for filter bag life, valve consumption, and energy cost.
Discharge and conveying	Rotary valve, screw conveyor, air slide, bucket elevator, conveyor capacity, and blockage history	Even if the filter is operating, insufficient hopper discharge causes dust leakage and downtime.
