Loader and Hopper

Highly durable compact loader

- Lineup of 1-line and 2-line conveyance system loaders
- Simple operation for reduced operator burden

Wide variation of hoppers

- Function array selectable according to application
- ZM-43/ZM-53 for stirring and mixing virgin or pulverized material

Example flow for 2-line conveyance system

■ 2-line conveyance loaders  LK-21, LK-22, LK-23

The LK-21, LK-22 and LK-23 require only one unit to convey material to two machines (i.e., dryers, molding machines, etc.) Select the ZM hopper with poppet valve.

■ Easy-to-operate controller

The touch panel on the top inclined face is designed to facilitate operation with a button layout for operation, setting and registration.

■ Hose

Specify hose length for non-standard applications.

■ Power cable

The standard power cable is 5 m long, but other lengths are available.

■ Color

Provide samples if desiring colors other than the STOLZ standard color (shown in photos).

■ Symbols for hopper models


■ Small type  ZH-04-P/ZH-05-P-A

These hoppers has a small effective capacity that is suited for compact loading machines. It is not capable of supplying multiple machines from standard specification loaders or dryers. To supply material to multiple machines, select from the ZM series.

■ Type P (Sight glass + Electrostatic proximity switch)

Type P hopper is equipped with a sight glass and an electrostatic proximity switch for detecting low material levels. It is used to supply molding machines with material. Since it is not outfitted with a shutter, the bottom can become airtight. To supply material to multiple machines, select from the ZM series.

■ Type LV (Sight glass + Paddle level gauge)

Type LV hopper is equipped with a sight glass and paddle level gauge for detecting low material levels. It is used to supply molding machines with material.

■ Type RS (Rotary shutter + Paddle level gauge)

Type RS hopper is equipped with a rotary shutter and is designed for use with a self-standing paddle level gauge. It is used to supply material from pellet tanks to stocking machines. Equipment modifications are required for installation.

■ Hopper plate and attachment for installation on molding machine

An installation plate and attachment are separately needed to install the hopper on molding machines that do not meet the standard specifications shown in the table, therefore indicate those specifications when ordering.
An installation plate is required for separately purchased hoppers.
Installation plates are separately required for the attachment with material drain and attachment with butterfly shutter.
The RS type hopper is for attaching to KA series pellet tanks.

ZM-43/ZM-53 system constitution

■ 2-material mixing

The ZM-43 and ZM-53 hoppers are for mixing virgin and crushed materials. Use them in a system configuration like that shown in the figure. Also, attachments require separate installation plates for some installation dimensions.
The ZM-43 andZM-53 are Built-to-Oder.

■ Installation plate

Installation plates are required where indicated in the figure.

■ Tank ans sight grass

Tanks and sight glasses can be selected.
Pellet tank  KA/KV/KX

■ Attachment with butterfly shutter

The attachment with butterfly shutter ensures sound operation without dust dispersal. Installation plates are separately required for some installation dimensions.
